Technology: It’s nice to see that every GMC Terrain comes standard with Apple CarPlay® and Android Auto™ smartphone integration, and even better that the touchscreen is so easy to use. It comes with USB ports, and that can be upgraded to six total in higher trims. The GMC comes standard with automatic emergency braking and forward collision alert, lane keeping departure warning and assist, and even automatic high beams. However, we suggest looking for models with the optional Pro Safety Plus package, which adds adaptive cruise control and blind-spot monitoring with rear cross-traffic alert.
Interior Comfort: If you’re a road tripper, the GMC Terrain interior is a comfortable place to spend time. The firm and supportive seats are good for the long haul, and the side cushions hold you in place without making it hard to get in or out. The low noise levels also contribute to overall comfort on road trips.
Cargo Flexibility: The Terrain doesn’t have quite the cargo capacity of some competitors, but it makes up for it with excellent flexibility. The hands-free power tailgate (SLT and up) is activated by sweeping your foot under the rear bumper. Inside, the flat-folding rear seatbacks are supplemented by a fold-flat front passenger seat to accommodate extra-long items, like a surfboard. It even has a hard plastic back to avoid damaging the upholstery.
Engine and Transmission: We’re not sure why GMC decided to drop the 2.0-liter engine that was previously available, but we sure wish they hadn’t. The remaining 1.5-liter just isn’t very powerful, and it’s connected to a transmission that needs some refinement. Unfortunately, there’s not even a benefit to fuel economy, with the Terrain trailing many in its class. If you want a smoother and more powerful setup, we suggest looking at 2020 and earlier Terrain models, which had the larger engine available.
