4 Series Engines Through the Generations

F32/F33/F36

F32/F33/F36 2013–2020

launched as the coupe/convertible/Gran Coupe spin-off of the F30 3 Series, sharing its entire N20/N55/N47/N57 range before the 2015-2017 transition to BMW's B-series family.

G22/G23/G26

G22/G23/G26 2020–Present

continues the platform-sharing relationship with G20 3 Series, running B48/B58/B47/B57 across the range with 48V mild-hybrid assistance on higher-output variants.

4 Series Engine Buying FAQs

A

10 confirmed engine families, mirroring 3 Series almost exactly given the direct platform relationship.

A

Use the registration checker on this page — body style (coupe/convertible/Gran Coupe) does not affect engine range within a generation.

A

Legacy N-series applications have well-established used-donor supply. Current B-series and M-specific S-codes more commonly favour reconditioned.

A

Reconditioned engines carry a 12-month, unlimited-mileage warranty on internal mechanical components. UK mainland delivery by kerbside pallet, typically 2–4 working days, with 14-day uninstalled returns.
