Mercedes-Benz/AMG CLA 2019

[MotorPassion]

La nuova Mercedes-Benz CLA è 48 mm più lunga (4.688 metri), 53 mm più larga (1.830 che salgono a 1.999 con specchi aperti) e 2 mm più bassa (1.439 metri), rispetto alla precedente generazione del modello. Ciò significa che non solo avrà più spazio all'interno, ma ha anche proporzioni migliori rispetto al suo predecessore. Il passo è di 2.760 metri ed il baule ha una volumetria di 460 litri.

La variante nera con accenni arancio è la CLA 250 Edition 1, che presenta - oltre a questi particolari tocchi di colore - un allestimento specifico per paraurti e cerchi in lega.

La Mercedes-Benz CLA 250 è spinta da un motore 4 cilindri sovralimentato da 2,0 litri in grado di erogare 165 kW / 224 CV e 350 Nm di coppia ed è abbinato alla trasmissione automatica 7 rapporti doppia frizione. Il consumo medio, secondo specifiche WLTP, è compreso tra i 6.3 e 6.1 litri /100 km, mentre le emissioni sono di 140 / 143 g per km di CO2.

 

Un gradino sotto abbiamo la CLA 220, stesso motore, ma con potenza ridotta a 140 kW / 190 CV e 300 Nm di coppia.

Per ora MB non ha rilasciato altri dati, se non confermare che le due motorizzazioni hanno velocità massima limitata a 210 km/h.

Las Vegas. The new Mercedes-Benz CLA Coupé is not only the most emotional vehicle in its class, it is also highly intelligent: From MBUX Interior Assist, which recognises operational demands from gestures and equips the interior with intelligence, through augmented reality for navigation and understanding indirect voice commands to the ENERGIZING COACH that provides individual fitness recommendations, the new CLA offers an array of clever solutions. There are also ingenious details when it comes to the aerodynamics and new functions for the Intelligent Drive driving assistance package. The design underlines the coupé character with its stretched form and design elements such as the bonnet with powerdomes or the rear licence plate which has been moved down. As such it does justice to its predecessor’s status as a design icon.

With MBUX, Mercedes-Benz has been revolutionising how to operate a car and communicate with it since the launch of the A-Class. “Now we go to the next level with an intelligent interior assistance system for the compact class. By recognising gestures it facilitates natural operation,” says Ola Källenius, Member of the Board of Management of Daimler AG, responsible for Group Research and Mercedes-Benz Cars Development. “This is not the only new feature by which the CLA offers a great deal of automotive intelligence.”

“With the first CLA we created a totally new segment with a four-door coupé and celebrated a huge success by selling some 750,000 CLA and Shooting Brake,” adds Britta Seeger, Member of the Board of Management of Daimler AG, responsible for Mercedes-Benz Cars Marketing & Sales. “The new edition of the CLA has been developed further in an intelligent way and is even more emotional and sportier than its predecessor. Coupled with new operating systems, it sets new benchmarks for the entire class.”

The new generation of compacts has made a key contribution to the rejuvenation and image change of the Mercedes-Benz brand. The CLA is important for winning and retaining new customers in particular. The CLA Coupé was launched in the USA in 2013, making it the first compact Mercedes‑Benz on the American market. At peak times, more than two thirds of CLA buyers in the USA came from competitors. On average, CLA customers in the USA are around ten years younger than the typical Mercedes‑Benz customer. In Europe, too, CLA customers are among the youngest in the Mercedes portfolio. In 2017, one in two customers in Europe previously drove a competitor's vehicle. Over 75 percent of European customers who previously drove a CLA as a coupé or Shooting Brake chose a Mercedes‑Benz again for their next vehicle. In total, some 750,000 units of the first-generation CLA Coupé and CLA Shooting Brake contributed considerably to the compact car's success.

In its first year, the new CLA will also be available as an Edition 1. In terms of both the exterior and the interior, this limited edition special model has numerous visual accents which underline its exclusivity. The new CLA will be manufactured at the Kecskemét plant (Hungary) and comes onto the market in May 2019.

Design: pure emotion

“As a four-door coupé, the new CLA intrigues with its puristic, seductive design and sets new standards in the design DNA of ‘ sensual purity’. It impresses with its perfect proportions reflecting the first design sketch: a long, stretched bonnet, a compact greenhouse, a wide track with exposed wheel arches and our typical GT rear end with a strong distinctive ‘Coke-bottle shoulder’ � ,” says Gorden Wagener, Chief Design Officer of Daimler AG. “In short - the CLA Coupé has the potential to become a modern design icon.”

The combination of the long, stretched entry line above the windows and frameless doors give the CLA Coupé its unmistakeable sporty and elegant character. Forming the front end is the striking front section which is raked forwards like a shark nose with a long, stretched bonnet featuring powerdomes.

Flat headlamps together with the low slung bonnet and the diamond radiator grille with central star create the vehicle’s sporty face. The two-piece, narrow tail lamps and the number plate housed in the bumper make the rear of the CLA look especially wide.

With the greenhouse moved back, the sporty GT rear achieves a balance between elegance and sportiness. Featuring pared-down lines, the precisely modelled side profile provides an interesting interplay of light and shade. Dispensing with the upper shaped edge of the side wall permits extremely muscular and athletic shoulder shaping, stretching from the front wheel arch through to the sculptured rear. Flush with the outer edge of the body, the wheels with their flared wheel arches and wide track epitomise dynamism and give the vehicle a sporty presence.

In the interior, all elements are arranged according to the overarching design themes of ‘high tech’ and ‘youthful avant-garde’ – be that the steering wheel, the door handle operating module, the centre console or the seats. As in the A‑Class, the unique interior architecture is shaped in particular by the avantgarde design of the dashboard: The designers completely dispensed with a cowl above the cockpit. As a result, the wing-shaped main body of the dashboard extends from one front door to the other with no visual discontinuity. The widescreen display is completely free-standing. The lower section is visually separated from the main body of the instrument cluster by a ‘trench’, and it appears to float in front of the instrument cluster. The ambient lighting enhances this effect. The air vents in a sporty turbine-look are another highlight.

Suspension: exceptionally agile and yet comfortable

In terms of driving dynamics, too, the new CLA keeps the promise of its design: A wide track (an extra 63 mm at the front and 55 mm more at the rear compared to its predecessor) and a lower centre of gravity are the two key features which give the CLA the sportiest driving characteristics of all models in the new generation of compacts from Mercedes-Benz. The technical specification includes a decoupled multi-link axle at the rear for reduced noise and vibration, a Direct-Steer system as standard and hydromounts at the front. A stabiliser bar with a larger diameter reduces body roll. As an option, an active adaptive damping system is available, giving the driver the choice between comfort or a more uncompromising sporty tuning. The range of wheels starts at 16 inches and goes up to 19 inches with tyre sizes starting at 205/60 R 16 and ending as standard at 225/40 R 19. The ESP^® has been specially adapted to the CLA’s potentially high cornering speeds and handling performance.

One year since the première: MBUX keeps on learning

One year ago, MBUX – the Mercedes-Benz User Experience – created a furore at its world première at CES in Las Vegas. A powerful computer, brilliant screens and graphics, customisable display, full colour Head-up Display, navigation with augmented reality, software that can learn and “Hey Mercedes” – the keyword for voice control that explodes conventional automotive standards. This is how Mercedes-Benz is revolutionising car operation and communication with it. Now the company is igniting the next level. MBUX Interior Assist facilitates natural operation. The voice control feature now recognises topical answers in a growing number of domains. Due to ongoing development of the system, it is also possible to take into consideration country-specific content providers.

“The latest version of voice control for MBUX – the Mercedes-Benz User Experience – can be experienced in the new CLA. For example, the voice assistant ‘Hey Mercedes’ is able to recognise and answer considerably more complex queries,” says Sajjad Khan, Member of the Divisional Board of Mercedes-Benz Cars for CASE and Head of Digital Vehicle & Mobility. “What's more, the voice assistance no longer gets confused by other passengers conversing. Instead it only responds to the commands of the person who last said ‘Hey Mercedes’ to activate the system.”

MBUX Interior Assist: an even greater experience

By recognising movements MBUX Interior Assist brings added intelligence to the interior. Thanks to innovative technology, MBUX now supports the occupants by making various comfort and MBUX functions even simpler and more intuitive. Interior Assist operates in non-contact mode and functions both in sunlight and in complete darkness.

It enables the adaptation of screen content as soon as a hand approaches the touchscreen in the dashboard or the touchpad on the centre console, for example. Individual elements are highlighted according to the currently active menu. In addition, the system is able to distinguish between the driver’s and front passenger’s wishes and thus knows for whose seat the massage function is to be activated, for example.

A special feature of Interior Assist is the personal favourites function. It is accessed by holding a hand over the centre console with the index and middle finger spread in a V-shape. In this way, any command which is controllable via MBUX can be stored for simple access. One typical favourite command is ‘navigate me home’. As the system is able to reliably recognise who is operating it, the driver and front passenger respectively can even assign different favourites to the same hand position.

There are other functions which can be controlled intuitively, without any need to practise corresponding gestures: In the dark, the reading lamp can be switched on and off by briefly extending a hand towards the rear-view mirror, for example. If the driver reaches over towards the unoccupied front passenger seat in the dark, it will be illuminated automatically. This makes it easier to find any items which may have been deposited on the seat. As soon as the person’s hand leaves this area, the light automatically switches off again.

"Hey Mercedes": better understanding and even cleverer responses

State-of-the-art of voice control can also be experienced in the CLA. Here too seat recognition has been implemented. The voice assistance only responds to the commands of the person who last said ‘Hey Mercedes’ to activate the system. In the American market initially, the voice assistant can recognise and respond to considerably more complex queries, for example: ‘Find child-friendly Asian restaurants nearby with 4-star rating which are neither Chinese nor Japanese. ’ There is also a growing number of domains for which MBUX can understand complex questions and quickly reply: calculations (‘What is the square root of 3? ’) or general knowledge (‘How big is Texas? ’, ‘What is the fat content of avocados? ’).

ENERGIZING comfort control: wellness while driving

• Energizing comfort control links various comfort systems in the vehicle. The intelligent recommendations from the Energizing COACH in the ENERGIZING Package Plus are completely new. In general, the ENERGIZING comfort control systematically uses the functions of the air conditioning system and the seats (heater, ventilation, massage) as well as lighting and musical moods, and enables a specific wellness set-up tailored to the mood and need of the customer.
• ENERGIZING packages: the next step in intelligent comfort
• ENERGIZING packages with the ENERGIZING COACH are new. This service based on an intelligent algorithm recommends one of the ENERGIZING packages’ programmes depending on the situation and individual. The Mercedes-Benz vivoactive^® 3 Smartwatch has its world première at CES. If it or another compatible Garmin^® wearable is worn, personal stats such as stress level or quality of sleep optimise the accuracy of the recommendation. The aim is for passengers to feel well and relaxed even during demanding or monotonous journeys. In addition, the pulse rate supplied by the integrated Garmin wearable is shown on the media display.

Aerodynamics: intelligent solutions intelligently designed

On the way to series production, the aerodynamics of the new CLA underwent a considerably longer phase of optimisation than its predecessor in the form of simulations, before the first measurements of models were carried out in the wind tunnel. This was possible due to greater computing capacity, as well as in particular more experience of working with simulation tools and their best possible and most efficient use in the development process.

A key advantage of the simulation process is that it is easy to determine the exact proportions of the form, and to examine the effects of a change in form on flow at another point which is either before or after in the direction of flow, without it being necessary to make changes to the physical model. The result also sets standards: A _Cd value of 0.23.

Work on optimisation was in close collaboration with the designers and was particularly intensive on the rear apron, radiator grille, the fog lamp recesses (the relief-like diamond-shaped pattern of which was reduced to the edge on the CLA for aerodynamic reasons) and the height of the diffuser. Totally new are the wheel-arch spoilers with their fins in the longitudinal direction; they help air to flow around the wheels with minimal losses. Aerodynamic finessing was also performed on the wheels and tyres – both for the regular wheel-tyre combinations and for what are known as aero wheels, which have been completely redesigned to achieve the best possible aerodynamic values and which also look attractive. Integrated as standard at the front of the vehicle is a two-piece shutter system behind the radiator grille, which regulates air flow through the engine compartment. The almost complete underbody panelling encompasses the engine compartment, the main floor, parts of the rear axle and the diffuser.

Intelligent Drive: functions from the S-Class

The CLA has the very latest driving assistance systems with cooperative driver support, and thus provides the highest level of active safety in this segment with functions adopted from the S‑C lass. For the first time, the CLA is able to drive semi-autonomously in certain situations. To do this, it keeps a close eye on the traffic situation. Improved camera and radar systems allow it to see up to 500 metres ahead. The CLA also uses map and navigation data for assistance functions. For example, Active Distance Assist DISTRONIC as part of the optional Driving Assistance Package is able to provide route-based support to the driver in numerous situations, and to predictively and conveniently adjust the speed, e.g. when approaching bends, junctions or roundabouts. Also on board are e.g. Active Emergency Stop Assist and intuitively understandable Active Lane Change Assist.

The new CLA comes with enhanced Active Brake Assist as standard. Depending on the situation, it can effectively help to mitigate the consequences of rear-end collisions with slower-moving, stopping or stationary vehicles ahead, and even with crossing pedestrians and cyclists, or to prevent them altogether.

Active Lane Keeping Assist (likewise standard) is able to warn the driver by means of pulsed vibrations in the steering wheel when the vehicle is unintentionally drifting out of its lane at speeds between 60 and 200 km/h. If the vehicle passes over a solid line, it can pull the vehicle back into lane by applying the brakes on one side. In the case of a dotted line, such intervention takes place only when there is a danger of collision with a vehicle in the adjacent lane (including danger from oncoming traffic).

PRE-SAFE^® PLUS can recognise an imminent rear-end collision. If the danger of a collision persists, the system can also firmly apply the brakes of the stationary vehicle, thus lowering the risk of injuries by reducing the forward jolt caused by an impact from the rear.

MULTIBEAM LED headlamps: better visibility in all conditions

Another example of automotive intelligence and the transfer of technology from the luxury segment to the compact class are the optional MULTIBEAM LED headlamps. They allow extremely quick and precise, electronically controlled adjustment of the headlamps to suit the current traffic situation. Each headlamp on the CLA incorporates 18 individually controllable LEDs. The daylight-like light colour of the LEDs is easy on the eyes and has a positive effect on concentration. The road ahead is precisely and brightly illuminated. LED High Performance headlamps are a further option. As standard, the new CLA is equipped with halogen headlamps with integrated LED daytime driving lamps. The tail lamps are also available with all-LED technology.

Drive system: start with the most powerful engine

At the trade show presentation in Las Vegas, the CLA on display is the CLA 250 with the powerful four-cylinder petrol engine (165 kW/225 hp, 350 Nm) with 7G-DCT dual-clutch transmission (combined fuel consumption 6.3-6.1 l/100 km, combined CO₂ emissions 143-140 g/km)^[2]. By the market launch in May, there will be a broad range of diesel and petrol engines available featuring manual or dual-clutch transmissions and 4MATIC all-wheel drive.

Affalterbach. Sporty, stylish, intelligent and dynamic: The new CLA 35 4MATIC (combined fuel consumption 7.3-7.2 l/100 km; combined CO₂ emissions 167-164 g/km)[1] is the latest point of entry to the world of Mercedes-AMG and is more strongly lifestyle-oriented. The four-door coupé shares the progressive technology with the A-Class produced in Affalterbach, but is even bolder with its iconic design and the intelligent MBUX interior assistant. The agile high torque 2.0-litre four-cylinder turbo engine delivers 225 kW (306 hp), which is variably distributed to all four wheels via the 7-speed dual-clutch transmission and the all-wheel drive. The sporty driving performance (acceleration from 0-100 km/h in 4.9 seconds) is linked with a wide spread of the driving experience - from very sporty to comfortable on long journeys.

"With its iconic design and agile driving dynamics, the new CLA 35 is an attractive offer for a young, active and lifestyle-conscious target group. These customers define their requirements very clearly: They expect exciting design from their vehicle alongside superior performance and inspiring handling characteristics. The new CLA 35 embodies just this attitude to life – and enables stepping in to the fascinating world of AMG Driving Performance in a particularly emotional way", says Tobias Moers, CEO of Mercedes-AMG GmbH.

Icon with a slim sporty waistline: the exterior design

The iconic design of the CLA Coupé is one of the main reasons for purchasing the car. The AMG designers therefore more or less kept the basic form with wide wheel arches and a slim sporty waistline. The two powerdomes on the bonnet were also adopted as sporty details. By way of contrast, the new radiator grille with the classic twin louvres and the AMG Line front apron with flics on the air inlets are typical distinctive features of the CLA 35 4MATIC. Other distinctive features include trim elements in silver chrome on the louvres in the outer air inlets. From a side view, the aerodynamically optimised 18-inch light-alloy wheels in twin-spoke design (19-inch optionally available) and the accentuated side sill panels catch the eye. The rear view is dominated by the rear apron with a new diffuser insert, the small spoiler lip on the boot and the two round tailpipe trims on the left and right. The two-piece, narrow tail lamps and the number plate housed in the bumper make the rear of the CLA look especially wide.

Sporty interior with MBUX infotainment system

Frameless doors open to an interior with a high-tech ambience where quality and elegance meet fully digital displays. This interior optionally stages the ambient lighting in 64 colours. Another characteristic feature are the seat covers which are available in ARTICO man-made leather with DINAMICA microfibre in black with red contrasting stitching and red seat belts or in ARTICO mad-made leather in black/digital grey. Red piping on the microfibre DINAMICA trim element and ventilation nozzles with a red ring add further accents.

The combination of sporty design and sophisticated details is also featured in the MBUX infotainment system with its innovative operating and display concept. In the new CLA 35 4MATIC too MBUX replaces the previous COMAND systems and creates an even closer connection between the vehicle, driver and passengers. Emotionally appealing presentations underline the clear control structure and feature brilliant maximum-resolution 3D graphics. Visually, the two displays under one shared glass cover blend into a Widescreen Cockpit and as a central element consequently emphasise the horizontal orientation of the interior design.

With the new optional MBUX interior assistant, select infotainment functions can be operated touchlessly and the reading light can be switched on and off. The assistant differentiates between driver and passenger interaction and recognises certain hand positions and movements. The interaction area for the MBUX interior assistant is in front of the media display up to the centre console, including the touchpad between the driver and the front-seat passenger.

The MBUX interior assistant recognises movement toward the various operating elements of the infotainment system. The operator's seat is enlarged on the media display if one’s hand is moved toward the touchscreen. The most suitable operating elements are automatically pre-selected. In the Radio and Media menu, the MBUX interior assistant reduces the number of operating steps. In the Navigation menu, the system fades in the navigation as soon as the hand moves to operate the touchscreen or touchpad, so that a symbol is selected directly. When displaying the camera image, as soon as the hand moves toward the touchscreen the MBUX interior assistant enables the four camera operating symbols from the 360-degree camera to be directly faded in. This means that the front, rear, right or left camera view can be directly selected.

And needless to say, the CLA 35 4MATIC also comes with trailblazing voice control, activated with the words "Hey Mercedes". Thanks to artificial intelligence, MBUX recognises and understands nearly all sentences from the fields of infotainment and vehicle operation, even if they are expressed indirectly.

Fully digital instrument cluster with three AMG display styles

The customer can choose between the three AMG display styles "Classic", "Sport" and "Supersport" for the instrument cluster. The "Supersport" mode is particularly striking with a central, round rev counter and additional information presented in the form of bars to the left and right of the rev counter: with a three-dimensional perspective, they reach far into the background to an artificial horizon. Via the AMG menu, the driver can call up various special displays such as Warm-up, Set-up, G-Force and Engine Data.

Touchscreen multimedia display and new centre console

The touchscreen multimedia display also emphasises the dynamic character with individual AMG displays such as visualisation of the driving programs, AMG TRACK PACE and telemetry data.

The AMG-specific centre console in piano lacquer finish with standard touchpad has additional buttons that control the functions ESP^®, manual transmission mode and Adaptive Damping System. In conjunction with the optional leather package, it features a silver chrome surround.

New AMG steering wheel generation with optional steering wheel buttons as standard

The new generation of AMG steering wheels provides the perfect link between the driver and the vehicle. The steering wheel rim with a flattened lower section, perforated leather in the grip area and red contrasting topstitching is both attractive and pleasant to the touch. The galvanised steering wheel gearshift paddles allow an even sportier driving style with manual gear shifting.

The built-in Touch Control buttons, familiar from other model series, are a new feature. The active distance assistant DISTRONIC and the TEMPOMAT cruise control can be adjusted on the control panels on the left. The control panels on the right are used to activate the voice control and telephone, and to regulate the sound volume, music selection and other functions of the infotainment system.

The steering wheel with the innovative AMG steering wheel buttons is available as an option. These consist of a round controller with an integrated display beneath the right-hand steering-wheel spoke, plus two vertically positioned colour display buttons with switches beneath the left-hand steering-wheel spoke. The AMG drive programs are actuated directly via the controller. With the two freely configurable display buttons and the additional switches, further AMG functions can be controlled within easy reach, directly on the steering wheel.

Reinforced body-in-white with increased torsional stiffness

Specific measures to strengthen the front section of the bodyshell form the basis for the precise turn-in ability and the toe and camber stability of the chassis components, even when driving at speed. A so-called "shear panel", a bolted aluminium plate under the engine, increases the torsional stiffness of the front section of the CLA 35, too. Two additional diagonal braces at the front of the underbody also reduce torsion and increase the stiffness.

New four-cylinder turbo engine with output of 225 kW (306 hp)

The 2.0-litre turbo engine is a new development and is based on the M 260 four-cylinder engine in the new A-Class. The new drive boasts a spontaneous response to accelerator pedal commands, high tractive power (400 Nm max. torque from 3,000 rpm), a supremely lively response and an emotional engine sound. The crankcase made of high-strength, lightweight die-cast aluminium reduces the vehicle weight where it matters most for driving dynamics.

A twin-scroll turbocharger is used for turbocharging. It combines optimum responsiveness at low engine speeds with a strong power increase at higher speeds. The housing of the twin-scroll turbocharger is divided into two parallel ducts. Together with two separate exhaust ducts in the exhaust manifold, this makes it possible to channel the exhaust gases separately on the turbine wheel.

This results in a further advantage of twin-scroll technology, i.e. minimisation of the mutually adverse effects of the individual cylinders on the gas cycle. The exhaust gas back pressure is reduced and gas exchange and engine efficiency are improved.

Numerous engine measures increase efficiency

The high technological standards of the new four-cylinder engine are also underscored by numerous efficiency-enhancing measures. These include CAMTRONIC variable valve control, intelligent thermal management for engine and oil, high-precision piezo injectors and multi-spark ignition. In production, the patented CONICSHAPE^® cylinder honing reduces internal engine friction and also increases efficiency.

Agile gear ratios: AMG SPEEDSHIFT DCT 7G dual-clutch transmission

The AMG SPEEDSHIFT DCT 7G dual-clutch transmission also contributes to the agile and dynamic character of the new CLA 35 4MATIC. The gear ratios have been configured so that the driver experiences very spontaneous acceleration in all speed ranges, combined with fast shifting and optimum connections when shifting up.

The standard RACE-START function allows maximum acceleration from stationary and is a highly emotional experience. The functions of the AMG SPEEDSHIFT DCT 7G transmission are rounded off with a temporary M mode activated by operating the steering wheel shift paddles in any driving mode, and with the manual transmission mode "M" for manual gear shifting with the shift paddles.

AMG Performance 4MATIC variable all-wheel drive

Dynamism, agility and performance – these three attributes characterise the standard all-wheel drive of the new AMG CLA 35 4MATIC. The variable AMG Performance 4MATIC combines the best possible traction with lots of driving fun. The torque distribution is infinitely variable to suit the dynamic handling requirements. The spectrum ranges from front-wheel drive only to a 50:50 percent distribution to the front and rear axles.

A multi-disc clutch that is integrated in the rear axle transmission is responsible for the variable torque distribution between the front and rear axles. It is controlled electro-mechanically. The influencing factors for torque distribution are not only the driving speed, the lateral and longitudinal acceleration and the steering angle, but also the difference in rotational speed between the individual wheels, the gear selected and the accelerator position.

The main advantages of electro-mechanical control over an electro-hydraulic system relate to more refined driving dynamics – primarily due to the significantly faster response and speed-independent actuation of the discs over the entire adjustment range.

As long as ESP^® is activated, the 4MATIC system stays in "Comfort" mode. As soon as the driver presses the "ESP^® SPORT Handling" or "ESP^® OFF" button, the 4MATIC system switches to "Sport" mode – for even more agile handling and even higher stability limits.

Five driving programs: vehicle characteristics with wide spread

The five AMG DYNAMIC SELECT drive programs "Slippery", "Comfort", "Sport", "Sport +" and "Individual" enable a wide range of vehicle characteristics from comfortable to dynamic. They change relevant parameters, such as the response of the engine and transmission.

The new "Slippery" drive program is optimised for low-grip, icy road conditions, with reduced power and a flat torque curve. Smooth gear changes and earlier upshifting support the driving impression characterised by stability.

The "Comfort" program stands for comfortable and fuel-efficient driving, for example thanks to very early upshifts. Suspension and steering are set up for an emphasis on comfort.

"Sport" and "Sport+" place the focus on agility and driving pleasure with sporty engine and transmission tuning. The sound of the turbo engine is more striking. "Sport+" is particularly emotional with double-declutching during downshifts and partial cylinder cut-off via a brief and precisely defined retardation of ignition and injection at full load.

The "Individual" drive program enables the individual parameters to be selected and saved according to personal preferences. In addition, the gliding function is available in the "Reduced" and "Moderate" drive settings.

AMG DYNAMICS: more agility with high stability

As a new feature in the AMG DYNAMIC SELECT drive programs, the new CLA 35 4MATIC comes with AMG DYNAMICS. This integrated dynamic handling control system extends the stabilising functions of ESP^® with agilising interventions according to the driver's wishes. During dynamic cornering, imperceptible braking intervention on the rear inside wheel creates a defined yawing moment about the vertical axis. The effect: the CLA 35 4MATIC steers spontaneously and very precisely.

The different manifestations of AMG DYNAMICS are called "Basic" and "Advanced". On the multimedia display, when a drive program is selected, the new AMG DYNAMICS symbol is displayed together with the corresponding additional information.

• "Basic" is assigned to the "Slippery" and "Comfort" drive programs. In this case, the CLA 35 4MATIC shows very stable handling with high damping of the yaw rate.
• "Advanced" is activated in the programs "Sport" and "Sport+". The CLA 35 4MATIC remains neutrally balanced. The lower yaw damping, lower steering angle requirement and enhanced agility support dynamic manoeuvres such as driving on winding country roads

In the "Individual" drive program the driver can set the AMG DYNAMICS levels individually.

AMG RIDE CONTROL suspension with specific components

The layout of the AMG RIDE CONTROL suspension forms the solid straight-line stability and the highly dynamic cornering performance. The longitudinal and transverse dynamics are perfectly coordinated.

A McPherson suspension strut construction is fitted on the front axle. Suspension is taken care of by one wishbone below the wheel centre, one spring strut and one tie rod respectively. The special axle geometry reduces the influence of the drive on the steering – for high comfort and agile handling. The new wishbone in aluminium reduces the unsprung masses enabling a more sensitive response from the springs. The AMG-specific front steering knuckle has a radially bolted brake calliper – a technology originating from motorsport.

The 4-link rear axle is connected rigidly with the body via a subframe. Three transverse arms and the trailing arm, the wheel carrier and the bearings from the proven A 45 4MATIC are used on each rear wheel. This ensures maximum driving stability and agility.

Adaptive damping system with three modes

The optional Adaptive Damping System enables the driver to choose between three different suspension control modes. The spectrum ranges from comfort-focused to sporty. The system operates fully automatically, adapting the damping forces for each wheel according to the driving situation and road conditions. This happens within milliseconds and is infinitely variable, with a wide spread of damping characteristics. The result is that ride comfort and agility are enhanced in equal measure.

Robust high-performance brake system

The high-performance braking system ensures fade-resistant deceleration and short braking distances. Its dimensions correspond to the well-proven A 45 4MATIC model. The front axle is fitted with new 4-piston monoblock fixed callipers and 350 millimetre brake discs, the rear axle with 1-piston sliding callipers and 330 millimetre brake discs. The discs are internally ventilated and perforated to better dissipate heat and prevent brake fading, even with extreme use. The silver-painted brake callipers have black AMG lettering.

Steering with special rack and variable ratio

The speed-sensitive, electro-mechanical sports power steering supports a sporty driving style with its direct turn-in ability. It has a special rack with variable transmission ratio and two characteristic curves: depending on which drive program the driver has selected, it provides taut and sporty or more comfortable steering feedback. The rigid mounting in the integral carrier connects the steering even better with the body and thus increases steering precision.

AMG exhaust system with exhaust flap for sound modulation

The exhaust system features an automatically controlled exhaust flap as standard. Depending on the drive program selected, it modulates the sound from balanced to powerful.

Data logger for use on the race track: AMG TRACK PACE

AMG TRACK PACE is also available as an option for the new CLA 35 4MATIC. The virtual race engineer is part of the MBUX infotainment system and permanently records more than 80 vehicle-specific data (e.g. speed, acceleration) while driving on a racetrack. On top of this, lap and sector times are displayed, as well as the respective difference to a reference time. Because specific display elements are shown in green or red, the driver is able to see at a glance without reading numbers whether they are currently faster or slower than the best time.

After putting in some fast laps, the driver can use the data to analyse and, if necessary, improve their driving skills. In addition, acceleration and deceleration values (e.g. 0-100 km/h, ¼ mile, 100-0 km/h) can be measured and saved. Thanks to a newly developed algorithm which determines the vehicle position as precisely as possible, AMG TRACK PACE even detects when the circuit has been left or it has been shortened. This is done using GPS data as well as the sensors available in the vehicle (acceleration, gyroscope, steering angle, wheel speeds).

The data are displayed on the multimedia display, in the instrument cluster and on the optional head-up display. Well-known racetracks like, for example, the Nürburgring or Spa Francorchamps, are already stored. Furthermore, it is also possible to record one’s own circuits. The map display can be switched from 2D to 3D and updated online.

The MBUX Augmented Reality function also allows the ideal line of a stored racetrack to be displayed on the multimedia display or optional head-up display, allowing the driver to improve lap times with a virtual instructor on board.

Cita

Affalterbach.  Outstanding performance, the ultimate driving dynamics, expressive design ‑ the new Mercedes-AMG compact A 45 4MATIC+/ A 45 S 4MATIC+ sports cars (combined fuel consumption 8.4-8.3 l/100 km; combined CO₂ emissions 192-189 g/km)[1] and CLA 45 4MATIC+/ CLA 45 S 4MATIC+ (combined fuel consumption 8.3-8.1 l/100 km; combined CO₂ emissions 189-185 g/km)[1] reassert their leading positions in their segments. They seamlessly continue the success story of their predecessors, while setting numerous new standards. Available in two output and torque variants, the completely newly developed 2.0-litre engine is the world's most powerful turbocharged four-cylinder engine in manufactured for series production. Even the basic model with 285 kW (387 hp) is more powerful than its predecessor. The S-variant with 310 kW (421 hp) jostles with considerably higher vehicle classes. Perfect sequences in all driving situations, and fast gearshifts measured in milliseconds, are guaranteed by the new AMG SPEEDSHIFT DCT-8G dual-clutch transmission with eight gears. The active, fully-variable AMG Performance 4MATIC+ all-wheel drive distributes the power to the rear axle wheel-selectively by AMG TORQUE CONTROL – for top traction and the spectacular Drift mode. This is made possible by a new rear axle differential featuring two multidisc clutches – one for each rear wheel.

With its new compact sports models Mercedes-AMG is demonstrating its high competence in development once again: "We have completely redesigned our "45" models – from the engine and transmission through the chassis, the elaborately constructed drivetrain to the body structure and of course the design itself – all with one goal: to raise vehicle dynamics and the sporty driving experience to a level previously unimaginable in the compact class. With the presentation of this, our most powerful and most dynamic compact sports car, we are also reinforcing the significance of this segment for our growth strategy", says Tobias Moers, Chairman of the Management Board of Mercedes-AMG GmbH.

Exterior design: AMG family membership even more apparent

The new Mercedes-AMG A 45 4MATIC+ and CLA 45 4MATIC+ models are even more distinctive than their predecessors. The exterior conveys sheer driving pleasure even at standstill. For the first time, the compact class now also features the AMG-specific radiator grille with a wider lower contour and twelve vertical louvres – as a clear indicator of AMG Performance family membership. At the same time, the pronounced "shark nose", the slim, deeply contoured headlamps and the flat, aerodynamically favourable bonnet with powerdomes visually lower the front section to create the impression of extremely dynamic forward thrust.

The imposing presence is also accentuated by the wider front wings with flared wheel arches. These create space for the wider front axle, and underline the athletic appearance. This muscular impression is even stronger with the A 45 4MATIC+ than with the CLA 45 4MATIC+, as the basic CLA already has a wider front track and the wings could be flared to a lesser extent.

Individual details as distinguishing features

The front apron is also a distinguishing feature. In the A 45 4MATIC+ it is in a jet-wing design. Horizontal fins in the outer air inlets and the stretched lower air inlet emphasise the impression of width. The CLA 45 4MATIC+ has an even more expressive appearance with its jet-like external air inlets, showing its close family relationship with the AMG GT 4-door Coupé. The front splitter transitions seamlessly into the side air curtains ahead of the front wheels, which optimise the airflow to improve aero-performance and the Cd figure.

Viewed from the side, the wider AMG side skirts visually lower these compact sportscars so that they appear to hug the road more closely. If the Silver Chrome package is specified, the inserts are in silver chrome, and with the AMG Night package they are in high-gloss black.

The exterior mirrors are mounted on the door muscle, echoing the look of Mercedes-AMG coupés and sportscars. This not only looks very sporty, but also improves the aerodynamics.

As standard the basic variants feature 8.5 J x 18-inch light alloy wheels in a 10-spoke design, aerodynamically optimised and painted in tantalum grey with size 245/40 R 18 tyres.

The S-models are equipped with 19-inch light alloy wheels in a 5-twin-spoke design ‑ with a width of 8.5 inches for the A 45 S 4MATIC+ and nine inches for the CLA 45 S 4MATIC+. The attractive aluminium rims are aerodynamically optimised and painted in tantalum grey with a high-sheen finish, and shod with tyres in size 245/35 R 19 and 255/35 R 19 (CLA 45) respectively. In the basic models the AMG high-performance braking system features grey-painted brake callipers with white AMG lettering. The S-versions are recognisable by their larger, red-painted 6-piston brake callipers with black AMG lettering.

Round twin exhaust tailpipes for the Performance compact cars

The rear view is characterised by two round twin tailpipes (82 mm diameter) and the wide rear apron. The S-models are distinguished by their larger, 90 mm exhaust tailpipes with internal fluting and AMG lettering. The impression of width at the rear is emphasised further by the slim two-piece rear light clusters. The diffuser with two vertical twin fins contributes to better aero-performance (CLA 45: four individual fins) - it is extended forward at the centre of the vehicle, making it work more effectively. The effect is rounded off by the spoiler lip in the vehicle colour on the roof spoiler, or on the boot lid (CLA 45).

The most important optional exterior features:

• AMG Aerodynamic package for optimised aerodynamic balance, included a modified front splitter and additional flics on the front apron, an additional diffuser blade, side spoiler lips on the rear apron and rear spoiler (A 45) or larger spoiler lip (CLA 45) in high-gloss black. These features increase the downforce, and therefore handling stability at the physical limits
• 19-inch light-alloy wheels in a 5-twin-spoke design, aerodynamically optimised, painted either in tantalum grey with a high-sheen finish or in matt black with high-sheen rim flange
• 19-inch forged wheels in a cross-spoke design, painted either in titanium grey with high-sheen finish or in matt black with high-sheen rim flange, with simulated central wheel lock in aluminium
• AMG Night package with design features in high-gloss black ‑ for example the front splitter or inserts in the sideskirts ‑ and black chromed exhaust tailpipes
• Silver Chrome package with front splitter and inserts in the sideskirts in silver chrome

Bodyshell: extensively reinforced

The AMG developers extensively reinforced the bodyshell, as it provides the basis for the precise self-steering characteristics, as well as track and camber stability, also when driving at high speed. A lightweight aluminium plate bolted underneath the engine - the "shearing plate" - increases the torsional rigidity at the vehicle's front end. This is supplemented by a strut tower brace between the front suspension struts and pistol-shhaped "shotguns"  ‑ these are additional reinforcing plates connecting the side members to the A-pillars to minimise movements of the front section. Diagonal struts at the front and rear of the underbody further improve rigidity. As a result the entire suspension system responds highly precisely even at the physical limits, giving the driver clearly defined feedback – with considerably reduced body torsion around the longitudinal and transverse axis, and less rolling and pitching on bends, when braking and during load cycles.

Drive system: new turbocharged four-cylinder with ample power

With an output of up to 310 kW (421 hp), the completely newly developed 2.0-litre engine is the world's most powerful turbocharged four-cylinder manufactured for series production. Mercedes-AMG has bettered the output of the preceding engine by 30 kW(40 hp). Maximum torque has also increased from 475 to up to 500 newton metres. With an output per litre of up to 155 kW (211 hp), the new Mercedes-AMG high-performance turbo engine even ranks ahead of many well-known super-sports car engines. The new, highly efficient powerpack is produced on an innovative production line in Affalterbach, on the "One Man, One Engine" principle.

In the 45 models, the four-cylinder ensures extremely agile performance in two output classes: with 310 kW (421 hp) as the S-model and with 285 kW (387 hp) in the basic version.

This positioning logic has already proved successful for the AMG Performance models with a V8 engine, and meets individual customer wishes even better. The new compact sportscars absolve the sprint from zero to 100 km/h in record time: the A 45 S 4MATIC+ requires only 3.9 seconds (CLA 45 S 4MATIC+: 4.0 seconds), while the basic A 45 4MATIC+ model absolves this discipline in 4.0 seconds (CLA 45 4 MATIC+ in 4.1 seconds). The top speed of the basic models is electronically limited to 250 km/h, while the S-models are capable of up to 270 km/h ex factory. With the optional AMG Driver‘s Package, the top speed can also be increased to 270 km/h for the basic variants.

Apart from its performance figures, the new engine impresses with its immediate response. To this end the torque curve was carefully balanced ("torque shaping"): The maximum torque of 500 Nm (480 Nm in the basic variants) is available within a range of 5000-5250 rpm (4750-5000 rpm in the basic variants). With this configuration the AMG engineers have achieved a power delivery akin to a naturally aspirated engine. The engine developers were able to realise a dynamically increasing torque curve in the lower engine speed range, thereby improving throttle response. The increasing torque at higher rpm makes the engine more free-revving. Moreover, the high maximum engine speed (up to 7200 rpm) emphasises the engine's sporty character.

Engine design: intelligent details

The new engine excels with numerous intelligent design features. Unlike the likewise transversely installed four-cylinder in the 35 models or the preceding model, the new engine is rotated around its vertical axis by 180 degrees. This means that the turbocharger and the exhaust manifold are now positioned at the rear, on the side of the firewall when viewed from behind. The intake system is therefore positioned at the front. This configuration allows the flattest possible and aerodynamically advantageous front section design. Furthermore, the new arrangement allows much improved air ducting with shorter distances and fewer diversions - both on the intake and exhaust side.

Turbocharger: roller bearings reduce mechanical friction

The new twinscroll turbocharger combines optimum responsiveness at low engine speeds with a high power in the upper rpm range. In addition to this, the turbine housing is divided into two flow passages which run parallel to one another.

Together with the likewise divided ducts in the exhaust manifold, this makes it possible to feed the exhaust flow to the turbine separately. The aim is to prevent the individual cylinders from influencing each other negatively during load cycles, and to improve the gas cycle. The result is higher torque at lower engine speeds, and extremely good responsiveness.

Furthermore, the shafts of the compressor and turbine have roller bearings for the first time ‑ as in the top output variant of the AMG 4.0-litre V8 engine in the AMG GT 4-door Coupé. The roller bearings reduce mechanical friction within the turbocharger to a minimum. The charger therefore responds more readily and reaches its maximum speed of up to 169,000 rpm more rapidly.

Charge pressure: electronically controlled for optimum responsiveness

With a maximum charge pressure of 2.1 bar, the 2.0-litre four-cylinder turbo engine is also the leader in its segment in this respect. The electronically controlled wastegate (exhaust relief valve) allows the charge pressure to be controlled even more precisely and flexibly while optimising responsiveness, especially when accelerating from partial load. Numerous parameters are taken into account in this process. The main input signals for the wastegate control unit are the charge pressure, throttle flap position and the knocking tendency. The modifying signals include the intake air temperature, engine temperature, engine speed and atmospheric pressure. This also makes temporary boosting of the charge pressure (overboost) possible under acceleration.

Fresh air is used in addition to oil and water to cool the turbocharger. This is directed specifically to the charger from the radiator grille, via the engine cover designed as an air deflector and ducts beneath the bonnet. The concept is based on the principles and experience gained with the cooling for the internally mounted turbochargers of the current AMG 4.0-litre V8 engines, starting with the AMG GT in 2014. In addition the turbine housing has integral insulation.

Crankcase: all-aluminium with outstanding properties

The all-aluminium crankcase is a chill-cast unit which excels with outstanding material properties. In this process the molten aluminium is poured into the metallic mould using the effect of gravity.

Thanks to its good thermal conductivity, the water-cooled mould allows rapid cooling and solidification of the melt. The result is a fine-grained, dense structure that guarantees very high strength. Complex interior geometries can be realised with the help of enclosed sand cores.

The so-called closed-deck construction – a design taken from motorsport ‑ ensures maximum rigidity with low weight and allows peak combustion pressures of up to 160 bar. The areas around the cylinders are mostly solid, and the cover plate is only penetrated by smaller ducts for the coolant and engine oil. The crank assembly with a lightweight, forged steel crankshaft and forged aluminium pistons with optimised piston rings combines low friction with high strength. The maximum engine speed is 7200 rpm, and peak output is developed at 6750 rpm. The sump features baffle plates so that despite the larger sump, and even under high lateral acceleration forces, there is always sufficient engine oil to lubricate all the relevant components.

Cylinder liners: coated with NANOSLIDE

To reduce friction between the pistons and cylinders, the linings are coated using patented NANOSLIDE technology. This gives the linings a mirror-like surface for minimal friction, is twice as hard as conventional grey cast-iron liners and therefore makes them much more durable. NANOSLIDE was developed by Daimler AG, and is protected by more than 90 patent families and more than 40 patents. This coating was first used in AMG's M 156 V8 engine, has enhanced other AMG engines for many years and can also be found in the Formula 1 engine of Mercedes AMG Petronas Motorsport.

Exhaust valves: larger dimensions for faster gas cycles

In the cylinder head, the repositioned and slightly angled injection nozzles and spark plug system have allowed much larger exhaust valves than in the preceding engine. The larger exhaust cross-sections allow the gases to stream out of the combustion chambers with low losses, and reduce the overall piston venting action.

Two overhead camshafts control the 16 valves via weight-optimised roller cam followers. Camshaft adjustment on the inlet and outlet side allows an excellent response and optimises the gas cycle for each operating point.

Variable CAMTRONIC valve control on the exhaust side is another feature, with two cams per valve. The cams have different geometries, so that depending on the cam setting to suit the driving situation, the exhaust valves can be opened for short or long periods – for even better responsiveness at low engine speeds, comfortable and fuel-efficient driving at medium rpm and full power delivery in the upper rpm range.

Petrol injection: two stages for optimised power

Turbocharging and direct injection with a spray guided combustion process not only allow a high power yield, but also improve thermodynamic efficiency and therefore reduce both fuel consumption and exhaust emissions.

For the first time, the new high-performance four-cylinder has two-stage fuel injection. In the first stage the particularly fast and precisely operating piezo injectors supply fuel to the combustion chambers at a pressure of up to 200 bar. This is a multiple process at times, and is controlled by the engine management system as required.

In the second stage there is additional intake manifold injection using solenoid valves. This is needed to achieve the engine''s high specific output. The electronically controlled fuel supply has an operating pressure of 6.7 bar.

Cooling: sophisticated system for the engine, turbocharger and charge air
 

The high output requires an intelligently conceived cooling system. This is so designed that the cylinder head and crankcase can be cooled to different temperature levels. This innovative measure allows a cold cylinder head for maximum output with efficient ignition timing, and a warm crankcase to reduce in-engine friction.

The coolant to the cylinder head is supplied by a mechanical high-performance water pump, while cooling of the crankcase is via a second, electrically driven water pump. After a cold start, this pump remains passive until the engine has warmed up. In operation it is regulated by the engine control unit so that the crankcase is always cooled according to need.

Moreover, the pump can be switched on or off as required when less output is needed, or at low engine speeds. Furthermore, the electric water pump ensures the full engine output and optimum heat dissipation over the entire engine speed range. It also protects against thermal damage when idling in very high ambient temperatures.

In addition the engine has an oil temperature management function which controls the warm-up phase and flexibly regulates the engine oil temperature. This brings the engine to its operating temperature more rapidly, reducing friction and wear. This is accompanied by the environmentally friendly ancillary effect that fuel consumption and cold start emissions are also reduced.

The engine's high degree of supercharging calls for a high-performance intercooler. So that the charge air can be cooled close to the ambient temperature despite the extreme quantities of heat, for the first time a 2-stage, indirect intercooler has been developed. It works in conjunction with the air conditioning system, and is used in the S-models where it has been integrated into the low-temperature circuit. For this was necessary to completely redesign the configuration of the condenser in the front end. One condenser is located in the wheel arch, and a second one is positioned in first row of the central cooling module. The separate condenser and radiator configuration and thermal management specifically designed to meet (everyday) requirements and (racetrack) performance enable efficient and coordinated cooling performance.

Functions such as alternator management, the ECO start/stop function with fast restarting, the gliding function and a petrol particulate filter are also part of the technology package for the new AMG four-cylinder.

Digital and smart hand assembly: "One man, one engine"

The new engine is entirely assembled by hand. To this end a completely newly designed production line was constructed in the AMG engine manufactory in Affalterbach, where Mercedes-AMG has raised the "One Man, One Engine" principle and Industry 4.0 processes to an innovative level reflecting the latest findings in ergonomics, material flows, quality assurance, sustainability and efficiency. On the road to implementing Industry 4.0, AMG's hand assembly operation likewise follows the vision of "smart production".

This excels with maximum flexibility, and is transparent and highly efficient. It safeguards and improves the quality of the engines and production processes using innovative and digital technologies.

AMG SPEEDSHIFT DCT 8G dual-clutch transmission: agile and responsive

The 8-speed AMG SPEEDSHIFT DCT 8G dual-clutch transmission likewise contributes to the agile and dynamic character. The gear ratios have been configured so that the driver experiences very spontaneous acceleration in all speed ranges, combined with fast shifting and optimum connections when shifting up. Depending on the selected AMG DYNAMIC SELECT driving mode, the driver receives a specific drive configuration with different accelerator and gearshift characteristics.

Anyone who prefers to change gear for themselves can select the manual transmission mode in every drive program. Using the temporary M-mode, this is possible very rapidly merely by operating a steering wheel shift paddle.

The standard RACE-START function allows maximum acceleration from stationary, a highly emotional experience. This also applies to the drive sound with partial ignition interruption when changing up a gear, and the automatic double-declutching function when changing down. Neither is efficiency neglected: in "Comfort" mode the ECO start/stop function is active; the "gliding" function can be selected in the "Individual" driving mode.

AMG Performance 4MATIC+ all-wheel drive with AMG TORQUE CONTROL
 

The extremely dynamic driving experience in a completely new dimension is greatly assisted by the fully variable all-wheel drive included as standard. The secret is AMG TORQUE CONTROL in the new rear axle differential: This has two electronically controlled multidisc clutches, each of which is connected to a rear axle drive shaft. In this way the drive power can not only be completely variably distributed between the front and rear wheels, but also selectively between the left and right rear wheel. This means that depending on the driving mode and situation, the drive torque can be separately distributed to both rear wheels.

The result is consistently optimum traction, even in adverse road conditions and during extreme cornering manoeuvres, for example on the racetrack. Furthermore, this sophisticated solution allows Drift mode (standard in the S-models, included in the optional AMG DYNAMIC PLUS package for the basic models), which makes "powersliding" possible for even more driving pleasure.

Drift mode can be called up in the "RACE" driving mode using the shift paddles, provided that ESP^® is deactivated and the transmission is in manual mode.

Electro-mechanical control: fast response irrespective of engine speed

Control of the drive torque to the front and rear axle, and between the two rear wheels, is electro-mechanical. The influencing factors for torque distribution are not only the driving speed, the lateral and longitudinal acceleration and the steering angle, but also the difference in rotational speed between the individual wheels, the gear selected and the accelerator position.

The main advantages of electro-mechanical control over an electro-hydraulic system relate to more refined driving dynamics – primarily due to the significantly faster response and speed-independent actuation of the discs over the entire adjustment range.

The all-wheel drive control is dependent on the selected driving mode and the AMG DYNAMICS setting. In "Basic" and "Advanced", the 4MATIC system is in "Comfort" mode. In "Pro" and "Master" (standard for S-models, included in the optional AMG DYNAMIC PLUS package for basic models) the 4MATIC system switches to "Sport" mode ‑ for even more agile handling and an even higher threshold for the critical limits.

Before the system intervenes, 3-stage ESP^® with individual control strategies in SPORT HANDLING MODE allows greater drift angles for a sporty driving style. When entering bends, the "45" models have an even more agile response thanks to braking intervention at the inner rear wheel ‑ depending on the selected AMG DYNAMICS mode or driving mode

Suspension: specific components for highly dynamic handling

The new AMG suspension with specific spring elements and the new,  frequency-selective shock absorbers provides the basis for high directional stability and highly dynamic cornering characteristics with low body roll. At the same time comfort has been improved compared to the preceding model. The longitudinal and transverse dynamics are perfectly coordinated.

All suspension components have been thoroughly revised in order to achieve a higher maximum lateral acceleration together with easy vehicle control at the limits.

A McPherson strut design is used at the front axle. Suspension is taken care of by one wishbone below the wheel centre, one spring strut and one tie rod respectively. The special axle geometry reduces the influence of the drive on the steering – for high comfort and agile handling. The new wishbone in aluminium reduces the unsprung masses enabling a more sensitive response from the springs. The brake callipers at the front axle are radially bolted – a technology from motorsport for more stability. The front axle carrier is rigidly attached and thus additionally stiffens the front section.

The 4-link rear suspension is likewise rigidly connected to the body via a rear axle carrier, and therefore very torsionally rigid. There are three transverse control arms and one trailing arm plus specific bearings per rear wheel. This design ensures maximum driving stability and agility.

AMG RIDE CONTROL adaptively adjustable damping: with three modes

The optional AMG RIDE CONTROL adaptive damping system enables the driver to choose between three different suspension control modes. The spectrum ranges from comfort-focused to sporty. The system operates fully automatically, adapting the damping forces for each wheel according to the driving situation and road conditions. This happens within milliseconds and is infinitely variable, with a wide spread of damping characteristics. The result is that it ride comfort and agility are enhanced in equal measure.

High-performance braking system: fade-resistant and reliable

The high-performance braking system ensures fade-resistant deceleration and short braking distances. In the basic models, the 4-piston monobloc fixed front callipers act on 350 x 34 millimetre brake discs, while at the rear axle, 1-piston floating callipers act on 330 x 22 millimetre brake discs. The discs are internally ventilated and perforated to better dissipate heat and prevent brake fading, even with extreme use. The grey-painted brake callipers have white AMG lettering.

The S-models and the basic models with the optional AMG DYNAMIC PLUS package are decelerated by an even larger braking system equipped with 6-piston fixed callipers and 360 x 36 millimetre brake discs at the front. In this case the brake callipers are painted red and bear a black AMG logo.

Steering: with special steering rack and variable ratio

The speed-sensitive, electro-mechanical sports power steering supports a sporty driving style with its direct turn-in ability. It has a special rack with variable transmission ratio and two characteristic curves: depending on which drive program the driver has selected, it provides taut and sporty or more comfort-biased steering feedback. The rigid mounting in the integral carrier connects the steering even better with the body and thus increases steering precision.

AMG exhaust system: with exhaust flap for sound modulation

As standard the exhaust system has an exhaust flap which is automatically controlled depending on the engine speed and load. Depending on the drive program selected it modulates the sound from harmoniously discreet (in the programs Slippery, Comfort and Sport) to emotively sporty (in Sport+).

Six driving modes: vehicle characteristics with wide spread
 

The six AMG DYNAMIC SELECT driving modes "Slippery", "Comfort", "Sport", "Sport +", "Individual" and "RACE" (standard for S-models, included in the optional AMG DYNAMIC PLUS package for basic models) allow a wide spread of vehicle characteristics, from comfortable to dynamic.

 Numerous relevant parameters are modified:

• Powertrain: accelerator characteristics, shift times and timing, sound characteristics with the options of Reduced, Moderate, Sport or Dynamic
• Transmission: automatic or manual
• AMG DYNAMICS: Agility functions such as all-wheel control, steering characteristics and additional ESP^® functions in Basic, Advanced, Pro or Master versions (standard for S-models, included in the optional AMG DYNAMIC PLUS package for basic models)
• Exhaust system: Sound and nature of the sound functions, Balanced or Powerful
• Chassis (with optional AMG RIDE CONTROL suspension): in Comfort, Sport, Sport+

The individual drive programs offer an individual driving experience, precisely tailored to different driving conditions and driver requirements.

• "Slippery": Optimum adaptation to suit slippery and icy road surface conditions, with reduced power requirement and flat torque curve. Smooth gear changes and earlier upshifting support the driving impression characterised by stability.
• "Comfort": comfortable and fuel-efficient driving, e.g. thanks to very early upshifts. Suspension and steering are set up for an emphasis on comfort. In addition, the ECO start/stop function is active here.
• "Sport": sporty characteristics thanks to a more agile response to the driver's accelerator pedal input, shorter shift times, earlier downshifts and significantly more emotive gearshifts owing to double de-clutching. A more dynamic suspension and steering set-up.
• "Sport+": extremely sporty characteristics thanks to an even more agile throttle response, increased acoustic emphasis on double de-clutching during downshifts as well as selective torque control on upshifts with cylinder suppression for optimal shift times. Increased idle speed for faster pulling away. An even more dynamic set-up for suspension, steering and drivetrain.
• "RACE": For highly dynamic driving on enclosed racetracks. In this program, all of the parameters are configured for maximum performance.
• "Individual": Makes it possible to select and store individual parameters according to personal preferences. In addition, the gliding function is available in the "Reduced" and "Moderate" drive settings.

AMG DYNAMICS: more agility with high stability

As a feature of the AMG DYNAMIC SELECT driving modes, the new 45 models have AMG DYNAMICS. This integrated vehicle dynamics control extends the stabilising functions of ESP^® with agility-enhancing intervention in the all-wheel control, steering characteristics and additional ESP^® functions. When cornering at speed, for example, brief braking intervention at the inner rear wheel generates a defined yawing motion around the vertical axis for responsive and precise entry into the bend.

The spectrum ranges from extremely stable to highly dynamic. On the multimedia display, when a drive program is selected, the new AMG DYNAMICS symbol is displayed together with the corresponding additional information.

• "Basic" is assigned to the "Slippery" and "Comfort" drive programs. In this case the compact sportscars exhibit very stable handling with a high level of yaw damping.
• "Advanced" is activated in the "Sport" program. The 45 models remain neutrally balanced. The lower yaw damping, lower steering angle requirement and enhanced agility support dynamic manoeuvres such as driving on winding country roads.
• "Pro" (short for "Professional") belongs to the "Sport+" program. In "Pro" the driver receives even more assistance for dynamic driving manoeuvres while agility and feedback from the road when cornering are further enhanced.
• "Master" is linked to the "RACE" driving mode (standard for S-models, included in the optional AMG DYNAMIC PLUS package for basic models). "Master" mode is aimed at drivers who want to experience dynamism and the driving enjoyment on closed-off circuits. "Master" offers a vehicle balance with slight oversteer, a low steering angle requirement and more agile steering. In this way, "Master" ensures maximum agility and fully exploits the dynamic potential. To activate "Master" mode, the driver must use the separate button in the centre console to switch the ESP^® to ESP^® SPORT Handling Mode or ESP^®

In the "Individual" drive program, the driver can set the AMG DYNAMICS levels "Basic", "Advanced", "Pro" and "Master" themselves.

Interior: close symbiosis between man and machine 

With its sporty appointments and the MBUX infotainment system, the high-quality interior creates a close, personal connection between man and machine. The driver and front passenger are seated in an active position on contoured sport seats with firm lateral support. The standard upholstery as a combination of black ARTICO man-made leather and DINAMICA microfibre is timeless, and creates typical AMG highlights with double topstitching in red. The colour scheme is echoed by the red designo seat belts and the dashboard support trim in black DINAMICA microfibre with a red border. The chromed air vents are likewise upgraded with a red ring. As an alternative an upholstery in ARTICO man-made leather in neva grey/black with mid-grey double topstitching and light-longitudinal-grain aluminium trim is available.

S-models: yellow highlights to emphasised the motor racing heritage

The A 45 S and CLA 45 S even go a step further: yellow highlights reoccur throughout the interior to emphasise the motor racing character of the more powerful models. Also included in the standard equipment are the AMG Performance steering wheel in nappa leather/DINAMICA microfibre with contrasting yellow topstitching, a yellow 12 o'clock marking, AMG steering wheel buttons and AMG logo, plus ambience lighting.

In all models, the centre console in high-gloss black with a touchpad as standard has a further control array with additional switches controlling the 3-stage ESP^®, the manual transmission mode and the optional adaptive damping system AMG RIDE CONTROL. In combination with the optional leather package, it features a silver chrome console surround.

The characteristic, sporty AMG ambience is also enhanced by the sports pedal cluster of brushed stainless steel with rubber studs, black floor mats with AMG lettering and a surround in a nubuck leather look, the black fabric roof liner and AMG front entry sills in brushed stainless steel with "AMG" lettering.

MBUX infotainment system: with AMG-specific displays

The combination of sporty design and sophisticated details is also featured in the MBUX infotainment system with its innovative operating and display concept. MBUX creates an even closer connection between the vehicle, driver and passengers. Emotionally appealing presentations underline the clear control structure and feature brilliant maximum-resolution 3D graphics. Visually, the two displays under one shared glass cover blend into a Widescreen Cockpit and as a central element consequently emphasise the horizontal orientation of the interior design.

The customer can choose between the three AMG display styles "Classic", "Sport" and "Supersport" for the instrument cluster. The "Supersport" mode is particularly striking with a central, round rev counter and additional information presented in the form of bars to the left and right of the rev counter: with a three-dimensional perspective, they reach far into the background to an artificial horizon.

Via the AMG menu the driver can call up various special displays:

• Gear display ‑ with yellow "M" symbol in manual mode
• Warm-Up menu ‑ engine and transmission oil temperature
• Set-Up menu ‑ AMG DYNAMIC SELECT settings
• G-Meter – longitudinal and lateral acceleration forces
• Race-Timer – stopwatch, lap and sector times
• Engine data – output and torque, engine oil and transmission oil temperature

The touchscreen multimedia display also emphasises the dynamic character with individual AMG displays such as visualisation of the driving programs, AMG TRACK PACE and telemetry data.

And needless to say, the trailblazing voice control activated with the words "Hey Mercedes" is also on-board. Thanks to artificial intelligence, MBUX recognises and understands nearly all sentences from the fields of infotainment and vehicle operation, even if they are expressed indirectly.

AMG Performance steering wheel: with optional control buttons

A perfect symbiosis between the driver and vehicle is ensured by the multifunction sport steering wheel in nappa leather with flattened steering wheel rim and perforated grip area, and depending on the upholstery, red, yellow or black topstitching and a facing in silver chrome. The galvanised steering wheel gearshift paddles allow an even sportier driving style with manual gear shifting.

The active distance assistant DISTRONIC and the TEMPOMAT cruise control can be adjusted on the control panels on the left. The control panels on the right are used to activate the voice control and telephone, and to regulate the sound volume, music selection and other functions of the infotainment system.

As standard the S-models are equipped with the AMG Performance steering wheel in nappa leather/DINAMICA microfibre (optional for basic model).

The AMG steering wheel buttons (standard for S-models, optional for the basic variants in conjunction with the Performance steering wheel) allow the AMG driving modes to be accessed directly, and other AMG functions to be conveniently operated directly at the steering wheel.

Individual optional equipment: even more intensive driver involvement

Numerous options are available to suit the new 45 models to individual customer wishes. They include the following

• Leather package and AMG leather package with 2-tone upholstery, for example classic red / black, plus instrument panel in ARTICO man-made leather
• AMG Performance steering wheel in nappa leather
• AMG Performance steering wheel in nappa leather / DINAMICA microfibre (standard for S-models)
• AMG Performance steering wheel in DINAMICA microfibre incl. AMG steering wheel buttons
• Door sills in brushed stainless steel with "AMG" lettering, illuminated
• AMG Performance Seat Package
• AMG Performance Seat package Advanced
• AMG Performance Seat package High-End
• AMG DYNAMIC PLUS package for the basic variants, with AMG RIDE CONTROL suspension, larger AMG high-performance braking system with red-painted 6-piston fixed callipers and 360 x 36 mm brake discs at the front, AMG steering wheel buttons, "RACE" driving mode and Drift mode

AMG TRACK PACE: Data logger for use on the race track

AMG TRACK PACE, the virtual race engineer, is standard equipment for the S-models, and otherwise optionally available in conjunction with HDD navigation and the media display: The software is part of the MBUX infotainment system, and when negotiating a race circuit it continuously monitors more than 80 vehicle-specific data (e.g. speed, acceleration). On top of this, lap and sector times are displayed, as well as the respective difference from a reference time. Because specific display elements are shown in green or red, the driver is able to see at a glance without reading numbers whether they are currently faster or slower than the best time.

After putting in some fast laps, the driver can use the data to analyse and, if necessary, improve their driving skills. In addition, acceleration and deceleration values (e.g. 0-100 km/h, ¼ mile, 100-0 km/h) can be measured and saved. Thanks to a newly developed algorithm which determines the vehicle position as precisely as possible, AMG TRACK PACE even detects when the circuit has been left or it has been shortened. This is done using GPS data as well as the sensors available in the vehicle (acceleration, gyroscope, steering angle, wheel speeds).

The data are displayed on the multimedia display, in the instrument cluster and on the optional head-up display. Well-known race tracks like, for example, the Nürburgring or Spa Francorchamps, are already stored. Furthermore, it is also possible to record your own circuits. The map display can be switched from 2D to 3D and updated online.

The MBUX Augmented Reality function also allows the ideal line of a stored race track to be displayed on the multimedia display or optional head-up display, allowing the driver to improve lap times with a virtual instructor on board.

Anche a me non sembra male, certo ha bisogno dei ruotoni per non apparire sproporzionata, ma d'altro canto questo vale per tutte le auto moderne.

Questa e' ancora di piu' una piccola CLS, bello il frontale e in generale mi piace piu' della Classe A corrispondente.

[Gengis26]

Rispetto alla vecchia è un passo in avanti! Inorridisco davanti all'arancione usato per interni e ruote... ma nel complesso è meglio della precedente!

[GL91]

Ooh, sono contento che abbiano scelto un abbinamento di colori sobrio finalmente (sarcasmo, l'arancione fuori è tamarrissimo).

 

A parte questo, davanti non è male affatto, mi piacciono molto i fari, decisamente meglio di quelli della Classe A, mi convincono meno il muso basso e i rigonfiamenti sul cofano. Mi preoccupa il fatto che non ci siano foto del posteriore, da quel poco che si vede pare simile alla CLS, e non è un buon segno.

scusate ma si parla di crisi delle berline e MB rinnova questa banana?

mi chiedo... la precedente ha venduto bene? altrimenti non trovo motivo per riproporre una MB a TA e tre volumi, a meno che in Cina non sbavano per questi aborti

Ma con già la Classe A berlina questa a cosa serve?

 

L’altra la venderanno in primis alle flotte, questa ai privati con chissà che delta di prezzo.

 

Mi piace il frontale, ma il resto dell’auto lo trovo sproporzionato, soprattutto se lo si confronta con l’auto a cui si ispira.
