3.4 seconds versus 3.5 seconds zero to sixty, but the S8 is heavier?
I heard the dual intake of the S8 make the engines on par?
Please she'd some light
The S8 & RS7 share the same engine basically. And I say basically because the housing in the RS7 is very different, and therefore, the biggest change was made to the intake of the Turbos shaping into a V, and much closer to main compartment. In a way many are right - boost pressure goes way up with that much logistics put into it. I'm sure to make it fit, a few things were "tweaked" along the way, but from what I understand, this is more powerful in almost every aspect. It shares the engine put into the Bentley C. GT (with more horsepower & boost). It can take a F40 up to at least 70, and give an R8 a run for its money! It will be a while before we see a lot of these head to heads - ppl still need to break them in!
I leave the floor to the engineers and audi guru's however, I'm just a simple being
