When the 580 bhp Audi RS6 Avant was revealed, the premium manufacturer was announcing its intentions to come out at the top of the German horsepower wars.

Now the sedan variant of the RS6 has now been caught once again testing in Germany by our spies with the most revealing shots yet. The front fascia in unchanged from the avant model but we can see the rear styling mimics that of the A4. Power will come from the Avant's V10 which will give impressive performance figures of 0-100km/h in 4.6 secons.
