Variable Cylinder Management (VCM®)
The Crosstour's V-6 features the latest generation of Variable Cylinder Management (VCM®) technology. This system can activate and deactivate the engine's cylinders as needed to meet the demands of both acceleration and fuel efficiency. When maximum torque is required, all six cylinders are firing. During steady cruising speeds, VCM shuts down one bank of cylinders. In this mode, Active Sound Control (ASC) generates out-of-phase sound waves to cancel out any undesirable noise that may be due to the harmonics of 3-cylinder operation. As cruising speed increases, the engine moves to a 4-cylinder mode for extra cruising power. To help keep engine vibration from reaching the cabin in any mode, active engine mounts automatically adjust their firmness to help absorb energy. The transition between the three operating modes is nearly seamless and goes unnoticed by the Crosstour's passengers.
