General Motors has just announced that the CNG option is available on all Silverado 2500HD configurations and Silverado 3500HD models with single rear wheels. Both 2500HD double cab and crew cab models are on sale now, while the 2500HD regular cab and all 3500HD models will go on sale in July. With a separate CNG tank, the Silverado HD bi-fuel models have a total range of up to 650 miles.
The 2015 Chevrolet Silverado HD CNG is powered by a unique version of the 6.0-liter V8 engine (dubbed LC8), which is rated at 360 horsepower (268 kW) and 380 lb-ft of torque (515 Nm) on gas, and 301 horsepower (225 kW) and 333 lb-ft of torque (452 Nm) on CNG. A separate CNG fuel tank enables the driver to switch between fuels at the flip of a switch.
For those who don’t know, CNG is cleaner burning than conventional gasoline or diesel. Moreover, most of the natural gas used in the U.S. comes from domestic or other North American sources. According to General Motors, a CNG-powered truck that is driven for 26,000 miles per year can save over $2,000 if natural gas is used at least 75% of he time.
Silverado 2500HD and 3500HD models come in Work Truck (WT), LT and LTZ trims, and are offered in regular cab, double cab and crew cab configurations. Meanwhile, the regular cab comes only in WT and LT trims, while the new double cab model replaces the previous extended cab and features forward-hinged rear doors.
The trucks are available with all-new, stronger 6'6"and 8' cargo boxes with standard CornerStep bumpers, EZ Lift-and-Lower tailgates, and other features to ease cargo handling. Other updates for the 2015MY include increased comfort and extensive storage space tailored to the way customers use full-size trucks, Chevrolet MyLink, Integrated cruise control, Auto Grade Braking and StabiliTrak with Trailer Sway Control on all models.
Models equipped with CNG system add cargo tie-downs on the tank cover and a single fuel gauge that displays fuel levels for gasoline and CNG. In terms of safety, the 2015 Silverado HD comes with Forward Collision Alert, Lane Departure Warning with an Active Safety Seat, and Front and Rear Park Assist. Head-curtain and seat-mounted side airbags are standard on 2500 models and available on 3500 models.
