BMW is shaking up its badging strategy and will turn the next-gen 1-series and 3-series sporting derivatives into the 2-series and 4-series.

Two-door Ones and Threes - the coupes and convertibles - will in future be rebadged as the BMW 2-series and BMW 4-series.
Why exactly are they rebadging BMWs as 2-series and 4-series?

Audi and Mercedes went ahead and did it: the A5 Sportback, coupé and convertible are one number more prestigeous and expensive than the more mainstream A4 models; the E-class coupé and cabriolet fetch E-class money despite their well concealed C-class genes.

A decade ago, BMW had exactly the same idea and came very close to sticking a 4-series badge on to the two-door 3-series derivatives. But at the eleventh hour, this plan was withdrawn, allegedly because management feared that a split in registration numbers would be perceived as brand weakness.

This time, however, the sales strategists are reportedly determined to not only revive the 4-series moniker but also to add two new 2-series models.
