The interior
The sporty interior is dominated by a totally driver-oriented cockpit architecture, integrating the driver between the dashboard and the high centre console. The instrument panel above the console is angled slightly towards the driver. The flat-bottomed steering wheel is a typical feature of the sportiest Audi models, and also enables comfortable sports car entry and exit.
Form follows function: this design principle is implemented throughout the Audi R8. Alongside the driver-oriented architecture, also reflected in the styling of the side window sills, the choice of materials also makes for a highly functional look and feel. Looking around when in the driving seat makes one thing clear: just like in the R8 race car, the styling and placement of all the elements in the cockpit of this driving machine is focussed on the essentials. The centrepoint of everything is the driver.
This combination of the aesthetic and the ergonomic is maintained in the colours used and the overall ambience created - dark hues reflect the emphasis on engineering and are again reminiscent of the motorsport world. The impression of professional functionality and ergonomic styling is enhanced by the visible presence of top-quality materials in supreme craftsmanship.
The sports seats are trimmed as standard in a Leather/Alcantara combination, or optionally in full leather. Alternatively, the R8 can also be fitted with bucket seats, specially developed by quattro GmbH. There is plenty of room for the two occupants, with comfort levels well beyond the norm of high-performance sports cars. There is space behind the seats to stow large bags, or even two golf bags. The luggage compartment at the front has a capacity of 100 litres.
With numerous trim variants and applications in Piano finish or Carbon sigma, there are few limits to the range of customisation options for the interior.
The drive train
Turbine-like power up to the highest rev ranges, a high maximum torque, all combined with a fascinating sound, are the characteristics of a perfect sports car engine. An engine that is fascinating both in terms of its enormous power potential and its suitability for everyday use.
In the high-revving 420 bhp eight-cylinder engine, the evolution of FSI petrol direct injection technology has reached a new high. This technology has also enjoyed many triumphs in the Audi R8 race car.
The figures illustrate the outstanding potential of the eight-cylinder unit. At7,800 rpm the 4.2-litre engine delivers 309 kW (420 bhp) of power output. Peak torque is 430 Newton-metres from 4.500 to 6,000 rpm. And no less than 90 per cent of this maximum torque is maintained consistently throughout a wide engine speed range from 3,500 all the way to 7,600 rpm. As a result of these qualities, the eight-cylinder power unit provides maximum thrust in virtually any driving situation.
The performance figures are equally impressive: the R8 accelerates from a standstill to 100 km/h in 4.6 seconds and reaches a top speed of 301 km/h.
The engine is a high-revving unit. The maximum engine speed is 8,250 rpm. The advantages of this principle are superior power output at high engine speeds and a smooth, eager responsiveness all across the revs range. Added to this are its agility, liveliness and engine sound, which is similar to that of a race car.
The Audi R8's dry sump lubrication - another technology originating directly from motor racing - provides the ideal basis for maximum longitudinal and lateral acceleration. It allows the V8 to be installed lower, thereby lowering the centre of gravity and further enhancing driving dynamics.
Two transmissions are available: a manual 6-speed gearbox or optionally the Audi R tronic sequential-shift gearbox. Here, too, the influence of the motorsport world is clearly evident, with a joystick gear-shift on the centre console and, most especially, the paddles mounted on the steering wheel, which are a long-established ergonomic feature in motorsport. The best illustration of this is once again the Le Mans winning Audi R8, which also enables the driver to change gear on the steering wheel.
'Shift by wire' technology provides for very fast gear-shifting and an outstanding power-to-weight ratio, allied to compact gearbox dimensions. The Sport mode, with its fast shifting, guarantees the absolute maximum in terms of driving fun. An automatic mode can also be selected.
Such a powerful Audi is of course fitted with permanent four-wheel drive, which distributes the power variably to the front and rear axles by way of a viscous clutch. On the Audi R8 the legendary quattro system is adapted to the axle load distribution typical of mid-engined cars.
