Available nationally to qualifying Honda dealers, the Civic Natural Gas is powered by a dedicated natural gas variant of the 1.8-liter inline 4-cylinder engine similar to the one used in the Civic Sedan and Civic Coupe. The Civic Natural Gas engine produces 110 horsepower and 106 lb-ft. of torque. Compared to the previous generation, torque output below 4000 rpm has been increased for greater drivability. The Civic Natural Gas has an EPA-estimated city/highway/combined fuel economy rating2 of 27/38/31 miles per gallon and is equipped with an automatic transmission as standard equipment. The Civic Natural Gas is the only OEM-built, dedicated CNG passenger car assembled# in America and the only vehicle certified by the EPA to meet both Federal Tier 2 Bin 2 and Inherently Low Emission Vehicle (ILEV) zero evaporative emission certification standards. The 2012 Civic Natural Gas will become available at the retail level in significantly more states than the current four (California, New York, Nevada and Utah) when it goes on sale in the fall. The increased availability of the Civic Natural Gas helps bring inherently clean-burning natural gas technology to an even broader audience while also supporting diversity in transportation energy resources.
