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. At 7,800 rpm the 4.2-liter engine delivers 420 bhp of power output. Peak torque is 317 lb-ft 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 60 mph in 4.4 seconds and reaches a top speed of 187 mph.
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.
