Why it stands out

The 2023 GMC Terrain stands out as a compact SUV that leans more premium than many of its rivals. It offers a roomy cabin, comfortable ride, and a useful set of standard safety and driver-assistance features, including adaptive cruise control, lane keep assist with lane departure warning, enhanced automatic emergency braking, front pedestrian and bicyclist braking, intersection automatic emergency braking, rear cross traffic braking, reverse automatic braking, side bicyclist alert, and blind zone steering assist. Families may also appreciate the Teen Driver system, which lets individual keys be programmed with speed limits and maximum audio levels.

For 2023, the Terrain’s standard powertrain was a 1.5-liter turbocharged engine with 175 horsepower and 203 lb-ft of torque. Front-wheel-drive models used a continuously variable automatic transmission and were rated at 26 mpg city, 28 mpg highway, and 27 mpg combined, while all-wheel-drive versions switched to an eight-speed automatic and returned 24 mpg city and 25 mpg combined. The 2023 model also had an upgraded trailer braking feature, though it did not increase towing capacity. Buyers who want more cargo room or stronger acceleration may find the Terrain less convincing, since cargo space is on the small side for the class and the 1.5-liter engine’s highway acceleration is not very good.

What makes the 2023 GMC Terrain appealing is the way it balances everyday comfort, a polished interior feel, and a long list of useful technology in a package that is often priced below some better-known competitors. It is not the most spacious or the most powerful compact SUV, but it can make sense for shoppers who value a comfortable, well-equipped small crossover with good reliability scores and a premium-leaning character.
