The BMW M4 is in pre-production form now, as AutoGuide’s spy photographers have caught a non-black M4 testing at Nurburgring.
Previous spy photos featured a black prototype; but now that a white model has been spied, the German automaker has moved onto the next stage of testing and hopefully means the M4 might debut soon – perhaps the Frankfurt Motor Show later this year.

The new M4 is expected to make at least 400 hp thanks to a turbocharged, inline-six powerplant. Weight savings from switching to an inline six from a V8 will also make the M4 a more agile sports car.
