Honda Civic GX
Honda Civic GX
Overall mpg: 28 miles per gallon-equivalent of compressed natural gas
Est. annual fuel cost: $884
Lowest base price: $24,590
The Honda Civic GX runs on compressed natural gas, not gasoline (hence, the gallon-equivalent number).

Since you're unlikely to find a natural gas pump at your corner gas - as in gasoline - station, Honda also sells an at-home pump that taps into your home's natural gas line.

Plan your trip carefully if you go far from home, though. The Civic GX travels about 170 miles on a single fill-up.
