2021 GMC Sierra 3500 HD: Changes, Upgrades, Specs, and Release. The forthcoming 2021 GMC Sierra 3500 HD will be released this year with some refreshments. Generally, the new model is getting numerous upgrades and plenty of changes. GM will borrow more cues from the Sierra 1500 model and share it with a 3500 HD model. Both models will provide a recognizable design language.
The new GMC Sierra will be equipped with more standard equipment than before. Like the predecessor, the 3500 heavy-duty truck will be available with three different cab configurations and four trim levels.
Under the hood of the newest 2021 GMC Sierra 3500 HD will be the same two powertrain options as before. We shouldn’t expect any changes. The stronger than ever 2021 GMC Sierra 3500 HD will be powered by a 6.6-liter gasoline V8 engine that generates 401 horses and 464 lb-ft of torque.
The next one is a 6.6-liter turbodiesel V8 engine and is available as optional. This turbodiesel V8 is able to deliver no less than 445 horsepower. The best part of this model is its torque. This model provides 910 lb-ft of torque. Thanks to that, the diesel model is a perfect choice for towing capabilities. Like before, the Sierra 3500 HD will be able to maximum tow 24,000 pounds. It also comes with hill start assist and back camera for an easy tow. Both powertrains above will use the same 6-speed automatic transmission that is smooth and easy to shift.
2021 GMC Sierra 3500 HD Design Look
The all-new 2021 GMC Sierra 3500 HD looks sturdy and reliable. It remains to be one of the aggressive and rugged models on the market. As we already wrote, most of the cues will be taken from the smaller Sierra 1500 pickup. Thanks to that, the new model will be more competitive. It includes numerous changes on the front fascia.
The front grille dominates and it looks wider. The manufacturer reshaped headlights and we like it more than on the previous model. Sides on this model will also host a new Corner Step system. 3500 HD will get more design boost thanks to nice-looking 18-inch wheels. Denali trim will once again dominate across trims. This trim package offers more luxury with additional chrome accents, and it adds the MultiPro tailgate system.
Inside, some changes will happen. The new 2021 GMC Sierra 3500 HD looks very modern and we can also say that this model is more comfortable. According to some rumors, most of the cues inside will be borrowed from the popular smaller Sierra 1500 model. As we all know, the interior of the 1500 mode is one of the best-in-segment. We can expect great techs and better materials. Don’t expect a new display because 2021 GMC Sierra 3500HD will only provide some modern optional amenities and a bigger list of standard features.
The Denali trim level is still the most wanted and the most expensive one. This version comes with a 15-inch head-up display, leather seats, and heated steering wheel. Basically, this is not all. The Denali will also be available with various wood and chrome accents. Thanks to that, it will provide more premium feel inside than the rest of the trims. Crew cab configuration is still the best choice that offers a room for six passengers.
