Why it stands out

The 2025 GMC Terrain stands out as a compact SUV that leans into a more premium, tech-forward feel. It was redesigned for the 2025 model year with new styling, revisions to the powertrain lineup and a thoroughly upgraded interior. Standard equipment is notably rich for the class, including a 15-inch touchscreen with the latest GMC infotainment software and Google Built-in, plus an 11-inch digital driver information centre directly in front of the driver. Heated front seats, a heated steering wheel and LED headlamps are also standard, and GMC includes a broad set of safety technologies such as 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.

The Terrain also offers some useful flexibility. Front-wheel drive models use a continuously variable transmission, while all-wheel drive versions get an eight-speed automatic and additional drive modes, including AWD and Off-Road. The available packages add more convenience and upscale touches, such as leatherette seats, dual-zone climate control, a power liftgate, wireless charging and 19-inch machined aluminium wheels. There is also a Teen Driver system that lets individual keys be programmed with speed limits and maximum audio levels, which may appeal to families with younger drivers.

At the same time, the 2025 GMC Terrain has a few clear limitations. It is powered only by a 1.5-litre turbocharged engine, and GMC does not currently list a hybrid powertrain option. Cargo space is also on the small side for the compact crossover segment, with 844 litres behind the rear seats and up to 1,798 litres with them folded flat. Even so, the Terrain’s combination of upscale presentation, standard technology and broad safety content gives it a distinctive place among compact SUVs.
