The lightweight, low-friction, 4-cylinder engine in the Civic Hybrid 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 that's less than 2.5" wide. Power for the motor is stored in an 8"-thick battery pack behind the rear seat, which leaves plenty of room in the trunk. And you can be sure of a long battery life since it comes with an 8-year/80,000-mile limited warranty.*good interiors nice looks mileage is ok ,the car is smoothcopied features from accord.
