What is it?
Audi has a long, if not entirely illustrious, history of making estate cars fast enough to make your dog feel very queasy indeed. While the B7 RS4 Avant from a couple of generations ago was widely regarded as a high point for fast Audis, there have been far more misses than hits.
The RS6 Avant has long been the perfect example of how the German brand falls a little short of making a truly great performance car. While you can’t argue with the sheer amount of power on offer or the usability quattro brings, they’ve proved to be numb and often spine-shatteringly firm in the UK.
So what’s changed, then? Well, the RS6 Avant has received the Performance treatment that’s also available on the RS Q3. In the RS6, that ramps horsepower up from a potent 552bhp to a supercar-worrying 597bhp. Torque is normally 516Ib ft, but the Performance pack adds an overboost function that briefly increases this to 553Ib ft.
Furthermore, we’ve finally got our hands on a car running the standard air suspension set-up. Considering how uncomfortable the optional steel springs made things, the RS6 Avant could finally come good here.
