Which Terrain does Edmunds recommend?
Edmunds' Expert Review
Overall rating6.5 / 10
Although popular, the previous-generation Terrain was falling short of the class standards for drivability, technology and interior quality by the end of its run. Happily, the fully redesigned 2018 GMC Terrain addresses the problems the aging generation had and now represents a more compelling choice for a small, five-passenger crossover SUV.
The new Terrain pulls off the impressive trick of shrinking by just over 3 inches in length and 400 pounds in weight from the previous generation without sacrificing more than an inch of head- or legroom. Maximum cargo volume is nearly the same, too. That weight loss, combined with new engines and transmissions, promises better performance and fuel economy. However, the base engine struggles to deliver on its performance or fuel economy in the real world. We highly recommend the optional engine upgrades: The turbocharged 2.0-liter four-cylinder improves performance, while the turbocharged 1.6-liter turbodiesel is pleasant to drive and is a fuel economy champ — GMC estimates it will return 40 mpg on the highway.
The Terrain (and its sibling, the Chevy Equinox, which is nearly identical under the skin) is one of the nicest vehicles in the segment to spend time in. It's comfortable and easy to drive and comes standard with one of the best infotainment interfaces in the class. There's plenty of headroom all around, and the back seats fold flat with the pull of a lever. Aside from the disappointing base powertrain, downsides include a slightly smaller cargo area than some rival crossovers and pricing that's noticeably higher than other vehicles you might be cross-shopping. We also had to ding the Terrain for its overly firm ride quality.
If what you're looking for is efficiency, practicality and ease of use, the Honda CR-V with its 1.5-liter turbo engine is an obvious choice. The Mazda CX-5 provides a better driving experience and an interior that, in higher trims, feels even more upscale than the GMC's for less money. If you're looking for off-road prowess, the Jeep Cherokee and the Subaru Forester offer more capability.
2018 GMC Terrain configurations
Even the base SL trim of the 2018 Terrain comes with some desirable features, but it has a very limited options menu. Moving up to the SLE gets you access to more options. The SLT adds more luxury features and access to a few higher-end options. Finally, the top-trim Denali has features and options that put it in the near-luxury class, but it comes with a near-luxury price.
The base SL trim can only be had with the turbocharged 1.5-liter four-cylinder engine (170 hp, 203 lb-ft of torque) and a nine-speed automatic transmission, driving the front wheels. Trailering equipment is the only major optional upgrade available for the SL; beyond that it can't be upgraded. In fact, only three paint colors are available, and only white doesn't come with an added cost.
That said, the SL comes with a decent set of standard features, including keyless ignition and entry, cruise control, 17-inch alloy wheels, a leather-wrapped steering wheel, a rearview camera, two USB ports for the front seats, two charging-only USB ports for the rear, front and rear 110-volt power outlets, a 7-inch touchscreen infotainment system, Bluetooth, Apple CarPlay and Android Auto compatibility, and a six-speaker sound system with satellite radio. GM's Teen Driver system and OnStar are also standard.
The SLE trim comes with largely the same standard equipment as the SL, adding an auto-dimming rearview mirror, a compact spare tire and a handful of interior trim-piece upgrades. However, the SLE also gets access to a host of options and packages.
Packages include the Driver Convenience package, which adds a power-adjustable driver seat, heated front seats, dual-zone automatic climate control, roof rails and remote engine start. The Infotainment I package adds an 8-inch touchscreen, a navigation system, a color information display in the gauge cluster, an SD card reader, two extra USB ports in the center console box, and a 110-volt outlet for the rear seat. The Driver Alert I package adds heated mirrors, blind-spot monitoring, rear cross-traffic alert and rear parking sensors. Some of these add-ons can be had individually, along with a panoramic sunroof and trailering equipment.
Stepping up to the SLT trim gets you leather upholstery and the Driver Convenience and Infotainment I package (except for navigation). Upgrades for the SLT include the Driver Alert I package and the Driver Alert II package, which adds low-speed forward collision warning and mitigation with automatic braking, lane departure warning with lane keeping assist, and automatic high beams. The Infotainment II package adds navigation and a seven-speaker Bose stereo system. Also available is the Preferred package, which includes a power liftgate, driver-seat memory settings, a power passenger seat and a heated steering wheel.
Two gas engines are available for the Terrain. The 1.5-liter engine with front-wheel drive comes standard on both the SLE and SLT trims, but both can be optioned with either a more powerful gasoline engine or a more efficient diesel. The more powerful gas engine, a turbocharged 2.0-liter four-cylinder (252 hp, 260 lb-ft of torque), is available and comes with dual exhaust tips and larger wheels. Also available is a turbocharged 1.6-liter diesel-powered four-cylinder engine (137 hp, 240 lb-ft of torque), paired with a six-speed automatic transmission. GMC estimates the diesel will return 40 mpg highway. Equipping the diesel engine also adds the Driver Convenience package for the SLE and the Preferred package for the SLT.
All three engines come standard with front-wheel drive, but they can be optioned with all-wheel drive. A knob in AWD-equipped Terrains allows drivers to switch between all-wheel drive and front-wheel drive on the fly.
At the top of the Terrain range is the Denali, which can only be had with the 2.0-liter engine. The Denali receives unique styling cues and interior trim, as well as Denali-specific 19-inch wheels and LED headlights. It bundles in the Preferred package and Driver Alert I package, along with several other options such as the panoramic sunroof.
Optional extras for the Terrain Denali include the Driver Alert II package, along with the Advanced Safety package, which adds a surround-view parking camera system and an automated parking system. The Denali's Comfort package adds ventilated front seats and heated rear seats, as well as a wireless phone charging pad.

GMC Terrain vs. the competition
2018 GMC Terrain
2018 Honda CR-V
GMC Terrain vs. Honda CR-V
The 2018 Honda CR-V is the current class leader and for good reason. It benefits from a peppy yet efficient turbocharged engine, a large cargo capacity, roomy seating, a comfortable ride, confident handling and clever storage solutions. The GMC Terrain scores points with its upscale interior and infotainment system that is easier to use, but its higher price and smaller cargo area are notable drawbacks in comparison to the CR-V.
GMC Terrain vs. Chevrolet Equinox
The Terrain and Equinox are essentially the same vehicle underneath and share similar advantages and drawbacks. You'll get the same engine choices, nearly identical infotainment systems, same weak base engines, and smaller-than-average cargo capacity. Pricing is also similar, so the decision between the two will likely come down to personal preference and styling.
GMC Terrain vs. Hyundai Tucson
The Hyundai Tucson gets high marks for value with its feature-rich content at a more accessible price. You won't have as many engine choices as with the GMC, but the turbocharged option is similarly powerful and efficient. Neither Tucson nor Terrain has a particularly large cargo space, and both base engines are pretty disappointing for the class. The Hyundai isn't quite as refined on the inside, but it's still appropriate for the price.

Should I lease or buy a 2018 GMC Terrain?
Is it better to lease or buy a car? Ask most people and they'll probably tell you that car buying is the way to go. And from a financial perspective, it's true, provided you're willing to make higher monthly payments, pay off the loan in full and keep the car for a few years. Leasing, on the other hand, can be a less expensive option on a month-to-month basis. It's also good if you're someone who likes to drive a new car every three years or so.
