Audi Variable Valvelift System in Detail Sorry, but Variocam is a valve timing variation system. This, on the otherhand, is a valve lift variation system, meaning it makes the valve open less or more according to the load needs. The main thing here is that this, interesting as it may be, is a variation of a system called valvetronic presented some years ago by BMW. In valvetronic the system goes even further, using the lift variation to totally control the inflow and thus render useless the use of the throtle butterfly. Nice try, though...
