Two ultra-responsive turbos will be added to the Lambo-derived 5.2-litre V10 from the S6, resulting in an eye-watering 530bhp.
The turbos will make sure that the RS6 isn’t short of twist. The smaller turbo will be tuned for low-revs response, while the bigger blower takes over at higher engine speeds for overtaking wallop. No definitive figures are out yet, but the V10 should be good for at least 500lb ft.
