The new 2011 Audi A8 is set to go on sale later this year, however, most of us are waiting to see what Audi has in store for the next-generation S8. A prototype of the next-generation Audi S8 was recently caught at the Nurburgring and sources say that power will come from a Lamborghini-derived V10.

So how powerful will the new Audi S8 be? Insiders say that the 5.2L V10 will follow the RS6′s forced-induction recipe with direct-injection and twin turbos that will help produce around 620-hp with a maximum torque of 553 lb-ft. That’s significantly up from the old S8′s 444-hp and 398 lb-ft.
