Tri-motor's absurd acceleration, available removable roof is like T-tops for the whole family, tons of neat tech.

This super SUV is super pricey, some cabin materials feel low-rent, loading cargo requires a big lift.

Overview

Now under GMC's stewardship, the Hummer brand is not shy about being extra. As such, the Hummer EV SUV goes big in some notable ways: mega horsepower numbers, tons of ground clearance and suspension travel, and a heap of tech features aimed at serious off-roading. Plus, everything about it simply looks imposing. Riding on a shorter wheelbase than its pickup sibling, the EV SUV is made even more maneuverable with four-wheel steering that enables the trick CrabWalk mode, which also has benefits when parallel parking. With range estimates topping out above 300 miles, this five-seat SUV has the ability to charge up quickly and plenty of juice to take the path less taken or handle a long road trip—if you can resist the urge to floor it everywhere.

What's New for 2026?

The big news for the 2026 Hummer EV SUV is more power (as if it needed it), but we don't yet know how much more. While the Hummer EV Pickup 3X's output jumps to 1160 horsepower from an even 1000, GMC hasn't released power figures for the 3X SUV, which currently sits at 830 horsepower. The 2026 Hummers get a new four-wheel-steering mode called King Crab that's supposed to enhance off-road maneuverability. And because the new feature is implemented in software, it can be added to prior-year Hummer EVs through an over-the-air update. GMC is also adding a Carbon Fiber Edition with—you guessed it—carbon-fiber exterior trim as well as full-carbon wheels that help drop the claimed 60-mph time to 2.8 seconds. It's available on the 3X trim and comes only in Magnus Gray Matte paint with a Velocity Ember interior color scheme. The updated Hummers are also now capable of bidirectional charging, targeting either another vehicle or a home.

C/D Expert Tip:

If this year's model is largely unchanged and you're comfortable with a lightly used car, you may want to consider shopping previous model years. A one-to-three-year-old model will likely have a warranty and it'll cost less than buying new.

EV Motor, Power, and Performance

The EV2X has a dual-motor setup that generates 570 horsepower and what GM claims is 7400 pound-feet of torque. The EV3X has a trio of motors (one up front and two out back) with a claimed 830 ponies and 11,500 pound-feet. However, we've already explained why those incredible torque claims are misleading. Compared with the pickup truck, the SUV has a shorter wheelbase (126.7 inches versus 135.6), which should make it more maneuverable in parking situations and out on the trails. It also inherits our favorite off-road goodies from the truck version, including four-wheel steering with CrabWalk and an adjustable air suspension with Extract mode that can raise it six inches. GMC also pulls at our heartstrings with a full-size spare tire mounted on the rear gate. Plus, there's an optional Extreme Off-Road package that brings special hardware that includes 18-inch wheels on 35-inch all-terrain tires, extra underbody protection, low-mounted cameras for improved visibility while maneuvering, enhanced axles with heavy-duty components, a locking front differential, and rear motors that can electronically mimic a locked diff.

0–60-MPH Times

In our testing, the most powerful Hummer EV SUV hit 60 mph in 3.4 seconds, which is seriously quick for any machine, let alone one this big and heavy. It’s likely to get even quicker thanks to the as-yet-undisclosed power boost coming for the 2026 3X model, especially if it's the new Carbon Fiber Edition fitted with composite wheels.

Range, Charging, and Battery Life

The EPA estimates the Hummer EV SUV can go for up to 315 miles between charges, but adding optional mud terrain tires drops that estimate down to a max of 289 miles. We only saw 250 miles of range from its 170-kWh battery pack in our 75-mph highway test. Recharging can be quick, however. The SUV’s 800-volt architecture gains 100 miles of range in 14 minutes using a DC fast-charger. In our testing, the Hummer SUV required 128 minutes to charge from 10 to 90 percent and averaged a pull of 78 kilowatts. Otherwise, GMC says that a level 2 charger recharges at up to 19.2 kilowatts, providing 30 miles of range in an hour.

Fuel Economy and Real-World MPGe

The EPA hasn’t released any fuel economy information for the 2026 Hummer EV SUV yet, but the most efficient 2025 model earned ratings of 59 MPGe city, 46 MPGe highway, and 53 MPGe combined. In our testing, the Hummer EV SUV managed 45 MPGe highway. MPGe stands for miles per gallon of gas equivalent, an EPA metric that estimates PHEV and EV vehicle fuel efficiency.

Interior, Comfort, and Cargo

The interior of the Hummer EV SUV is part rugged and part sci-fi. Its three-dimensional dashboard boasts both vertical and horizontal air vents and a pair of large displays that include a 12.3-inch digital gauge cluster. Rather than frustrate users for the sake of appearances, the Hummer has lots of hard buttons and physical switchgear, including a thick T-shaped shifter and a rotary drive-mode selector on the center console. Some interior materials feel a bit too utilitarian; those lower down on the dash and door panels look and feel out of place in a vehicle this expensive. Another defining feature of the Hummer's cabin is its available removable roof panels. Called the Infinity Roof, the system allows users to lift off the four transparent Sky Panels and the I-bar above the front-seat passengers. Along with storage under the load floor, the SUV Hummer boasts an expansive 82 cubic feet of cargo space with the rear seat folded, but the high cargo floor makes it tough to load heavy items. In our testing, we fit 15 carry-on suitcases in the Hummer EV SUV's cargo bay; with the rear seats folded, we fit a total of 33.

Infotainment and Connectivity

The Hummer's cutting-edge electric technology is complemented by a large 13.4-inch touchscreen infotainment system and extensive connectivity options. The system can handle navigation, both on- and off-road. A 14-speaker Bose sound system comes standard, as does a subscription-based Wi-Fi hotspot and a wireless smartphone charging pad. The SUV Hummer is also available with a 6.0-kW onboard generator that can be used to power all sorts of equipment and even charge other EVs.

Safety and Driver-Assistance Features

The Hummer EV SUV comes with an enhanced version of GM's Super Cruise hands-free driving system, as well as a host of driver-assistance technology that currently graces many mainstream models. For more information about the GMC Hummer EV SUV's crash-test results, visit the National Highway Traffic Safety Administration (NHTSA) and Insurance Institute for Highway Safety (IIHS) websites. Key safety features include:

Standard forward-collision warning and automated emergency braking
Standard lane-departure warning and lane-keeping assist
Standard adaptive cruise control

Warranty and Maintenance Coverage

The Hummer EV SUV comes with a similar warranty to other General Motors products, which means three-year/36,000-mile bumper-to-bumper coverage and five-year/60,000-mile powertrain coverage.

Limited warranty covers three years or 36,000 miles
Powertrain warranty covers five years or 60,000 miles
Battery components are covered for eight years or 100,000 miles
Complimentary maintenance is covered for the first visit
