The range of most CNG vehicles is about half that of gasoline-fueled vehicles. The power, acceleration, payload and cruise speed of natural gas vehicles are comparable to equivalent internal combustion engines. CNG fleets report longer time between tune-ups, oil changes and engine rebuilds. Natural gas fuel tanks resist crashes and heat better than standard gasoline tanks. Since natural gas is lighter than air, it quickly spreads into the atmosphere if there is a spill or leak.
Natural gas has a narrower flammability range than gasoline.
In addition, American Honda will introduce its CNG-powered Civic GX Sedan in 1998. CNG and LNG buses and service vehicles are available from over 15 manufacturers. Heavy duty engine manufacturers including Detroit Diesel, Cummins, Navistar, John Deere and Hercules offer dedicated natural gas engines for many uses. Part of this cost may be deducted from federal taxable income.
