Valvetronic is a designation for BMW engines equipped with a variable valve lift system. It is a system that, combined with variable valve timing, allows changing the position of the camshaft independently of the position of the crankshaft. It can also change the lift and length of time the valve is open.

This technology is used to optimize engine parameters. Thanks to the Valvetronic system, engines achieve higher performance, lower fuel consumption, and lower emissions.
