2017 GMC Terrain

Crossover SUV shoppers just can't quit the strong-selling 2017 GMC Terrain. But the current-generation Terrain is now in its eighth year on the market, and every major rival has received an overhaul during that stretch. How does the Terrain stay in the game? The roomy backseat certainly helps, as does the powerful optional V6 engine. We'll also mention the quiet, comfortable ride as a relative strength in this class.

The Denali version of the 2017 Terrain receives special styling details. The model's overall look is getting pretty familiar, though.

But as you might imagine, time hasn't been kind to the Terrain in some other respects. The base four-cylinder engine provides both underwhelming acceleration and disappointing real-world fuel economy, while the dashboard is showing its age thanks to a hard-to-reach touchscreen and some ergonomic faux pas. Furthermore, smartphone users -- i.e., just about every car shopper these days -- should note that Bluetooth audio connectivity isn't even available on the two lowest trim levels (SL and SLE-1).

The 2017 Terrain remains a versatile and generally competent crossover, but we'd recommend taking a close look at a number of its rivals before making a final decision. Segment leaders include the enduringly well-rounded Honda CR-V, the significantly refreshed Toyota RAV4 and the sporty yet practical Mazda CX-5. We also like the redesigned Kia Sportage, which has a big backseat like the Terrain, along with contemporary cabin technology. Faced with distinguished competitors like these, the 2017 GMC Terrain has its work cut out if it wants to win your heart.

The 2017 GMC Terrain is fitted with standard antilock brakes, stability and traction control, front-seat side-impact airbags, side curtain airbags and a rearview camera. Also standard is GM's OnStar emergency communications system, which includes automatic crash notification, an emergency assistance button, remote door unlock and stolen vehicle assistance.

Lane-departure warning, forward-collision alert, rear parking sensors and a blind-spot monitor with rear cross-traffic alert are optional on the SLE-2 and SLT trim levels and standard on Denali.

In Edmunds testing, a Terrain Denali V6 AWD stopped from 60 mph in a satisfactory 122 feet.
In government crash tests, the Terrain earned an overall score of four stars out of five, with four stars for overall frontal-impact protection and five stars for side-impact protection. The Insurance Institute for Highway Safety gave the Terrain the best possible rating of "Good" in its small-overlap frontal-offset, moderate-overlap frontal-offset, side-impact and roof-strength tests. The seat/head restraint design was also rated "Good" for whiplash protection in rear impacts.

The 2017 GMC Terrain is available in five trim levels: SL, SLE-1, SLE-2, SLT and Denali.
Standard equipment for the base SL trim includes 18-inch alloy wheels, an auto-dimming rearview mirror, a rearview camera, cruise control, a power height-adjustable driver seat with power lumbar, a 60/40-split folding rear seat with sliding and reclining functions, a tilt-and-telescoping steering wheel, rear privacy glass, OnStar (with an onboard WiFi hotspot), Bluetooth phone (but not audio) connectivity, a 7-inch touchscreen interface and a six-speaker sound system with an auxiliary audio jack and a USB port.

Move up to the SLE-1 and you get heated mirrors and satellite radio. More importantly, all-wheel drive becomes available.

The SLE-2 builds upon the SLE-1, adding LED daytime running lights, automatic climate control, an eight-way power driver seat (with power lumbar), a leather-wrapped steering wheel, a Pioneer eight-speaker audio system and GM's IntelliLink system, which includes Bluetooth audio, voice controls and compatibility with Pandora and Stitcher smartphone apps. The available Convenience package adds heated front seats and remote engine start.

LED daytime running lights come standard on the SLE-2 trim level and above.

The SLT comes standard with the Convenience package and adds chrome exterior accents, ambient interior lighting and perforated leather upholstery.

Two Driver Alert package levels are available for the SLE-2 and SLT. The first level includes a blind-spot monitor, rear cross-traffic alert, rear parking sensors and (on the SLT only) an adjustable power liftgate. The second level adds forward-collision and lane-departure alerts. The SLT-only Memory package includes driver memory settings and an eight-way power passenger seat (with power lumbar).

Also optional on SLE-2 and SLT is the Nightfall package, which includes special 18-inch wheels and various gloss-black exterior accents.

The range-topping Denali has the SLT features as well as 19-inch wheels, an exclusive comfort-oriented suspension and Denali-specific exterior and interior trim. It also includes the Memory and Driver Alert I and II packages.

A navigation system is optional on Terrains in the SLE-2 trim and above.

The 2017 GMC Terrain comes standard with a 2.4-liter four-cylinder engine that produces 182 horsepower and 172 pound-feet of torque. Optional on SLE-2, SLT and Denali is a 3.6-liter V6 that churns out a hefty 301 hp and 272 lb-ft of torque. Both engines are paired with a six-speed automatic transmission. Front-wheel drive (FWD) is standard, and all-wheel drive (AWD) is optional on all trims except the base SL model.

In Edmunds testing, a mechanically comparable four-cylinder Chevrolet Equinox LT with FWD accelerated from zero to 60 mph in 9.5 seconds, which is notably slower than average for a small crossover. A Terrain Denali V6 AWD went from zero to 60 in a quick 7.1 seconds.

According to EPA fuel economy estimates, the four-cylinder engine should return 25 mpg combined (21 city/31 highway) with FWD, although we've been unable to match those numbers in our test vehicles. With AWD, the four-cylinder drops to 23 mpg combined (20/28). The V6 is rated at 20 mpg combined (17/24) with FWD and 18 mpg combined (16/23) with AWD.

With the four-cylinder engine, a properly equipped Terrain can tow 1,500 pounds; the V6 increases towing capacity to 3,500 pounds.
