The new sports saloon could come with upwards of 450bhp.

Audi’s lineup is currently undergoing a major makeover – following on from the debut of the all-new A7 and A8, the German car maker is all set to pull the sheets off of a completely revamped A6 in the coming months. So far we’ve seen a handful of prototypes, but new video shows the more powerful S6 sprinting around the Nürburgring.

This is the second time we’ve seen the S6 on camera – the first instance came in June and showed a highly camouflaged S6 doing its best supercar impression around the Nordschleife. Now for the first time we have that same prototype on video, giving us an even better look at the upcoming performance saloon.

The new video doesn’t give us much else in the way of details, unfortunately. The S6 is still covered almost entirely in camouflage – a few defining features such as a more sculpted grille, sleeker headlights and quad exhaust tips can be seen – but it’s the sound of the engine that should entice any prospective buyers.

Though unconfirmed, the new Audi S6 is expected to produced upwards of 450bhp and power could come courtesy of either a 4-litre twin-turbo V8 or a smaller turbocharged V6. A diesel option is even being rumoured for both the S6 and the larger S7. 

Riding on VW Group’s new MLB Evo platform – the same platform that underpins cars like the A5 – means that the new S6 will shed a few kilos over the outgoing model and should gain some added sporty driving pleasure in the process. Expect the new Audi A6 and S6 to make their debut sometime early in 2018, perhaps in time for the Geneva motor show in March, before going on sale later in the year.
