Chrysler Group announced that 13 Ram Truck dealers landed contracts with 19 states to supply their fleets with the new Ram 2500 Heavy Duty CNG pickup truck.

The successful Ram Truck dealers were announced by Oklahoma Gov. Mary Fallin and Colorado Gov. John Hickenlooper, who are leading a bipartisan group of 22 states seeking to use compressed natural gas (CNG) vehicles in their state automobile fleets.

The 13 Ram Truck dealers submitted formal bids in July in response to this multistate solicitation. The specific number of Ram 2500 Heavy Duty CNG pickup trucks being purchased in each state was not announced. The individual states now must finalize agreements with the dealers and issue purchase orders.

The multistate solicitation was designed to encourage auto manufacturers in the U.S. to develop more functional and affordable compressed natural gas vehicles and to encourage investment in public refueling infrastructure.

Earlier this year, both governors traveled to Detroit to meet with Chrysler Group and other automakers about the project. In July, the states issued a request for proposal soliciting bids for compressed natural gas sedans, pickups, and vans to be used in state fleets.

The Ram 2500 Heavy Duty CNG pickup is powered by the 5.7-liter Hemi V-8 and features both compressed gas storage tanks and a choice of 8- or 35-gallon gasoline fuel tanks. Redesigned cylinder heads with specifically designed CNG compatible valves and valve-seat materials allow the engine to burn both fuels. It also gets a second, CNG-specific fuel rail and set of injectors. New spark plugs improve combustion and durability, and a new powertrain control module allows the HEMI to seamlessly operate on either of the two fuel sources.

The Ram 2500 CNG system was fully engineered and tested by Chrysler Group and assembled at the company's Heavy Duty truck plant in Saltillo, Mexico.
