Up until 2014, BMW M models used the same model codes as the rest of the model range.
However, the F32/F33/F36 generation was one of the first where the M models use separate model codes: F82 for the coupé and F83 for the convertible.

The F82/F83 M4 is powered by the S55 twin-turbocharged straight-6 engine rated at 431 PS (317 kW; 425 hp) and 550 N⋅m (406 lb⋅ft).
The gearbox is either a 6-speed manual (with throttle blip on downshifts) or a 7-speed dual clutch transmission (M-DCT).

The M4 also features an electronically controlled limited-slip differential, electric steering, additional bolted joints between the axle subframe and the body sills, aluminium stiffening plate and a five-link rear suspension constructed from aluminium Carbon-fibre is used for the roof, bootlid, strut brace and driveshaft.
Unusually, the suspension subframes are directly connected to the chassis without rubber bushings.
An optional head-up display comes with additional M-specific functions such as a gear display, rev counter and Optimum Shift Indicator.
