2021 GMC Acadia

This mid-size crossover has received an update recently and now comes more competitive in several aspects. As it is still a relatively new model on the market (introduced in 2017), the focus was on styling changes. Still, there are some other interesting changes, including a new engine option. All this clearly indicates that the 2021 GMC Acadia will come without more important changes.

We count on a familiar layout, characterized by a quite bold front and a nice-looking cabin. Also, the list of standard equipment is quite long, as well as the engine lineup. Considering all these things, we believe that the next-year model will be quite competitive in the segment where you can find some pretty big and popular names, including Toyota Highlander, Ford Explorer, Honda Pilot etc.

Given the fact that there are no bigger changes to come, we presume that the 2021 GMC Acadia will come in a typical time of year, sometime in the last quarter of 2020.

2021 GMC Acadia Design

The recent update has brought a lot of changes, but the overall layout is still the same. We are talking about the same crossover that rides on a familiar C1 platform. Still, keep in mind that it rides on a standard version of this architecture, not the stretched one you can find in models like Chevy Traverse and Buick Enclave. This one measures around 112.5 inches between the axles, which means 2021 GMC Acadia dimensions will ensure a good balance between comfort and maneuverability.

In terms of the styling, the recent update has brought a couple of very interesting changes. Of course, the most prominent are those at the front, where you can find a new grille and headlights, which are bold and heavily inspired by the new Sierra pickup truck. Also, keep in mind that there are versions with distinctive styling details. We are pretty sure that both 2021 GMC Acadia Denali and the off-road 2021 GMC Acadia AT4 will continue without more important changes.


When it comes to interior design, the recent update didn’t bring any particular changes. The overall cabin layout is pretty much the same, though there is an update infotainment system, with smartphone integration and a bigger 8-inch touchscreen, which is standard in all models.

Therefore, the upcoming model will continue in the same way, which means you may count on an upscale cabin, full of soft-touch materials and, generally, very good overall quality. Given the model’s size, you can count on a relatively spacious and comfortable cabin, thought the third row is typically tight for the class.

When it comes to 2021 GMC Acadia cargo space, count on familiar figures. This would mean around 13 cubic feet behind the third row and 79 cubic feet of overall cargo space.


When it comes to standard equipment, all models come with a new 8-inch touchscreen, as well as with Android Auto and Apple CarPlay. OnStar with onboard Wi-Fi also a part of standard equipment. Generally, most tech goodies are standard in base models, while upgrades are mostly in terms of comfort and convenience. In higher trims, you get things like leather upholstery, power-adjustable seats, heated and ventilates seats and steering wheel and more.

When it comes to safety, a lot of things have been added to the list of standard equipment. Some of the highlights are lane change alert, front pedestrian braking, rear cross-traffic alert, a safety alert driver’s seat, forward collision warning, forward automatic braking, front and rear parking sensors etc. Unfortunately, things like surround-view camera and adaptive cruise controls are available only in the range-topping Denali trim.

2021 GMC Acadia Engine

WE count on three familiar engine options to carry on in the 2021 GMC Acadia. Of course, base models should feature a 2.5-liter four-cylinder unit, which is good for about 193 horsepower and 188 pound-feet of torque. Also, there is a recently-introduced 2.0-liter turbo-four, which delivers around 230 horsepower and 258 pound-feet of torque.

Finally, there is a well-known 3.6-liter V6, which is good for about 310 horsepower and 271 pound-feet of torque. All models come paired with a six-speed automatic transmission.

When it comes to fuel economy, the base four-cylinder engine returns around 21 mpg in the city and 26 mpg on the highway. The V6 returns around 18 mpg in the city and 25 mpg on the highway. These are pretty typical ratings for the class. On the other side, numbers for the turbo-four are yet to come.

2021 GMC Acadia Release Date and Price

Considering that we won’t see bigger changes in the 2021 GMC Acadia, we presume it will hit the market sometime in the last quarter of the next year. The current model starts at around 29.800 dollars and we don’t expect bigger changes in the future.
