Name Game: BMW may rebadge iconic M3

It's clear BMW wants to adopt an alphanumeric naming system, but according to an American news outlet, the Bavarian marque is thinking about renaming all coupé variants of the upcoming 3-Series the '4-Series', as it already does with the 5-Series based 6-Series, and X5-based X6 Coupé.

It's likely the next M3 will retain its nameplate, while BMW may develop a 4-Series based M-Coupé called M4 to replace the current M3 sedan.

The next M3 will go on sale in 2015.
