2020 GMC Sierra HD Concept: Specs and Release Date


After the recent introduction of the all-new 1500 series, it is time to see heavy-duty versions of the famous full-size truck. The new version is about to come as 2020 GMC Sierra HD. The Silverado’s sibling has been around for more than 25 years. For all this time, these two models were tightly connected.

In terms of mechanics, there are no differences, no matter the generation or version. On the other side, each model comes with its own appearance. The same case is with the new generation and the same case will be with the new 2020 Sierra HD, which is about to come next year.

Expect to see a familiar styling, though with numerous distinctive details, as well as various mechanical upgrades. On the other side, the engine lineup will probably remain the same as in the outgoing model.

2020 GMC Sierra HD Specs

In terms of base design characteristics, the new 2020 GMC Sierra HD is about to come with a lot of novelties. Of course, the base 1500 model will serve as the basis. Expect the same architecture, of course with further enhancements that will make the truck more capable. One of the most notable things about the generation is significant weight saving. In order to keep the pace with the toughest rival, F-Series, GM utilized a lot of modern lightweight materials, which saved some pounds but kept a high dose of rigidity. In terms of body styles, expect to see familiar layouts, which includes different cab designs, bed sizes etc.

2020 GMC Sierra HD Exterior

In terms of exterior design, the 2020 GMC Sierra HD will come with a lot of changes. It will come based on the light-duty model, which means a lot of changes compared to the outgoing model. While the overall shape is about to remain pretty much the same, there is a bunch of new details to come. Of course, we will see a completely new front end, adapted to the brand’s newest design language. Moreover, expect additional tweaks that will accentuate truck’s heavy-duty character. This would mean more massive grille and bumpers, bigger wheels, higher ground clearance etc.

Besides new styling, the rear end will also feature the company’s new Multi Pro Tailgate design. This feature brings a lot of benefits in when it comes to loads/unloads of large and heavy items. The testing model has been spotted for a few times so far. It still wears a camouflage but should take it off soon. After that, we will know all the details about the new 2020 GMC Sierra HD.

The cabin of 2020 GMC Sierra HD is another aspect of the truck where we expect to see a lot of changes. Speaking of the base design characteristics, we will see three familiar cab designs in the offer – Regular, Double and Crew. Each one will come with a new dashboard design, which is about to utilize a layout similar to the base 1500 model, though in a little bit more rugged manner. Expect better materials quality, as well as more tech features in the offer. When it comes to base equipment structure, things should remain the same. We should see four trim levels in the offer. Those are Sierra, SLE, SLT, and Denali. The last one is a famous top-range, luxury-oriented trim, which will once again come not only with more standard equipment but with plenty of unique visual details as well, both outside and inside the truck.

2020 GMC Sierra HD Engines

When it comes to 2020 GMC Sierra HD, it looks like the new model is about to come without bigger changes. We should see the same two units on the offer. Both of them are available already in the base Sierra trim level. The first one is a familiar 6.0-liter V8 gasoline engine, which has a max output of 360 horsepower and 380 pound-feet of torque. For those who care about fuel economy, the great thing about this engine is that it runs on natural gas as well. Still, the real deal with heavy-duty trucks come with diesel engines.

This model will continue with a familiar 6.6-liter V8 Turbodiesel unit. It is good for about 445 horsepower and 910 pound-feet of torque. Although there is no official confirmation yet, few reports suggest that both engines could come with smaller tweaks that will provide more power and better overall efficiency.

When it comes to transmission, both engines should continue with the same 6-speed automatic gearbox.
