Loading Comparison...


The 2018 GMC Terrain compact crossover is all new, from the downsized chassis, to the all-turbo/9-speed powertrain, to the new body that moves from macho to mundane. The Terrain is much like the Chevy Equinox, with the same footprint, but sheetmetal that’s sculpted into bold scoops and creases, and bigger fenders.

The compact crossover is a tough class. Terrain competes not only against its near-twin Equinox, but also Honda CR-V, Toyota RAV4, Ford Escape, Mazda CX-5, and others. Terrain’s acceleration is smart, its handling sound, and its ride well tuned.

For 2018, the excellent 3.6-liter GM V6 engine gets disappeared. Its 301 horsepower will be missed in a vehicle as heavy as the Terrain, at 3500 pounds. Its replacement is a turbocharged 2.0-liter I4 making 252 horsepower, with vivid acceleration but a big thirst, achieving 24 mpg EPA Combined with fwd, 23 mpg with awd.

The base engine gets retired too. The old one was a 2.4-liter I4 with direct injection, making 180 horsepower and getting 25 mpg. The new one is a turbocharged 1.5-liter making 170 horsepower, but with more torque and fuel mileage of 28 mpg with fwd, 26 mpg with awd.

If the stats of the new engines don’t sound so impressive, look at it this way: the new 252-horsepower I4 gets just 1 less mpg than the old 180-horsepower one.

There’s also a diesel engine that gets better fuel mileage, 32 mpg with either front- or all-wheel drive. It’s entertaining in a grown-up way, but less energetic.

The new 9-speed automatic transmission pairs beautifully with the new engines, but lacks manual control, with audio controls where we wish there were paddle shifters.


GMC Terrain comes as SL, SLE, SLT, and Denali. Front-wheel drive is standard, all-wheel drive available ($1750) on every model but the SL. The turbocharged 2.0-liter is an option on the Terrain SLE and SLT, and standard on the Denali.

Terrain SL ($25,990) is equipped with premium cloth, power features, active noise cancellation, air conditioning, cruise control, keyless ignition, 17-inch wheels, 3.5-inch digital display between the gauges, and rearview camera. There is a 7.0-inch touchscreen for audio, OnStar and in-car data hardware, two USB ports, and auxiliary jack, Bluetooth with audio streaming, and Apple CarPlay and Android Auto. (Prices are MSRP and do not include destination charge.)

Terrain SLE ($28,815) adds dual-zone automatic climate control. A trailer-tow package is an option on the SLE with the 2.0-liter turbo engine.

Terrain SLT ($32,315) gets leather seats and an 8.0-inch touchscreen, satellite radio, blind-spot monitors, a 110-volt power outlet, remote start, power driver seat, heated front seats, panoramic sunroof.

Denali ($38,515) adds a handsfree tailgate, a power passenger front seat, HD radio, seven-speaker audio, navigation, 19-inch wheels, LED headlamps, and a bundle of safety equipment including forward-collision warnings with automatic emergency braking, blind-spot monitors, lane-departure warnings, and rear parking sensors. The forward-collision warning bundle remains an option, as are surround-view cameras and automatic park assist. So are wireless smartphone charging, ventilated front seats, and heated rear seats.

The turbodiesel is available in SLE and SLT trim.


The styling of the previous Terrain was almost Hummer-like, with its edges and flat panels. The all-new Terrain smoothes most of them away, to a place where character gets blurred. It’s neither attractive nor distinctive, on the road it’s just another crossover.

The large grille is either a fat oval with chopped edges, or a big rectangle with chopped corners. It looks way better in black, like on the base SL, than with chrome, like the Denali. In fact it looks horrendous in the way GM does the chrome. The SL also has matte black plastic running the bottom perimeter of the car, front and rear fascia plus over the wheels and under the doors. It gives the Terrain some rugged purpose, and looks better than the Denali’s barely-flared metal fenders, although the Denali’s 19-inch painted alloy wheels smartly fill the wheelwells. The SL is cleaner, absent the Denali’s strip of chrome trim along the doors and over the window line.

The headlamps are shaped like the simplest bare-hand puppet, forefinger curved over the thumb, each facing center. They don’t grab you. Except if you imagine them yakking at each other over the top of the grille.

The rear end is shaped like midsize GMC Acadia but better looking.

Just for effect, that doesn’t work, the rear window is pinched, asymmetrically, and blacked out in back, continuing onto a wide band of black across the rear pillar. It’s supposed to flow, which it does about as much as painting a wide stripe on a box.


The all-new Terrain loses some inches in the wheelbase, length, and width, but still has about the same seating space as the Ford Escape and Toyota Rav4. Base vehicles have cloth seats with manual adjustment, while the leather has more bolstering, ventilation, and power adjustment. They’re good for long hours in the saddle, as long as you’re not too tall, as the driver’s seat lacks the enough support under the legs. The seating position is lower than before, which makes the Terrain feel less SUV-like.

The cabin isn’t cohesive, it looks like three separate zones, although it can come together with leather in a warm color, and aluminum trim. Compared to the Equinox, the materials are softer and it’s quieter, with more sound insulation under the floor. But the door panels have big chunks of the same plastic that composes most of the buttons on the instrument panel. This shouldn’t happen on an SUV in this price range.

The standard infotainment system is lovely and simple, with a 7.0-inch screen and big icons. The display is clear, bright, responsive, fast, and doesn’t drop its smartphone connection. But mostly it’s clean, without too many features or too much information.

There is ample small storage in the cabin, with a deep console double door pockets. There’s a special slot for a cellphone for the front passenger. In the rear cargo area, there are bins under the floor.

The downsizing is felt more in the rear than the front; legroom has decreased a tiny amount, from 39.9 inches to 39.7, but it feels like more since the second-row seat doesn’t slide any more. The available panoramic sunroof cuts 1.6 inches from headroom, in front as well. The rear passengers will appreciate tall doors, so there’s less ducking to climb in, but the they won’t appreciate the flat seat bottoms, even in leather.

The seats fold but not quite flat, to provide 63.3 cubic feet of cargo space, way less than the Honda CR-V. Behind the rear seats there is 29.6 cubic feet, again less than the Honda. The good news is the front passenger seat folds flat, like the Honda Fit, to provide room for long things from 2x4s to kayaks. An optional liftgate opens at the wave of a foot, to make loading those things easier.

Driving Impressions

The base engine, a turbocharged 1.5-liter I4, feels refined and quiet. It makes 170 horsepower and a strong 203 pound-feet of torque that comes at low revs, reaching its max at 2000 rpm. That gives it gutsy acceleration and the ability to push the 3500-pound Terrain around with some authority. The 9-speed automatic helps in this challenge, while the Equinox struggles with a 6-speed.

The transmission itself is smoother than other 9-speeds (Chrysler and Mercedes come to mind), but the method of shifting gears with a switch on the console, which is almost out of reach, is a what-were-they-thinking moment–more than a moment, it’s a lifetime with the car. And the notion of audio controls in the place of paddleshifters is one of the worst GM ideas since the Aztek.

The transmission pairs brilliantly with the new 252-hp 2.0-liter turbo that felt strong during our quick runs in the Appalachians, like it were capable of zero to sixty miles per hour in about 7.5 seconds. With 260 pound-feet of torque, it pumps out steady power and a cool whistling turbo sound as it climbs through the gears. If only it had a usual manual control, namely paddle shifters, we’d be comparing it to the 2.0-liter EcoBoost engine of the Ford Escape, the benchmark for thrust and eagerness. Manual shifting would also be useful for towing, a likely prospect since this engine is rated to tow 3500 pounds.

Ironically, surprisingly, the new 1.6-liter turbodiesel can only tow 1500 pounds, same as the base 1.5-liter. Diesel torque aside, it only makes 137 horsepower. It’s heavier, slower, and vibrates a lot. It’s more expensive and only comes with a 6-speed transmission. It’s not worth the extra 9 mpg, at least not to us.

The optional all-wheel-drive is a part time, activated by a knob on the console, with different traction modes. It’s mechanically simpler, without a brain to self-activate.

The Terrain’s ride is biased more toward comfort than cornering. The ride only reveals its compact crossover nature with the sharpest of bumps. The suspension is same as before, struts in front and four links in rear, but the old hydraulic rack-and-pinion steering is replaced by electric power assist.

With the standard 17-inch wheels and tires, the handling is poised and predictable, if not very enthusiastic. But it helped us avoid six deer and two washed-out roads, during our seat time. The Denali has a higher state of suspension tune and 19-wheel wheels with better all-season tires. It tracks true but still doesn’t offer much feedback.


GMC Terrain is all new for 2018, a compact crossover SUV.

About These Prices

As you know, pricing cars is particularly complicated. One of our duties at CarQuotes.com is to help our customers comprehend this process better.

Three important prices we may show on a particular vehicle

CarQuotes.com Estimated Target Price is for research purposes only. It reflects a typical, negotiated price (before taxes and other customary fees and charges, such as dealer documentation fees, tire and battery disposal fees, license and registration, and where applicable, finance charges) generally found for the vehicle that you selected. The Estimated Target Price is NOT a price quote from CarQuotes.com or any other dealer. If you request a price quote from a dealer via CarQuotes.com displaying an estimated target price, your price may differ.

Invoice is commonly known as the published amount that the dealer paid the manufacturer for the vehicle. This may or may not represent a close relation to the dealer’s actual cost, but can be beneficial as a benchmark. This figure is available on many other web sites however CarQuotes.com adds an estimate of local and regional fees from manufacturer to the dealers to this price, which makes it very close to the actual invoice amount for cars at your local dealer.

MSRP is the Manufacturer’s Suggested Retail Price. This is a proposed price only. For most vehicles, the CarQuotes.com price is below this amount. Some high demand cars may be priced over this amount.

Estimated Target Price

The CarQuotes.com Target Price is to be used as a general guide that reflects a typical, market price (before taxes and other customary fees and charges) generally found for the vehicle that you selected. This price is based on our research and estimates of supply and demand in the marketplace. There are many factors that go into the final price of a particular vehicle including local supply and demand. Your final price may differ.

CarQuotes.com Estimated Target Prices include

The ’base’ price of the vehicle
All options that you select
Base Destination Charges — this is a charge that is added to the base price for every vehicle
Any related Estimated Manufacture to Consumer Cash Rebates. Note: rebates are subject to change at any time. Please make sure to confirm any consumer Cash rebates with your dealer representative at the time of purchase.

CarQuotes.com Estimated price(s) do NOT include any of the following:

Local taxes, license fees and other local fees, such as dealer documentation fees, tire and battery disposal fees, and where applicable, finance charges — these fees are also excluded from Dealer Invoice and MSRP and would be excluded from most advertisements you might see.
Random ’special qualification’ rebates — i.e., for new college grads only; for customers trading in a specific type of car.  Ask your dealer Representative for more information on ’special qualification’ rebates.

CarQuotes Estimated Dealer Price

The Estimated CarQuotes Dealer Price is an estimate of the pricing presented to CarQuotes members from CarQuotes Authorized Dealers in your area, and is calculated by subtracting an estimated savings value from the Manufacturer’s Suggested Retail Price ("MSRP") as well as a value that relates to invoice for the "ideal vehicle" you configured. Dealer documentation, administrative or similar processing fees are not included in the price estimate. Any vehicle configured on the CarQuotes website is an "ideal vehicle" and may not exist at a CarQuotes Authorized Dealer or any other partner dealer. Each Dealer attempts to match a member’s vehicle preferences with the best possible selection from current, in-stock inventory.

Estimated Savings

The Estimated Savings represents the estimated amount of savings off of MSRP available to you from CarQuotes Dealers for a vehicle consistent with your configured preferences plus any customer incentives currently available.  This is also true when it comes to CarQuotes estimated target prices. Your actual savings will depend on several factors including market conditions, the style of vehicle you select, installed options, dealer coverage, and applicable manufacturer incentives. Each dealer sets its own pricing.

Advertised Rebates, Special Manufacturer Financing or Leasing Programs

In most cases, you must choose between these programs OR a customer rebate or a special manufacturer-to-dealer incentive that may or may not already be included in your CarQuotes.com Target Price. So, your final price may go up if you take advantage of special manufacturer financing. Credit Union members should contact their Credit Union loan department to determine what type of loan and financing options are right for you.

Please note that CarQuotes.com strives to include identified manufacturer incentives within the CarQuotes.com Target Price. CarQuotes.com does not administer these programs, which are subject to and often change without notice. Eligibility for these programs is subject to verification by a licensed auto dealer.

Ask your dealer representative for complete manufacturer program details for your area, and how participation in these programs will affect your price.

Base Vehicle

The base vehicle is the vehicle before any optional equipment or destination fees have been added. All of the standard features are included in the base vehicle.


This is the total charge for all optional equipment included in the configuration of your virtual vehicle. The Options charge varies depending on whether it is calculated based on the Factory Invoice or MSRP. Options are not included in the base vehicle price and are not considered standard features.

Regional Fees

A Regional Fee is the fee a manufacturer charges a dealer to advertise and promote the vehicle in the dealer’s market. CarQuotes also includes estimated manufacturer preparation charges (manufacturer charges to the dealer to cover any work done on the car prior to delivering it to the dealership) and fuel charges (the charge for the fuel in the tank when the buyer purchases the vehicle) in this total. CarQuotes attempts to include regional ad fees in its Factory Invoice calculations; other sites at times do not.

Destination Fees

These are the amounts that manufacturers charge to deliver a vehicle from the factory to the dealership.

Customer Incentives

Customer incentives are also commonly known as customer cash or bonus incentives. These incentives are offered by manufacturers as a way of enticing buyers into purchasing a vehicle.


Note: Dealer Invoice amount might not be the amount that the dealer paid to the manufacturer

Dealer Invoice price may or may not bear close relation to a dealer’s actual cost for the vehicle. In some cases, a cost for a vehicle may be significantly less than the invoice price originally paid for the vehicle. Any difference between invoice price and the dealer’s final cost may be caused by many factors including factory refunds, rebates, allowances, or incentives which the manufacturer or distributor may provide to the dealer.
