It’s not hard to see the importance of the Terrain compact crossover to the GMC brand. It’s the division’s second best-selling model, accounting for one in six GMC sales last year. Yet eight years after it was first introduced, the crossover is ready for an update. The all-new 2018 GMC Terrain bowing at the Detroit Auto Show arrives with a new design, a revamped interior, and a trio of turbocharged engines.

As we first saw in a teaser photo, the 2018 GMC Terrain takes a pretty big styling risk compared to its predecessor. With a sleek, swept-back design all round, highlighted by a floating pillar treatment below a sloping roofline, it’s a striking look. We’re also happy to see a bit more visual differentiation from the GMC’s platform-mate, the Chevy Equinox, than in prior years.

The new Terrain is 3.2 inches shorter in length on a 5.2-inch shorter wheelbase than before, and cargo room suffers as a result. With the rear seats raised, there’s now 29.6 cubic feet of storage, down by 2.0 from the 2017 model; with the back seats lowered, storage space increases to 63.3 cubic feet, which is only 0.4 cubic feet less than the outgoing model.

Like the Equinox, the new Terrain will use three turbocharged engines – say goodbye to the naturally aspirated inline-four and V6 of the prior model. There will be 1.5- and 2.0-liter turbocharged gas engines with a nine-speed automatic transmission, as well as a 1.6-liter turbodiesel with a six-speed automatic. The gas engines make 170 horsepower (127 kilowatts) and 252 hp (188 kw). The diesel Terrain will offer only 137 hp (102 kw) but cranks out an impressive 240 pound-feet (325 Newton-meters) of torque.

Just like its Chevy sibling, the Terrain has gone on a big diet for its new generation. GMC says the lightest model, a front-wheel-drive Terrain with the 1.5-liter gas engine, weighs 3,327 pounds, or 465 lb less than the skinniest 2017 model. That, along with the new engines and transmissions, should pay dividends in fuel efficiency.

As is de rigeur in the crossover class, both front- and all-wheel-drive models will be available. The GMC Terrain will have selectable drive modes, including one that switches the AWD system to disconnect the rear prop shaft to save fuel.

Interior features include a new electronic shift lever that takes up less space in the center console, a fold-flat passenger seat, and rear seats that now fold flat to the floor. The crossover also has active noise cancellation as standard, plus available aluminum and leather trim. Tech options include 7- or 8-inch touchscreen infotainment systems, an available Bose sound system, and an upgraded active-safety suite with a 360-degree camera system, forward-collision warning, automatic pre-collision braking, lane-keep assist, and the Rear Seat Reminder feature found on many General Motors vehicles.

In typical GMC fashion, trim levels start at SL, continuing through SLE, SLT, and the ultra-lux Denali. The lower two trims come with 17-inch wheels, the SLT wears 18s, and the Denali has 19. Other Denali-specific features include LED headlights, more exterior chrome than a disco ball, a heated steering wheel, a power liftgate, and navigation.

GMC today introduced the all-new 2018 Terrain and unveiled the next chapter of GMC design via a boldly styled and intelligently engineered successor to the brand’s popular compact SUV. The Terrain offers greater refinement and versatility to adapt to customers’ unique needs, and it’s packed with more available advanced safety technologies than ever before. GMC offers customers the widest range of choices yet, with three all-new available turbocharged propulsion systems, including a new turbo-diesel. Two new efficiency-enhancing nine-speed automatic transmissions are matched with the gas engines — a first application for the GMC lineup. Continuing the momentum of owning 25 percent of GMC’s overall retail sales, Denali returns to the Terrain with greater exclusivity than ever, offeringa distinctive range-topping design and uniquely refined features. “ GMC’s strong growth over the past decade is due in large part to Terrain,”  said Duncan Aldred, vice president of global GMC Sales and Marketing. “ The all-new Terrain builds on that success, leveraging GMC’s proven premium SUV experience to shake up the largest vehicle segment, with a strong blend of design, functionality and engineering excellence.” The 2018 Terrain goes on sale this summer in SL, SLE, SLT and Denali models, maintaining the momentum created by the first-generation model, of which more than 700,000 have been sold in North America since it went on sale in 2009.Bold, modern design  The new Terrain’s bold exterior signals the next chapter of GMC’s design language, evolving the brand’s signature cues with stronger, sharper and more sculpted elements such as the grille and lighting features. Its shape was refined in the wind tunnel to help ensure the distinctive profile cuts through the air with optimal efficiency and quietness.  “ It is a striking design with functional beauty,”  said Helen Emsley, executive director, Global GMC Design. “ There’s confidence and optimism in its stance, with exceptional attention to detail that speaks to GMC’s rise as a premium brand.” Elevating GMC’s new design, the all-new Terrain Denali will feature its signature satin chrome grille along with Denali-specific accents including body-color fascias and lower trim, plus chrome roof rails, door handles, side mirror caps and body-side molding. Additionally, LED headlamps and 19-inch ultra-bright machined aluminum wheels are standard on Denali. 

All other models feature signature LED daytime running lamps and tail lamps. Bi-functional HID headlamps are standard on SL, SLE and SLT. Additionally, 17-inch wheels are standard on SL and SLE, with 18-inch wheels available on SLE and standard on SLT. Turbocharged propulsion choices A range of three all-new turbocharged engines, including an all-new 1.6L turbo-diesel, provides more choices when it comes to performance, efficiency and capability in the all-new 2018 GMC Terrain. New 1.5L and 2.0L turbocharged gas engines are matched with two unique new nine-speed automatic transmissions, with the 2.0L turbo engine offering stronger acceleration and a higher degree of performance than its 1.5L counterpart. GMC’s new Electronic Precision Shift enables more storage room in the center console by replacing the conventional transmission shifter with electronically controlled gear selection consisting of intuitive push buttons and pull triggers.  The Terrain comes standard with GMC’s driver-controllable Traction Select system, which has choices for different driving conditions. Elements such as the throttle responses are optimized for the selected driving mode. AWD models include a FWD mode that disconnects the AWD system to minimize drag and optimize fuel economy, while the AWD mode offers all the benefits of an active AWD system. Refined, versatile and purposeful interior Like the exterior, the new Terrain’s interior makes a statement and serves as a fundamental component of the vehicle’s heightened emphasis on refinement and functionality. Elements such as authentic aluminum trim, soft-touch materials on the instrument panel and doors and standard active noise cancellation are premium features seamlessly integrated into the interior design for a luxurious customer experience. The Terrain Denali heightens the GMC experience throughout the new interior with a unique trim tint color and Denali-specific logos and piping on the front seats. Denali customers will benefit from additional standard features including a heated steering wheel, navigation, Bose premium 7-speaker sound system and a hands-free programmable power liftgate.  An expanded center console with pass-through storage underneath and side-by-side cupholders adds to the Terrain’s functionality. A new fold-flat front passenger seat and flat-folding rear seat help Terrain offer greater versatility for stowing longer items and make it easier to load cargo. There are also new under-floor compartments in the cargo area for more secure storage.  GMC keeps passengers connected with 7- and available 8-inch-diagonal infotainment systems, featuring compatibility with Apple CarPlay and Android Auto functionality and a standard OnStar 4G LTE Wi-Fi hotspot (data plan purchase required after limited trial period) that can accommodate up to seven mobile devices. Owners can also manage their vehicles remotely with the industry-leading myGMC mobile app via their compatible smartphones. Apple CarPlay and Android Auto compatibility are subject to their terms, privacy statements and data plan rates, and require a compatible smartphone.

Every new Terrain comes standard with five years of the OnStar Basic Plan1 at no additional cost. Among other benefits, this connectivity plan features OnStar Smart Driver, an opt-in service designed to help GMC owners maximize their vehicle’s overall performance, reduce wear and tear, monitor fuel efficiency and become better drivers —all factors that add to the overall ownership experience. Expanded range of safety features An expanded range of available active safety technologies is designed to enhance driver awareness and even help make it easier to park and maneuver in low-speed situations. The features include radar- and camera-based adaptive technologies that can provide alerts to potential crash threats, allowing the driver to react and make changes to potentially avoid them, including:

New Surround Vision

New Forward Collision Alert with Following Distance Indicator

New Low-Speed Forward Automatic Braking

New Lane Keep Assist with Lane Departure Warning

Lane Change Alert with Side Blind Zone Alert

Rear Cross Traffic Alert

New Safety Alert Seat  The new Terrain also features GMC’s new Rear Seat Reminder2 and Teen Driver3. Rear Seat Reminder alerts drivers to check the back seat as they exit their vehicles under certain circumstances, while Teen Driver allows parents to set controls and review an in-vehicle report card in order to help encourage better driving habits, even when adults are not in the vehicle.
