BMW’s luxury coupe line that debuted in 2013 is the 4 Series.
BMW created the 4 Series by separating the two-door coupe and convertible versions of the 3 Series into their own numbered range. The move gave BMW a clearer hierarchy: odd-numbered series generally emphasized sedans and practical body styles, while even-numbered series identified their more style-focused coupe derivatives.
The first-generation 4 Series was built from 2013 to 2020. Its coupe used the F32 designation, the convertible was the F33, and the five-door fastback-style Gran Coupé was the F36. The line succeeded the E92 coupe and E93 convertible versions of the fifth-generation 3 Series, while retaining close mechanical links to the F30 3 Series.
The 2013 launch is sometimes confused with the 2014 arrival of the high-performance M4. The M4 is the performance model derived from the 4 Series, not the name of the series itself. The larger 6 Series and newer 8 Series are separate, more upscale BMW coupe families.
