The BMW N57 is a family of aluminium, turbocharged straight-6 common rail diesel engines. The engines utilize variable geometry turbochargers and Bosch piezo-electric injectors.[1] The engine jointly replaced the M57 straight-6 and M67 V8 engines. In 2015 the N57 started to be replaced with the B57 engine, beginning with the G11 730d.
