An exact science.

The four-cylinder diesel engine in the BMW 120d.

Instantaneous throttle response right across the rev range and impressive torque of 350 Nm: third-generation common rail injection in the BMW 120d ensures exceptional performance in hand with unbeatable fuel consumption levels. The fuel injection system operates at pressures of up to 2,000 bar and electronically controls injectors allowing them to deliver exact amounts of fuel to the engine's combustion chamber. And thanks to the engine block now being made solely of aluminium, weight is reduced by an enormous 20 kg.
