Former F1 driver Timo Glock hunts DTM teammate Andy Priaulx at BMW's Maisach test loop outside of Munich. If you were concerned about the M3 getting soft, this should help put you at ease.

Drivers evenly spaced, cars departing in a neatly scheduled fashion, only when the previous car had returned to the pit. The men in suits turned their backs for one minute and the next thing you know, Timo Glock, ex-F1 and current BMW DTM driver has taken off right behind touring car legend and teammate Andy Priaulx - and he's doing his damndest to hunt him down through the cones.
