Integrated Motor Assist IMA®
The IMA® electric motor works in conjunction with the gasoline engine, and supplies additional power and torque in assist mode. The motor's ultra-thin design allows it to be mounted between the engine and the transmission. The motor also functions as the generator for the IMA® system during deceleration, and as a starter, quickly spinning the engine up to idle speed.
