2026 GMC Sierra EV AT4: Marion Buyers Guide

2026 GMC Sierra EV at Jim Cook GMC in Marion, NC

Quick Answer: 2026 Sierra EV AT4

AT4, from $79,300 MSRP, is the off-road-focused Sierra EV, and it's the most expensive trim in the lineup — pricier than Denali, GMC's usual luxury flagship. One detail catches buyers off guard: AT4 does not offer the Standard Range battery at all. It's Extended Range or Max Range only, with Extended Range's 390-mile figure being a GM estimate rather than an EPA-certified rating. Standard equipment includes Super Cruise hands-free driving (with a 3-year OnStar One plan included), 35" all-terrain tires, 2" of additional ground clearance over Elevation and Denali, red front recovery hooks, 4-Wheel Steer with CrabWalk, and a 14" Head-Up Display. The available AT4 Premium Package adds the Rear Camera Mirror, Bed View Camera, and ProGrade Trailering System. Same 2-motor e4WD as every Sierra EV trim — AT4's difference is entirely in what's underneath and around it.

Why the off-road trim outprices the luxury one

It looks backwards at first glance — AT4 at $79,300 costs more than Denali at $69,700, despite Denali being GMC's flagship luxury badge. The gas Sierra 1500 has the exact same inversion, so this isn't an EV-specific quirk. What's driving it is hardware: 35" all-terrain tires, a taller ride height, CrabWalk's 4-Wheel Steer system, and standard Super Cruise all cost real money to engineer and build, independent of how much wood trim or quilted leather ends up in the cabin. Buyers cross-shopping by trim prestige alone will get the price order wrong.

The battery-pack trap specific to AT4

Elevation and Denali can both be built with the entry-level Standard Range battery. AT4 can't — it's Extended Range or Max Range only, full stop. That's part of why AT4's starting price sits above Denali's Standard Range floor even before you factor in the off-road hardware. The Extended Range pack on AT4 is rated by GM at an estimated 390 miles (GMC has not yet published an EPA-certified figure for this specific configuration, so "GM-estimated" is the accurate way to describe it). Stepping up to the Max Range pack pushes GM's estimate to 478 miles — again, not yet EPA-certified — while output climbs to a class-leading 725 hp and 775 lb-ft on this trim.

Real off-road hardware, not badge-deep

CrabWalk, GMC's 4-Wheel Steer trick that lets the rear wheels turn opposite the fronts for tight low-speed maneuvering, comes standard on AT4. So does the 14" Head-Up Display and Super Cruise — both optional on Elevation, but included here without upcharge, along with the 3-year OnStar One plan that Super Cruise depends on. The 35" all-terrain tires and 2" of extra ground clearance over Elevation and Denali are also standard, along with red front recovery hooks that signal the trim's off-road intent before you even open the door. The available AT4 Premium Package adds the Rear Camera Mirror, Bed View Camera, and ProGrade Trailering System for buyers who tow along with using the truck off-pavement.

Terrain around Marion that actually uses this

McDowell County sits where the foothills meet the Blue Ridge, and forest roads through the Pisgah District along with the gravel stretches near Curtis Creek are close enough to the dealership to be a real consideration, not a hypothetical one. A truck with standard 35" tires, extra clearance, and CrabWalk is built for exactly that kind of terrain — and for winter driving on secondary roads that see less plowing than I-40, where the added ground clearance and e4WD's instant torque both matter in practice.

What buyers say about the dealership

Truck buyers describing their purchase at Jim Cook GMC keep circling back to the same theme — no pressure, no games. "The best dealership! Very friendly, fast and accurate service. I won't take my truck anywhere else," one reviewer wrote. Another, describing a from-out-of-state truck purchase: "The entire process was easy and smooth... he priced the truck to sell it and not put his kids through college on this one deal." No review in the dealer's current data names the Sierra EV AT4 specifically, since the trim only launched this model year, but the buying-process feedback above applies across GMC's truck lineup at this store.

Frequently asked questions

Why does AT4 cost more than Denali on the Sierra EV?

AT4's off-road hardware — 35" tires, extra ground clearance, CrabWalk 4-Wheel Steer, standard Super Cruise — is expensive to engineer and build, independent of luxury trim level. The gas Sierra 1500 has the same price-versus-prestige inversion between these two trims.

Can I get a Sierra EV AT4 with the Standard Range battery?

No. AT4 is available only with the Extended Range or Max Range battery pack; the Standard Range option is exclusive to Elevation and Denali.

Is the Max Range battery's 478-mile figure an EPA rating?

No — it's GM's own estimate. As of this writing, fueleconomy.gov has not published an EPA-certified figure for the Max Range configuration, so treat 478 miles as directional rather than an official rating.

Is Super Cruise standard on AT4?

Yes, along with a 3-year OnStar One plan. It's optional on Elevation but standard on both AT4 and Denali.

What comes in the AT4 Premium Package?

Rear Camera Mirror, Bed View Camera, and the ProGrade Trailering System.

The bottom line

AT4 is the Sierra EV for a buyer who genuinely wants off-road capability — not badge-deep styling, but real 35" tires, real clearance, and a 4-Wheel Steer system that works. The trade-offs to plan around: no Standard Range battery option, and a price that lands above Denali despite AT4 not being GMC's luxury trim.
