- The 2026 GMC Hummer EV lineup includes a new Carbon Fiber Edition.
- The fastest-ever Hummer accelerates from 0-60 mph in 2.8 seconds.
- The EV also gains a new King Crab mode for improved maneuverability.
Even the most excessive EV on the market is still getting upgrades. For the 2026 model year, the GMC Hummer EV sees a series of small updates aimed at enhancing performance, off-road functionality, and overall refinement. A few of the improvements will even be offered retroactively to current owners, thanks to over-the-air updates.

}

Carbon Fiber Edition For Extreme Acceleration
Among the changes, the limited-run Carbon Fiber Edition stands out. Available for both Pickup and SUV versions, this trim builds on the top-tier 3X model but pushes performance even further. The truck version now launches from 0 to 60 mph (0–97 km/h) in just 2.8 seconds, down slightly from the already eye-widening “approximately 3 seconds” claimed by the outgoing model.

According to GMC, this extra boost is the result of refined propulsion calibration, updated software, and some hardware tweaks. The updated 3X also comes with a 24-module battery pack delivering 1,160 hp (865 kW / 1,176 PS), up from the previous 1,000 hp (746 kW / 1,014 PS).
Visually, the Carbon Fiber Edition gets 22-inch carbon fiber wheels, carbon accents on the mirror caps and skid plates, and an exclusive matte Magnus Gray exterior paired with black emblems. Inside, it features a Velocity Ember interior theme. GMC doesn’t mention any actual weight savings from the carbon fiber bits, which serve more aesthetic than functional purposes
Subtle Updates, Smarter Tech
Outside of the special edition, the 2026 Hummer lineup doesn’t get major styling revisions. However, two new exterior color options called Coastal Dune and Auburn Matte, have been added, along with new interior themes: Granite Drift and Stealth Eclipse.
var adpushup = window.adpushup = window.adpushup || {que:[]};
adpushup.que.push(function() {
if (adpushup.config.platform !== “DESKTOP”){
adpushup.triggerAd(“bb7964e9-07de-4b06-a83e-ead35079d53c”);
} else {
adpushup.triggerAd(“9b1169d9-7a89-4971-a77f-1397f7588751”);
}
});
The tech front gets a more noticeable upgrade. The 13.4-inch infotainment screen now supports a customizable split-view layout, giving drivers quicker access to key data. The Super Cruise driver assistance system has also been updated, though details on those improvements are still limited
King Crab Mode For Everyone
Another highlight of the 2026 MY is the addition of the King Crab mode. This feature is standard in the 2X and 3X trims and will be available to all Hummer EV Pickup and SUV owners later this year through an over-the-air update. According to the company, the King Crab mode makes the rear wheels turn “significantly faster” than the front wheels, improving maneuverability in tight spaces and enhancing the rock crawling abilities of the Hummer.

GMC engineers have also optimized the damper tuning of the EV, promising an improved ride quality. Furthermore, all versions of the Hummer are now compatible with bidirectional charging, meaning they can charge another vehicle, or power your entire home during a blackout.
Production of the 2026 GMC Hummer EV Pickup and SUV will take place at GM’s Factory ZERO Assembly Center in Michigan. The updated models are expected to hit U.S. dealerships later this year, with pricing and range details to be announced closer to launch, likely by late summer 2025.
