The B48 is part of a modular BMW engine family of 3-cylinder (B38/ B37), 4-cylinder (B48/ ye) and 6-cylinder (B58) engines,[1] which use a displacement of 500 cc (30.5 cu in) per cylinder.
Compared with its N20 predecessor, the B48 uses a more undersquare design, and engine block in "closed-deck construction".[2] As per the N20, the block and head are made from aluminium.[3] Other features shared with the N20 include a twin-scroll turbocharger, direct injection, variable valve lift (Valvetronic) and variable valve timing (Double VANOS).[4]

Introduced in May 2019 this engine features a reinforced crankshaft with larger main bearings and new pistons with a lower 9.5:1 compression ratio, this allows the engine to take more boost pressure from a larger turbocharger, which blows compressed air through a reworked intake tract.[12] [13]
