With its flexible use of cylinders, the unique VCM (Variable Cylinder Management)
technology virtually gives you three engines in one car. During start-up, accelerating
or heading uphill, it will fire all six cylinders to give you the maximum power.
Once you've reached cruising speed, it would automatically drop down to four cylinders,
or even three, if it is an easy cruise. This maximizes both performance and fuel
economy.
To achieve the same quietness and smoothness, as when running on all six cylinders,
new Active Control Engine Mounts (ACM) and Active Noise Control (ANC) systems have
been designed to complement the VCM technology.
