Recently snapped near the Nürburgring, the high-performance wagon is heavily camouflaged but there’s no hiding the fact that this isn’t your ordinary Avant. While much of the design appears to carryover, the S6 Avant features a sportier suspension and a reduced ride height. The performance changes don’t stop there, as the prototype is equipped with an upgraded braking system with larger front and rear discs.
The rear of the car is notably sportier as it features a modified bumper and four-tailpipe exhaust system. We can also expect a handful of other styling changes including faux aluminum mirror caps and plenty of S6 badging.
The interior should echo the standard model and this is good thing as the cabin is both luxurious and high-tech. Speaking of the latter, we can expect a 12.3-inch digital instrument cluster, a 10.1-inch infotainment system and an 8.6-inch lower display for climate control and convenience features. The model should also be offered with an assortment of upscale options including a 19-speaker Bang & Olufsen premium audio system and front seats with heating, ventilation and massage functions.
There has been a lot of speculation about what will power the S6 and the latest rumors suggest the car will come equipped with a twin-turbo 2.9-liter V6 engine that is shared with the RS4 and RS5. The engine produces 450 PS (331 kW / 444 hp) in those models but reports have suggested the S6 could be even more powerful. Regardless of the final numbers, we can expect the wagon will be able accelerate from 0-100 km/h (0-62 mph) in around four seconds or less.
