Honda Civic GX

The Honda Civic GX is a passenger car factory-built to run on compressed natural gas (CNG). The GX is a based on the Honda Civic and it is sold only in four U.S. markets, California, New York, Utah and Oklahoma. The GX is manufactured in Honda's Greensburg, Indiana plant together with the production of conventional Civics.

The Honda Civic GX first appeared in 1998 as a factory-modified Civic LX that had been designed to run exclusively on CNG (compressed natural gas). The car looks and drives just like a contemporary Honda Civic LX, but does not run on gasoline. In 2001, the Civic GX was rated the cleanest-burning internal combustion engine in the world by the EPA.

The GX was first leased to the City of Los Angeles to be used by parking enforcement officers and other city employees as a live beta test. The GX follows the same model year design changes as the Civic LX model, until the model year 2001 when a CVT (continuously variable transmission) was introduced in place of the 4 speed automatic transmission. In the 2006 year model, the GX again was equipped with the automatic 5 speed transmission, which increased its mileage and extended its range to 250 miles.

In 2005, Honda started offering the GX directly to the public through factory trained dealers certified to service the GX. Before that, only fleets were eligible to purchase a new Civic GX.

In 2006, the Civic went through its greatest modification since its inception. All variants of the Civic were awarded the 2006 Motor Trend "Car of the Year" award. The 8th generation Civic remains unchanged from 2006 and is also available in the GX model. The GX is a very limited-availability car with fewer than a thousand units per year being produced by the factory.

In October 2006, the 2007 Civic GX became available in New York, making it the second state where the consumer is able to buy the car.

Home refueling is available for the GX with the addition of the Phill Home Refueling Appliance. The Appliance is manufactured by FuelMaker, a Canadiancompany that markets the device in conjunction with American Honda. This allows owners of the Civic GX to refuel directly off of their home's natural gas supply when the car is not in use.

In April 2010 the GX became available to the public in Oklahoma. Honda chose this market thanks to low natural gas costs and state incentives.
