While much focus has been placed on the 2017 Chevrolet Silverado HD family, let’s not forget about the 2017 GMC Sierra HD.
The Silverado’s fancier twin has also officially been SAE-certified to produce 445 hp and a whopping 910 lb-ft of torque from the 6.6-liter L5P Duramax turbo-diesel V8 engine. Big numbers, identical to the Silverado HD.
The 2017 Sierra HD was also introduced in Texas, although, not in as flashy of fashion as the 2017 Silverado HD. Chevy took to Texas Motor Speedway to set a Guinness World Record for World’s Largest Flag Pulled by a Moving Vehicle.
Continuing in Chevrolet and GMC’s twinning ways is a 19 percent increase in max torque over the old Duramax diesel engine, as well as the new air intake system complete with an exterior hood scoop. The new system not only provides cooler air to help the engine run better under heavy loads but also creates plenty of those extra ponies and units of twist.
The 2017 GMC Sierra HD will be available in regular, double cab and crew cab models, plus the Sierra Denali HD. If you’re looking for a tad more capability off road, the All Terrain HD will add 18-inch chrome aluminum wheels with all-terrain tires, Z71 suspension with Rancho twin-tube shocks and more.
The new Sierra HD will be available in early 2017.
