Variable Cylinder Management™ (VCM) (V-6 Engines)


This technology enables a V-6 engine to provide full power on demand while also delivering impressive fuel economy. When maximum power isn’t needed, the VCM system can deactivate one bank of cylinders—depending upon the torque requirements to maintain cruising speed—by shutting off the appropriate fuel injectors and stopping valve operation with the VTEC® system. And when full torque output is required, all six cylinders are employed immediately.
