New RS5 offers the full Audi RS experience - including a torque-varying Quattro all-wheel drive system.

Audi has unveiled the facelifted RS5 Coupe in Frankfurt.

The RS5 Coupe comes a little longer (23 mm/0.91 inches) and wider (6 mm/0.24 inches) than a standard A5 Coupe and sits 6 mm lower too.

Under the bonnet is the same high-revving, normally aspirated V8 as before. The 4.2 FSI has an output of 331 kW (450 PS / 444 hp), at 8,250 rpm, and peak torque of 430 Nm (317.15 lb-ft) available between 4,000 and 6,000 rpm. Transmission is the Seven-speed S tronic.

The RS5 Coupe does the 0 to 100 km/h (62.14 mph) sprint in 4.6 seconds and has an electronically-limited top speed of 250 km/h (155 mph), which Audi will bump up to 280 km/h (174 mph) on request.

The Quattro all-wheel-drive system has the ability to vary the torque distribution between the front and rear axles and has a default setting of a rear-biased 40:60 ratio.

Both the front and rear suspensions are made of aluminum on the RS5 Coupe and Audi offers an optional DRC dynamic ride control system with variable damping.

The RS5 comes with three drive modes - Comfort, Auto and Dynamic and the interior offers special touches such as the RS menu on the driver info system replete with a lap timer and an oil temperature guage.
