The BMW B38 is a 1198 and turbocharged straight-three DOHC petrol engine, which replaced the straight-four BMW N13. Production started in 2013.

It is part of a modular BMW engine family, of straight-three (B38), straight-four (B48) and straight-six (B58) alloy block and head petrol engines, which use a displacement of 400 cc per cylinder in the 1.2 and 500 cc per cylinder in the 1.5. It specifically shares a lot of components with the BMW B37, due to their same size/configuration.

The B38 is used in front-wheel drive cars (such as the Mini Hatch and BMW 2 Series Active Tourer), as well as BMW's traditional rear-wheel drive and all-wheel drive (xDrive) configurations. The first car to use the B38 is the BMW i8 hybrid sports coupé, where it is used as a transverse mid-mounted engine.

Design

The B38 features direct injection, an 11:1 compression ratio, variable valve timing (double-VANOS) and the single-scroll turbocharger with the world's first aluminium turbine housing, manufactured by Continental.

On the 1.2liter versions, the bore is 78 mm and the stroke is 83.6 mm. On the 1.5liter versions, the bore is 82 mm and the stroke is 94.6 mm.
