Bi-fuel 2013 Chevrolet Silverado, GMC Sierra heavy-duty pickups to run on ... - ConsumerReports.org
General Motors announced today that it will begin taking orders for new bi-fuel compressed natural gas (CNG) versions of its ¾-ton Chevrolet Silverado and GMC Sierra pickups. The trucks have a large compressed natural gas tank in the bed that looks like a large toolbox. 0-liter V8 engine can be switched from running on CNG to gasoline and back via a switch on the dashboard. The CNG Sierra and Silverado will be only be available in extended-cab 2500 HD form, with either a long or short bed and two- or four-wheel drive. Compared with gasoline, CNG typically produces much cleaner emissions while providing similar fuel economy, performance, and driveability. Its relative energy cost can be much less than gasoline when using a convenient home-fueling station. On the other hand, CNG vehicles have traditionally been priced thousands of dollars higher than a similar gasoline-powered version, public refueling stations are relatively rare, and CNG is not available at all—even for home fueling—in some areas. Pricing for the CNG Sierra and Silverado has not yet been set, but customers will be able to order the CNG package starting April. Source: www.consumerreports.org
