But I'm sure whatever boosted engine they put in, it's gonna be easily tunable! But that V8 from the S6 makes 560hp/600lb-ft with just a tune, that would be a insane for an M3/M4 rival!!
FWIW, The S6 motor is way under rated from the factory. Actual output is like 460-480hp and a roughly equal amount of torque. This has been shown on multiple independent dynos. If feels a bit freaky when something this big moves so fast.

Still, the S65 is, subjectively, a more enjoyable motor.
Yeah, I know this engine is largely underated, and the coolest part is that these Audis F/I engines can generally take a lot more then what they come with so no worrys to have when getting an aftermarket tune!! And yeah the S65 is totally a piece of art and that 8300rpm melody is truly something special but I almost certain that 600lb-ft of torque in a small german sport sedan could make me forget about it! But for sure the best thing is still to have both like you do! Please do me a favor, go tune your S6 and come back with a review!

By the way, what does "FWIW" stands for?!
