GM today announced that the 2013 Chevrolet Silverado 2500 HD and 2013 GMC Sierra 2500 HD pickup trucks will now be available with a bi-fuel system. GM's new bi-fuel system will allow the pickup trucks to operate on both conventional gasoline, and compressed natural gas (CNG).
Yes, the 2013 Chevy Silverado and GMC Sierra 2500 HD will be capable of operating on both compressed natural gas and good ol' pump gas -- though not at the same time. According to GM, the truck's 6.0-liter V-8 is capable of switching seamlessly between its CNG and gas fuel systems. That should help nip CNG range anxiety in the bud, as it allows owners to fill-up just about everywhere. GM expects the two trucks to have a range of over 650 miles when operating on both fuels.
Chevy and GMC will offer the Silverado and Sierra bi-fuel trucks with two bed lengths: standard and long. That's just as well because the diamond-plated CNG fuel tank will take up a bit of cargo room, since it's mounted in the Silverado or Sierra's bed. The CNG fuel tank is installed by a GM supplier, and fully-backed by a GM warranty.
GM says the Silverado and Sierra bi-fuel trucks will be available to commercial and fleet customers in rear- and four-wheel drive. The sole transmission option is GM's six-speed automatic. Power output on gas and CNG, expected fuel economy figures, and price are still to-be-determined.
