BMW are using this technology and possibly have released it in some production engines as it has been a long time since ive read about it on autospeed.

the valves can be controlled by the ECU for duration and lift and because of this they do not need a throttle buttlerfly as the valves are what control how much air going into the engine from accelerator pedal input (as well as other sensors).


has huge advantages for fuel economy, power and drivability as it is a true dynamic variable valve engine.

hope this helps.
