The 5.2-liter powerplant uses direct injection according to the FSI principle developed by Audi. The Audi R8 V10 with R tronic gets by on an average of 13.7 liters per 100 km (17.17 US mpg). The Audi R8 V10 5.2 FSI quattro rockets from zero to 100 km/h (62.14 mph) in 3.9 seconds. In the version with the sequentially shifting R tronic it reaches 200 km/h (124.27 mph) in another 8.1 seconds. Even then its propulsive power hardly lessens: it's sufficient to reach a top speed of 316 km/h (196.35 mph). The immense force, the spontaneity and the thrust of the acceleration, plus the sound of the engine - all these impressions coalesce into a breathtaking sports car experience. The V10 plays a concert with growling bass tones and powerful high notes, which grows into a grandiose fortissimo as the engine revs up. This sonorous acceleration doesn't reach its limit until 8,700 rpm.
