Depending on what kind of person you are, cosplay is either an incredibly fun and expressive way to interact with friends, or it's nothing more than a childish game of dress-up and making a fool of yourself. The same goes for cars, or, rather, SUVs (crossovers?), where buyers either appreciate when a certain car exaggerates its personality and its capabilities for visual appeal, or downright reject it as being disingenuous. These days, however, it seems more and more automakers are leaning into the cosplay effect—especially in the compact SUV segment, where "adventure-ready" packages are bringing new appeal to an otherwise dull and overdone category of automobile. The 2026 GMC Terrain AT4 is one of GM's latest efforts to gain market share here—a twin of the Chevrolet Equinox Activ—and after spending a week driving one, I'm convinced this might be the brand's best effort yet to battle more established Japanese rivals.I spent my time with the Terrain AT4 mostly where vehicles like this actually live: on city roads around Vancouver, in traffic, on poorly maintained pavement, along the Sea-to-Sky Highway, and hauling family, friends, and gear to various destinations. But I also visited Squamish Valley and let it get properly dirty on muddy, rutted, pothole-marked trails. The version I drove used GMC's EcoTec 1.5-litre turbo-four, paired with an eight-speed automatic, all-wheel drive, and wore General Grabber all-terrain rubber. On paper, that combination does not sound particularly menacing. The engine makes 175 horsepower and, in AWD form, 203 lb-ft of torque. The AT4 gets lifted ride height, AT4-exclusive Terrain mode, an off-road-tuned suspension, a front skid plate with a steel underbody shield, and a factory tow package rated at up to 1,500 pounds. EPA fuel economy for the AWD Terrain AT4 is 24 mpg city, 26 highway, and 25 combined. The AT4 starts at $39,400 in the U.S. for 2026.The Terrain AT4's appeal is not that it outmuscles the segment—it certainly does not. It is that it feels better sorted than you might expect. After driving a healthy number of its adventure-coded rivals—vehicles like the Subaru Forester Wilderness, Honda CR-V TrailSport, Toyota RAV4 Woodland, and Nissan Rogue Rock Creek—the GMC emerges as a slightly underrated answer to a question more people are starting to ask: what if you want the image and some of the utility of a soft-roader, but still want your daily driver to feel quiet, comfortable, spacious, and well screwed together? Powertrain & Driving Dynamics: 8.0/10The Terrain AT4's powertrain is a good reminder that numbers only tell part of the story. With 175 horsepower, it offers lower output than several rivals, but it makes up for it with 203 lb-ft of torque. The 2026 Subaru Forester Wilderness, for instance, makes 180 horsepower and 178 lb-ft, while the 2026.5 Nissan Rogue Rock Creek jumps to 201 horsepower and 225 lb-ft. The Honda CR-V TrailSport Hybrid and Toyota RAV4 Woodland also lean on electrification to feel punchier and more efficient in everyday use, both offering north of 200 horsepower.But what the GMC has going for it here is a conventional eight-speed automatic. In a segment increasingly full of CVTs, that makes a big difference. The Terrain never felt especially quick, and on long highway stretches, it could still feel a touch breathless, especially out on the Sea-to-Sky, where the road invites more confidence than the powertrain can always deliver. But from a stop, throttle response was better than expected, and around town, it felt more alert and more natural than some rivals that technically offer more on paper. In particular, it never felt as dreary or rubber-bandy as the Forester Wilderness can when you ask too much of its CVT-backed flat-four.That is not to say the GMC is perfect. At low speeds, the transmission can occasionally deliver the odd jerky shift, and under heavier load, the little turbo-four sounds exactly like what it is: a hardworking small-displacement engine trying to motivate a reasonably substantial compact SUV. But it settles down once underway, and most of the time the Terrain's powertrain disappears into the background in a way that suits the vehicle's mission. It is also worth noting that opting for AWD on the GMC Terrain (standard on AT4) gives you the 8-speed (which replaces a CVT) and some extra torque. Next year, the CVT will be eliminated altogether, and even FWD-equipped models will receive the 8-speed. Exterior Design: 8.5/10This is, without question, the best-looking GMC Terrain yet. Previous generations always struck me as slightly awkward. They were not ugly, exactly, but they lacked a certain sense of confidence. The proportions felt strange, and the detailing always looked a bit cheap. The overall shape always came across as trying harder to be "masculine" than its lacklustre underpinnings could convincingly support. This generation, introduced for 2025 and carried into 2026, fixes that. It looks more upright, more substantial, and much more coherent than either of its previous generations did. The visual mass has been pushed rearward, the window line is no longer doing anything strange for its own sake, and the whole vehicle now projects the kind of square-shouldered toughness buyers in this segment clearly want, and that its genuine capability can back up. The AT4 trim helps further. GMC gives it a darkened grille, black mirror caps and roof rails, 17-inch dark machined wheels, all-terrain tires, a lifted stance, red recovery hooks, LED fog lamps, and underbody protection. I especially enjoyed the visual appeal of its lighted amber side markers. These are not merely decorative changes, even if some of them obviously also serve the usual lifestyle-branding function. The good news is that the Terrain wears them well. It does not look like a mall crawler in hiking boots, even if that's realistically what most of them will end up being used as. It looks properly resolved. In white, especially against the muddy browns and deep greens of British Columbia's backroads, it looked great. Tough without being cartoonish or distasteful. Modern without all the cheesy cop-outs like split headlights and full-width LED light bars. There is a clean, honest visual identity to it, inside and out, that I came to appreciate even more over time.Need New Tires?

The cabin doesn't necessarily feel luxurious, but it does feel thoughtfully assembled and relatively upscale for the class. The materials are not lavish, but they are chosen appropriately and, more importantly, feel properly put together. That is not always true in this corner of the market, where some rivals hide mediocre execution behind trendy textures and giant screens. My tester wore black CoreTec upholstery, and the overall atmosphere was comfortable and sensible rather than flashy. The front seats were easy to dial in thanks to power adjustments, and the mix of heated and ventilated front seats made particular sense in an early Vancouver spring, where you can leave the house needing one and come back wanting the other. The optional heated rear outboard seats and a heated steering wheel only added to the experience. Space is another strength. Official GMC specs list 29.8 cubic feet of cargo room behind the second row and 63.5 cubic feet with the rear seats folded, along with 40.5 inches of front headroom and 43.9 inches of front legroom. For comparison, Toyota quotes up to 37.8 cubic feet of cargo space for the 2026 RAV4, so the RAV4 still wins the outright number behind the second row. But the Terrain is still quite competitive here compared to many of its rivals, and offers slightly better occupant dimensions, generally speaking. There are also welcome practical touches throughout. The split-folding rear seats, underfloor storage area, and console pass-through all make the Terrain more usable for adventurous outings. The only notable annoyance in my tester was the stereo, and even then, it was mostly pretty solid. It sounded decent enough, but the bass occasionally rattled the door panels, which is exactly the kind of petty irritation that stands out more in a cabin this otherwise solid. It is the automotive equivalent of finding out that your hot date chews with their mouth open. Still, overall, the Terrain supports a feeling I have had for a while now: Ford and Stellantis still know how to build characterful things, but modern GM products often feel more carefully assembled. That impression lines up, at least directionally, with recent J.D. Power data. In the 2025 U.S. Vehicle Dependability Study, all four GM brands finished among the top 10, with Buick topping the mass-market segment. J.D. Power's 2025 Initial Quality Study also found the industry average improved slightly year over year. Those studies are not scripture, and they are certainly not the final word on long-term quality, but they do support the idea that GM's current emphasis on fit, finish, and execution is not imaginary. Technology: 8.2/10Modern General Motors interiors have become much better at making technology feel integrated rather than bolted on by committee, and the Terrain AT4 is another solid example of that. Every 2026 Terrain gets a 15-inch infotainment touchscreen and an 11-inch digital driver display, while the AT4 also offers up to 8 available camera views, wireless smartphone charging, Google built-in compatibility, and a robust roster of driver-assistance features. In daily use, the system was easy to get along with. It loaded quickly every time I started the car, which sounds like a basic thing until you spend enough time in new vehicles that still behave like they are waking from a hangover each morning. I used wireless Apple CarPlay for most of my drive time, and it behaved properly and consistently. The part I liked most, oddly enough, was also one of the least consequential: the topographical map theme displayed on the screens before ignition. It is a small design flourish, but it works well towards establishing the Terrain AT4's sense of identity. Too many crossovers today are technically competent but spiritually anonymous, and this niche subsegment of "adventure-ready soft-roaders" generally does a good job at remedying this sense of dullness. The crisp gauge cluster and responsive camera system also left a strong impression. In a vehicle like this, where narrow trails, muddy pull-offs, and urban parking lots are all part of the territory, camera quality is a valid concern. Grainy, low-resolution feeds that look like security cam footage from a liquor store in 2007 simply don't cut it anymore. The Terrain's setup avoided this plague and felt appropriately modern throughout. Pricing & Value: 7.2/10In the U.S., the 2026 Terrain AT4 starts at $39,400. That puts it in the thick of this increasingly fashionable soft-roader fight. The 2026 Toyota RAV4 Woodland starts at $39,900, the 2026 Honda CR-V TrailSport Hybrid starts at $38,800, and the 2026.5 Nissan Rogue Rock Creek AWD starts at $33,990. The Subaru Forester Wilderness, which acts as a sort of North Star in this segment, starts at $38,385 with its big selling point being the far more serious 9.3 inches of ground clearance. That pricing makes the GMC neither a screaming bargain nor an obvious rip-off, but it gets even more expensive when you add the Convenience and Tech packages, as well as options like a panoramic moonroof. With delivery and destination fees included, it's easy for the Terrain AT4's price tag to exceed $45,000 once a few extra boxes are ticked. The Rogue Rock Creek undercuts it substantially. The Honda offers hybrid efficiency and a more powerful electrified powertrain for slightly less money. The Toyota also leans on hybridization and carries the kind of resale-value hard hat that tends to make buyers feel safe and rational inside. And the Subaru remains the more authentically rugged choice if your definition of “adventure” involves more than a muddy service road and a few moody snaps for the 'Gram. But the Terrain hits back in a few ways. It feels genuinely spacious and well-made. It is quiet and rides very well. Its conventional eight-speed automatic makes it nicer to drive than some CVT-based rivals. And the AT4 trim includes the stuff buyers in this category actually care about: all-terrain tires, a lifted ride height, off-road drive modes, a skid plate, recovery hooks, a tow package, the big-screen setup, and strong day-to-day comfort.So is it excellent value? Perhaps not. Does it offer acceptable value if what you want is a rugged-flavoured compact SUV that still behaves like a civilized daily driver? That's up to you. It is less compelling if your priorities are maximum power, maximum fuel efficiency, or maximum trail credibility. The Terrain AT4 lives in the overlap of those circles rather than owning any one of them outright, and therefore might cast a net that perfectly captures your individual needs more generally than one of its more focused rivals. Final Verdict: 8.1/10The 2026 GMC Terrain AT4 is not the wildest, fastest, most efficient, or most capable soft-roader in its class. Still, it is comfortable on the road, competent on light trails, easy to drive in the city, pleasantly quiet at speed, and better put together than I expected. Its off-road hardware feels capable enough to back up the image, even if its modest 6.52 inches of ground clearance makes clear that this is still a crossover first and a trail toy second. It will handle mud, ruts, potholes, and rough access roads with more confidence than many buyers will ever ask of it, but it still knows its limits.Charm is something the Terrain AT4 ended up having in greater supply than I expected. Part of that came from the obvious stuff: the handsome design, the composed ride, the sense of solidity. Part of it came from smaller moments. Chasing a drone down a riverside trail in Squamish because it was about to outrun its own battery range was the kind of ridiculous little adventure that reminds you what vehicles like this are actually designed to be ready for. So was the much less cinematic ferry-terminal run to Tsawwassen with my brother and all his gear piled in. The Terrain felt equally suited to both, with neither situation outweighing the other in what it was ready to tackle. Versatility is the word of the week here. Ultimately, the Terrain AT4 is not a fake off-roader, but it's also not quite a modern-day GMC Jimmy 4x4 (although, how cool would that be?). It is a balanced, well-executed compact SUV for people who want some real outdoor ability without turning their daily commute into a punishment. That makes it best for buyers who like the idea of adventure a little more than the fantasy of extremity. The kind of people who drive mostly in cities, bug out on weekends, hit the occasional forest road to avoid stop-and-go traffic, regularly deal with unpredictable weather, carry copious amounts of lopsided gear, and still care that their daily driver feels aptly refined. For them, the 2026 GMC Terrain AT4 is not just a credible option. It might be one of the more overlooked good ones.
