The forthcoming 2019 model-year Audi S6 sedan has now been spotted free of camouflage, following the sightings of its Avant (station wagon) sibling earlier this year. Subtlety is the name of the Audi S-model game, and so it proves with the S6 development vehicle seen here.
As with the S6 Avant, changes on the S6 sedan from the standard A6 are subtle in the extreme, at the front-end of the car at least. Different wheels and a slightly lower ride height feature here, which will be due to a revised chassis setup to suit the heightened performance capabilities of the car.
The most apparent tell-tale sign of an S-model Audi is the quartet of exhaust tips around the back, which reside within a deeper rear bumper. These scavenge exhaust gases from the powerplant which, though unconfirmed, has been widely tipped to be the 2.9 litre biturbo V6 from the current RS4 and RS5, as well as the Porsche Panamera 4S. The 4.0 litre biturbo V8 is expected to be the RS6’s reserve.
Elsewhere within the car, the S6 can be expected to feature the cream of the A6 equipment crop, including the 10.1-inch and 8.6-inch touchscreen displays along its centre console. The full complement of driver assistance systems can be expected here, too. As for it market arrival, the Audi S6 sedan could make its debut later this year alongside the S6 Avant.
