Compressed Natural Gas Vehicles

Compressed natural gas (CNG) vehicles are ideal for high-mileage, centrally fueled fleets, providing reduced emissions compared to gasoline and diesel fuels. They are used widely in the transportation industry for medium- and heavy-duty vehicle needs; however, no new, light-duty passenger CNG cars are currently on the market.


Typically, CNG cars produce fewer greenhouse gas emissions than gasoline cars, depending on the vehicle type and other circumstances. These reductions become more significant if renewable natural gas (RNG), or biomethane, is used in cars. RNG is essentially processed biogas, the product of the decomposition of organic matter that has been conditioned and upgraded to achieve higher methane content. Great strides are being made in reducing emissions from heavy-duty vehicles powered by CNG.

How They Work

Natural gas is a mixture of hydrocarbons consisting mainly of methane. Most of the natural gas consumed in the U.S. is domestically produced, reducing the nation's dependence on petroleum.


Currently, there are not any manufacturers making CNG passenger cars for consumers. Several companies are available to upfit certain car and pickup truck models to CNG, and these are represented in the CNG vehicle search. However, these upfit models are primarily larger, fleet vehicles.


Compressed natural gas cars have similar performance to their gasoline counterparts; however, they typically have a lower range between fill-ups.


No cost information for CNG passenger cars is available at this time as they are not currently being manufactured by automakers.


Limited incentives are available for CNG cars. Check out the incentives search to find incentives in your region.


Hundreds of CNG refueling stations exist in California. Fueling locations can be found using the California Natural Gas Vehicle Coalition Station Finder or the Department of Energy's Alternative Fuels Data Center map.
