The 2009 Honda Civic Hybrid, a 4-door 5-passenger sedan, uses a gasoline/electric hybrid engine to maximize fuel economy with a 1.3L four-cylinder engine that generates 110 hp paired to a continuously variable transmission (CVT). Honda Hybrid performance tops the Civic lineup with fuel economy of 40 mpg city/45 mpg hwy and 42 mpg combined. Hybrid models are equipped similarly to the Honda Civic EX and have automatic climate control. They can also be equipped with an optional navigation system, leather seats and heated seats. Standard safety equipment includes antilock brakes, front-seat side airbags, full-length side curtain airbags, active front head restraints and stability control. Civic Hybrids have a slower acceleration time than other models and only around 10 cubic feet of truck space, due to the space taken up by the hardware of its gasoline/electric power train.
