VANOS is BMW's electronic variable valve timing system. It varies the valve timing in a similar way that a distributor advances and retards ignition timing. VTEC is Honda's system, which switches between two different cam profiles, one for low-RPM and one for high-RPM. BMW's system is more effective, although it is also more complex and expensive.
