With the GMC Terrain being only three years into its latest generation, the 2021 Terrain will roll into showrooms as a carryover model. However, buyers will have another trim to choose from: a new AT4 option. Last year, GMC announced that they would be adding AT4 versions to all its models, and it’s now coming to the Terrain. The AT4 will be slotted just below the Denali.
Exterior design will remain the same as the current Terrain for the most part, but will gain a bolder design and innovative technology when equipped in the AT4 trim. With this option, buyers can expect a more rugged exterior that includes a black chrome grille and fog light casings.
On the inside, expect much of the same as the current Terrain, which boasts a clean, sleek design and funky gear selector. It will come standard with a 7-inch touch screen and Apple CarPlay and Android Auto capability. Those who opt for the AT4 can expect trim-specific interior designs that sport aluminum details and premium fabric colors.
Under the hood, we expect no changes in powertrain offerings. The current Terrain has two engine options: a 1.5-liter turbo 4-cylinder that puts out 170 horsepower and 203 lb-ft of torque, and a 2.0-liter turbo 4-cylinder that offers 252 horsepower and 260 lb-ft of torque. The turbo-diesel option was dropped for the 2020 model year. Both engines are available with a nine-speed automatic transmission and standard rear-wheel drive, with all-wheel drive optional on SLE and above trims. The new AT4 trim will most likely receive the more powerful 2.0L Turbo engine and standard AWD.
All Terrains come standard with GMC Pro Safety which includes automatic emergency braking, lane keep assist, lane departure warning, forward collision warning, and more. Additional safety equipment such as adaptive cruise control, blind-spot monitors, and rear cross-traffic alert require an additional package or opting for the top of the line Denali.
