Spy Photos: BMW Z4 Coupe on the 'Ring

The 'heads at Pistonheads procured some shots of BMW's production model Z4 Coupe as it was being track-tested on Germany's famed N rburgring. Since the concept version's Frankfurt unveiling, BMW is much less concerned with disguising the coupe, other than the inadvertent obfuscation caused by fitting it with a bunch of electronic sensors that can measure cornering load forces down to the fraction of a g. Gee.
