The new Civic GX is powered by compressed natural gas—methane—the simplest and cleanest-burning hydrocarbon available. With an economical 113-hp, 1.8-Liter engine, the EPA has called the Civic the “world’s cleanest internal-combustion vehicle” with 90% cleaner emissions than the average gasoline-powered car on the road in 2004. Bear that natural gas can be purchased for $0.63 per gallon.At $24,590, buying a new Civic GX won’t exactly break your bank account, especially since up to $7,000 will come back to you in the form of state and federal tax credits. But don’t expect to find one easily. The car is only sold in two states, New York and California, and Honda can’t build them fast enough. One dealership said they have over 80 people waiting to buy.
It’s fairly obvious why densely populated states would be interested, especially since natural gas is a readily available source of heating fuel for many parts of the country. Most importantly, the Civic is the Eagle Scout of emissions certifications: it qualified for the California Air Resources Board’s Advanced Technology Partial Zero-Emission Vehicle (AT-PZEV) status, which means that it’s a Super-Ultra-Low-Emission Vehicle (SULEV) with zero-evaporative emissions. To qualify for AT-PZEV, the Civic must also carry a 15-year/150,000-mile warranty on emissions equipment. It also meets EPA’s strict Tier-2, Bin-2 and ILEV certification.
Despite getting the equivalent of a good but not quite amazing 36 MPG highway/24 MPG city, the American Council for an Energy-Efficient Economy (ACEEE) awarded the Civic the green ribbon as the greenest vehicle of 2008. That’s the fifth consecutive year it’s taken the top prize.
