What's strange was that on the same day the RS4 beat the CSL easily, the CSL beat the Z4MC (just) and the RS4 beat the Z4MC (just) - and when I say just, I mean there was less than a car-length in it at the end.

I do wish they'd get their equipment mounted properly for the runs, and maybe even have a couple along the runway to give us a better sense of the speed, noise and gaps.
