2021 GMC Sierra 2500HD: Interior Changes, Diesel, AT4

It is big, it is mean, and the 2021 GMC Sierra 2500HD is back again. The robust heavy-duty model will hit the markets later next year, this time with minor changes. As you probably know, the 2020 model was completely redesigned. Knowing that new Sierra HD will receive very subtle cosmetic upgrades.

However, Sierra 1500 and Silverado 1500 models will get serious interior changes. The 2500HD could follow the same path or just a little bit. In terms of performances, nothing will change. General Motors offers a wide range of engines and trim levels. Whatsoever, the off-road capable AT4 variant is available as well.

ProGrade Trailering System

The model that will arrive in the coming weeks is redesigned, and it will get improvements in terms of performance. Unfortunately, the 2021 GMC Sierra 2500HD will mostly remain. The next model will arrive with very subtle and barely visible changes. On the other hand, this truck will stay robust and practical. Practicality is one of the strongest points. Despite its size, the Sierra HD offers a longer wheelbase than its predecessor.

Driving the heavy-duty model without a load is manageable. Whatsoever, even loaded truck is now much more comfortable to drive. The credit goes to the ProGrade trailering system. This system offers 15 different views of the truck and trailer. It helps with driving and parking. On top of that, it is safer, especially for the beginners.

2021 Sierra 2500HD Interior Refreshments

To this date, interior design wasn’t the strongest point of the Sierra HD models. Chevy Silverado can relate too. Now, the approaching 2021 GMC Sierra 2500HD will get a couple of big changes. The interior is relatively fresh, so don’t expect new features. General Motors plans to improve Sierra 1500 and Silverado 1500 light-duty pickups.

The heavy-duty lineup could follow the same path. The General Motors will provide upgrades such as reshaped center console and larger storage bins. On top of that, we expect more high-quality materials and more driver-assistance features.

Powerful Diesel Engine

The upcoming 2021 GMC Sierra 2500HD truck will continue to roll with the same engine lineup. The customers can choose between gasoline and diesel variants. A 6.0-liter V8 gasoline engine is available as a standard powertrain option. It delivers 330 hp and 380 lb-ft of torque. Moreover, it comes with a 9-speed automatic gearbox.

However, the highlight of the Sierra’s HD lineup is its potent 6.6-liter V8 Duramax. A diesel engine can generate 445 horsepower and up to 910 lb-ft of torque. Thanks to such influential figures, the 2500HD is a very competitive truck. Diesel version offers a 10-speed automatic transmission. All those figures will largely remain for 2021.

Off-Road Capable AT4 Version

All of the GMC’s pickups and trucks are offering the AT4 variant. The all-new 2021 GMC Sierra 2500HD is no different. The AT4 is off-road capable model that comes with the unique exterior design. On top of that, the interior is also distinctive.

The crucial difference is surely its off-road suspension and rear locking differential. The Sierra 2500HD AT4 comes with the standard skid plates and numerous driver-assistance aids. That includes the hill descent control, the hill start assist and the traction control.

2021 GMC Sierra 2500HD Price and Release Date

The price of the next 2021 GMC Sierra 2500HD truck will start at $36,500. On the other hand, the range-topping Denali trim level costs around $62,000. Latest GMC’s heavy-duty lineup will hit the dealerships in the last quarter of 2020. Before that, we are waiting for the 2020 Sierra 2500HD to come out.
