  • Optional engines offer efficiency and power
  • MyLink user interface is intuitive and easy to use
  • Extensive list of optional safety features

Which Terrain does Edmunds recommend?

We think the SLE with the Driver Alert I package gets you all the basic safety and technology features you need, plus quite a few you'll want. However, buyers who want a full suite of active safety features, including forward collision mitigation with automatic braking and lane departure intervention, will need to upgrade to the SLT and the Driver Alert II package. In either case, we also recommend upgrading from the base engine, as the 2.0-liter dramatically improves the driving experience without a serious mileage penalty.

Edmunds' Expert Review

Overall rating

6.5 / 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.

Trim tested

Each vehicle typically comes in multiple versions that are fundamentally similar. The ratings in this review are based on our full test of the GMC Terrain SLT (turbo 1.5L inline-4 | 9-speed automatic | FWD).


The base engine lacks power, the transmission is slow-witted, and the powertrain's focus on fuel economy all but eliminates snappy acceleration and quick pedal response. Elsewhere it's better. The brakes feel good, and though it's no sport SUV, the Terrain handles curves and corners with composure.


The small turbocharged engine delivers decent zip at low speeds, but acceleration falls off as the transmission runs for its highest gears to save fuel. Good in theory, but awful when trying to merge or pass. Our as-tested 0-60 mph time was 9.3 seconds, highlighting the Terrain's leaden pace.


The brakes bite smoothly and evenly, with a good relationship between pedal pressure and actual stopping power. Initially the pedal feels a little soft but firms up after a few millimeters of travel. The Terrain stopped from 60 mph in 126 feet in our testing, a decent result for a compact SUV.


The steering is slow, making for a lot of mush to steer through before the Terrain starts to change direction in earnest. The steering effort weights up nicely at highway speeds, imparting more confidence and a sense of stability.


Capable and balanced on twisty roads, the Terrain keeps body roll in check. You won't mistake it for a Mazda CX-5, Ford Escape or other sportier rival; it lacks the necessary suspension tuning or tire grip. But through turns at reasonably high speeds, the Terrain remains stable and composed.


Good braking and competent handling can't make up for a weak engine and languid transmission. When you need immediate speed, the accelerator often feels mushy and lifeless, while engine speed and downshifts exhibit noticeable lag and delay. Doesn't inspire confidence when highway merging or passing.


Poorly placed central air vents and stifling leather upholstery aside, the Terrain is quite comfortable, at least at rest. On the road, it's prone to regular low-impact shock, vibration and jostling on even moderately rough road. The seats are good, though, and the cabin keeps outside noise at bay.

Seat comfort

The firm but not rigid seats are comfortable overall and hold up well over long miles. But they're somewhat compact; bigger and broader passengers might find them constricting. Bolsters are relatively flat and low, seatbacks a bit narrow. Rear seats are comfortable, but cushions are somewhat flat.

Ride comfort

This Terrain rides surprisingly poorly on regular pavement. Even mildly bumpy streets sends shock waves into the cabin, resulting in a steady hum of shakes and vibrations. Your mother would probably notice and ask if something's wrong. Not up to par for the segment.

Noise & vibration

Road and tire noise is limited to a muted, dull hum on most road surfaces. Some wind noise leaks in at the front pillars, but it ts muted and acceptable. But the relative serenity is broken by a suspension that transmits too much road shake and shudder into the cabin — more mail truck than GMC.

Climate control

The control layout is simple other than the four buttons for vent mode, which is excessive. Central vertical vents distribute air poorly, but steering wheel heats up nicely. Seats offer cushion-only or cushion-and-seatback heating, a nice feature. Ventilated seats aren't available in any trim level.


The interior is attractive and well-configured, but some controls are awkwardly placed. Taller drivers will want the steering wheel to extend farther. The panoramic sunroof cuts into rear headroom for taller folks, but overall this is a roomy cabin with good space for shoulders, legs and elbows.

Ease of use

Control placement is a mixed bag — the headlight switch is by your knee, Snow mode in center console. Least impressive is the Terrain's unnecessarily clumsy transmission interface — pull switches placed below the climate controls. There's no way to avoid using those on every drive.

Getting in/getting out

The low seat bolsters make it easy to slide into front and rear seats. The doors open between 60 and 75 degrees, making for a wide opening. The step-in height is low enough for most passengers to get in and out with minimal effort.

Driving position

Plenty of seat adjustment up and down, as well as fore and aft seat travel. Wide range of adjustment should suit most drivers, although taller drivers might wish for more steering wheel extension so they won't need to sit too close or upright to the steering wheel.


There's good headroom up front, although the sloping roofline and panoramic sunroof lower the ceiling and may infringe on the headroom of taller drivers and passengers. Also good space between arms, elbows and door panels, which helps this small SUV feel larger


Truck-ish forward view — the deep, angled dash makes it hard to know where the front really is. The front side windows offer a good view, less so out the rear side windows. The rear-most side windows are more decorative than useful, and the rear window is too narrow.


The Terrain shares the same solid feeling as most GMC trucks and SUVs. There's a solidity to the sheet metal, upholstery and interior materials that imparts confidence and a sense of safety. Cabin materials aren't particularly special, but they look and feel high-quality.


The Terrain doesn't offer an abundance of cargo space compared to some rivals, but can handle most routine hauling and cargo needs. Some of its more thoughtful features — such as small trays and cubbies and especially a fold-flat front passenger seat — offer an edge.

Small-item storage

Plenty of bins, trays and pockets available to hold personal items. The cutout above the glovebox for a front passenger's mobile device is a nice touch, as are the trays in the rear door panels. Thoughtful touches designed with family and passengers of all ages in mind.

Cargo space

With rear seats folded, the Terrain's 63 cubic feet of cargo space lags behind benchmarks (Honda CR-V, Toyota RAV-4). But a fold-flat front passenger seat is a nice touch. The power liftgate and low liftover height make cargo loading easy, too.

Child safety seat accommodation

LATCH anchors are easy to find and connect to, and there's plenty of space for forward-facing seats. Rear-facing seats fit well as long as driver and front passenger can keep their seats reasonably forward. There's no top-tether for middle seat, but there's one in the rear seatback.


Our test car, with its 1.5-liter four-cylinder engine, is rated to tow up to 1,500 pounds, about the same as most other four-cylinder-powered SUVs in the class. Equipped with the optional 2.0-liter turbo-four, the Terrain can tow up to 3,500 pounds.


The Terrain deserves high marks for its tech, improving on the mediocre offerings of past models. Plenty of features are standard throughout the lineup, multiple driver aids are available, and six USB ports help ensure that all devices get charged. Navigation comes with strings attached, though.

Audio & navigation

The optional Bose sound system offers surprising power and clarity, but leave your discs at home; there's no CD player. Navigation is easy to use and looks sharp, but you'll also need to buy a power liftgate to get it.

Smartphone integration

Apple CarPlay and Android Auto come standard. Apple CarPlay beats GMC's native software for ease of use, but the standard system works fine for those outside the Apple/Android ecosystem. Six (!) USB ports for device charging; one is even the new USB-C standard.

Driver aids

Forward collision warning system has adjustable sensitivity (pick your preferred threshold of panic). Lane keeping assist is insistent, almost intrusive, to keep you within the lines. Might motivate more turn signal use. Safety alert seat remains an innovation that we prefer to beeps and flashes.

Voice control

The GMC native software and Apple CarPlay both decipher speech commands fairly well. CarPlay understands natural speech slightly better, but it relies on an internet connection. Native software requires staying within well-defined prompts and parameters.

I did a no trade deal and bought mine for $10,100 under MSRP and if I had been willing to take a black one I could have got it as low as $10,800 under MSRP it took a lot of negotiating but DO NOT OVERPAY keep firm and get your Terrain for $10,000 to $11,000 under MSRP. It is amazing how much profit some dealers expect to make on a single deal. Two dealers that touted themselves as "Zero Negotiation, No Haggle, No Hassle" was over $4,000 higher for what they termed their "Best Price" deal. BE EXTREMELY CAREFUL don't let some dealer put over $4,000 of your hard earned money in their pocket!!!!!!!! Dealers will try to bait you with "INVOICE PRICING" acting like they are losing money if they go any cheaper - doesn't mean a thing (they don't tell you about "HOLD BACK") and ask them to throw some "FLEX CASH" into the deal that is what it will take to get your best deal and don't be shy about holding firm and saying NO to their counter offers after about a dozen phone calls and counter offers the dealer I ultimately bought mine from came to my terms after originally starting off $2,294 higher and if I had really wanted to play hardball I think I could have gotten it a few hundred cheaper. GOOD LUCK in getting a new Terrain at a GOOD PRICE!!!!!!!!!
Never know when something may go wrong
We purchased our 2018 SLT diesel Terran in September on 2017. It was a very early build and we had just sold back our 2012 VW jetta diesel due to VW fraud. It started out good but after a couple of months, things started going south. First it was the radio would just go dead and nothing could be done to get it back on until it wanted to. Of course, this would never happen at the dealership so nothing has been done to fix it to date. Then about 3000 miles I got a warning that the DEF system was low. After filling DEF, I kept getting different DEF warnings and vehicle shut down warnings. It stooped this for 2 days and on my way to Yuma Az, the warnings all came back, the vehicle went into limp mode and we barely made the last 60 miles to dealership. They found the DEF wire harness was to close to drive shaft and it wore thru the harness and shorted out the system. Back on the road that day. Move forward to August of 2018 and problems again. My wife called and said it quit and I had to leave work to go get her. It started up when i got there and she drove it about 600 yards to truck stop. It was smoking heavily and had no power. I contacted Onstar roadside service and it was towed to nearest dealership. It was diagnosed as a injector failure and then plugged the DOC. We were told the DOC was on BOP and no date when it may show up. After 28 days we were finally notified the vehicle was repaired. They blamed my K&N filter for the issues and removed it. K&N says there is no way and is helping me with this matter. The radio still quits at times and my wife is almost scared to take it any further than work and grocery store. I thought GMC would put out a better product and not have these type of issues. I tried to make a deal trading it in at the dealership we purchased it from but I would have to take a 38% loss in less than a year. I seems they know they cant sell it again.I will go back to foreign vehicles again as I have had much better luck
Diesel engine (Iszusu) is crap
This diesel engine is crap. Beware. You might be traveling on the Interstate at 70mph when all of a sudden, with no reason or warning, this GMC will throttle you down to 45mph. So, get ready to use your hazards as you rush to the slow lane and hope your GMC Terrain TurboDiesel makes it to the next exit. Good thing this is a company car and I can get my company to NEVER DO BUSINESS WITH GM AGAIN. Do not buy this car as the diesel engine is crap and the Dealers have no idea how to deal with it or the weird messages, combined with the check engine light, that show up ion the dash, seemingly translated from Czech.
Terrain Rocks
I would buy it again in a heartbeat

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.

Compare GMC Terrain & Chevrolet Equinox features

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.
