EPA Fuel Economy: 44/44 mpg
Whereas the first four entries in this list are unique vehicles specifically designed as hybrids, the Civic hybrid is one of several normal vehicles that were subsequently adapted for hybrid propulsion. In the case of the Honda Civic hybrid, that meant joining a 1.5-liter inline-four gasoline engine, a 23-hp electric motor, and a lithium-ion battery back. Peak combined outputs of 110 hp and 127 lb-ft don’t make for speedy acceleration, but the hybrid is the most fuel-efficient version of the 2012 Civic by a wide margin.
The hybrid also is the second-most expensive Civic sedan, with its price tag eclipsed only by that of the Civic Natural Gas. Fortunately, a long equipment list makes the sticker price more palatable: automatic climate control, a six-speaker sound system with Bluetooth and USB connectivity, power locks and windows, and lightweight 15-inch alloy wheels are all standard.
