* Sprint to 100 km/h in 3.9 seconds, top speed 316 km/h
* High-performance sports car with striking design
The V10 engine in the production sports car will be almost identical in construction to the one in the racing version. Its displacement is 5,204 cc, at 6,500 rpm it delivers 530 Nm (390.91 lb-ft) of torque, at 8,000 rpm its power tops out at 386 kW (525 hp).
The specific power output is 100.9 hp per liter of displacement - and each hp has to propel only 3.09 kilograms (6.91 lb) of weight, because the Audi R8 V10 in the version with the six-speed manual gearshift weighs only 1,620 kilograms (3571 lb). The engine accounts for 258 of these kilograms (569 lb) - that's only 31 kilos (68 lb) more than the V8.more
