Some incredible driving
 

This is probably one of the best videos of racing and some of the greatest driving skills I’ve seen. Major respect to both drivers on this very difficult course. Had my adrenaline pumping for the entire 6 minutes ...

Wow ! Ty for post.

Amazing how how evenly matched cars are.

Great stuff! Cars seemed to have equal power, (GT3 Class?), so it looked the aero was what kept the R8 ahead of the AMG GT3 on the long straights.

Looks like a video game.

Great video. Is the POV driver close enough to get any benefits from drafting?

Advantage AMG on braking and mid torque. Audi top end.

That was a great video that takes skill and some balls to drive like that

great video, can't say i'd be enthusiastic about hat steering wheel.
whack a curb hard and it's broken thumbs.

Yep, 6.2 V-8 is a torque monster . Audi V10 needs hp is top end.

This car still has the old naturally aspirated SLS engine as you stated. So lots of hp, no so much torque (less than a regular GTS) but a 700lbs diet along with some impressive aero.

Actually, the 6.2 had a incredible flat torque curve with no lag when set up for racing. We ran this engine in a CLK63 BS in the Pirelli World Challenge so I have first hand knowledge how it stacked up against other makes.. Only the Cadillac's had more out of the corners. Audi had just come out with their factory gt3 car and lobbied for much bigger tire set up which immediately put them in the hunt. At that time GM was the only manufacturer totally involved. Mercedes AMG suggested we not continue racing but would support us if we campaigned an SLS. That's was about $350K with a spares package double that for travel for a season and you can see it's an expensive. Gradually all the factories got involved with furnishing drivers or actual tech support until their GT3 models came on line. Sorry I digress.
