Design, development and variant notes
The B37 is a three-cylinder, 1,496 cc diesel in BMW's modular engine family. Wikipedia describes a single variable-geometry turbocharger and a 16.5:1 compression ratio.
It shares aspects of the modular architecture with the petrol B38, but diesel and petrol components and calibrations should not be assumed interchangeable.
