Chevrolet and GMC today announced details of General Motors’ bi-fuel 2013 Chevrolet Silverado and GMC Sierra 2500 HD extended cab pickup trucks at the NTEA Work Truck Show in Indianapolis, Indiana.
The vehicles include a compressed natural gas (CNG) capable Vortec 6.0L V8 engine that seamlessly transitions between CNG and gasoline fuel systems. The truck starts using gasoline and switches over to CNG once the proper operating temperature is reached However, the driver can switch between fuels at any time — even when driving at highway speeds — by pressing a button mounted on the dashboard. Combined, the trucks offer a range of more than 650 miles. The Silverado and Sierra will be available in standard and long box, with either two- or four-wheel drive.
The bi-fuel trucks are built with a specially designed engine. The fuel system is installed by GM’s Tier One supplier, and the completed vehicle is delivered directly to the customer.
