What's New in the 2018 GMC Terrain?

The Terrain was completely redesigned for 2018.See the 2018 GMC Terrain models for sale near you

Which Terrain is the Best?

We would recommend the SLT, as you get the same equipment as an SLE with options, but with leather upholstery and bigger wheels. Opting for the Driver Alert Package II is furthermore recommended. In terms of engine, either of the gas engines would be fine given your performance and fuel economy preferences. We'd skip the diesel engine.

How Much Does a 2018 GMC Terrain Cost?

The 2018 Terrain is available in SL, SLE, SLT and Denali trim levels.

The base SL ($25,000) comes only with front-wheel drive and the base 1.5-liter engine along with 17-inch wheels, automatic HID headlights, LED running lights, privacy glass, heated mirrors, passive entry and push-button start, active noise cancelation, a backup camera, height-adjustable front seats, a 60/40-split folding and reclining back seat, a leather-wrapped steering wheel, cloth upholstery, OnStar emergency communications and remote services, a 7-in touchscreen, Apple CarPlay, Android Auto, four USB ports (including one Type-C) and a 6-speaker sound system with an auxiliary audio jack and a media player interface.

The SLE ($27,900) is available with any engine as well as all-wheel drive. It adds as standard equipment a spare tire, an auto-dimming rearview mirror and levers in the cargo area that fold the back seat. Not a lot for an extra $2,900, but it does open the door to options. The Driver Convenience package (included with the SLE Diesel), adds remote ignition, a power lift gate, roof rails, dual-zone automatic climate control, heated front seats and an 8-way power driver seat with lumbar adjustment. To that package, you can add the Infotainment Package I, which includes an enhanced gauge cluster, an additional standard-type USB port, a 110-volt house-style outlet, an 8-in touchscreen, an SD card reader and satellite radio.

The SLT ($31,400) includes the Driver Convenience and Infotainment package items plus 18-in wheels, fog lamps, auto-dimming exterior mirrors and leather upholstery. Its Infotainment Package II adds integrated navigation, HD Radio and a 7-speaker Bose sound system. Its Preferred package (included on the SLT Diesel) adds a hands-free power lift gate, driver-memory functions, a 6-way power passenger seat and a heated steering wheel.

Optional on the SLE and SLT trims, and standard on the Denali is Driver Alert Package I that adds blind-spot and rear cross-traffic warning systems, rear parking sensors and the Safety Alert Seat.

The Denali ($37,600) comes only with the 2.0-liter engine and includes all of the SLT's optional equipment. It also adds ritzier styling details, 19-in wheels, upgraded interior materials and LED headlights. Optional only on the Denali is the Advanced Safety package that adds a surround-view parking camera and an automatic parking system. The Comfort package adds ventilated front seats, heated rear seats and wireless smartphone charging.

Optional on the SLT and Denali is the Driver Alert Package II that adds forward-collision warning, low-speed automatic emergency braking, lane-keeping assistance and automatic highbeams. Optional on all but the base trim is a panoramic sunroof.

2018 GMC Terrain vs the competition

2018 Honda CR-V -- Arguably the benchmark in the segment. It provides unmatched interior space and versatility, ample features for the money, strong performance and fuel economy and a nicely balanced driving experience.

2018 Mazda CX-5 -- The CX-5 stands out with its sport handling, sophisticated ride, luxurious interior and snazzy styling. It's definitely worth a long look.

2018 Chevrolet Equinox -- If you like what you're reading about the Terrain, but would prefer a different look, the Equinox is mechanically related to the Terrain. It has many of the same pros and cons, minus the Terrain's electronic shifter.

Used Jeep Grand Cherokee -- If you're looking for an SUV with more rugged capabilities and a fancier interior (and especially if you're seeking a diesel engine), the Grand Cherokee is a superb choice. It costs considerably more, though, so seeking a used model is recommended.
