2013 Chevrolet Silverado HD and GMC Sierra 2500 HD extended cab heavy-duty pickup trucks will have a bi-fuel option for $11,000 above the suggested base-vehicle price and you can order them now. The pickups, which run on compressed natural gas (CNG) and gasoline, have a Vortec 6.0L V8 engine that seamlessly transitions between the two fuel systems. A single light-weight Type 3 tank in the bed maximizes available payload and bed space, offering more usable space than competitors. The Silverado HD and Sierra 2500 HD offer customers fueling flexibility with a combined CNG and gasoline range of more than 650 miles.
