As the name suggests, natural gas vehicles, is an alternative fuel vehicle generally referred to as NGV which uses compressed natural gas (CNG) or rarely liquefied natural gas (LNG) as a clean alternative opposing conventional automobile fuels like traditional gasoline and diesel.  Worldwide, as fuel prices are hiking more people are turning to NGVs and moreover the natural gas powered vehicles are all comparable with conventional fueled vehicles in regard with the travel speed, acceleration and horsepower. In addition natural gas is one of the cleanest, least polluting fuels.

Natural gas vehicles generates power which is approximately 1% lesser than that of gasoline. Nevertheless, its high octane rating enables elevated compression ratios in combustion engines which results into well-organized burning of the fuel eventually helps it combust slightly cleaner than standard gasoline combustion. On the other hand it also has a drawback when it comes to emissions as it produces slightly higher amounts of carbon monoxide gas than gasoline. But the emission of other gases from NGV is comparatively lower than that of gasoline.

Economical compressed natural gas (CNG) powered vehicles can have a direct and positive impact on the matters of air quality, and public health. For this, even existing gasoline-powered vehicles can be converted to permit the use of CNG. There are many car manufacturers who are producing cars that can run on CNG. Worldwide, there are more than 7 million NGVs running on the roads. Honda Vivic GX is the NGV commercially available in U.S market. Even prevalent use of natural gas-powered buses in public transportation has risen in

U.S, Australia, India, Argentina and Germany.
