Constant precision.

The four-cylinder petrol engine in the BMW 120i.

On average you blink about ten times a minute. In this time you miss 2,000 separate fuel injections supplying as little as 2 mg of fuel each time. This exceptional level of precision is made possible by the piezo injectors, located centrally between the valves. The engine in the BMW 120i with Auto Start Stop function incorporates this cutting-edge technology allowing them to operate in lean-burn mode for far longer and at far higher revs. This leads to improved efficiency, as well as to greater performance. Better performance from less fuel - what BMW EfficientDynamics is all about.
