BMW N57

The BMW N57 is a family of aluminium turbocharged straight-six common-rail diesel engines that jointly replaced the M57 straight-six and the M67 V8. The engines use variable geometry turbochargers and Bosch piezo-electric injectors. The N57D30Ox versions run at 1,800 bar of fuel pressure and the N57D30Tx versions at 2,000 bar, with the O versions using a single turbocharger, the T versions twin turbochargers and the N57S three turbochargers of varying size, all with a bore and stroke of 84 by 90 millimetres. BMW offered an M Performance Kit for the N57D30O1 in some markets that raised output to 210 kW and 600 newton metres of torque. The engine powered the E90 3 Series, the F30 3 Series, the F10 5 Series, the F07 5 Series Gran Turismo, the F01 7 Series and the E70 X5 and E71 X6.
