The Accord Hybrid utilizes the third-generation of Honda's advanced Integrated Motor Assist (IMA) full hybrid system in combination with new Variable Cylinder Management (VCM) cylinder deactivation technology to deliver the world's best V-6 fuel efficiency – on par with a 4-cylinder, compact class Civic – along with highly responsive and powerful V-6 performance.

The IMA system's 12-kilowatt, high-output, electric motor contributes more than 100 lb.-ft. of torque to the Accord Hybrid's 3.0-liter V-6 engine during hard acceleration and recaptures kinetic energy generated during deceleration and braking for storage in the IMA system's advanced nickel-metal hydride battery pack. When cruising at steady speeds where less engine power is required, the VCM system deactivates the V-6 engine's rear bank of cylinders, closing both the intake and exhaust valves for reduced fuel consumption.
