Chronology
PredecessorBMW 3 Series (E90)
SuccessorBMW 4 Series (G22)

The first generation of the BMW 4 Series consists of the BMW F32 (coupé version), BMW F33 (convertible version) and BMW F36 (four-door coupé version, marketed as 'Gran Coupé') compact executive cars. The F32/F33/F36 has been produced since 2014 and is often collectively referred to as the F32.

The F32 was introduced as the successor to the E92/E93 coupé/convertible models of the fifth-generation 3 Series range. The F32 is produced alongside - and shares many features with - the F30 3 Series. As with the F30 3 Series range, the F32/F33/F36 is powered by turbocharged petrol and diesel engines with 3 cylinders (petrol only), 4 cylinders, and 6 cylinders.

The high performance F82/F83 M4 models were introduced in early 2014.[3] They are powered by the S55 turbocharged straight-six engine.

Development and launch

BMW Concept 4 Series Coupé at the 2013 NYIAS

In 2013, the concept vehicle (called the Concept 4 Series Coupé)[6] was unveiled at the North American International Auto Show.[7][8]

Compared with its E92 predecessor, the F32's wheelbase is 50 mm (2.0 in) longer, the overall length is increased by 31 mm (1.2 in) and the width is increased by 44 mm (1.7 in).[9] The front track width is 1,545 mm (60.8 in) and the rear track width is 1,593 mm (62.7 in), increases of 45 mm (1.8 in) and 80 mm (3.1 in) respectively.
