The revised vehicle will benefit from an exterior makeover which will see more aggressive styling techniques employed, including a redesigned front nose, new rear bumper and more angular side sills.

Designed as an "elegant coupe", the RS5 will combine blistering pace and powerful performance with a fuel-efficient engine to maintain the manufacturer's eco-friendly message.

It is claimed that the vehicle - named the F800 - will offer strong hints as to the look of the new CLS executive saloon which will be available to buy later this year.
