Honda makes a variety of Civics, its economical compact car. But none will be more economical than this version, the 2012 Honda Civic Natural Gas. Per gallon, natural gas can cost half as much as gasoline, while getting similar fuel economy.
The displacement of the four-cylinder engine, 1.8 liters, is the same as in other Civics, but Honda gave it a fuel delivery system that pumps compressed natural gas into the cylinders. Using this fuel reduces horsepower from 140 to 110.
Despite the lower power, the Civic runs along reasonably well, tackling most traffic situations without problem. Its acceleration is fairly slow, however, so drivers will want to be careful about passing and merging maneuvers.
The digital speedometer, flanked by fuel and temperature gauges, sits just below the windshield. The instrument cluster changes to green when the car is driven economically. To the right of the gauges is the i-MID.
