Why it stands out

The 2018 GMC Terrain stands out as a more premium take on the compact SUV formula, with distinct styling inside and out and a slightly higher price than its corporate cousin. GMC gave it features such as a push-button gear selector, better sound insulation, and a smarter interior, which helped it feel a bit more upscale than many rivals. It also offered a roomy cabin and a comfortable driving experience, making it appealing to buyers who wanted a practical small SUV without giving up a more polished feel.

Under the bonnet, the 2018 Terrain came standard with a 1.5-litre turbocharged engine producing 170 horsepower, while a 252-horsepower 2.0-litre turbocharged four-cylinder was optional with most models and standard with the top-shelf Denali trim level until it was discontinued for 2021. A nine-speed automatic came standard with both gasoline engines, and a unique 1.6-litre diesel engine was also offered in 2018 and 2019. That diesel was rated at 137 horsepower but delivered strong 240 lb-ft of torque and excellent fuel economy, making it the efficiency choice for shoppers who could find one.

There are trade-offs, though. The second-generation Terrain’s cargo space behind the rear seat trailed that of its most popular rivals, and some interior materials feel cheap. The 1.5-litre engine is sufficient for most driving tasks, but its highway acceleration isn’t very good, and the optional diesel is not easy to find on the used market. Even so, the 2018 Terrain remains attractive for buyers who value comfort, available features, and a more upscale presentation than many compact SUVs in its class.
