2021 GMC Terrain SLT

The 2021 GMC Terrain is a compact SUV that slots between the smaller Chevrolet Equinox and the larger Acadia in GMC's lineup. It competes with the Honda CR-V, Toyota RAV4, and Ford Escape in the crowded compact crossover segment. The Terrain drives smoothly and quietly, with a composed ride that makes highway trips easy, though the engine can feel a bit strained when passing. Inside, the Terrain offers a straightforward cabin with comfortable seats, though rear visibility is hampered by thick pillars. The rear seats fold flat to open up generous cargo space, and the available hands-free liftgate adds convenience. Stepping up to the SLT from the SLE adds leather-appointed seats, a power liftgate, and the 8-inch infotainment screen with navigation. The 1.5L I4 makes 170 horsepower and sends power through the nine-speed automatic, which shifts smoothly but can feel a bit lazy in stop-and-go traffic. The SLT's available hands-free power liftgate is a real bonus when your arms are full of groceries.
