Why it stands out

The 2020 GMC Terrain stands out as a compact SUV that leans more premium than many of its rivals. GMC positioned it as the more upscale alternative to the Chevrolet Equinox, with distinct styling inside and out, a push-button gear selector, better sound insulation, and a slightly smarter interior. For buyers who want a small SUV that feels a bit more polished, that combination gives the Terrain a clear identity.

For 2020, the Terrain lineup was updated and important safety technology became standard, including automatic emergency braking, forward collision alert with pedestrian detection, lane keep assist, lane departure warning, and automatic high beams. The diesel engine was dropped that year, and the Denali received an upgraded suspension package to improve its ride and handling. The 2020 GMC Terrain Denali is especially notable because it was the only version that paired the more powerful 252-horsepower engine with that improved suspension package.

There are still trade-offs to consider. The Terrain’s cargo capacity is on the small side for the compact crossover segment, and the 1.5-litre turbocharged engine is described as sufficient for most driving tasks but not especially strong on the highway. Even so, the 2020 GMC Terrain can be appealing to shoppers who value comfort, a roomy cabin, good safety equipment, and a more upscale feel than many compact SUVs in its class.
