The folks at were lucky enough to get some shots of the upcoming Audi S8 during winter testing, which you can see in the pictures. The bodywork on the car you see here is that of a standard A8, which will obviously be modified for the S8 during production. We know it’s an S8, however, because of the bigger brakes and quad exhaust system you can see below.

We don’t know much else about the S8 yet, although speculation says it will be receiving its power from a turbocharged 4.2-liter V8 instead of the V10 we originally expected. Regarding design:

Audi’s design director Stefan Sielaff told Autocar at the A8’s launch last year that the S8 would “create a new design grammar which will also go onto the next S6, S7 and S1”.

Sielaff also said there would be an increased use of both aluminium and carbon fibre in the cabins of future S models to make them more special than the standard cars.

Expect to see full details on the S8 later this year for a launch in early 2011. No word yet on whether it’s coming to the States, but unfortunately it seems unlikely.
