The new Audi RS6 also makes its international debut in Detroit. Lighter, more powerful and more efficient than its forebear, the RS6 develops 552bhp from its twin-turbo V8 and will crack 0-100kph in a supercar-rivalling 3.9 seconds.
The performance car showcase continues with the R8 V10 Plus. Sitting at the top of the R8 range, the Plus features revised suspension geometry and standard carbon-ceramic brakes for greater track performance.
