On average you blink about 10 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 engines with the Auto Start Stop function incorporate 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.
