Special trucks switch from CNG to gasoline automatically when needed

Green is certainly in for Detroit automakers. “Green”, however, goes further than battery-powered EVs and hybrids for most brands. GMC and Chevrolet have announced that the Chevrolet Silverado and GMC Sierra full-size trucks will get a new option in late 2012 that will allow the vehicle to run both compressed natural gas and traditional gasoline.
The trucks will be able to seamlessly transition from compressed natural gas to the gasoline operation with no input from the driver. The engines in both trucks are the Vortec 6.0L V-8. With the combined CNG and gasoline fuel systems, the truck has a 650-mile driving range. Both GMC and Chevrolet will offer the trucks in standard and long bed with two-wheel drive or four-wheel drive options.
“The bi-fuel Chevy Silverado and GMC Sierra provide customers with choices in advanced propulsion technology, and because CNG is a clean-burning, domestically produced fuel, it has wide appeal, “said Ed Peper, general manager, GM Fleet and Commercial Operations. “ The addition of a full-size bi-fuel pickup truck to GM’s fleet portfolio is another milestone in putting the customer first in everything we do – by offering great products, innovative solutions and a great customer experience.”
GM notes that it is the only carmaker is able to offer a single source for gaseous fuel vehicles. The truck has its specially designed engine with fuel management system installed by Tier One. The supplier ships the truck directly to the customer when completed. The truck will also carry the standard GM three year, 36,000 mile limited warranty while the five-year, 100,000 mile limited powertrain warranty. The vehicles also meet EPA and CARB emission certifications.
“The bi-fuel truck provides businesses with added re-fueling flexibility and eases consumer range concerns that typically come with CNG, all while reducing emissions and controlling costs,” said Joyce Mattman, director, GM Commercial Product and Specialty Vehicles. “This turnkey ordering process, combined with the best warranty in the industry for a commercial product, makes our bi-fuel truck an attractive option, especially for commercial customers.”
