All four-cylinder gasoline engines are part of BMW EfficientDynamics, the innovative technology package that consistently propels the optimisation of the engine. At the centre of this is the BMW TwinPower Turbo technology, which combines a TwinScroll turbocharger with Valvetronic, double-Vanos and High Precision Injection. The high compression ratio and the precise, electronically-controlled injections that target the spark plugs ensure good airflow and highly-efficient fuel combustion, so the engines stay economical even at high speeds.

This results in impressive performance values, even power delivery and unparalleled running smoothness over the entire speed range, as well as markedly more efficient fuel consumption and emission values.

BMW 4-cylinder gasoline engines are available in different variants (only two examples listed below).
