Chevy unveiled its 2015 Chevy Silverado HD CNG at the Chicago Auto show earlier today giving customers a new option for a cleaner-burning compressed natural gas vehicle.
There will be CNG versions available for all 2015 Chevy Silverado 2500 HD configurations and all 3500 HD models with single rear wheels. Estimates are that, with CNG currently running about 62 cents cheaper per gallon than gasoline, a truck driven 26,000 miles a year could see a cost savings of $2,000 with 75% CNG usage. The CNG equipped 2015 Chevy Silverado will also provide a longer driving range thanks to the separate CNG tank giving them a total range of up to 650 miles.
These vehicles will also feature a special version of the 6.0L engine that is labeled with an LC8 engine code for differentiation. These LC8 engines have been modified to run on either gas or CNG. Modifications include special hardened valves and valve seats. The engine will put out 360 horsepower with 380 lb-ft of torque while running on gasoline, or 301 horsepower and 333 lb-ft of torque while running on CNG.
Switching from gasoline to CNG is easy, requiring nothing more than the flip of a switch. If a vehicle using CNG runs through that fuel, then it will automatically switch over to the gasoline tank.
General Motors will offer a five-year/100,000-mile powertrain limited warranty on its CNG fuel systems. They’ll also cover major components of the CNG system which have GM service part numbers and will be available through their regular dealer network.
