Nice.
So the pic of the speedometer with 8000 +rpm redline confirms that it is a carryover of the RS4 engine with some upgrades!
I don't think it can be a V10(never did).
And forced induction would have had a lower redline rating.
Hmm, one thing I'm sure about is that, who ever owns this car will have a sweet sounding V8. I just love the noise made by this engine.
