What coefficient do they use for power train loss on the E63? I'm assuming it's in the 10-15% range, in which case yours would be right on the factory flywheel figures, so very good result.
In next months Evo mag there is a 3 way between E63S estate, XFR Sportbrake and RS6 avant. E63 comes out on top, just.
cheers, Steve
