2026 GMC Sierra EV AT4: Danvers Buyers Guide
Quick Answer: 2026 Sierra EV AT4
AT4, from $79,300 MSRP, is the Sierra EV's off-road specialist — new for 2026 alongside the entry-level Elevation. It skips the Standard Range battery entirely and starts on the Extended Range pack (GM-estimated 390-mile range on this configuration), with the Max Range pack (GM-estimated 478 miles, not yet EPA-certified) available for buyers who want more headroom. Standard equipment includes 35" all-terrain tires, a 2" factory lift, 4-Wheel Steer with CrabWalk, red front recovery hooks, a 14" Head-Up Display, and Super Cruise hands-free driving with a 3-year OnStar One plan — all bundled in, not options. Max available output on AT4 climbs to 725 hp and 775 lb-ft.
The trim that skips a battery pack on purpose
Here's the detail worth knowing before configuring one: AT4 is the only Sierra EV trim that doesn't offer the Standard Range battery at all. Elevation and Denali can both be built all the way down to that entry-level pack; AT4 can't. Its lineup starts on Extended Range and moves up to Max Range, which means every AT4 on the lot carries meaningfully more battery — and more weight, and a higher base price — than the truck's siblings, by design. GMC built this trim around capability first, and the battery specification reflects that.
The Extended Range configuration on AT4 carries a GM-estimated 390-mile range figure; the Max Range pack, available on AT4 and Denali, is rated by GMC itself at 478 miles — but that number hadn't received official EPA certification as of this writing, so it's worth confirming the current status with GMC Danvers before treating it as a guaranteed figure. Charging speed also depends on which battery pack is installed, not the trim name: the Extended Range pack charges at up to 670V (up to 106 miles added in about 10 minutes on a public DC fast charger), while the Max Range pack steps up to 800V charging (up to 120 miles in about 10 minutes).
Off-road hardware that's standard, not an upgrade
AT4's off-road equipment isn't an options-list exercise — it's the trim's baseline. Every AT4 comes with 35" all-terrain tires, roughly 2 inches of additional ground clearance versus the standard Sierra EV suspension, and red front recovery hooks for actual trail use. 4-Wheel Steer with CrabWalk — letting the rear wheels turn to move the truck diagonally, useful for tight trail lines or awkward parking — is standard, as is a 14" Head-Up Display that's only an available option on the entry Elevation trim. Super Cruise hands-free driving comes standard too, bundled with a 3-year OnStar One plan, rather than the paid add-on it is on Elevation. The available AT4 Premium Package layers on a MultiPro Midgate, a Rear Camera Mirror, a Bed View Camera, and GMC's ProGrade Trailering System for buyers who tow as well as trail-drive.
What GMC Danvers buyers say
Reviews at GMC Danvers consistently name the specific people who handled the sale, and that held true for the store's first Sierra EV purchase on record: "We were greeted by the manager Eddie and helped through the entire process by Allisa... The team, I felt, was honest, trustworthy, and genuinely happy for me to get the truck of my dreams." That same straightforward, no-back-and-forth style shows up across the store's reviews regardless of which truck someone's buying — a relevant thing to know before negotiating on a $79,300 off-road electric truck.
Frequently asked questions
Does the AT4 offer a Standard Range battery?
No — AT4 is the one Sierra EV trim that skips it entirely. Buyers choose between the Extended Range pack (GM-estimated 390 miles on this configuration) or the Max Range pack (GM-estimated 478 miles, not yet EPA-certified).
What is the maximum range of the 2026 GMC Sierra EV AT4?
478 miles is GMC's own estimate for the Max Range battery pack, but that figure had not received official EPA certification as of this writing. Confirm the current certified figure with GMC Danvers before relying on it for trip planning.
Is Super Cruise standard on the AT4?
Yes, along with a 3-year OnStar One plan — both come bundled in on AT4 and Denali. It's an available option, not standard, on the Elevation.
How much more expensive is AT4 than Denali?
AT4 starts $9,600 higher than Denali — $79,300 versus $69,700 — despite Denali being GMC's traditional luxury flagship name. AT4's higher price reflects the off-road hardware and the fact that it never offers the lower-cost Standard Range battery.
Can the Sierra EV AT4 use a Tesla Supercharger?
Only with GM's NACS charging adapter — the truck's native port is CCS1, not the Tesla-style NACS connector, so Supercharger access isn't built in out of the box.
The bottom line
AT4 is the Sierra EV built for buyers who actually want the off-road hardware — the lift, the tires, the CrabWalk steering — and are willing to pay for a bigger standard battery to get it. It's the priciest of the three trims, and worth cross-shopping seriously against a similarly equipped Denali before deciding which set of standard features matters more.
MSRP figures exclude the $2,095 destination charge plus taxes, title, registration, and dealer-installed options; the dealer sets the actual selling price. Range, charging, and performance figures are manufacturer specifications and EPA data as available at time of writing; figures described as GM-estimated had not received EPA certification as of this writing and may change. Super Cruise availability depends on compatible-road mapping and vehicle configuration. Equipment and availability can shift with production timing; confirm current specs with GMC Danvers.
