The B58 is part of BMW's new modular engine family, each engine using a displacement of 500 cc (30.5 cu in) per cylinder, following the B38 and B48engine.[3]

The B58 engine was named Ward's 10 Best Engines in 2016 (installed in the 340i),[4] 2017 (M240i),[5] 2019 (X5)[6] and 2020 (M340i).[7]

The S58 engine, which was released in early 2019, is the high performance version of the B58.[8][9]


Compared with its BMW N55 predecessor, the B58 features a 20% increase in boost pressure, a closed-deck engine block design, an increase in compression ratio to 11.0:1 and a slight increase in displacement from 2,979 to 2,998 cc (181.8 to 182.9 cu in) with added weight of 8 kg (18 lb).

The intercooler - a water-to-air design - is integrated into the intake plenum, to reduce the volume of air between the turbocharger and the cylinders.[10]

As per the N55, the B58 also features a single twin-scroll turbo, direct fuel injection, variable valve timing (called double Vanos by BMW), variable valve lift(called Valvetronic by BMW).[11][12] The redline remains at 7,000 rpm, the boreand the stroke is 82 mm × 94.6 mm (3.23 in × 3.72 in).

The B58 also features an engine-mounted heat encapsulation system to reduce engine wear and emissions during start-up.[13]

As a part of BMW's new modular engine family, the crankcase is a completely new design identical to the B57 diesel version,[14] engineered as both a gasoline and diesel engine in one common part. The closed deck crankcase is equipped with a completely new structure which can be identified by a complex array of ribs on the exhaust and intake side and an additional reinforcement frame on the oil pump side.
