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 lift.[2] The system claims to improve fuel economy and emissions, and *negates the need for a throttle body in regular use.*
- Needs reference. Throttle body is needed for externally metered air intake for engine to operate.*
First introduced by BMW on the 316ti compact in 2001,[2] Valvetronic has since been added to many of BMW's engines.
