Audi has introduced revised versions of its sporty models RS6 and RS, packing more power and a range of exterior changes.

Called the Performance, Audi has boosted the 4.0-litre twin-turbo V8 engine by 30bhp and 50Nm of torque, with the models now producing 621bhp and 850Nm of torque.

The changes have come from fitting larger turbochargers and an increase in boost pressure in the engine, with the RS6 Avant and RS7 Sportback now able to accelerate from 0-60mph in 3.2 seconds – two tenths quicker than before.

The updated models gain a number of exterior tweaks

Design changes to separate the Performance models apart from the regular RS6 and RS7 include lightweight 22-inch alloy wheels, along with new Continental tyres that promise better grip in both wet and dry conditions, as well as improved braking distances. New matt grey styling elements have been introduced too, along with two new colours – matt Ascari Blue and matt Dew Silver.

Customers can also choose an optional ‘RS Dynamics Package’, including a raised top speed to 189mph, and ceramic brakes that save 34kg off the weight off the RS models compared to the standard steel brakes.

The new RS6 Performance and RS7 Performance are priced from £112,650 and £116,305 respectively.
