Integrated Motor Assist

Honda's Integrated Motor Assist (IMA) System couples a gasoline engine with a small electric motor for added power. The majority of the efficiency gains are through the reduced size of the gasoline motor. Some of the energy used by the electric motor, such as under high load acceleration conditions, can be recaptured when applying the brakes (equipped with Honda's Regenerative Braking System. This energy is held and stored as power in the battery pack. Under acceleration, the stored energy is used again, contributing to vehicle performance while reducing fuel consumption.
