Audi RS 3 Sportback e RS 3 Sedan 2021

[Cole_90]

Il 2.5 TFSI dell'Audi RS3 mantiene la potenza di 400 CV disponibili già a 5.600 giri, mentre la coppia è aumentata di 20 Nm per un totale di 500 e ciò si traduce in una spinta immediata anche ai bassi regimi. Di base la velocità è sempre limitata a 250 km/h, ma aggiungendo il pacchetto RS Dynamic si sbloccano tutte le potenzialità del cinque cilindri. La RS 3 è la prima Audi equipaggiata con l’RS Torque Splitter. Questo rimpiazza il differenziale posteriore e il precedente sistema multidisco con una nuova componente elettronica che assicura un’ottimale distribuzione della coppia sul retrotreno. Durante le fasi di guida sportiva, viene inviata più coppia alla ruota posteriore più esterna per migliorare l’agilità e ridurre il sottosterzo. Il sistema consente di eseguire anche dei drift: scegliendo la modalità RS Torque Rear, la centralina invia fino a 1.750 Nm su una sola ruota creando il sovrasterzo e avviando, di fatto, la derapata. Un’altra novità è l’unità di controllo mVDC che raccoglie i dati dal ripartitore di coppia, dalle sospensioni adattive e dal sistema di trazione integrale per adattare l’agilità dell’auto.

“A quantum leap for agile driving” – that’s what racing and development driver Frank Stippler had to say about the torque splitter with its fully variable torque distribution on the rear axle. Audi will soon launch the first-ever series roll-out of this technology in a sporty compact-class RS model. Frank Stippler and Meic Diessner, development and test engineer for chassis, spoke in an interview about the development and tuning process for the torque splitter in the RS 3 prototype. Both worked together throughout the entire development in various testing and set-up cycles on the North Loop of the Nürburgring to ensure that the new technology meets the wishes of sporty drivers on the racetrack as well as customers looking for comfort in day-to-day driving. That also included two self-contained continual runs of 8,000 kilometers each.

 

Mr. Diessner, Mr. Stippler, what was the process for you to work together on the development and tuning of the RS torque splitter?

Meic Diessner: Frank is incredibly important to us in this process. He has a lot of experience, especially on the Nürburgring. That makes feedback from him decisive for the tuning and especially for the torque splitter. I’m there on site for the tests and I also drive myself as part of the three-week continual run. I equip the vehicle with measuring technology and compare the data with the feedback we get from Frank so that we can make changes if needed.

Frank Stippler: In addition to my experience and my ability to drive cars fast, my training as an automobile mechanic and my degree in mechanical engineering also help, of course. This allows me to make sense of the feedback from the car immediately so I can pass it on to Meic. At the same time, he understands what I mean when I’m talking about the feedback the car is giving me on the track.

What’s more important: the measurement data or the feedback from the development driver?

Meic Diessner: The data and the impressions from Frank are used equally in tuning the torque splitter. The feedback from a racing driver is very important because he is at the upper limits out on the racetrack. The measurement technology helps me to change certain parameters based on Frank’s descriptions. The one does not work without the other.

What does the torque splitter feel like in the RS 3 prototype? And why was it put in?

Frank Stippler: In general, the car is much more agile in its driving from the middle of the curve to the end and also when accelerating out of the curve. All-wheel drive cars have great tracking stability, but they tend to understeer at the very upper limits. We were looking for a solution that would minimize that behavior. The torque splitter distributes more weight onto the rear axle. With it, the car develops a driving dynamic that oversteers. And that’s where the Audi drive select system comes in, which helps meter that tendency based on use, road conditions and individual preferences. We can get really fast in RS Performance mode, the mode for circuit driving that is designed especially for semi-slick tires. For me, the RS torque splitter is a quantum leap in terms of agile driving.

How exactly did Frank Stippler’s findings flow into the tuning?

Meic Diessner: That is of course mostly during the two continual runs of 8,000 kilometers each on the Nürburgring. These extended test runs play an important role during development in practicability – and thus also the serial roll-out of the torque splitter.

Which parameters can still be changed during these tests?

Meic Diessner: In general, the software gets more and more complex during development. This has to be adapted for the available driving modes – from auto to RS Torque Rear, which allows controlled drifting on closed circuits. In practice, that means Frank drives, gives us feedback. We adjust and take turns driving – until it’s just right.

When is it determined to have reached series-production readiness?

Frank Stippler: You develop a sense for that over time. I bring in my opinion, because I’m at the absolute upper limit with the car and have an idea of what customers want from this car. When Meic and I are on the same page after test drives, then that reinforces an overall picture that we have made of the characteristics of the torque splitter. And that has to be consistent for everyone involved in the development. The North Loop testing grounds are especially important in this process. The RS 3 prototype covers a broad spectrum that appeals to sporty drivers. Customers who don’t drive on the racetrack or only do so seldomly are also taken into consideration.

How intelligent is the torque splitter?

Meic Diessner: It recognizes, for example, if the road is wet or dry. So the driver doesn’t have to change the mode. That means that the car automatically reacts differently in RS Performance mode it the road is wet than it would when it is dry. The driver also benefits from the variability of the RS torque splitter all the way to the top speed. So they always have quattro drive when it is needed.

Why is it important in the vehicle tuning not just to be fast?

Frank Stippler: Because we want to understand how the hardware and electronics work together in any possible driving situation. In short, to have an eye on the overall technical image of the vehicle. It’s not about me or about tuning the car to be as fast as possible on the racetrack. To live up to the wishes of customers in terms of dynamics and driving comfort, it probably helps that I don’t just drive fast in a loop, but that I can also classify technical correlations.

What can Audi fans look forward to?

Frank Stippler: A car that covers a broad spectrum:comfortable in city driving and top speeds on the racetrack. A car that is one-of-a-kind in its class and makes hearts beat a little faster.

Meic Diessner: We’re talking about a well-made car with a five-cylinder motor and a great sound that will certainly give you goosebumps. On top of that, a sporty, balanced chassis with the torque splitter, which gives the car lots of variations in combination with the driving modes and that elevates the driving dynamic to a higher level.

The new Audi RS 3: unmatched sportiness suitable for everyday use

• 400 PS, five-cylinder engine with 500 newton meters of torque
• RS Torque Splitter and new RS 3 driving modes for even more agility
• Expressive exterior design and interior racing atmosphere

From 0 to 100 km/h in 3.8 seconds, up to 290 km/h top speed, RS Torque Splitter, semi slicks, and specific RS driving modes – the new Audi RS 3 offers driving dynamics of the highest caliber and the best numbers in its segment. Equipped with a 294 kW (400 PS) five-cylinder, the high-performance engine delivers rapid acceleration with a highly intoxicating sound. The power unit now delivers 500 Nm of torque and responds even faster. Visually, the RS 3

demonstrates its sporty DNA with a widened body, RS sports exhaust system, and cockpit displays like those found in race cars.

 

“With the third generation of the Audi RS 3 Sportback

and the second generation of the Audi RS 3 Sedan

, we now offer premium sports cars that are suitable for everyday use and equally thrilling to drive on public roads and racetracks,” says Sebastian Grams, Managing Director of Audi Sport GmbH. “They represent the entry point into our RS world and, thanks to the torque splitter, the ultimate in outstanding performance in the compact segment.”

Unmatched acceleration and top speed: the 2.5 TFSI

With its five-cylinder, high-performance engine, the Audi RS 3

is one-of-a-kind in the segment. The 2.5 TFSI has won the “International Engine of the Year” award nine times in a row. In the latest generation of the compact sports car, the engine is now more powerful than ever before. The new RS 3 models sprint from zero to 100 km/h in just 3.8 seconds. Their top speed is limited to 250 km/h, but 280 km/h is also available as an optional upgrade. With the RS Dynamic package and ceramic brakes, they can even reach a top speed of 290 km/h. This makes the Audi RS 3 the best in its class in terms of acceleration and top speed. This is primarily due to the 500 Nm increase in torque, which is available between 2,250 and 5,600 rpm. That is equal to 20 Nm more than its predecessor. As a result, the Audi RS 3

accelerates even faster from low rev ranges.

The engine's maximum power of 294 kW (400 PS) is available earlier than before at 5,600 rpm and extends over a broad plateau to 7,000 rpm. A new engine control unit also increases the speed at which all of the drive components communicate with each other.

A seven-speed dual-clutch transmission is what puts the power of the five-cylinder engine to the pavement – with short shifting times and a sportier gear ratio spread. The engine’s unique 1‑2‑4‑5-3 ignition sequence and the incomparable sound that comes with it make the driving experience that much more exhilarating. For the first time, the exhaust system features a fully variable flap control system that supports intermediate positions, thus broadening the sound characteristics even further. It can be adjusted via the driving dynamics system Audi drive select. In the Dynamic and RS Performance modes, for example, the flaps open much earlier – the emotional elements of the sound are even more pronounced. In addition, the unmistakable sound of the five-cylinder engine is further enhanced by the optional RS sports exhaust system.

Maximum agility: RS Torque Splitter and specific RS 3 modes

The new Audi RS 3

is the first Audi model that comes standard-equipped with a torque splitter. It replaces the rear axle differential and the previous multiple disc clutch package on the rear axle. Instead, an electronically controlled multiple disc clutch is used on each of the drive shafts. This ensures that the right amount of torque is optimally distributed along the rear axle. During more dynamic driving, the torque splitter increases the drive torque to the outer rear wheel with the higher wheel load, which significantly reduces the tendency to understeer. In left-hand curves, it transmits the drive torque to the right rear wheel, in right-hand curves to the left rear wheel, and when driving straight ahead to both wheels.

The new technology also makes controlled drifts on closed-off tracks possible – in this case, the torque splitter directs all of the power to only one of the rear wheels, with up to 1,750 newton meters per wheel possible. Audi even developed a driving mode specifically for the RS 3

for this purpose – “RS Torque Rear” – as a drift mode with its own characteristic curve for the torque splitter. The RS Performance mode, created specifically for the racetrack, is another never-before-seen innovation. It uses a specific engine and transmission configuration and is precisely tailored to the semi-slick tires that are, for the very first time, available for the RS 3

as a factory option. In this case, the torque splitter delivers a particularly dynamic, sporty ride along the longitudinal axis with as little understeer and oversteer as possible. These modes can be selected via the Audi drive select driving dynamics system, which also offers the following profiles: comfort, auto, dynamic, RS Individual, and efficiency.

More dynamic ride with greater precision: RS sports suspension and larger wheel camber

The standard RS sports suspension features newly developed shock absorbers and a valve system both specific to the RS 3

. The valves ensure that the shock absorbers exhibit a particularly sensitive response as part of the rebound and compression characteristics. This allows the suspension to respond to the respective driving situation even faster and more effectively. The RS sport suspension plus with adaptive damper control is available as an option. It continuously and individually adjusts each shock absorber to the road conditions, the driving situation, and the mode selected in Audi drive select. The three characteristic curves comfortable, balanced, and sporty provide a clearly perceptible spread of the shock absorber characteristics.

The larger wheel camber, i.e. the wheels are angled more toward the road, results in a more precise steering response and increased cornering force. Compared to the Audi A3, the wheels on the front axle of the new RS 3

have just under one degree of additional negative camber. To achieve this, the pivot bearings were modified and the lower wishbones were equipped with stiffer bearings, subframes, and stabilizers. A rear axle features a four-link design with separate spring/damper arrangement, subframe, and tubular stabilizer bar. The wheel carriers, which are stiffer than those of the Audi A3 and S3, absorb the increased lateral forces generated by the torque splitter. The negative wheel camber here is almost half a degree more compared to the A3. The RS‑specific progressive steering varies the gear ratio depending on the steering angle – as the steering angle increases, the gear ratio becomes smaller and steering more direct. It also assists based on speed and can be varied via Audi drive select. The setup of the springs and shock absorbers is markedly stiff, and the body is ten millimeters lower than on the S3

and 25 millimeters lower than on the A3.

Another new addition to the RS 3

is the modular vehicle dynamics controller (mVDC). This central system captures data from all the components relevant to lateral dynamics, thus ensuring that they interact more precisely and more quickly. The mVDC synchronizes the torque splitter, adaptive dampers, and wheel-selective torque control for precise steering and handling. All in all, it increases the vehicle’s agility, especially on winding roads.

Powerful deceleration: six-piston steel and ceramic brake system

The RS 3

comes standard-equipped with larger and newly developed six-piston steel brakes to keep the power of the five-cylinder engine in check. A ceramic brake system measuring 380 by 38 mm is optionally available on the front axle with a pedal characteristic curve specially adapted to the brake booster. The high-performance brake system weighs another ten kilograms less than the steel brake. Its internally ventilated and drilled discs measure 375 by 36 mm at the front and 310 by 22 mm at the rear. This makes them larger and more stable than in the previous model. Air control elements improve the brakes’ cooling time by 20 percent. This more quickly reduces peak temperatures during hard braking while pedal feel remains the same. In addition, it also reduces brake pad wear, which are 15 percent larger and copper-free. Those who opt for the ceramic brakes can choose between gray, red, or blue brake calipers. Those who prefer the steel version can order red calipers instead of the black ones.

Expressive and unmistakable: exterior and lighting

The design of the new Audi RS 3

is even more dynamic and powerful than that of its predecessor. In the front, the wide RS bumper, the redesigned Singleframe with its distinctive honeycomb grille, and the large air intakes give the compact sports car an expressive appearance. The RS 3 comes standard-equipped with flat, wedge-shaped LED headlights and LED taillights including dynamic turn signal lights. Matrix LED headlights are available as an option, with darkened bezels that feature digital daytime running lights around their outer downturned angles. With its pixel field of 3 x 5 LED segments, it provides an unmistakable look – a checkered flag appears in the left headlight as a dynamic leaving and coming home scene, and the RS 3

lettering appears on the driver’s side. When driving, the checkered flag lights up on both sides.

There is also a new design element behind the front wheel arches: an eye-catching additional air outlet. The rocker panels with black trim have also been redesigned and, in combination with the flared wheel arches, contribute to the expressive look of the new RS 3

. The front axle track has been widened by 33 millimeters compared to the previous model. On the Sportback, the rear axle track has increased by ten millimeters. The RS 3

is standard-equipped with 19-inch cast wheels in a 10-Y spoke design. True racing design is embodied by the optionally available 5‑Y spokes with RS branding. Audi will also mount Pirelli P Zero “Trofeo R” performance semi-slick tires for the first time, if desired. The motorsports-inspired finishing touches include the redesigned RS-specific rear bumper with integrated diffuser and the RS exhaust system with two large oval tailpipes.

The new Audi RS 3

models can be ordered in two exclusive RS colors: Kyalami green and Kemora gray. The roof of the Sedan can also be ordered in the contrasting color Brilliant black for the first time. Individual exterior features, such as the honeycomb grille in the Singleframe, come standard in black – either in a matte or high-gloss finish. The Alu-Optic Trim package is available as an option and accentuates the front bumper, diffuser insert, and window trim. For an even sportier look, the rocker panel inlays are also available in carbon-fiber-reinforced polymer. The same applies to the mirror caps, the tailgate spoiler on the Sedan and the roof edge spoiler on the Sportback.

Genuine racing feeling: the interior

In the interior, too, many elements specific to the RS accentuate its sportiness. The displays appear in the 12.3-inch Audi virtual cockpit plus, which comes standard. It displays the rpms in the form of a bar graph and shows power and torque as percentages. Optionally, the rpm display is available in the new “RS Runway” design. In this case, the values are displayed in the opposite direction in a manner that visually resembles an airplane runway – the highest speed in the foreground and the lowest speed in the background. In addition, the Audi virtual cockpit plus includes displays for g‑forces, lap times and acceleration from 0‑100 km/h, 0-200 km/h, quarter mile, and eighth of a mile.

The RS-specific blinking shift indicator in manual transmission mode changes the rpm display from green to yellow to red, blinking in a manner identical to that used in motorsports, to indicate the ideal time to change gears. The 10.1-inch touch display includes what is referred to as the “RS Monitor,” which displays the coolant, engine, and transmission oil temperatures as well as tire pressures. Also available for the first time for the Audi RS 3

is a head-up display that projects relevant information onto the windshield in the driver's direct line of sight in addition to the shift light indicator.

The genuine racing feeling is further enhanced by the carbon-fiber instrument panel and RS sport seats with RS embossing and anthracite contrast stitching. The seat upholstery is optionally available in fine Nappa leather with RS honeycomb stitching and glossy black, red, or, for the first time, green contrast stitching. RS Design packages in red and green are available to match. They include special floor mats with contrast stitching and RS embroidery, as well as seatbelts with colored edges. The Design package plus includes seat corners in red or green and a colored accents on the air vents.

Everything under control: steering wheel with 12 o’clock stripe and RS Mode button

The RS 3

is standard-equipped with a three‑spoke RS Sport multifunctional leather steering wheel with a flattened bottom. It features built-in, high-quality die-cast zinc shift paddles. Those who opt for the Design package get, in addition to the RS badge, a 12 o’clock stripe for faster indication of the steering wheel position during dynamic driving. Alternatively, a round RS steering wheel is available with hands-on detection, i.e. capacitive grip recognition, for assisted steering functions. Both have the new RS Mode button on the right-hand steering wheel spoke in common. This button can be used to select the Audi drive select modes RS Performance, RS Individual, or the last mode used. In both RS modes, the display of the instruments and the head‑up display has an even sportier look with a blinking shift indicator.

Availability: market launch and pricing

The Audi RS 3 Sportback

and RS 3 Sedan will be available to order in Europe starting in mid‑July 2021. The new RS 3 models will be launched in the fall of this year. The base price for the RS 3 Sportback is set at 60,000 euros, while the RS 3 Sedan is listed at 62,000 euros.

Press Release Torque Splitter:

 

 

Cita

The Audi RS 3 prototype represents the epitome of unadulterated driving dynamics. This is Audi’s first vehicle to feature the RS Torque Splitter, which distributes drive torque between the rear wheels in a fully variable manner. This results in optimal stability and maximum agility – especially when cornering at high speeds.

 

How does the RS Torque Splitter work?

The RS Torque Splitter makes active, fully variable torque vectoring between the rear wheels possible. Unlike the rear axle differential and the previous multiple disc clutch package on the rear axle, the torque splitter uses one electronically controlled multiple disc clutch each on the respective drive shaft. During dynamic driving, the torque splitter increases the drive torque to the outer rear wheel with the higher wheel load, which significantly reduces the tendency to understeer. In left-hand curves, it transmits the torque to the right rear wheel, in right-hand curves to the left rear wheel, and when driving straight ahead to both wheels. This results in optimal stability and maximum agility – especially when cornering at high speeds. When driving on closed roads, the torque splitter enables controlled drifts by applying all of the engine power at the rear axle to just one of the rear wheels – up to a maximum of 1,750 newton meters of torque. The exact distribution of drive torque always depends on the mode selected in Audi drive select and the respective driving situation.

Each of the two multiple disc clutches has its own control unit, which use the electronic stabilization control’s wheel speed sensors to measure the wheel speeds. Other influencing factors include longitudinal and lateral acceleration, the steering angle, the position of the gas pedal, the selected gear, and the yaw angle, i.e. the rotational movement around the vertical axis. In addition, the torque splitter is connected to the modular vehicle dynamics controller as a higher-level entity.

Why does the torque splitter improve driving performance?

Due to the difference in propulsive forces, the car turns into the curve even better and follows the steering angle more precisely. This results in less understeer, earlier and faster acceleration when exiting corners, and particularly precise and agile handling – for added safety in everyday use and faster lap times on the racetrack. The torque splitter also compensates for oversteer by directing the torque to the wheel on the inside of the curve or, if necessary, to both wheels.

How is the torque splitter integrated into the driving dynamics system?

Audi drive select modifies the characteristics of the torque splitter and thus the car’s handling depending on the selected mode. Five characteristic curves – Comfort/Efficiency, Auto, Dynamic, RS Performance, and RS Torque Rear – are saved in the system. In this context, engine power is distributed to all four wheels in the Comfort/Efficiency modes, with priority given to the front axle. In Auto mode, torque distribution is balanced, which means that the RS 3 prototype neither understeers nor oversteers. Dynamic mode, on the other hand, tends to transmit as much drive torque as possible to the rear axle – for maximum agility and increased dynamics. This is taken to perfection in RS Torque Rear mode, which allows drivers to perform controlled drifts on closed roads. The highly rear-heavy distribution of the engine power leads to oversteering behavior, with up to 100 percent of the drive torque directed to the rear ending up at the wheel on the outside of the curve. In addition, Audi has adjusted the engine and transmission characteristics. This specific setup is also used by RS Performance Mode, which is designed for the racetrack. It is specially tuned to the Pirelli P Zero “Trofeo R” performance semi-slick tires. In this mode, the torque splitter delivers a particularly dynamic, sporty ride along the longitudinal axis with as little understeer and oversteer as possible. This results in fast acceleration out of corners and thus better lap times.

What role does the modular vehicle dynamics controller play?

The modular vehicle dynamics controller (mVDC) ensures that the chassis systems interact more precisely and more quickly. To do so, this central system captures data from all the components relevant to lateral dynamics. The mVDC synchronizes the torque splitter’s two control units, the adaptive dampers, and the wheel-selective torque control for high-precision steering and handling. All in all, it increases the agility of the entire vehicle, especially on dynamic stretches of road.

Com’è fatto il sistema. L’RS Torque Splitter utilizza due frizioni multidisco a controllo elettronico, una per ciascun semiasse posteriore. Durante la guida sportiva, il sistema incrementa la coppia in uscita verso la posteriore esterna, riducendo significativamente i fenomeni di sottosterzo e incrementando al contempo stabilità e agilità. L’RS Torque Splitter rende possibile anche una vera e propria funzione di drifting, inviando tutta la potenza del motore a una sola delle ruote posteriori.

Come funziona. A variare momento per momento la distribuzione della coppia sono due unità di controllo, una per ciascuna frizione multidisco, che usa i sensori di velocità delle ruote che fanno capo all’Esp per intervenire, regolando la ripartizione sulla base di parametri come modalità di guida selezionata, accelerazioni frontale e laterale, angolo di sterzo, marcia inserita, posizione dell’acceleratore e angolo d’imbardata.

Gran bella macchina, i cosiddetti pops & crackles non sono affatto invasivi e niente, davvero gran macchina a prescindere dal drift mode. 

 

Anche se da un video mi pare che abbia un sound dall'abitacolo un pò artificiale, ma non troppo...

 

[adm2000]

Scusate, ma ho capito bene che questo sistema indirizza il 100% della trazione che arriva al posteriore solo su una delle due ruote (l'esterna), che non significa assolutamente che all'occorrenza può diventare 100% posteriore (come ho già letto su alcuni siti...)

[VuOtto]

 

beh.....l'OPF purtroppo leva molto della timbrica che la faceva assomigliare quasi ad una Gallardo...... ma resta il fatto che è la Hot Hatch più speciale che sarà commercializzata. Magari qunado aziende come akrapovic o supersprint faranno un impianto di scarico (o parti di esso) più spinte, sarà facile ritrovare il sound delle vecchie generazioni.
