The arrival of the new generation of the Terrain crossover was a big hit. The company can feel it in increased sales. Now, the vehicle is again over 100,000 sold units per annum. Well, with recent changes still being fresh, we won’t see a large update in the next couple of years, until the mid-cycle facelift. The biggest thing coming for the 2021 GMC Terrain is the new Denali version.
The vehicle was spied, but we don’t have too many details about it. Besides the most luxurious package, the 2021 GMC Terrain will offer plenty of other options. There are other three trim levels available. Of course, there are also additional packages. Further choices are for the engine room. A couple of four-cylinder units are both turbocharged. We are still waiting to hear updates about a diesel and hybrid version.

The new 2021 GMC Terrain was caught on a couple of occasions. Test mules are showing the premium version of the crossover. Denali model comes with significant upgrades and probably a new infotainment system. Outside, this one is pretty much the same as the base version. Dimensions and shapes can’t tell you which model is behind camouflage. But, some details are characteristic of the high-end model.
For example, the premium package uses special wheels which are larger than on other trims. Also, LED lamps are standard, while the headlights are getting the C-shape. A lot of chrome details are there. Furthermore, the 2021 GMC Terrain Denali is going to get a premium audio by Bose, navigation and heating for both rows of seats. Many assist features are available and we will probably see the wireless charging as well.
2021 GMC Terrain Trim Levels
The cheapest version of the will be again the SL. With this package, buyers are getting Apple CarPlay and Android Auto, and PRO safety system. Emergency braking, forward collision alert, and few more features are part of this suite. The leather steering wheel and keyless start are standard. The center of the infotainment system is a 7-inch touchscreen display.
Moving up to the mid-range offer, the SLE is adding a larger driver info center. Instead of a 3.5-inch display, you will get a 4.2-inch screen. Also, the SLE package adds body-color mirror caps. Inside, there are special levers for folding the rear row and providing more cargo space.
Only the Denali package tops the offer of the SLT model. The 2021 GMC Terrain comes with 18-inch wheels and side rails, the most notable exterior upgrades. Inside, designers added dual-zone climate control, leather upholstery, heated front buckets, and a larger infotainment screen. Of course, the company prepares a few surprises for the new arrival.

2021 GMC Terrain Specs
Under the bonnet of the base 2021 GMC Terrain will be the same turbocharged engine. A 1.5-liter unit is good for 170 horsepower and 203 lb-ft of torque. It is the only source of power for the entry-level model, while it is not available for the Denali version. If you need more juice, check out the 2.0-liter version. This babe boosts the outputs to 250 hp and 260 lb-ft. Converted to miles per hour, it is 6.5 seconds for the 0-60 sprint. A power router is a nine-speed automatic, which sends energy to front wheels by default. Of course, the carmaker will also offer an all-wheel drive.
New Engines – Diesel and Hybrid
Previously, Terrain also used a V6 engine. However, the company dropped it because of the high fuel consumption. Now, General Motors is ready for the next step. There are two possible options for the compact crossover. The first one is a diesel unit. A 1.5-liter turbo-four is capable of producing 140 hp and 240 lb-ft of torque. The fuel economy jumps to 33 mpg. A petrol unit is good for 28 mpg combined.
According to rumors, GM is finally developing a hybrid unit for its compact crossovers, including the 2021 GMC Terrain and Chevy Equinox. While most rivals are already in the market with such electric systems, General Motors is a bit late. Still, a tough task is waiting for engineers. There are no doubts that new technology will boost the fuel economy, but can we see Terrain challenging leaders in this segment? Toyota Rav4 and Honda CR-V return 42 mpg. Also, there are a lot of other questions, regarding the base, petrol powerplant, and other upgrades that will make a hybrid competitive.

2021 GMC Terrain Release Date and Prices
Without big changes, we won’t wait for too long for the 2021 GMC Terrain. The version for the 2020 season is already available for purchase for some while. So, the new one will be ready for the last quarter of the year. The base crossover will cost around $26,000. The larger engine becomes an option at SLE trim and adds around $3,000. The premium Denali version is going to come with a $40k price tag.
