2013 Bi-Fuel Trucks Built in Indiana, Upfitted by Impco There

Production of the 2013 Chevrolet Silverado HD and GMC Sierra 2500 HD bi-fuel CNG pickup trucks is underway in Fort Wayne, Ind., General Motors said late last week, announcing that the vehicles are available for order by fleet and retail customers through Chevrolet and GMC dealers.

GM has commenced production of its 2013 Chevrolet Silverado HD and GMC Sierra 2500 HD bi-fuel pickup trucks Fort Wayne, Ind. CNG systems are installed by Impco Automotive in Union City, Ind.

The trucks are converted to bi-fuel CNG-gasoline operation by Impco Automotive in Union City, Ind. Impco uses a single, Type III, carbon fiber-on-aluminum, 17 gasoline gallon equivalent fuel cylinder by Worthington-SCI (Structural Composites Industries).

The GM pickups feature a single Type III, carbon fiber-on-aluminum, 17-GGE CNG tank by Worthington-SCI in a robust enclosure in the truck bed — ‘€˜designed to retain more bed space than any other OEM bi-fuel truck.’

The Impco gaseous fuel system meets GM quality, durability and safety standards, the automaker says, and the vehicles carry a three-year, 36,000-mile new vehicle limited warranty and five-year, 100,000-mile limited powertrain and vehicle emissions warranty. They meet U.S. EPA and California Air Resources Board emission certification requirements, GM says.

The bi-fuel option is priced at $11,000 above the suggested retail price of the base vehicle. The pickups are available in standard and long-box and two-or-four wheel drive in the extended cab models.

The Silverado and Sierra 2500 pickups have GM’s Vortec brand 6.0-liter V-8 engines. The Impco system “seamlessly switches between the two fuels without affecting performance,” GM says. Combined range of 650 miles, “the longest standard bi-fuel range of any original equipment automaker.”

“Customers are choosing our bi-fuel trucks because they provide the same high level of GM truck performance and versatility but can also help businesses control their fuel costs and reduce their carbon footprint,” GM U.S. vice president of fleet and commercial sales Ed Peper said in a release.

“At Chesapeake, we are converting our fleet of more than 5,000 vehicles to run on natural gas, and having options from GMC and Chevy is critical to help us reach our conversion goal,” Chesapeake Energy fleet operations director Nate Pumphrey says in the GM release.

“Following our full conversion, we will save $11 million to $12 million annually on fuel costs,” Pumphrey said.

The bi-fuel pickups are ordered from the factory, sent to the Tier One supplier Impco for installation of the CNG bi-fuel delivery and storage system, and delivered by GM transportation to the dealer or to an upfitter for customer-ordered modifications.
