The RS6 ditches the old Lamborghini-derived V10 for a version of the 4.0-litre twin-turbo V8 from the S6
This is the all-new 552bhp Audi RS6 super-estate, and it's the first of four RS models due in 2013
Audi has released official details of its new V8-powered 552bhp RS6 Avant – the first of four new RS models due on sale next year.
The others are the RS5 Cabriolet (which effectively replaces the RS6 saloon), the RS7 and the first ‘Q’ model to wear the RS badge – the Q3 RS.
