Variable Valve Timing: Description and Operation

VarioCam Plus Control on V8 DFI Engines

VarioCam Plus technology is used for the first time in V8 engines in the Cayenne model range. This system, which may be familiar to you from the current sports car generation, enables intake valve lift switching in addition to intake camshaft adjustment. This ensures optimum running quality, low fuel consumption and low emissions as well as high power and torque ratings in conjunction with the intake system.
