If not for its width and weight, the 2024 GMC Hummer EV SUV can be essentially the most off-road-capable passenger car direct from the manufacturing facility on sale as we speak. It climbs extra assuredly than a inventory Wrangler Rubicon or Bronco Raptor, it negotiates obstacles extra simply and extra safely than a Rivian R1S, and don’t even come at me with a Cyberfridge. But when not for the width and weight of the proverbial elephant within the room, you’d have one thing else solely.
Girth and weight usually are not off-road benefits. At 86.5 inches huge, the Hummer EV SUV classifies as huge sufficient to legally require three amber lights on the high of the car in entrance, and three in purple within the rear, identical as what’s federally mandated for semis, dump vans, and different heavy haulers. At about 9,000 kilos, give or take just a few hundred, the GMC Hummer EV SUV shares an EPA classification with heavy responsibility pickup vans.

I didn’t see one pickup truck, heavy responsibility or in any other case, navigating the slickrock outdoors Moab, Utah, on the rocky cabinets and sandy washes of Jax Trax, beneath the auspices of the snow-capped La Sal Mountains. A small convoy of enormous Hummer EV SUV 3Xs negotiated an earthly airplane the place rock formations frozen in time kind pure bridges and dystopian mesas loom over desert valleys, like one thing out of Tatooine or Arrakis.
Someplace on the market, someplace in right here, within the geological frieze of southeastern Utah between Arches and Canyonlands Nationwide Parks, the place the Highway Runner and Coyote have been born, I didn’t hear any meep-meep zip-tang. The silence of off-roading an EV envelops you within the pure world as an alternative of estranging you from it as in a combustion car, a conqueror vanquishing its pure foe.
The gasp of the air suspension, the caw of a hawk, the hum of the HVAC, the whisper of a breeze, the squish of rocks beneath the Goodyear Wrangler 305/70R18 35-inch mud-terrain tires, the sun-baked earth pushing again—that’s all there was, till the tip.
Late within the day, on this place that is aware of no human time, the buzzsaw of combustion engines broke the otherworldly serenity. Two side-by-sides—open cages, tube chassis, made for off-roading, unlawful close to civilization—killed their engines and waited for the EV mastodons to cross. At the back of the primary side-by-side have been two little one security seats, toddlers in goggles, googling on the future.
We have been in shock of one another. So it goes for interplanetary passersby.

2024 GMC Hummer EV SUV 3X on-road dealing with
Not like the films and cartoons, we didn’t simply get dropped into our desolate magnificence. I drove the 2024 Hummer SUV EV 3X from Grand Junction, Colo., into Moab, Utah, winding alongside the Colorado River, that nice imperiled gateway to southwestern dwelling.
This wasn’t the primary time I examined or GMC hosted an occasion for the 2024 GMC Hummer SUV EV. In March 2023, GMC hosted a program in Napa Valley, the place report rainfall soaked a parched Earth that solely a 12 months earlier than had been scorched by wildfire. With sufficient rainfall in weeks to fill reservoirs that had been barren for years in the course of the drought, it was unimaginable to off-road.
The reborn Hummer EV SUV appears extra the a part of the previous Hummer than the Hummer EV pickup truck. The wheelbase is 8.9 inches shorter, and it’s 20 inches shorter in size, prompting GM to nip and tuck the 24-module battery setup of the 205-kwh pack within the truck all the way down to a 170-kwh battery pack utilizing 20 modules stacked 10 and 10 within the ladder body. From the C-pillar ahead it’s the identical because the pickup, and with the rear wheels close to the swinging tailgate, it has higher departure and breakover angles than the truck.

The massive bulldog on 22-inch wheels let in loads of street and tire noise, even when the sound past the firewall was absence. The vary beats authentic estimates to 314 miles, however like its namesake, it’s the least environment friendly EV accessible. I used to be pleased to get 1.2 miles per kwh in largely freeway and rural driving.
The Watts-To-Freedom mode nonetheless rips, rocketing the bulldog to 60 mph in an absurdly unbelievable 3.5 seconds. I used to be gleefully if not stupidly reminded that no passenger car this massive strikes that shortly. A 3-motor system producing 830 hp and 1,200 lb-ft of torque can do this. WTF lowered the air suspension from 10.1 inches to about 6.5 inches of floor clearance, firmed up the damping, and pinned me in my seat.

One other nice reminder on the street was how all 5 modes, together with a My Mode setting, flashed a distinct model of lunar graphics as sharp as PC gaming graphics into the 13.4-inch touchscreen and adjoining 12.3-inch instrument cluster. Any automaker intent on growing an intuitive interface that doesn’t sacrifice performance for flashiness, test it out; that’s you, Mercedes.
I additionally appreciated how GMC balances the interface with futuristic graphics and traditional toggles and dials for the local weather, drive modes, and different car capabilities.
An disagreeable reminder was how poor the outward imaginative and prescient was, regardless of the commanding trip top. The squat greenhouse features a windshield so huge and quick that it required three small windshield wipers to clear away rain. Regardless of all of the technological innovation, a head-up show wasn’t provided as a result of there’s nowhere secure to undertaking it. Eradicating the t-tops and stowing them within the frunk can be the best way to open up the outward imaginative and prescient and take in all the pure magnificence alongside the Colorado.

2024 GMC Hummer EV SUV navigates Moab off-road
In some way, all of the engineering wizardry that thrums beneath the floor on the freeway turns into foremost when off-roading, primarily shrinking and lightening the Hummer SUV’s huge presence.
For the tour, I stepped up into the Excessive Off-Highway bundle, which is $9,995 additional on the 3X ($4,995 on Version 1) and greater than half of Hummer EV SUV consumers go for it. They need to.
Along with the 18-inch wheels and mud-terrain tires, it deletes the rear stabilizer bar; provides 4 extra skid plates to cowl the entrance motor, the rear motor, and two skid plates overlaying the battery pack; has two further underbody cameras with washers to take a look at what’s beneath the entrance axle and rear axle; and it has rock rails with inbuilt help steps, the higher to step up into the Hummer, particularly when it’s in full extract mode at 15.9 inches of floor clearance.
Fortuitously, I and nobody else on my wave had to make use of extract mode or Crab Stroll to regain the path. The closest it got here was descending down a steep, perhaps 25-degree shelf right into a flip round an outcropping. With the entrance central locker on and digital rear locker engaged by way of the 2 rear motors, wheel slip was managed, even with the entrance driver wheel hanging within the air. However as all 4 wheels stair-stepped down the shelf into the flip, the driving force cranked the wheel and held the brake; that entrance driver-side wheel plowed into the unfastened sand and looser rock that had come dislodged from the earlier driver. A small rock slide ensued; the heavy Hummer slid with it, initially.

GMC’s off-road instructors by no means wavered or nervous. That included GMC Hummer EV lead growth engineer Aaron Pfau, who later admitted to me that it was nowhere near perilous, and the Hummer had so many methods left up its raised sleeves, earlier than even contemplating Crab Stroll or Extract mode. When the slide and car stopped, the Hummer’s rear-wheel steering bumped the rear round because the entrance wheels scrabbled out of the slide. The drive mode dealt with the correction greater than the driving force.
Off-Highway mode acts extra like a high-speed baja mode with much less traction management and the equal of open lockers. I largely saved it in Terrain mode that raises the suspension from 10.1 to 11.9 inches, amongst many different issues. Choosing both of these two modes on the dial within the console triggers a type of 2-factor authentication from the touchscreen; nobody likes 2-factor authentication and initially it was simple to neglect to push the affirmation display screen till realizing Regular’s mode limitation on the path.
The wonderful graphics on the touchscreen present pitch and roll meters, in addition to the mode setting and different data like altitude. However more often than not off-roading, I had it set to show the wonderful digital camera angles–as much as 17 of them—that gave me eyes in entrance, again, beneath, round, and from above. These additional eyes helped measurement the car in my thoughts’s eye, however it was the rear-wheel steering at as much as 10 levels counterphase, or reverse of the entrance wheels, that actually opened my eyes to how GMC shrinks the Hummer SUV.
It primarily brings the rear-end round hairpins and different turns faster and cleaner. It additionally aids with grip, with extra wag from the rear to get unstuck earlier than getting caught is an choice. Initially, GMC calibrated the rear wheels to show at a ratio of 1.5:1 of the entrance wheels, however the wag was so huge it might’ve shocked drivers in too nice a means and result in overcorrection. As an alternative, GMC settled for a ratio of 1.2:1, so not solely does it shrink the turning circle however it makes that bulldog in a position to deftly sidewind out and in of obstacles and, if wanted, use all 4 wheels to steer out of a sand pit.
Many luxurious and efficiency vehicles have adopted rear-wheel steering, however GMC’s off-road software in tandem with the fixed and immediate torque vectoring from the three motors made it subsequent degree. The entrance locker could be manually engaged with a protracted press of the locker button on the panel beneath the touchscreen (and it’ll mechanically disengage over 25 mph), however the drive modes largely maintain all of the settings.

I most well-liked shifting the gear shifter from D to L for the max regenerative braking. This enabled me to brake with my left foot and throttle with my proper each up and down slopes to maintain the wheels shifting however not enable the SUV to maneuver an excessive amount of. Simply leaving it in L, the place beneath 5 mph the mode makes use of all friction braking, resulted within the type of jerkiness which may have made me go off the throttle solely and lose momentum.
There’s a lot happening in any respect 4 corners, however all I needed to do was level and go, actually. It made me a greater off-roader, and all of it felt seamless, nearly pure.
That’s intentional. Because the drive a 12 months in the past in 2023, GMC made about two dozen enhancements to the management modules and calibration to the off-road techniques.
“When you might have the infinite variability of an off-road electrical car, there are much more changes to make,” Pfau informed me. “Determining the physics drawback of the place the torque must go when you might have slip with three motors is a problem, as an alternative of say a switch case with a central entrance and rear locker, the place mechanically it’s gonna discover the slip. It takes time to deeply analyze how we’re sending torque on the subject of ones and zeroes.”
Right here’s some not-zeroes: The 3X prices $106,995, together with an industry-leading $2,295 vacation spot payment. Add the Excessive Off-Highway bundle (it is best to) and it’s $116,990. There are far costlier and much much less succesful toys.
Off-roading for seven hours over a 16-mile path with an elevation change of greater than 2,500 toes, and driving about 85 miles there and again, by no means as soon as amounted to vary nervousness. I had 124 miles of vary remaining from the 295-mile begin.
Out right here, in the midst of nowhere, the Hummer EV SUV flexed all of the revolutionary EV know-how that not solely shrinks its width and offsets its weight, however demonstrates what the subsequent period of off-road automobiles can aspire to.
Bundle all these options along with all the opposite capabilities of the Hummer EV SUV and there’s really no different car from the manufacturing facility prefer it. Its silence beneath extraterrestrial pressure is simply one other bonus.
GMC paid for airfare and lodging for us to dispatch these impressions from afar.
