Audi‘s A6 range has been completed with the launch of the RS6 saloon, a twin-turbo V10-powered supercar-chaser.

The £76,160 saloon joins the Avant launched earlier this year to complete the RS range that tops the A6 line-up.

The RS6 can take the 0-62mph dash in 4.5 seconds, and fuel economy is quoted at an average 20.3mpg.

Deliveries begin in November.
