General Motors says the 2014 Chevrolet Silverado 2500 HD and GMC Sierra 2500 HD compressed natural gas (CNG) bi-fuel pickup trucks will be available exclusively in a crew-cab configuration.
The crew cab models are available with a standard or long box and with two- or four-wheel drive. The vehicles have been designed to maximize both the number of passengers and the amount of bed space.
Fleet owners and retail customers can order GM's $11,000 EPA- and CARB-certified CNG bi-fuel option directly at Chevy and GMC dealerships, and the trucks are still covered by GM's three-year/36,000-mile limited warranty and five-year/100,000-mile limited powertrain and emissions warranty.
IMPCO Technologies Inc. performs the bi-fuel conversions on the 6.0-liter Vortec V8 engine with GM's gaseous-prep package. A single Type 3 CNG tank is installed in the truck bed, yielding a vehicle range of 650 miles when used in combination with the gasoline on board.
