What is it?
This is the Audi RS6 saloon, the four-door version of Audi’s most powerful production car. Until now, the Audi RS6 has been available in Avant form only, but with the A6’s recent facelift comes a saloon version of the twin-turbo V10.
Losing a little glass and metalwork saves 50kg over the Avant, enough to nudge the RS6 below the two-tonne mark. While an improvement, this is still mighty heavy for a car with sporting pretensions.
What’s it like?
Like the Avant, the Audi RS6 saloon’s engine and transmission is nothing short of a sensation. Despite producing 572bhp, you couldn’t ask for a smoother delivery; with 480lb ft of torque available anywhere between 1500rpm and 6250rpm.
So the RS6 does mind-bendingly rapid very well indeed and, thanks to that hugely broad torque spread, it will do so with the merest twitch of your right foot. But the RS6 saloon is equally happy mooching around on part throttle, unlike the overly frenetic BMW M5.
However, if you arrive at a corner too fast there’s no hiding from that mass; the RS6 is occasionally hesitant to change direction. And yet its blend of epic performance and a decent smooth-shifting automatic gearbox is wonderful.
