Unlike BMW that introduced the M3 Sedan only to replace it a few months later with a facelift version, Audi patiently waited to present the revised A6 range (see details here) before it unleashed the almighty RS6 Sedan. Like the new RS6 Avant that was unveiled at last year’s Frankfurt Motor Show, the RS6 Sedan packs a twin-turbocharged 5.0-liter V10 engine that delivers an output of 580 HP between 6,250 and 6,700 rpm and a peak torque of 650 Nm (479.42 lb-ft) available from 1,500 to 6,250 rpm.

Step inside and the first thing you’ll notice if you checked the correct box on the options list are the awesome driver and front passenger bucket seats seen in the pictures below. Otherwise you’ll have to be content with a set of deeply sculptured sport seats upholstered in Silk Nappa leather, with leather/Alcantara and Valcona leather available as option.
The Audi RS 6 will be launched on the market in mid-October with the starting price in
