Parkers overall rating: 4 out of 5 4.0

Aside from a few added touches like added S6 badges, mood lighting and extra bits of carbon fibre trim, the Audi S6 is almost identical to the standard A6 model in the cabin. There’s plenty of adjustment in the steering wheel and driver's seat so it's easy to find a comfortable position. The materials are of high quality and combine to give a premium finish while the Multi Media Interface can seem a little fussy at first, but after a little bit of getting used to, is still one of the best systems available.

The large sat nav screen also makes directions and maps easy to read. The large size of the car, and the large windows and windscreen, means visibility is very good. At almost five metres long the S6 can be a little daunting when parking in tight spaces though the standard sensors do help out in most situations.

Like the standard A6, the Audi S6 comfort levels are high for both front and rear passengers. There’s plenty of headroom in the back, and legroom for the two passengers behind the driver and front passenger is ample. The middle seat in the rear can be a little cramped, however, due to the large transmission tunnel. The car is well insulated against road and wind noise.

Engine noise is still audible - the V8 rumble is a little treat for the purists. The ride can be a little hard, mainly due to the stiff suspension and large alloys – something that should be expected on a high-performance saloon. It will still cruise fairly comfortably along the motorway but any undulating roads littered with potholes can be a little uncomfortable.

The seats provide good support, and the side bolstering is excellent and useful for any quick cornering.
