This article is about the BMW engine valve system. For valve electronics, see vacuum tube.
Not to be confused with Valvematic.

The Valvetronic system is a BMW variable valve lift system[1] which, in combination with VANOS, allows infinite adjustment of the intake valve timing and duration.[2] The system claims to improve fuel economy and emissions, and negates the need for a throttle body in regular use.
