Looking slightly sporty than the standard sedan, the S6 features an S line exterior with unique bumpers and side skirts. The car has also been equipped with honeycomb mesh inserts and a sport-tuned suspension that likely reduces the ride height by a few millimeters.
While the front of the car closely resembles the A6, there’s no mistaking it from the rear as the S6 has a four-tailpipe sports exhaust system. The model also features a unique lower bumper.
Rounding out the styling changes are a set of attractive alloy wheels which cover an upgraded braking system with silver calipers. The production model should also have faux-aluminum mirror caps and the obligatory S6 badging.
The minor styling changes will likely continue in the cabin as we can expect a sport steering wheel, revised trim and alloy pedals. There should also be new upholstery combinations as well as a 12.3-inch digital instrument cluster, a 10.1-inch infotainment system and a lower 8.6-inch display.
There has been a lot of speculation about what will power the all-new S6 and early reports claimed the car would have a turbocharged 4.0-liter V8 engine. However, that doesn’t seem to be the case as the most likely candidate is the twin-turbo 2.9-liter V6 that resides in the RS5 Coupe and Porsche Panamera 4S. The engine produces 444 hp (331 kW / 450 PS) and 443 lb-ft (600 Nm) of torque in the coupe and it’s believed the S6 will have roughly the same output.
