BMW 4 Series Generations — F32/F33/F36 vs G22/G23/G26
F32 (2014–2020): N20/N55 — essentially F30 3 Series in coupe form, classic proportions. F33 convertible; F36 Gran Coupe 4-door. G22 (2021+): B48/B58 — wider, more divisive styling. G23 convertible; G26 Gran Coupe. M440i B58 is the performance sweet spot — 374hp without full M4 running costs. Malaysia used: G22 430i best value.
4 Series Generations
- F32 Coupe / F33 Convertible / F36 Gran Coupe (2014–2020): RWD/AWD, N20 or B48/N55, ZF 8-speed
- G22 Coupe / G23 Convertible / G26 Gran Coupe (2021+): RWD/AWD, B48/B58 only, ZF 8-speed — much more reliable
- Buy tip: skip N20-powered F3x; target B48 F3x (2018–2020) or any G2x
Which Generation to Buy in Malaysia
When choosing a used 4 Series in Malaysia, the engine generation is more important than the year. Models with N20 engines carry timing chain risk regardless of mileage; models with B48/B58 engines are significantly more reliable. Check the engine code on the service sticker before making any offer. For peace of mind, target B48/B58 powered variants with documented service history under 100,000 km. At 4M Car Care we provide free generation identification and risk assessment for any 4 Series you are considering.
