Natural gas engines are currently being engineered and offered by leading engine manufacturers such as Caterpillar, Cummins Westport, John Deere, Mack, and many others. Thanks to their ingenuity and expertise, a full range of natural gas powered engines are now available.

Many natural gas engines rival diesel in both performance and fuel economy. But natural gas engines also offer the added benefits of dramatically lowered emissions and ease of maintenance. With continued engineering advancements in natural gas engines, increasing numbers of light-, medium- and heavy-duty vehicles can access the economic and health benefits of vehicular natural gas.

With the rising cost of petroleum-based gasoline and diesel fuel, tougher emission standards and the growing public demand for better environmental policies, natural gas vehicles provide an attractive alternative with
a multitude of key advantages.
