HOT on the heels of the launch of the updated Audi RS 4 Avant, its sister Coupe and Sportback models have also been given a significant make-over.

The RS 5 and RS 5 Sportback benefit from the latest Audi exterior design tweaks and upgraded cabin configuration already adopted by the RS 4, with MMI touch technology based around a large central screen.

The latest models come in three trim levels - RS 5, RS 5 Carbon Black and RS 5 Vorsprung - and dealers will open the order books early in the new year with prices starting from £69,500.

Enhancements to the exterior include a wider and flatter front grille with larger, contoured air inlets either side. Matrix LED headlights are standard across the board while the range-topping Vorsprung version features laser lights with darkened bezels.The wheel arches have been widened by 40mm and the side sills have been redesigned, as has the rear diffuser.

Nappa leather sports seats are fitted as standard to all UK versions, as is Audi's virtual cockpit with a 12.3-inch display which enables the driver to toggle between multiple screens, one of which is RS-specific. The head-up display, which is a standard feature of Vorsprung versions, also offers exclusive RS graphics.

In addition to its primary infotainment functions the large, free-standing display provides the driver with information on engine temperature, longitudinal and lateral acceleration, the quattro sport differential operating status, tyre pressures and tyre temperatures.

As before, power comes from a 444bhp, 2.9 litre twin-turbo V6 petrol engine mated to a quick-shifting eight-speed Tiptronic transmission which now comes with larger aluminium shift paddles. Both RS 5 models accelerate from zero to 60mph in less than 3.9 seconds and can reach an electronically limited top speed of 155mph - in Vorsprung versions this is increased to 174mph.

Audi's legendary quattro permanent all-wheel drive comes with a standard sport differential on the rear axle to maximise its potential by distributing torque actively between the rear wheels.RS 5 and RS 5 Carbon Black models are fitted as standard with sport suspension while the flagship Vorsprung model also comes with dynamic ride control.
