Mercedes, which plans on displaying a natural gas-powered B-Class at the Washington Auto Show, has said it is interested in testing the U.S. market for the possible sale of a vehicle fueled by compressed natural gas. The clean burning fuel has been largely passed over by the American market as an alternative to gasoline-powered vehicles, with many automakers choosing to focus on hybrid vehicles instead.

Proponents of natural gas cite its availability, affordability, and environmental friendliness when urging the automotive industry to explore its energy options.

The Mercedes-Benz B-Class, which is sold in Europe, is an entry-level compact hatchback. Mercedes already sells a version of the B-Class that can run on gasoline or natural gas.
