Variable Cylinder Management™ (VCM®)
On Accord Coupe V-6 models with automatic transmission, the V-6 engine 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 savings. When maximum torque is required, all six cylinders are firing. During steady cruising speeds, VCM shuts down one bank of cylinders. In this mode, the audio system’s Active Noise Cancellation™ (ANC) function 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 every mode, engine mounts automatically adjust their firmness to help absorb energy. The transition between the three operating modes is completely seamless and goes unnoticed by the Accord’s passengers.
