Ram Truck announced it will be the only manufacturer in North America to offer a factory-built, compressed natural gas-powered (CNG) pickup truck. The Ram 2500 Heavy Duty CNG pickup, sold only to fleet and commercial customers, uses less expensive, less polluting fuel which is typically domestically sourced, reducing America’s dependence on foreign oil.
Allpar predicted the Hemi-based CNG system in September 2011. According to Allpar’s report, the CNG version adds 780 pounds to the weight of the vehicle. At the time, Ram chief Fred Diaz denied that Ram was making a CNG capable engine, which was true as far as production vehicles went but not as far as prototypes were concerned.
The Ram HD CNG has both compressed gas storage tanks and an 8-gallon gas tank. Canadian customers can opt for a 35-gallon gasoline tank. CNG-only range is estimated to be 255 miles, while the backup supply of gasoline extends the range to 367 total miles.
The Ram 2500 Heavy Duty CNG’s two 4.6 cu.-ft. (130-liter) CNG tanks are in the forward portion of the 8-foot pickup bed, mounted to the frame and covered by a painted 50 ksi high-strength steel cover. The CNG filler connection is next to the gasoline fuel neck.
The CNG tanks provide a gasoline gallon equivalent (GGE) of 18.2 gallons. A gasoline gallon equivalent of CNG is approximately 14.5 liters at 3600 psi. At current prices, which are generally $1.25 less than the gallon equivalent of gasoline, CNG promises significant cost savings over the life of the truck.
