2015 GMC Terrain: New Car Review

Editor’s note: If you’re looking for information on a newer GMC Terrain, we’ve published an updated review: 2019 GMC Terrain Review.


While some classify the GMC Terrain as a compact crossover, others say that it’s a midsize. The truth is that the 2015 GMC Terrain enjoys the best of both designations. It offers fuel economy fit for a compact and the roominess of a midsize utility. Add trucklike styling to the equation, and the GMC Terrain becomes a truly compelling package.

The Terrain delivers on many fronts, much like its mechanically identical counterpart, the well-rounded Chevrolet Equinox. Both crossovers are competent people-haulers emphasizing comfort, fuel economy, refinement and roominess — all things held in regard by those shopping for a family vehicle. The Terrain sets itself apart with distinctive styling elements such as a prominent grille, oversized wheel arches and squared-off body panels.

Despite its rugged name, the Terrain does not offer any kind of off-road capability. On the contrary, the only terrain that the Terrain is truly suited for is asphalt. The Terrain’s available all-wheel-drive system is fine for handling harsh weather and road conditions, but it’s less than ideal for treading a muddy trail through the woods.

How Much?


Fuel Economy

The Terrain offers two engine choices. A 2.4-liter 4-cylinder is standard; it’s hooked to a 6-speed automatic transmission and makes 182 horsepower and 172 lb-ft of torque. Fuel economy is 22 miles per gallon in the city and 32 mpg on the highway with front-wheel drive or 20 mpg city/29 mpg hwy with all-wheel drive (AWD).

Drivers who want more power can step up to the optional 3.6-liter V6, which makes 301 hp and 272 lb-ft of torque. The V6 is rated at 17 mpg city/24 mpg hwy with front-wheel drive or 16 mpg city/23 mpg hwy with AWD.

Standard Features & Options

The 2015 GMC Terrain is offered in five trim levels: base-level SLE-1 and SLE-2, midlevel SLT-1 and SLT-2, and a luxury-oriented model dubbed the Terrain Denali.

The base-level SLE-1 ($27,500) includes OnStar, Bluetooth, a 7-inch center-mounted touchscreen, a rearview camera, cruise control, 17-in alloy wheels, a power driver’s seat, and an auxiliary plug and USB port for music.

Step up to the SLE-2 ($29,000), and you add automatic climate control, GM’s IntelliLink infotainment system with voice commands, a Pioneer audio system, a power passenger seat and roof rails.

Next up is the SLT-1 ($30,500), which boasts heated front seats, leather upholstery and a remote engine starter.

From there, drivers can move to the SLT-2 ($33,800), which adds a sunroof, 18-in wheels, rear park assist, a lane-departure warning system, a forward-collision warning system, a power lift gate, driver’s seat memory and other accents.

Finally, topping the Terrain lineup is the Denali ($36,200), which offers rear cross-traffic alert, a blind spot monitoring system, unique wheels, and Denali-specific exterior and interior trim.

Many Terrain models offer optional features that are standard on higher trim levels. The SLE-2, for instance, offers a convenience package that’s standard on the SLT-1 and a safety package that’s standard on the SLT-2. Other options include a navigation system, all-wheel drive, a rear-seat DVD entertainment system and the 3.6-liter V6.


Standard safety comes from six airbags, OnStar emergency telematics, anti-lock brakes, stability control and traction control. To elevate occupant protection, GMC also offers optional lane-departure and forward-collision alert systems, part of the Safety package available on the SLE-2 and SLT-1 and standard on the SLT-2 and Denali. The Denali also includes a standard blind spot monitoring system and rear cross-traffic alert.

The Terrain received four overall stars in National Highway Traffic Safety Administration (NHTSA) crash-testing. It earned five stars in NHTSA’s side-impact test but received four stars in frontal and rollover assessments.

Behind the Wheel

First and foremost, the Terrain delivers a comfortable and quiet ride that’s well suited for daily commuting or long-distance road trips. GMC has gone to extra effort to make the Terrain’s cabin as free from exterior noise as possible. A plush, well-shielded driving experience is what the majority of family-centric buyers want, and the Terrain delivers.

The Terrain really isn’t fun to drive, though. Its handling is lackluster, and its steering feels numb and disconnected. Furthermore, the Terrain exhibits noticeable body roll in corners.

As for power, the 4-cylinder Terrain is a fine choice for everyday driving. Power delivery is smooth and steady throughout the rev band; the only time it may come up short is when the Terrain is loaded down with passengers and cargo.

Equipped with the 3.6-liter V6, the Terrain is noticeably more powerful. Off-the-line acceleration feels strong, and the V6 Terrain pulls highway-passing maneuvers without struggling, but compared with the base 4-cylinder, this engine takes a beating on fuel economy.

Although the Terrain is not ideal for going off pavement, it is a capable towing vehicle. Choosing the V6 and the optional trailer package lets the Terrain driver tow a small boat.

Other Cars to Consider

Honda CR-V — The CR-V offers more cargo capacity than the Terrain but no V6 engine option. Both vehicles provide comfortable transportation for five.

Toyota RAV4 — The latest RAV4 doesn’t have the Terrain’s bold styling or V6 power, but it’s high on value, fuel economy and interior room, even if it isn’t the most refined compact SUV around.

Ford Escape — The recently redesigned Escape has more high-tech features than the Terrain, and it offers a wider range of engine choices, but the Terrain’s sliding rear seat gives it more interior versatility.

Kia Sportage — The Sportage is sportier and more fun to drive than the Terrain, but the Terrain offers more cargo room and a roomier second-row seat, which slides and reclines.

Autotrader’s Advice

The 2015 GMC Terrain variant that makes the most sense is the SLT-1 trim matched with the 4-cylinder engine. The 4-cylinder provides adequate power and better fuel economy than the V6, and the SLT-1 trim offers the best value among the five models. It comes equipped with features such as remote starting, heated front seats, leather upholstery, a touchscreen audio system and a backup camera — all included without causing you to break the bank. We also suggest opting for the available navigation system and Safety package, and for those living in colder regions, all-wheel drive is highly recommended. Otherwise, stick to the thriftier front-wheel-drive setup. Find a GMC Terrain for sale

  1. When you reviewers write these you really ought to compare apples to apples. The review says other cars to consider, Rav4, CRV & KIA all have almost no rear leg room. Not sure about the Ford.
