“With CNG capability to be offered on all Silverado HD cab configurations, customers have a wider range of choices when it comes to selecting the alternatively fueled truck that matches their needs,” said Ed Peper, U.S. vice president, General Motors Fleet and Commercial. “And for companies and municipalities that maintain multiple trucks in their fleet, the fuel cost savings of natural gas can really add up in a year – a work truck driven 26,000 miles a year can save more than $2,000 annually.”
The unique version of the 6.0L engine, identified by an LC8 engine code, features special hardened valves and valve seats that enable it to run on natural gas or gasoline. It is rated at 360 horsepower (268 kW) and 380 lb-ft of torque (515 Nm) on gasoline, and 301 horsepower (225 kW) and 333 lb-ft of torque (452 Nm) on CNG. With the additional driving range enabled by a separate CNG tank, Silverado HD bi-fuel models have a total range of up to 650 miles, meaning less time needed for fill-ups.
Moreover, GM warrants and validates the fuel systems of the 2015 Silverado HD bi-fuel trucks. The five-year/100,000-mile powertrain limited warranty covers CNG fuel systems. All major components associated with the CNG system also carry GM service part numbers, for availability throughout the largest dealer network in the United States.
