No, VVT is to be introduced on the 5.3 in 2010
According to Wikipedia, a variable valve timing is a "process of altering the timing of a valve lift event, and is often used to improve performance, fuel economy or emissions".
Variable valve timing.
Variable timing valve train
This component is electrically operated by the engine computer. It (on most vehicles) changes the oil pressure in the variable valve timing system to adjust the valve timing. It is very similar to the solenoids in use inside an automatic transmission.
variable valve timing is where the engine changes valve timing based on the driving situation much like ignition timing is changed to meet the needs of the engine in specific situations. in most cars valve timing is static and determined by the timing gear on the camshaft
Variable Valve Timing with Intelligence
it means charge motion variable timing intelligent this have no relation with CVT (continuous variable transmission) and continuous variable valve timing
no it does not only cars with variable valve timing do
It Means Variable Valve Timing Technology - Intelligence
Intelligent Variable Valve Timing and Electronic Lift Control
