Increased wheel losses? About 20 BHP more losses at 7000 RPM than 6000 RPM on a 400 BHP car? Maybe an overestimate from a rolling road and more like 15 BHP extra losses. Still significant?

The losses are just a function of the speed ie gearing, running the same car in 3rd gear will show much lower losses
