In the ongoing battle in Green Valley below Truck Mountain, Chevrolet has unleashed a CNG conversion kit for both 2500 and 3500 variants of the 2015 Silverado HD.
The kit allows the Silverado HD to run either compressed natural gas or gasoline at the flick of a switch, with the 6-liter V8 under the bonnet pumping out 301 horsepower and 333 lb-ft torque on CNG, or 360 horses and 380 lb-ft on gasoline. Range is expected to reach 650 miles through the use of both fuels, while towing capacity remains at 13,000 pounds.
For operators of work-duty Silveradoes, the CNG conversion would save $2,000 annually on fuel costs for a truck that does 26,000 miles using CNG 75 percent of the time, due mainly to the lower per gallon cost of CNG over a gallon of gasoline.
The kit — made for use in single-wheel setups only — is available now on 2500HD double cab and crew cab models, while 2500HD single cab and all 3500HD styles will be available in July.
