GMC 2021 Lineup: Models And Changes Overview

All-new EVs on the way for the Professional Grade brand.


  • The GMC Hummer EV pickup truck is the hero of GM’s upcoming electric vehicle onslaught.

  • GMC Yukon is all-new for the 2021 model year.

  • The Hummer EV SUV should be unveiled in February.


Given that passenger car sales are in a downward spiral, while crossovers and pickup trucks are gaining in popularity, it’s like the GMC brand was created from the start for this growing trend.

In addition, General Motors has revealed its electric vehicle strategy, and the star of that upcoming onslaught will wear a GMC badge, as will three other EV models. Here’s what to expect from the GMC brand in 2021.

By now, anyone mildly interested in cars already knows that the GMC Hummer EV pickup truck has recently been revealed. The Edition 1 trim level is the first one that will hit U.S. dealerships in the fall of 2021, and reservations for this range-topping model were filled in mere minutes. It will feature a three-motor powertrain with an expected 1,000 horsepower along with 11,500 pound-feet of wheel torque, good for 0-60 mph blasts of about three seconds. Unfortunately, Canada won’t get the Edition 1, which means the Hummer EV won’t arrive in the country before the end of 2022.

Next up will be the GMC Hummer EV SUV, which will share the pickup truck’s mechanicals and, most likely, the Crabwalk four-wheel steering system, the Extract Mode six-inch suspension lift and the Ultravision underbody camera system, among other things. Like the pickup, the SUV will offer three powertrains, including the 1,000-hp setup, but also a two-motor combo with 625 hp and 7,400 pound-feet of wheel torque, and a three-motor system with 800 hp and 9,500 pound-feet. The GMC Hummer EV SUV should make its official debut in February, probably during the Superbowl.

Another GMC EV pickup truck as well as an EV crossover will also be introduced within the next few years, and the automaker will likely give us a glimpse of these two new models over the course of 2021.

The brand’s best-selling model is obviously the GMC Sierra. A mid-cycle refresh is expected for the 2022 model-year Sierra 1500, which will feature styling enhancements, a revised interior design and Super Cruise driver assist, among other things. The 2021 model year won’t bring significant changes, as the Sierra 1500 continues to offer six powertrain choices and a multitude of trim levels and configurations.

The GMC Sierra HD was thoroughly redesigned for the 2020 model year, and few changes were made to the 2021 model. It’s available with regular cab, double cab and crew cab body styles in 2500HD and 3500HD series, and under the hood, we find a 6.6L gasoline V8 with 401 horsepower and 464 pound-feet of torque as well as a turbo-diesel 6.6L V8 with 445 hp and 910 pound-feet.

The 2021 GMC Yukon is all-new, riding on a new platform and boasting slightly increased dimensions on the outside, with significant gains in cargo space. It’s available once again in regular Yukon and extended-wheelbase Yukon XL configurations, while engine choices include a 355-horsepower 5.3L V8, a 420-horsepower 6.2L V8 and a 277-horsepower turbo-diesel 3.0L six.

The 2021 GMC Terrain loses its turbo 2.0L engine, so the only remaining powertrain choice is a turbocharged 1.5L four with 170 horsepower and 203 pound-feet of torque, matched to front-wheel or all-wheel drivetrains. The Denali trim level won’t be available for a while, but should return during the second half of 2021MY production. The Terrain also gets some option package changes and one less paint colour to choose from.

The 2021 GMC Acadia also receives option package changes, including a new Elevation Edition, along with three new paint colours and five deleted hues as well as new alloy wheel choices. Inside, the Acadia benefits from wireless Apple CarPlay and Android Auto integration in addition to various trim changes across most trim levels. The Acadia Denali is now available with the turbo 2.0L engine that develops 228 horsepower and 258 pound-feet of torque, in addition to the 3.6L V6 with 310 hp and 271 pound-feet. The base engine remains the 2.5L inline-four with 193 hp and 188 pound-feet.

The 2021 model year brings some styling enhancements to the GMC Canyon, including a new front fascia and redesigned alloy wheel choices. The base SL trim level is gone, while the Canyon and SLE trims become Elevation Standard and Elevation in a lineup that also rounds up SLT, AT4 and Denali. An Off-Road Performance Edition package has recently been introduced for the Canyon AT4, too. Powertrain choices are the 200-hp 2.5L four, the 308-hp 3.6L V6 and the 181-hp turbo-diesel 2.8L four.

Finally, the very old GMC Savana, which hit the market in its current form back in 1995, never changes much from one model year to another. However, for 2021, it swaps the old 6.0L V8 for a more modern 6.6L gasoline V8 with 401 horsepower. The base engine remains the 276-hp 4.3L V6, while the turbo-diesel 2.8L four with 181 horsepower has been around for a few years now as well. The Savana is still available in Cargo, Cutaway and Passenger variants.
