The raison d’Ãªtre of a concept car is to explore new ideas and to test the ideas in an attempt to create the ultimate solution. Know-how and passion, combined with imagination, then become the motive force that turns the dream into reality. A dream that can be shared through the creation of a unique vehicle such as the Peugeot 908 RC.
The 908 RC owes its name to its engine: the Peugeot V12 HDi DPFS, which will power the racing version of the 908 in 2007. The abbreviation «RC», used to designate sports models in the Peugeot range, also refers to the RC♠ and RC♦ concept cars which made their appearance in 2002 and whose architecture served as an inspiration during the design of this innovative project.
The original idea was to create a limousine with an imposing style that offered its four occupants a new driving sensation. The fi nal design, however, is an uncompromising car that combines dynamic performance, comfort, luxury and environmental protection. In short, it is an exclusive four-door vehicle that will capture the imagination of both occupants and onlookers.
Engine and architecture
The 908 RC is powered by Peugeot’s V12 HDi DPFS (diesel particulate fi lter system) diesel engine designed to take part in the “Le Mans Race Series” programme in 2007. The engine has a capacity of 5.5 litres and offers a level of performance unprecedented for a diesel engine, with a maximum power output greater than 515 kW and, above all, an exceptional torque in excess of 1,200 Nm. With a 100° V angle architecture, the engine’s centre of gravity is as low as possible. Two particulate fi lters are located at the end of each exhaust system ensuring the car’s environmentally-friendly credentials.
The originality of the 908 RC resides in its compact design, with the engine arranged in a rear central transverse position. Similarly the compact 6-speed electronically controlled sequential gearbox, has been specially adapted to withstand the phenomenal torque, and is located under the engine.
The position of the power train allows the creation of a large-capacity boot, situated behind the fi nal drive assembly and therefore not encroaching on the generous interior space of the passenger compartment. This design also allows the driving position to be moved forward, maximising the driving experience for both the driver and the passengers.
The design of the 908 RC creates a particularly low-lying exterior body with a stylish tapered design at the front of the vehicle. Its proportions create an elegant and dynamic statement. Sitting on large diameter 20 spoke alloy wheels (20’’ at the front, 21’’ at the rear); the overall effect is that of a big cat, from the nose at the front, to the tip of the rear lights. More than ever, the Marque’s emblem has played a part in fashioning the power of expression of the 908 RC.
At the front, the lion’s character seems to emanate from each detail, starting with the design of the headlights. Lighting is provided by light-emitting diodes (LEDs), with their dazzling appearance the result of a special fi nish given to the internal components. The exterior appearance of the lights looks like a crystal cut like a precious stone, creating a faint outline like the pupil of an eye. The bonnet draws its inspiration directly from the head of a big cat.
The areas either side of the bonnet create the effect of the cat’s “cheeks” with the bonnet tapering down to a nose, highlighted by the large chromed emblem of the Marque. A lot of attention has been paid to the design of the exterior body, with its lack of door handles creating surfaces of great simplicity and purity, and highlighting to maximum effect the refl ections that accentuate every facet of the body.
Aligned with the curves of the car’s pronounced “hindquarters”, the rear lights, equipped with LEDs, incorporate a polished aluminium insert evoking the shape of a powerful claw. The dynamic rear profi le is characterised by the shape of the rear air diffuser, accentuated by chrome detailing and supported visually on each side by twin exhaust pipes.
The metallic black body colour with its bluish refl ections further enhances the impression of status, dynamism and purity portrayed by this car. Inside the 908 RC The ambience inside the 908 RC is the result of meticulous attention to detail on the part of the car’s designers.
Thanks to a forward-positioned passenger compartment made possible by the car’s architecture, and a large glazed surface area of 3 m2, occupants are truly at one with the road and the passing landscape. The special shape of the huge front windscreen allows a completely unimpeded fi eld of vision (as on the RC concept cars). The front windscreen stretches back behind the driver’s head, as far as the B/C post where the glazed roof begins. This gives both front and rear passengers a sense of being at one with the outside environment. Unequalled brightness and visibility combine with a generous interior space, complete with four independent seats, helping to create a truly exceptional ambience.
The light and fl owing style of the interior, combined with the latest technology ensures purity of the design and a comfortable interior. For example, all vehicle functions (radio, MP3 player, satellite navigation, four-zone air conditioning, etc) can be easily controlled by means of a large touch screen, the Man/Machine Interface (MMI). The MMI is also accessible by the rear passengers, thanks to a multimedia screen positioned on the centre console separating the two rear seats. The high-quality materials and interior fi nish of the 908 RC creates an atmosphere that is both luxurious and timeless. The passenger compartment features dark oak surrounds, integral amethyst-grey leather trim, polished aluminium inserts, touches of chrome, and a Bell&Ross clock: everything stimulates the senses of touch, sight and smell. Practical aspects have not been overlooked either. Numerous storage spaces, in addition to the large air conditioned glove box, are located in the door panels and also in the front and rear consoles.
Structure and Suspension
In the great tradition of Peugeot concept cars, the 908 RC is a unique model conceived in the inner sanctum of the Peugeot Design Centre. The vehicle is built around a pre-impregnated carbon composite and vacuum-polymerised aluminium honeycomb structure. The rear section is a self-supporting shell incorporating a sub-frame consisting of a tubular structure on which the engine and suspension are assembled.
Both at the front and the rear, the car features a drop link, double wishbone type suspension, derived from the 407. Braking is by means of four monobloc ceramic carbon composite discs which reduce weight and improved thermal effi ciency. The wheels are fi tted with Michelin Pilot Sport PS2 255/35 R20 tyres at the front and 285/30 R21 at the rear.
The car’s aerodynamics has been particularly fi ne-tuned to attain an excellent drag coeffi cient of only 0.556. The air ducts were designed in a wind tunnel to optimise the car’s performance and fuel consumption, while ensuring the necessary cooling of the power train.
A two-part front air intake directs air to cool both of the engine’s radiators and also improve the car’s aerodynamic performance by controlling the internal and external fl ow by means of the black anodised aluminium vents located upstream of the front wheels. Air is provided to the engine by means of vents located in the rear quarter panels.
Air is also directed from the rear wheel arches, through the two intercoolers for the turbochargers and then out through the visible vents behind the wheel arch. A controllable rear spoiler incorporated into the boot lid can be raised at the request of the driver to improve road holding.
The fl at under fl oor and diffuser enhance further the aerodynamic effi ciency of the 908 RC. Finally, the 908 RC, is a luxurious touring interpretation of the racing car of the future, through its engineering it creates the spirit of the «gentleman driver», It is targeted at a very upmarket virtual customer, naturally accustomed to a very high level of luxury but above all passionate about their motoring and its history, but also in search of innovation coupled with assertive styling and uncompromised driving pleasure.
