'''VANOS''' is a [[variable valve timing]] system used by [[BMW]] on various automotive [[petrol engine]]s since 1992. The name is an abbreviation of the German words for ''variable camshaft timing'' ({{langx|de|'''va'''riable '''No'''ckenwellen'''s'''teuerung}}).

The initial version (retrospectively renamed "single VANOS") was solely used on the intake camshaft, while the later "double VANOS" systems are used on intake and exhaust camshafts. Since 2001, VANOS is often used in conjunction with the [[Valvetronic]] variable valve lift system.
