The 2.4-liter, dual overhead camshaft (DOHC) i-VTEC 4 cylinder engine is designed to meet the Accord’s fuel-mileage and lower-emissions goals.

The single-overhead-camshaft SOHC VTEC® system is designed to deliver both high performance and high fuel efficiency. Four valves per cylinder and a 3-rocker VTEC enhance performance and power.

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.

Instead of a mechanical linkage from the accelerator to the fuel-injection throttle, the Accord Coupe uses “Drive-by-Wire” technology. The system uses an electronic position sensor connected to the accelerator pedal that sends an electronic signal to the Powertrain Control Module (PCM).
