Honda was the first to sell a gasoline-electric "hybrid" car in the U.S. -- the Insight -- and earlier this year added the Civic Hybrid, first mass market hybrid model. The EPA has recognized the Civic GX natural gas vehicle, which went on sale in 1998, as having the cleanest internal combustion engine ever tested.
