the engine's variable-length intake manifold (vim) switches between a long intake manifold at low engine speeds and a short intake manifold at higher engine speeds. proton cars use a longer intake manifold to achieve slower air flow; as it was found that promotes better mixing with fuel. the short intake manifold allows more air in faster. this is beneficial at high rpms.

in 2001, bmw introduced the valvetronic system. the valvetronic system can continuously and precisely vary intake valve lift, and in addition, the independent double vanos system can concurrently vary the timing for both the intake and exhaust valves. the precise control the system has over the intake valves allows for the intake charge to be controlled entirely by the intake valves, eliminating the need for a throttle valve and greatly reducing pumping loss. the latter alone can boost both power output and fuel economy 10-15%. furthermore, both systems can also be combined with bmw diva (differentiated variable air intake) system which is the world's first continuously variable length intake manifold. as 2017 bmw is the only company which can implement all three variable valve timing, lift and intake manifold in continuous adjustment form on production car.
