SLT All-Wheel Drive
2021 GMC Terrain
The 2021 GMC Terrain is a five-seat crossover with available all-wheel drive. Its sleek looks and contemporary design make it more of a family wagon than a rugged SUV. It's unchanged for 2021 other than the addition of blind-spot monitors as standard equipment. The Terrain is available with two engines, both turbocharged 4-cylinders, either a 1.5-liter version making 170 horsepower and 203 pound-feet of torque, or a 2.0-liter 252-hp turbo-4, both mated to a smooth 9-speed automatic transmission. As might be expected, acceleration is moderate with the 170-hp engine and steady with the bigger 252-hp engine.
The all-wheel-drive system requires the driver to engage the rear wheels for traction with the press of a button. The handling is crisp and the ride is tuned for the street, not trail.
The front-wheel-drive Terrain with the 1.5-liter turbo-4 earns EPA ratings of 26 mpg city, 30 highway, 27 combined, which drop to 25/28/26 mpg with all-wheel drive. The 2.0-liter models with all-wheel drive are rated at 21/26/23 mpg, or 22/28/24 mpg with front-wheel drive.
In safety, the NHTSA gives it five stars overall. Standard safety equipment includes automatic emergency braking and blind-spot monitors. Adaptive cruise control and a surround-view camera system are optional on the top two of four models.
