Silver BMW M4 Spied In Germany

A pre-production version of BMW's new M4 performance coupe has been spotted in a German parking lot, just weeks since its global online debut. 

Coming as one of the first 'real world' photo sets, these images reveal the new hero coupe in BMW's Silverstone Metallic finish - a rather more conventional shade than the Phoenix Yellow-like finish used in the press shots. 

The M4 has yet to go on sale - its official debut is set for next month's Detroit Auto Show - and we can expect a local debut to occur early in the second half of 2014.
