605hp Audi RS6 and RS7 performance editions revealed

Ever felt your 560hp Audi RS6 Avant or RS7 Sportback was just a bit down on power? Well, good news – Audi has announced two new ‘performance’ variants, shaving 0.2 seconds off their 0-62mph time.

That performance boost comes from an extra 45hp and 516lb ft of torque – increased to 553lb ft by way of an overboost function.

As a result, both the RS6 Avant and RS7 Sportback models can hit 62mph in 3.7 seconds and 124mph in 12.1 seconds – a 1.4-second advantage over the regular RS models. As standard, they’re both electronically limited to 155mph, but good for 174mph with the limiter removed – or 189mph if you spec the dynamic package plus.

At a time when Volkswagen Group is under a lot of pressure to be utterly transparent with regards to efficiency claims, Audi says the RS6 Avant performance returns 29.4mpg while the RS7 is capable of 29.7mpg in the official NEDC test. This is partly thanks to the manufacturer’s cylinder on demand system, which means only four of the 4.0-litre engine’s eight cylinders are activated under regular driving.

Externally, both RS6 and RS7 performance models sport 21-inch alloy wheels, wearing 285/30 (RS6 Avant) and 275/30 (RS7) tyres.

Revised bumpers with large air inlets, as well as flared sills and a black honeycomb grille complete the performance look.

The Audi RS6 Avant and RS7 performance models will be available to order in the UK from November, with deliveries starting from February. The Audi RS6 Avant will cost from £86,000 while the RS7 Sportback costs £91,600.
