Integrated Motor Assist IMA®
Talk about the perfect blend of power and efficiency. At the heart of the Civic Hybrid is the sophisticated Integrated Motor Assist IMA® system. IMA pairs a 1.5-liter, i-VTEC® 4-cylinder gasoline engine with an electric motor. Although the engine alone provides sufficient driving performance, when additional power is required, a permanent-magnet electric motor mounted between the engine and transmission provides power assist. Under certain conditions, the electric motor can propel the car on its own. Together, the motor and engine produce 110 hp @ 5500 rpm (SAE net).
The 1.5-liter, single overhead camshaft, aluminum-alloy i-VTEC® 4-cylinder engine uses state-of-the-art engineering technology to produce impressive power, yet it still helps the Civic Hybrid obtain excellent fuel-economy ratings and an Advanced Technology Partial Zero-Emission Vehicle (AT-PZEV) rating, all on regular gasoline.

 AT-PZEV (Advanced Technology Partial Zero-Emission Vehicle) models as certified by California Air Resources Board (CARB) and states that have adopted California Zero-Emission Vehicle regulations.
The IMA electric motor works in conjunction with the gasoline engine and supplies additional 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.
Continuously Variable Transmission (CVT)
Honda’s continuously variable transmission (CVT) provides an outstanding driving experience and allows the engine to always operate at the most efficient rpm level, enabling it to maximize efficiency under all driving conditions.

Drive-by-Wire Throttle System
The Drive-by-Wire throttle system helps enhance the driving character of the Civic Hybrid. With smart electronics connecting the throttle pedal to the throttle butterfly valve in the intake manifold, the engine response can be optimized to suit the driving conditions and to better match your expectations.
