2020 GMC Sierra HD First Look, Review, Specs

The all-new 2020 GMC Sierra HD is coming to the dealerships later this year. After latest spy photos it is clear the whole Sierra HD’s lineup will get extensive exterior upgrades. The most significant changes will happen up front and the famous Denali trim will be available once again. This pickup truck will arrive in three different configurations and it will offer the same number of trim levels as before.

While the exterior slightly departs from the exterior of the current Chevy Silverado 2500 HD, mechanically, those two models are similar. The 2020 Sierra HD offers two V8 engines, gasoline, and a diesel. The new transmission is in the offer as well and it will be optional.

2020 GMC Sierra HD Includes Bolder Exterior

The forthcoming 2020 GMC Sierra HD will look similar to the current Chevy Silverado 2500 pickup truck. However, most of the styling cues are borrowed from the Sierra 1500 model. That includes bolder exterior features such as bumpers and the front grille. 20-inch wheels are also a carryover, along with the running boards.

Both 2500HD and 3500HD models will now offer more aluminum materials so the pickup will be lighter than before. Aerodynamics are better now and this heavy-duty lineup will wear more chrome details. The 2020 Sierra HD offers a MultiPro tailgate and CarbonPro box features. LED headlights are in the offer as well. Newest spy shots are showing new fog lights.
