I believe they later built the v10 version with the s85. Sounds like they cannot make up there mind with the amg engine, then s65 then s85. Just pick one already!
It really had abissmal performance on the top gear track. It weighs something like 2600 pounds and only was 1.5 seconds ahead of the m3. Sometimes weight is not everything as bmw has shown with their magic wand and ability to defy the laws of physics.
Either way the car is ugly and sucks but I was interested in how they pumped out 470 hp out of the s65.
I truly believe the s65 should have been released with 450hp stock, redline of 8600 stock and it would have been that much more able to beat up the C63 in horsepower wars as well as all the other things it does better
