2025 GMC Yukon AT4 Redesign, Reviews, MPG

2025 GMC Yukon AT4 Redesign, Reviews, MPG  –  Other than minivans, relatively few three-row vehicles truly are viable for adult passengers in the third row. One that is – and especially now thanks to a redesign – is the 2025 GMC Yukon. A longer wheelbase and a new independent rear suspension gives this big SUV even more legroom for that rear row, along with more cargo space.

I had the standard Yukon, though it’s also available as the extended-length Yukon XL, both of which are mechanical twins to the Chevrolet Tahoe and Suburban. The Yukon comes in two trim levels in rear-wheel drive, starting at $57,998, and a quartet of four-wheel-drive trims, beginning at $61,298. I had the AT4, a name GMC reserves for trucks and sport-utes with extra off-road-specific features. It starts at $74,698, while mine was garnished with several options that took it to a very hefty $86,833 before freight and taxes.  2025 GMC Yukon AT4 Redesign

2025 GMC Yukon AT4 Redesign and Update Plan

Exterior and Interior

For most needs, the Yukon is practicality on the hoof. There is a great deal of small-item storage up front, including a huge open cubby and a deep console bin. At the back, the large tailgate opens to a low liftover, so it’s relatively easy to reach in to deposit or retrieve cargo. The rear glass also flips up separately. My tester had an adaptive air suspension that could be set to automatically lower when the Yukon was in park, making it even easier to access.

There’s a shallow bin under the floor, and the second- and third-row chairs fold flat – electrically in my tester – to form a flat floor, and you get between 722 L and 3,480 L of space, depending on what seats are up or down. If that isn’t enough, the Yukon can tow as much as 3,810 kg (8,400 lb).

2025 GMC Yukon AT4 Specs

The Yukon AT4 comes well-equipped, as it should for $75,000. The standard-features list includes auto-dimming mirrors, hands-free tailgate (with an emblem projected onto the ground to show you where to kick your foot to activate it), automatic high-beam headlights, and rain-sensing wipers. Inside, you get 12-way power-adjustable heated and ventilated front seats, heated second-row chairs, power-folding third row, 120-volt power outlet, and my favourite feature, a heated steering wheel. The 10.2-inch centre touchscreen includes OnStar, a Wi-Fi hotspot, and satellite radio.  2025 GMC Yukon AT4 Redesign

That’s only the start, of course, and among other items I had an AT4 Premium Plus package, for an additional $9,795 that added such features as a maximum trailering package, dual-screen rear-seat entertainment system, panoramic sunroof, power running boards, and a “Premium Capability” package with electronic limited-slip differential and adaptive air suspension.

Engine and Performance

I’ve driven both engines, and while the 6.2L gives you more bragging rights, the smaller V8 more than gets the job done. It’s got a lot of Yukon to move around, but it’s quiet and smooth, and has more than enough acceleration for highway passing. GM uses cylinder deactivation, which shuts off fuel to portions of the engine when full power isn’t required for better mileage. Some engines have active fuel management (AFM), which shuts off the same cylinders each time, but the Yukon’s two engines use dynamic fuel management (DFM), which shuts them off in a number of different patterns, depending on what’s most efficient. It’s absolutely seamless and has no detrimental effect on performance.  2025 GMC Yukon AT4 Redesign

Size matters, and the redesigned Yukon’s extra length ups this comfortable truck’s game. Its first- and second-row chairs were always nice, and while you’ll still want to prioritize those for your own seat, the third row gets much better. That’s partly due to the extra legroom afforded by the stretch, and to the independent rear suspension in place of the previous solid axle. That lowers the rear floor, which in turn means your chin is farther away from your knees back there. The front seats are bolstered and supportive, and in the AT4 are both heated and ventilated. You can also select whether to heat the entire seat or just the seatback, which is nice if you’d like some warmth on a sore spine but don’t need your butt cooked as well.

2025 GMC Yukon AT4 Fuel Economy

The Yukon with 5.3L V8 is rated by Natural Resources Canada (NRCan) at 14.3 L/100 km in the city, 11.8 on the highway, and 13.1 L/100 km in combined driving. That’s a slight improvement over the last-generation 2020 Yukon, rated at 13.8 L/100 km in combined driving. In real-world driving, I got 13.9 L/100 km in my week with it.  2025 GMC Yukon AT4 Redesign

2025 GMC Yukon AT4 Safety Features

Neither the United States National Highway Traffic Safety Administration (NHTSA) nor the Insurance Institute for Highway Safety (IIHS) had crash-tested the 2025 makeover at the time of this writing, so I’m basing my score on what’s available in it. Standard equipment includes blind-spot monitoring, lane-keep assist, emergency front braking with pedestrian detection, rear pedestrian alert, and the rearview camera that’s mandatory on all new vehicles.  2025 GMC Yukon AT4 Redesign

2025 GMC Yukon AT4 Price and Release Date

At a starting price of $61,298 with four-wheel drive, the Yukon offers a lot of features but it’s still a hefty chunk of change. Even so, getting into some of its full-size, body-on-frame competitors will take even more out of your wallet, depending on how you check off your options list. The Nissan Armada starts at $66,098, the Toyota Sequoia at $69,790, and bring $92,500 if you want a Lincoln Navigator.

Those prices are no doubt why so many people are getting into unibody three-row sport-utilities – the Kia Telluride, for example, starts at $44,995 – along with the better fuel efficiency of these lighter-weight machines. But for those who want the Yukon’s interior space, or its towing and payload capacity, you still get a lot for your money.  2025 GMC Yukon AT4 Redesign
