2026 GMC Yukon AT4 & AT4 Ultimate: Danvers Buyers Guide
Quick Answer: 2026 Yukon AT4 & AT4 Ultimate
AT4 starts the off-road half of the Yukon range at $76,600 MSRP with the 355-hp 5.3L V8, standard four-wheel drive (AT4 doesn't come any other way), a high-approach front fascia with skid plate and recovery hooks, 20-inch wheels on all-terrain tires, and standard Magnetic Ride Control. AT4 Ultimate starts at $97,900 and swaps in the 420-hp 6.2L V8 standard, Super Cruise hands-free driving with a 3-year OnStar One plan, Obsidian Rush full-grain leather, standard Air Ride Adaptive Suspension, and a Bose 18-speaker system. Both are built for the same job: a full-size SUV that can launch a boat at a sandy Cape Ann ramp, climb an unplowed driveway in January, and still seat eight on the way home.
Four-wheel drive isn't an option here — it's the point
Every other Yukon trim treats 4WD as a checkbox. AT4 and AT4 Ultimate don't offer anything else: no rear-wheel-drive version exists on this trim, full stop. That's paired with a front fascia designed for a steeper approach angle, a genuine skid plate, red recovery hooks that aren't just cosmetic, and 20-inch wheels wrapped in all-terrain rubber instead of highway tires. Magnetic Ride Control — GMC's suspension system that reads the road up to 1,000 times a second — is standard on both AT4 trims, which matters as much on a frost-heaved North Shore back road as it does off pavement.
The AT4-to-AT4-Ultimate step changes the engine, not the off-road hardware: base AT4 runs the 5.3L V8 standard with the 6.2L V8 as an option, while AT4 Ultimate makes the 6.2L standard. AT4 Ultimate also adds Super Cruise (with a 3-year OnStar One plan bundled in), standard Air Ride Adaptive Suspension on top of the Magnetic Ride Control, 16-way power front seats with massage, and Obsidian Rush full-grain leather with AT4 Ultimate badging. The bigger speaker count — 18 versus the standard system — comes with it too.
What the North Shore actually asks of a truck like this
This isn't marketing off-roading; it's regular life up here. A boat trailer down a wet ramp at Cape Ann or Plum Island. A driveway on a hill in Beverly or Marblehead that the plow gets to last. The seasonal camp road that turns to washboard gravel every spring thaw. AT4's standard 4WD and Magnetic Ride Control are built for exactly that kind of unglamorous, recurring demand, not a one-time trailhead.
Who buys an AT4 here
Owners hauling boats, campers, or trailers who want standard 4WD without stepping up to Denali money. Buyers who want the truck's mechanical capability more than its interior polish. GMC Danvers' reviews reflect the truck-buyer crowd this trim attracts — commercial and multi-vehicle owners as much as families. One longtime customer summed up the relationship: "I have serviced my entire fleet as well as my personal vehicles here for years. Colby in service is honest and easy to deal with." Another, on a straightforward sales experience: "Manny was a great salesperson and so was the sales managers, Niko and Eddie. The service at [GMC Danvers] was excellent."
If Obsidian Rush leather, Super Cruise, and the bigger Bose system matter more to you than the base AT4's price, the Ultimate is a clean step up on the same off-road bones. If you'd rather have Denali's on-road luxury focus without the off-road hardware, see the Denali guide instead.
Frequently asked questions
What does the 2026 Yukon AT4 cost?
AT4 starts at $76,600 MSRP and AT4 Ultimate at $97,900, both before GMC's $2,795 destination charge, Massachusetts' 6.25% sales tax, registration, and the annual excise. The pricing guide covers the rest, and current GMC Danvers specials apply against these MSRPs.
Is AT4 available with rear-wheel drive to save money?
No. AT4 and AT4 Ultimate are both four-wheel-drive only; there's no 2WD/RWD configuration on either trim. If a lower price point with RWD available matters more than the off-road hardware, the Elevation or Denali are the trims to look at.
What engine comes standard on the AT4?
The 5.3L V8 (355 hp / 383 lb-ft) is standard on base AT4, with the 6.2L V8 (420 hp / 460 lb-ft) available as an upgrade. AT4 Ultimate makes the 6.2L V8 standard.
Does the AT4 get the same infotainment and safety tech as other trims?
Yes — the 16.8-inch Premium GMC Infotainment System and the Yukon's core safety suite aren't trim-gated. AT4 Ultimate adds Super Cruise hands-free driving standard; it's available (not standard) on the base AT4.
Where can I see an AT4 in person?
Check current AT4 inventory at GMC Danvers, or start with the dealer's trade valuation tool if you're rolling a trade into the deal.
The bottom line
AT4 is the Yukon built for people who actually use 4WD, not just check the box for it — standard on every AT4, backed by real off-road hardware and a suspension tuned for rough surfaces year-round. Ultimate adds the luxury layer on top without touching the mechanical bones. Either way, it's the North Shore's boat-ramp-and-back-road trim.
