Honda Civic GX

The Honda Civic GX is the only car factory-built to run on compressed natural gas in the United States that is available to non-fleet customers. It was based on the Honda Civic and was available for fleet sales in all 50 states, and was previously available for retail sale in four states, California, New York, Utah and Oklahoma, before being made available to retail consumers in 35 states. From late 2009 the GX was manufactured at Honda's Greensburg, Indiana plant together with conventional Civics, having previously been produced in East Liberty, Ohio. The third-generation GX was awarded the 2012 Green Car of the Year by the Green Car Journal in November 2011 at the Los Angeles Auto Show, and for eight years up to 2011 it was rated first by the American Council for an Energy-Efficient Economy in its Greenest Vehicle of the Year list.
