Production of the revised GMT 900 heavy-duty pickups has started this week at its Flint, Mich. facility. General Motors made significant upgrades on the 2011 Chevrolet Silverado HD and GMC Sierra HD models. The first unit made was a bright red, regular cab 2011 Silverado 2500 HD, with the revamped 6.6-liter Duramax turbo-diesel V-8.
This unit will be delivered to Strawberry Point, Iowa. The second unit is similar to the first, except that it's a crew cab. It's destined for Sumner, Washington.
The 2011 pickups got major upgrades to the frame as well as the diesel powertrain, making them more competitive against the latest (Dodge) Ram Heavy-Duty and Ford F-Series Super Duty pickups.
GM's trucks get additional payload and towing capability. A regular cab, two-wheel-drive, short-bed 2500 HD, when paired with the revised Duramax (which produces 397hp and 765 pound-feet of torque) is now able to tow 17,000 pounds.
This is about 1200 pounds more than the 2010 2500 HD models. The 3500 HD models offer even higher capabilities. A diesel, two-wheel-drive, 3500 HD dually crew cab is capable of pulling a fifth-wheel trailer that weighs up to 21,700 pounds.
This represents a 5200-pound improvement over the 2010 models. To aid in controlling these loads, the trucks are equipped with an engine brake, paired with upgraded 14-inch front and rear brake discs.
Production of the 2011 Chevrolet Silverado HD and GMC Sierra HD pickups are now in full-scale. Dealerships throughout the country will receive these models within the next several weeks.
