BMW to rename 1 and 3 Series coupes as 2 and 4 Series

Word from Car Magazine has it that the Bavarian automaker is preparing to launch the next-generation versions of its 1 Series and 3 Series coupes and convertibles as the 2 Series and 4 Series, respectively.

The move would correspond well to the 6 Series, the coupe and convertible that sits between the 5 Series and 7 Series sedans. It's not the first time BMW has considered such a move, having come close to spinning the two-door 3 Series into a 4 Series about a decade ago.

Audi recently completed a similar shift, replacing the A4 convertible with the A5. That model has since spawned a five-door Sportback, in whose company BMW may soon find itself with the 3 Series GT that may likewise be badged as a 4 Series.
