Honda Civic GX

The Honda Civic GX is a passenger car that has been created to run on CNG (Compressed Natural Gas).

History
The Civic GX first appeared in 1998 as a Civic LX that had been modified at the factory to run on CNG. The car looks and drives just like a Civic LX of the era but does not run on gasoline. The GX was first leased to the City of Los Angeles to be used by parking enforcement officers and other city employies as a live beta. The GX follows the same model year design changes of the LX model until the year 2001 when a CVT is used instead of the 4 speed automatic transmission. In 2005 Honda started offering the GX directly to the public through dealers certified to repair the GX. Before that, only fleets were eligible to purchase a GX new. The latest, 8th generation Civic is also available as a GX model.

Performance
The GX has a 1.6 through 1.8 liter inline four-cylinder engine. Performance is slightly less than an LX of the same model year. The CNG cylinder (fuel tank) holds 8.0 GGE (Gasoline Gallon Equivalent) at 3600 psi. Remember that CNG is a gas, not a liquid like gasoline. Range on a full 3600 psi fill is 200-250 miles depending on driving conditions and technique. The 2007 Honda Civic GX averages 28 MPG city and 39 MPG highway.
