The Civic Hybrids lightweight, low-friction 4-cylinder engine features torque-enhancing i-VTEC and a dual-point sequential ignition system that fires two spark plugs per cylinder. The engine is mated to a powerful DC electric motor thats less than 2.5" wide. Power for the motor is stored in a battery pack behind the rear seat. The pack is only about 8" thick, leaving plenty of room in the trunk. And to provide you the assurance of long life, the Civic Hybrids IMA battery pack comes with an 8-year/80,000-mile limited battery warranty. 6 HYBRID TECHNOLOGY The Civic Hybrids engine usually uses the IMA Systems motor to start. If the IMA battery-pack charge is low or if its very cold outside, the system has a separate battery and starter motor to back it up. Any time the engine needs a burst of power like while accelerating, passing or climbing hills the IMA Systems electric motor can add its torque automatically to the engines to give instant, ample response.
