The new nomenclature says M4, but for all practical purposes you can put that to one side.
Ultimately, however, selling an M3 for the road was more compelling than racing it. Later versions of the M3, such as the six-cylinder E36 (1992-1999) and E46 (2000-2006), were road cars first.
There are two things of note this time around. First is the return of a six-cylinder engine – two more pots than in the first M3 but two fewer than in the just-departed version.
Second is the arrival of turbochargers to keep the power output of the downsized engine appropriate for a new performance car. It follows a now-familiar formula: more powerful, faster, lighter, cleaner.
