GM to Introduce CNG-Powered Pickup Trucks
They still guzzle gas, just a different kind.
General Motors has announced plans to introduce bi-fuel-capable versions of its full-size pickup trucks that can run on either compressed natural gas (CNG) or gasoline. Sales begin at the end of 2012.
Both Chevrolet Silverado and GMC Sierra models will be available to commercial and fleet buyers, but the company has not yet specified if they will be based on the light or super duty versions of the trucks.
GM currently offers CNG versions of its full-size vans that are powered by 6.0-liter V8 engines, but they are not bi-fuel capable. The conversions are handled by Indiana-based supplier IMPCO Automotive, who will also be responsible for the pickup trucks, but sales are handled directly through GM. Drivers of the pickups will be able to switch between gasoline and CNG power at the press of a button.
