Audi has released the first official details and photographs of its fastest ever road car: the limited-edition RS6 Plus.
Designed as a send-off for the outgoing A6 range, the new model arrives in June only in Avant estate bodystyle, priced at £66,675 – nearly seven grand more than the standard car.
An extra 30bhp is extracted from the RS6’s twin-turbo 4.2-litre V8 by replacing the ECU and adding two extra radiators behind the intercoolers, taking power up to 480bhp. Maximum torque of 413lb ft is available all the way from 1950 to 6000rpm.
As befits the most powerful road-going Audi ever, the RS6 Plus is also the fastest. Ingolstadt claims 0-62mph in 4.6sec and zero to twice that velocity in a scant 17.3sec.
Other mechanical changes over the standard RS6 include ventilated brake discs and a sports exhaust. Dynamic Ride Control suspension is carried over, reducing rolling and pitching movements, while buyers can pick firmer, 10mm lower sports suspension at no cost.
The standard RS6 was already a pretty good Q car – and the Plus model continues that theme. The only changes are matt black exhaust tailpipe finishers and roof rails, aluminium pedals and a numbered plaque on the centre console. Fewer than 1000 will be built.
