Press Release :

208 HYbrid FE, when PEUGEOT and Total combine driving pleasure and efficiencyAt the Frankfurt Motor Show, PEUGEOT and Total will unveil their technological concept, the 208 HYbrid FE, a full petrol hybrid with exceptional characteristics and without a Plug-in energy source. The Research and Development teams the two partners rose brilliantly to the challenge proposed by establishing a remarkable level of performance, based on a production PEUGEOT 208 hatchback: 0 to 100km/h / 0 to 62mph in 8.0 seconds and CO2 of just 49g/km over the official NEDC European Drive Cycle (Combined Cycle figure). Numerous innovations are implemented in several areas:

- Aerodynamic properties: improvements of 25% for the CdA,

- Weight: reduction of 20%,

- Powertrain: 10% improvement in fuel economy,

- Hybridisation: recovery of 25% of the energy over one drive cycle.

The 208 HYbrid FE project combines ideas which until now acted against each other - Fuel Economy and Fun&Efficient, reason and driving pleasure - giving a preview of the vehicles of tomorrow. “The 208 HYbrid FE project is essential as it explores solutions for reaching the bar of 2l/100km. It also showcases our R&D work with our historic partner Total. Together, we are developing more economical vehicles, we are winning victories all over the world. Together, we are making good progress.” Maxime Picat, Director General, Automobiles Peugeot “With the 208 HYbrid FE, PEUGEOT and Total are combining their expertise to offer the technical solutions of tomorrow. Energy efficiency is a strategic aspect for our Group as it is at the heart of the expectations of our customers, who wish to enjoy the benefits of efficiency and yet retain driving pleasure. It is also a response to contemporary environmental challenges and the means of preserving fossil fuels, which are precious resources.” Philippe Boisseau, member of the Executive Committee, President of Marketing & Services and New Energies department at Total

Since 1995, PEUGEOT and Total have been working extensively together to significantly increase fuel economy, improve CO2 emissions and the TCO (Total Cost of Ownership) of motor vehicles. For PEUGEOT, this is a long-standing environmental policy. With this commitment, in 2013 the Marque is reducing still further the weighted average emissions of CO2 of its European ranges: by the end of May it was 116.3g/km, compared to 121.5g/km in 2012. Total’s researchers are continually working on developing future motor vehicle fuels and lubricants. The Group provides PEUGEOT and its networks worldwide with FE (Fuel Economy) lubricants: by reducing friction in the combustion engine, these lubricants have contributed to a 5% reduction in

CO2 emissions in the last ten years with PEUGEOT engines. The Total Excellium top-of-the-range fuels also contribute to improving fuel economy. The objective of the 208 HYbrid FE is to combine real driving pleasure with low CO2 emissions. More

precisely, the intention is to halve the CO2 emissions of the PEUGEOT 208, equipped with the 1.0- litre VTi 68 and to provide it with acceleration comparable to a performance hatchback, so quite a challenge! The challenge is made all the greater for the teams of the 208 HYbrid FE project as the production PEUGEOT 208 is already renowned for its weight-saving design and its latest-generation engines that allow it to offer a high-level driving experience. To rise to this challenge, Total and PEUGEOT therefore combined their capacity for innovation in all areas capitalising on the virtuous circle initiated by the hatchback. “The goal of 49g and acceleration from rest in 8.0 seconds is as difficult to achieve as victory on the other side of the world. The small team consisting of the best experts in each of the areas brought all of its creativity and enthusiasm into play, and we did it!” Bruno Famin, Director, PEUGEOT Sport The 208 HYbrid FE, all part of the Marque’s hybrid strategy

The policy goal in terms of CO2 is ambitious. It involves achieving 95g/km on weighted average of the new vehicles sold in Europe in 2020. To rise to this challenge without sacrificing driving pleasure, PEUGEOT is investing in several technologies which are already present on its vehicles and achieving substantial progress: continuous improvement of the efficiency of the internal combustion engines, down-sizing strategy, widespread use of the Stop & Start, electric drive ... The HYbrid4 diesel-electric hybridisation, is part of this process. Launched as a world first by PEUGEOT on the 3008 Crossover, it has since been extended to the 508 RXH and the 508 Saloon.

Over 28,000 customers of the HYbrid4 technology have discovered an new driving pleasure which combines performance, simplicity of use, silent-driving and reducing environmental impact with CO2 emissions from 88g/km.3 With the 2008 HYbrid Air, PEUGEOT is innovating once more in the interests of the environment and of its customers in all of its markets. In fact, this breakthrough technology combines petrol and compressed air to fulfil customer expectations and rise to the challenges facing the motor industry. On the current generation of B segment vehicles, the HYbrid Air considerably improves fuel economy and reduces CO2 emissions. In fact, on completion of the homologated Drive Cycle tests, the figures are set at just 2.9l/100km (97.4mpg) and 69g/km. This technology is a key step towards the goal of reducing fuel consumption to just 2.0l/100km (141.2mpg). The 208 HYbrid FE combines innovations which will make it possible to achieve this record figure. PEUGEOT style, naturally efficient Fluidity is part of the Marque’s stylistic heritage, it is in its DNA. On the 208 HYbrid FE, the aerodynamics experts took the exercise to an extreme. So, the Cd improves by 25%, to a value slightly lower than 0.25 and a real feat on a conventional vehicle where the passenger space and boot are maintained! To achieve this, the air is parted by the ‘floating grille’ redesigned for permeability and reduced by 40% to just 5dm². In fact, as the engine has been modified for efficiency, it duly requires less cooling. On the body sides, any flow disrupting components has been eliminated to help improve the aero performance. The tyres, specially developed by Michelin, are of the Tall&Narrow type, ie: of large diameter and narrow width. They are fitted on 19” alloy wheels on which the carbon aerodynamic flaps fill the space between each spoke.

Cameras provide the rear vision, the image being reproduced on board on the interior mirror reminiscent of sporting disciplines like endurance racing. The rear track also contributes to this efficiency by being narrower by 40mm, further reducing the Cd. Finally, the design of the roof extends in an almost horizontal movement leading into the tailgate spoiler. The rear aspect, with chamfered edges, has an air deflector in its lower section. It deflects the airflow which passes under the vehicle without hindrance due to the completely flat floor. Finally, to reduce its environmental footprint as much as possible, the LED lamps of the 208 HYbrid FE have thin vertical fins, inspired by the Onyx Concept supercar. These features minimise the air flow

turbulence.

A considerable reduction in weight: 20% When it was launched, the PEUGEOT 208 hatchback shook up the segment, notably due to its light weight - from only 975kg at the Access level. This performance is remarkable, but in the future

vehicles will need to be even lighter while still providing the high levels of comfort and safety. “Reducing the weight was a primary area of consideration. To achieve the 20% reduction in the weight of the vehicle we carried out a study part by part and equipped the 208 HYbrid FE with the most innovative materials from Hutchinson, CCP Composites and Total’s Polymers activity. This process is even more virtuous as it does not sacrifice any of the safety and comfort used in the vehicle while

introducing real innovations.” Philippe Girard, Scientific Department Representative, Total Composite materials The 208 HYbrid FE benefits from the latest material innovations developed by the Polymers Division of the Refining-Chemicals department at Total, as well as by its two subsidiaries CCP Composites and Hutchinson. Taken from the end of the assembly line, the 208 retains its metal structure. Composite components replace bodywork panels and the floor, further reducing the weight of the body shell from 295 to 227kg. The one-piece outer skin (weighing just 20kg), the flat base (8kg), the door panels (c2kg) and the lower front panel are made from carbon fibre. The bonnet (5kg) and the wings (c2.1kg) are constructed from a composite VER/Carbon, a material which is half the weight but with comparable structural properties. It is obtained from a new type of resin which can be used untreated, painted or colour-dyed. Finally, with the exception of the door windows, the glazing uses polycarbonate to further save 5kg. The 208 HYbrid FE innovates in its use as this material has up until now be reserved for headlight lenses. It reduces the weight by more than 50% compared to conventional glass. Innovative suspension and wheels

The 208 HYbrid FE rests on innovative pseudo MacPherson suspension with a ‘glass fibre resin’ composite transverse located blade. It replaces several components: suspension springs, lower wishbones and anti-roll bar. The front blade also has varying flexibility along its length. Designed and produced by Hutchinson, using these two blades saves 20kg. Due to their dimensions, the 145/65 R19 wheels themselves reduce the rolling resistance by 20%. They also require less effort on the steering wheel to direct them, making steering assistance superfluous: saving in space under the bonnet, fuel consumption and extra weight. The wheels are fitted onto low friction bearings assisted by special Total grease. The wheel rims house large brake discs 380mm in diameter and 9.6mm thick. They are rigged with two-piston callipers, 44.5mm at the front and 31.8mm at the rear.

On braking, the reduced effort on the pedal and the intervention of the electric motor mean that the supplementary braking assistance can be eliminated. A passenger compartment for five occupants The 208 HYbrid FE needed to retain the interior features of the production hatchback model. The result proves it: a very economical vehicle that can comfortably accommodate five people and their luggage. Only the air conditioning is eliminated due to its impact on fuel consumption. The composite door trim pads are developed by Total’s Polymers Division using Polypropylene reinforced with natural fibres. Its excellent structure, rigidity and impact absorption properties are accompanied by a reduction in weight of up to 15% and mean a reduction in the carbon footprint of these components. The centre console and vent trims are of VER resin (CCP Composites) left untreated to offer an appearance not previously seen before. In fact, their slightly amber honey colour reveals the natural fibres through transparency. The weight reduction techniques have also been applied to the petrol engine and the gearbox. An efficient and high-performance power train The 208 HYbrid FE is driven by a petrol-electric hybrid powertrain, which combines development of the latest generation of 3-cylinder engine with a battery and an electric motor taken from PEUGEOT Sport’s Endurance programme. Special engine management and special software control the entire drive train. Overall, the efficiency of the powertrain increases by an impressive 10%. “The challenge of this project consisted of combining engine optimisations (reciprocating gears, cylinder head, etc.) and optimising the flow of energy between the internal combustion engine and the

electric motor. All of the solutions can potentially be carried over to production.” Julien Lidsky, Manager, 208 HYbrid FE Powertrain, PEUGEOT Sport

1.2-litre VTi-FE petrol engine of high efficiency

The 3-cylinder engine has undergone several modifications: optimisation of the engine operational cycle, reduction of friction losses, thermomanagement... All of these advances lead to fuel economy improvements by 10% yet with power maintained at 68bhp (50kW). The Miller Cycle is accentuated and the compression ratio modified from 11:1 to 16:1 to increase the engine’s thermodynamic efficiency. This can lead to self-ignition of the mixture (or knock), which is potentially destructive. To prevent this, several actions were taken. So, the rate of unburned elements in the combustion chamber is reduced by valves of increased diameter, redesigned exhaust pipes, a redesigned manifold, and an adapted valve lift pattern. Furthermore, the heat exchanges are optimised in the cylinder block due to coolant passages arranged between the cylinders. The coolant now passes through the cylinder head along its entire length to recover the heat around each source: combustion chambers, between injectors and spark plugs.

The engine adopts direct injection which, by means of very precise phasing with the closing of the cylinder, maximises the benefit of each molecule of fuel. The variable setting at the inlet and at the exhaust extends the range of optimum efficiency to the entire engine speed range, both at full load and partial load. However, not all of these various developments favour power at high engine speed. So, the capacity is modified to 1,233cm3 by increasing the bore and the stroke (75mm x 93mm) to maintain the declared 68bhp (50kW). On the other hand, this progress benefits the maximum torque produced which increases by 25%. All of the moving components are specific to the 208 HYbrid FE. The nitrated steel crankshaft, the titanium con rods and the aluminium-copper alloy pistons are cut from solid. So, their weight is reduced in spite of the increase in capacity; the con rods and Gudgeon pins being halved. The friction losses are a challenge as they represent approximately 1/5th

of the power consumed by an engine. On the 208 HYbrid FE, they are reduced by approximately 40% notably by the crankshaft, the pistons and the Gudgeon pin, the piston rings and the camshaft followers. These components are given a diamond-like Carbon coating and are geometrically optimised. The weight of the cylinder head, also cut from a solid block, is halved due to the reduced thicknesses permitted by its design and the characteristics of the aluminium used. The coolant circuit and the

inlet line are made by rapid prototyping of resins charged with glass fibres or carbon. To do this, the laser beam of a 3D printer fuses successive layers of aluminium powder. This produces a functional component quickly and more cheaply in the context of individual specialised manufacture. Produced using the same process, the piston base jets serve here both to cool them on use under load and to heat the oil as quickly as possible on starting. This virtuous circle affects all of the areas explored by this technological demonstrator. So, the size of the radiator is reduced, benefiting the aerodynamic properties. The alternator, the starter and the reverse gear are eliminated, reducing the weight, mechanical losses, but also in its overall

dimensions.

Piloted transmission

The base of the production piloted manual gearbox is retained for its high efficiency and its integrated actuators. The casings cut from a solid block houses a cascade of gears to connect the electric engine to the differential crown wheel. To reduce friction losses, the teeth of the gears are given a tungsten carbide chrome coating. The greasing is redesigned to reduce the volume of lubricant necessary and prevent splashing over the gears, which also consumes energy. Now, the lubricant is moved to the highest point by the final drive crown wheel before circulating through gravity over the entire mechanism. The prototype gearbox oil is developed by Total Lubricants based on bio-sourced oils, of 75W grade with a very high viscosity index (higher than 250). This produces a 3% reduction in consumption, and becomes a preview of the lubricants of the future. Taken directly from a competition environment, a fluid grease of low density also reduces the quantity deemed necessary. Its longevity is assured by operation at a lower temperature due to a reduction in friction and finally, the hub bearings adopt a special fluid grease, which adheres but limits friction losses.

Fuel and lubricant

The 208 HYbrid FE passes the CO2 emissions cycle with a benchmark Super 95 fuel. The performance additives of the Excellium type, developed by Total Additives and Special Fuels, would alone reduce the CO2 emissions of this engine by more than one additional gramme per kilometre. “The 208 HYbrid FE offers a convergence of innovations from the laboratories of Total. Today, the group’s researchers are developing biofuels, energy saving lubricants (Fuel-Eco lubricants) and special

additives all contributing to improving fuel economy. In France, close to 250 researchers are working on developing the products of tomorrow.” Philippe Montantême, Senior Vice President Marketing and Research Strategy, Marketing & Services department at Total A special engine oil of extremely low viscosity has been developed by Total Lubricants using ultra-fluid based oils and by the addition of friction reducing agents containing molybdenum. Of grade 0W12, this oil develops its properties very rapidly with a shorter temperature rise time. Optimised as regards friction, it retains, both when hot and when cold, an advantage compared to the best products on the market. Thus improving fuel economy, here again a few more grammes are saved!

A hybridisation taken from endurance experience The project has benefited from the expertise of PEUGEOT Sport with its experience acquired in endurance competition. So, the electric motor and the battery are those developed for the PEUGEOT 908 HYbrid4 endurance race car. “The hybridisation developed for the 908 HYbrid4 is state-of-the-art in this domain. The work consisted of integrating it within the power train of the 208 to recover as much energy as possible on braking and using its full potential on acceleration.” Pierre Lebrene, Manager, 208 HYbrid FE Energy Recovery System, PEUGEOT Sport A special architecture The electric machine combines power and lightness as, at only 7kg, it develops 30kW as a motor and 100kW as a brake generator. In both modes, its torque reaches a maximum of 30Nm. Proportional to the speed of the vehicle, its maximum speed is 40,000rpm. This electric motor provides the reverse gear function, by inverting the direction of rotation, and the

starter function. It also provides access to ZEV driving, purely electric. The Lithium-ion battery, which has a capacity of two usable MJ or 0.56kWh, consists of 0.56 cells of 90V each. They are arranged in groups, which permits the ability to isolate one if deemed necessary. To ensure that this strategic unit is cooled correctly, Total has developed a special oil for circulating in the dedicated radiator. Weighing 25kg, it is installed, with the 20-litre petrol tank, on a subframe which is bolted underneath the vehicle directly below the rear bench seat. Here, sporting experience is demonstrated withi mproved weight distribution. For the inverter and the ECU, these are installed under the bonnet in the space left free by the braking assistance. The hybridisation has no effect on the interiorpackaging, so the inside the vehicle the passenger space is maintained.

The principle of operation

During deceleration phases, whether by releasing the accelerator pedal or through braking, the vehicle is slowed down primarily by the electric motor. The hydraulic braking only comes into operation at the end of braking phase to maximise the recovery of the energy available. Over one homologation cycle, this recovery is 25%. Then, on acceleration, this energy is returned and assists the petrol engine according to various parameters: acceleration dictated by the driver and the gear

selected.

The 208 HYbrid FE, Fun&Efficient and Fuel Efficiency

The PEUGEOT and Total teams, who have been working for months on creating this technological demonstrator, can be justifiably proud.Up until now, there have been low consumption vehicles and high performance vehicles. For the first time, these two qualities are combined in the same vehicle. The emissions of CO2 are just 49g/km. The different areas divide up the reduction of 50g/km as follows:

- weight reduction, aerodynamic properties and tyres: 40% that is 20g,

- hybridisation: 40% that is 20g,

- engine and gearbox: 20% that is 10g.

The performance aspect, which improves from 14 to 8 seconds over the 0 to 100km/h / 0-62mph exercise is also contributed to by:

- weight reduction, aerodynamic properties and tyres: 4 seconds,

- hybridisation: 2 seconds.

The 208 HYbrid FE proves itself beyond the figures. Due to the virtuous circle in which the two partners became involved, the driver enjoys new experiences at the wheel of this technological demonstrator: acceleration worthy of a GTi with mixed fuel economy of 2.1 1/100km (112mpg). Without any loss of comfort or ease of use, the driver will rediscover a direct link with the road due to the elimination of the powered, energy-consuming assistance. “At the beginning of the project, the objective seemed very ambitious, of a very high level. It was! The two partners, PEUGEOT and Total, achieved it by combining their technological expertise. PEUGEOT Sport has contributed its expertise to the project and has identified new areas of development.

Production and competition are progressing together.” Christophe Mary, Technical Manager of the 208 HYbrid FE project, PEUGEOT Sport The 208 HYbrid FE proves that the emotional aspect will always have its place in a PEUGEOT vehicle, even in an increasingly restrictive energy and environmental context.
