Power for Audi R8 Abt is set to come from a supercharged version of Audi's 4.2-liter V8 engine delivering a claimed 530 hp — some 110 hp more than the standard Audi R8. That's sufficient, according to the German tuner, to provide the Porsche 911 Turbo chasing two seater with 0-to-62-mph acceleration in 3.8 seconds and a top speed of 197 mph.
