Look what we have here: an Audi RS6 Avant test mule during cold weather testing. Great find!
With more aggressive front fascia (spotted on some earlier test mules) a wider track and add-on fender flares, there’s no doubting that this is a preproduction prototype of the RS 6 Avant. Big ceramic brakes underneath A8 wheels only seem to further confirm the car’s RS status.
It is expected that the RS 6 will use the same 4.0 TFSI biturbo V8 as the S6, S8 and even the new Bentley Continental GT V8. Power levels remain to be seen, but iterations of the 4.0 TFSI in the S8 and the Bentley are 500+.
