Silverado HD Models Now Available as CNG-Capable
The MY-2015 bi-fuel CNG Chevrolet 2500 HD.
Chevrolet has announced that its MY-2015 HD models will be available with a CNG-capable, bi-fuel 6.0L engine. The move gives fleet managers and consumers more options when choosing a 2500HD or 3500HD model, according to the automaker.
The compressed natural gas (CNG) option is available on all Silverado 2500HD configurations and Silverado 3500HD models with single rear wheels. The 2500HD double cab and crew cab models are on sale now, with 2500HD regular cab and all 3500HD models going on sale in July.
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. When equipped with a 4.10 axle ratio, the maximum conventional trailering rating is 13,000 pounds on gas or CNG.
GM warrants and validates the fuel systems of the 2015 Silverado HD bi-fuel trucks. GM’s 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. That’s not the case with some other manufacturers’ available bi-fuel trucks.
The 6.0L CNG-capable engine – identified by an LC8 engine code – features special hardened valves and valve seats that enable it to run on CNG 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.
A separate CNG fuel tank enables the driver to switch between fuels at the flip of a switch. When the CNG tank is depleted, the system automatically switches to gasoline. GM’s tier-one supplier installs the CNG fuel tank and complementing fuel system upgrades at a secondary location. Chevrolet dealers deliver the trucks as they would with any optional content.
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. The regular cab comes only in WT and LT trims. The new double cab model replaces the previous extended cab and features forward-hinged rear doors, which allow easier access to the back seat, especially in tight parking spaces.
The trucks are available with all-new, stronger 6-foot-6-inch and 8-foot cargo boxes with standard CornerStep bumpers, EZ Lift-and-Lower tailgates, and other features to ease cargo handling. Available updates for 2015 include:
- All new cabs and interiors with increased comfort and extensive storage space tailored to the way customers use full-size trucks.
- Chevrolet MyLink, which provides powerful connectivity for work or family with simple, intuitive controls.
- Integrated cruise control and Auto Grade Braking to help make trailering easier.
- Standard StabiliTrak with Trailer Sway Control on all models, including 3500HD duallys.
- 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.
Safety features such as Forward Collision Alert, Lane Departure Warning with an Active Safety Seat, and Front and Rear Park Assist are available on the 2015 Silverado HD. Head-curtain and seat-mounted side airbags are standard on 2500 models and available on 3500 models.
