The GMC Yukon AT4 is the rugged, off-road-ready version of one of Canada’s most popular full-size SUVs. For 2025, it gets a refreshed design, updated tech, and more off-road capability without losing the comfort and space that make the Yukon such a strong choice for families. Sitting between the more premium Denali and the more affordable SLT, the AT4 stands out with its higher ground clearance, skid plates, and a front end designed for trail driving. With a standard V8 engine, available air suspension, and real four-wheel drive, the AT4 offers a rare mix of everyday practicality and genuine off-road readiness.
Under the hood, the 2025 Yukon AT4 comes standard with a 5.3-litre V8 that makes 355 horsepower and 383 lb-ft of torque. You can also upgrade to a more powerful 6.2-litre V8 with 420 horsepower and 460 lb-ft of torque. Both engines are paired with a smooth 10-speed automatic transmission that does a good job of keeping the Yukon moving confidently, whether you’re cruising on the highway or climbing a snowy cottage trail.
The power delivery is linear and predictable, and while the 5.3-litre engine is fine for daily driving, the 6.2-litre brings the Yukon to life. Acceleration feels strong for a vehicle this size, and the engine sound has a classic V8 rumble that adds to the truck’s character.
The AT4 comes with a standard two-speed transfer case, hill descent control, and a unique front bumper that improves the approach angle, making it more capable on rough terrain than the regular Yukon. There’s also an optional air suspension system that can raise the vehicle for better ground clearance or lower it for easier entry and exit. The system works well and adds real versatility for Canadian conditions, especially in winter or on uneven roads.
Despite its size and off-road intent, the Yukon AT4 rides surprisingly well. The chassis feels solid, and road noise is kept to a minimum. The suspension does a good job of soaking up bumps and potholes, especially with the air suspension equipped. On paved roads, the Yukon drives like a refined, comfortable SUV, with steering that’s light but accurate and brakes that feel strong and consistent.
When the road gets rough, the AT4’s upgrades make a noticeable difference. The added ground clearance, underbody protection, and off-road tires help the Yukon feel more planted and confident on gravel, dirt, or snow-covered trails. It’s not a hardcore rock crawler like a Wrangler or Bronco, but it’s more than capable enough for trips to the lake, remote campgrounds, or ski lodges.
Inside, the 2025 Yukon AT4 strikes a good balance between rugged style and upscale comfort. The cabin layout is straightforward and functional, with large buttons and controls that are easy to use even with gloves on. Materials are solid and feel premium enough for the price, especially in the higher trims.
You get a 12.3-inch digital gauge cluster and a new 16.9-inch centre touchscreen running GMC’s updated infotainment system. It’s fast, easy to navigate, and comes with Google built-in, along with wireless Apple CarPlay and Android Auto. The interface looks clean and is laid out logically, and there’s a row of physical buttons for climate and drive settings which is a nice touch.
Seats are wide and supportive, and there’s a good view of the road from the high driving position. The second row can be had with either captain’s chairs or a bench, and the third row has enough space for adults on shorter trips. Access to the third row is simple thanks to the sliding second-row seats. Heated front seats, a heated steering wheel, and tri-zone climate control all come standard in Canada, and ventilation and rear-seat entertainment are available on higher trims.
The Yukon AT4 offers plenty of space for passengers and gear. Even with all three rows in use, there’s usable cargo room behind the third row, and folding the seats down opens up a flat load floor. For families who need more space, the Yukon XL version is available and stretches the cargo area significantly.
Towing capacity is also strong. With the 6.2-litre V8 and the Max Trailering Package, the Yukon AT4 can tow up to 8,200 pounds, which is more than enough for most campers, boats, or trailers. The trailer tech package includes features like trailer side blind zone alert, trailer brake controller, and hitch guidance with a rear camera view that makes hooking up easier and safer.
GMC includes a solid set of safety features as standard. Forward collision alert, automatic emergency braking, lane keep assist, and blind spot monitoring are all included. The AT4 also comes with front and rear parking sensors, rear cross-traffic alert, and a high-definition rearview camera.
For 2025, the Yukon now offers optional Super Cruise on higher trims, but it’s not standard on the AT4. Even without it, the available surround-view camera, head-up display, and adaptive cruise control all add to the feeling of safety and confidence, especially on longer drives or in traffic.
The 2025 GMC Yukon AT4 is a great fit for Canadians who want a full-size SUV that can do it all. It’s comfortable and refined enough for family road trips, yet tough and capable when the road disappears. The available V8s give it the strength and sound buyers expect, and the updated tech and spacious interior make it feel modern and easy to live with.
It’s not the most luxurious trim in the Yukon lineup, and it’s not trying to be. What the AT4 offers is a well-rounded package with real off-road ability, great towing capability, and all the space you need for daily life or weekend adventures. If you want a vehicle that can handle the backroads of Muskoka just as well as it can handle downtown traffic, the Yukon AT4 hits the mark.
That said, there are a few trade-offs to consider. Fuel economy is average at best, especially with the larger V8, and you’ll be visiting the gas station often if you do a lot of city driving. The AT4’s off-road tires and taller suspension can also make the ride a bit firmer than other Yukon trims, especially on rough pavement. And while the cabin is well-equipped, some interior materials still fall short of what you’d find in similarly priced luxury SUVs.
Still, if you want a full-size SUV that balances comfort, capability, and rugged looks, the Yukon AT4 remains one of the most appealing choices in its segment.
