The 2015 GMC Terrain received an available 4G LTE Wi-Fi hotspot, the only noteworthy change for this compact SUV, whose comfortable interior, smooth ride and powerful V6 engine remain strengths to this day. Wi-Fi hotspots require a data plan to activate and may also require a compatible device. See the owner's manual or manufacturer website for more information.
If fuel economy is a priority the standard 2.4-liter four-cylinder gets the job done, but the available 3.6-liter V6 engine, which is powerful enough to outpace even modern compact SUVs, is hard to resist. The rear seats stand out in the quiet and comfortable interior thanks to the 8-inches they can move forward and backward. The dozens of infotainment and climate control buttons on the dash make the Terrain look dated, but might be preferable if you don’t like touchscreens.
It’s not realistic to expect modern tech like smartphone integration on a vehicle from 2015, but SLE-2 and higher trims feel a bit more modern thanks to Bluetooth® streaming audio in addition to the standard USB audio input. Available driver assist tech includes forward-collision warning and lane-departure alert, with blind-spot monitoring and rear cross-traffic alert exclusive to the Denali trim.

V6 Power: The powerful V6 engine available in the 2015 GMC Terrain manages to outpace even newer compact SUVs, thanks to its 301 horsepower. It can also tow up to 3,500 pounds when properly equipped, which is quite good for this class.
Rear Seat Flexibility: The sliding rear seat remains a strength of the GMC Terrain to this day. When the sliding seat is in its rearmost position, it actually has more rear seat room than its successor (2018-present). Slide it all the way forward, and cargo space is a bit better than newer Terrains, too.
Interior Comfort: The GMC Terrain’s comfortable and quiet interior remains unperturbed by rough surfaces, gliding over them seamlessly. The Terrain Denali is even smoother, befitting its luxury-level status.
Interior Controls: First introduced for the 2010 model year, by 2015 the Terrain was getting on in years, as evidenced by its confusing climate control and infotainment interface. The small touchscreen is a long reach from the driver, and the dozens of physical buttons below it look and feel alike, making them hard to use without taking your eyes off the road. You can look at contemporary rivals for better solutions.
