Honestly, the 2025 GMC Hummer EV SUV 3X is a bit of a rolling contradiction. You’ve probably seen the videos of it doing the "CrabWalk" or heard about the insane 0-60 mph times that make supercars look slow. But there is a massive difference between the marketing hype and what it’s actually like to live with this 9,000-pound electric beast.
Most people assume it’s just a bigger, dumber version of a Tesla. It isn't. Not even close.
While a Rivian R1S or a Tesla Model X feels like a "tech product" that happens to be a car, the Hummer EV SUV 3X feels like a piece of heavy machinery that accidentally got a 13.4-inch touchscreen. It is loud, it is wide, and it is unashamedly excessive. But if you’re looking at the 2025 model, there are some specific tweaks and real-world quirks you need to know before you drop six figures at a dealership.

The Tri-Motor Reality: 830 Horsepower is Overkill (and We Love It)
Let’s talk about the heart of the 3X trim. Unlike the 2X, which "only" gives you two motors, the 3X uses three—one up front and two in the back. GMC claims this setup pumps out 830 horsepower and a theoretical 11,500 lb-ft of torque.
Hold on a second.
That torque number is a bit of a marketing trick. That’s "wheel torque," which is multiplied by the gears. In terms of actual motor torque—the kind of number you’d compare to a gas engine—it’s closer to 1,200 lb-ft. Still, that is enough to make this house-sized SUV lunge forward with a violence that genuinely scares passengers.
Watts to Freedom (WTF)
If you engage "Watts to Freedom" mode—yes, the acronym is intentional—the car actually lowers itself, vibrates the seat to let you know it’s ready, and then rockets from 0 to 60 mph in about 3.5 seconds.
I’ve seen people lose their phones, their hats, and their dignity during a WTF launch. It’s not just fast; it’s physically confusing to feel that much mass move that quickly.
What’s Actually New for 2025?
GMC didn't reinvent the wheel for the 2025 model year, but they did prune the lineup. They killed off the Omega Limited Edition, which was basically just a fancy paint job, to focus on making the 3X more consistent.
- Fresh Paint: You can now get it in Solar Orange or Graphite Blue Metallic. These replace some of the older, flatter colors like Tide Metallic.
- Software Snappiness: The 2024 models had some "laggy" complaints regarding the infotainment. The 2025 version feels a bit crisper, though it still relies heavily on Google Built-in.
- Super Cruise Upgrades: The hands-free driving tech now covers over 750,000 miles of North American highways. It’s arguably the best hands-free system on the market right now, especially with the 2025 software tweaks that make lane changes smoother.
The "Efficiency" Elephant in the Room
If you’re buying a Hummer to save the planet, you’re doing it wrong. This thing is basically a brick with a battery.
The 2025 GMC Hummer EV SUV 3X gets an EPA-estimated 312 miles of range. That sounds decent until you realize it takes a massive 212 kWh battery pack to get there. To put that in perspective, you could almost power three smaller EVs with the amount of lithium stuffed under the floorboards here.
In real-world driving, especially if you have a lead foot or it’s cold outside, expect that number to dip. However, the 800-volt DC fast charging is a lifesaver. If you find a 350 kW charger, you can add about 100 miles of range in 12 minutes. You'll need it, because the Hummer's efficiency is roughly 50-53 MPGe—roughly half as efficient as a Lucid or a Tesla.
Off-Roading: More Than Just a Gimmick?
The 3X comes standard with CrabWalk. By turning the rear wheels up to 10 degrees in the same direction as the front, the SUV moves diagonally. It’s cool for showing off at stoplights, but on a tight trail, it actually helps you shimmy around rocks that would normally scrape your doors.
Extract Mode
Then there’s Extract Mode. Using the air suspension, the Hummer can lift itself a full 6 inches. This gives you roughly 16 inches of ground clearance. That is more than a Ford Raptor or a Jeep Wrangler Rubicon.

Expert Tip: If you’re serious about the dirt, get the Extreme Off-Road Package. It swaps the 22-inch wheels for 18s wrapped in 35-inch Goodyear Wrangler Territory MT tires and adds underbody cameras (UltraVision) so you don't smash your battery on a boulder.
The Interior: Rugged or Just Cheap?
This is where the 2025 GMC Hummer EV SUV 3X loses some people. When you pay $105,000 to $120,000 for a vehicle, you expect Mercedes-level luxury.
You won't find it here.
The interior is "Lunar Horizon" or "Lunar Shadow"—lots of tech-bronze accents and durable-feeling plastics. It feels like a high-end lunar rover. It’s meant to be hosed out (sorta) and stand up to muddy boots. But compared to a Range Rover, there’s a lot of hard plastic.
The Infinity Roof is the saving grace. The four transparent "Sky Panels" are removable, turning the SUV into a semi-convertible. They store in the frunk (front trunk), which is great until you realize that once the panels are in there, you have zero room for groceries.
Is the 3X Right for You?
The 3X is the sweet spot of the lineup if you want the full Hummer experience. The 2X is fine, but it lacks the "holy crap" factor of the tri-motor launch.
Buy it if:
- You want the most "present" vehicle on the road.
- You actually go off-roading and need 16 inches of clearance.
- You love the idea of hands-free highway driving with Super Cruise.
Skip it if:
- You have a narrow driveway or a small garage (it's nearly 87 inches wide).
- You care about "miles per kWh" and energy efficiency.
- You want a "soft" luxury ride; the Hummer is comfortable but always feels heavy.
Actionable Next Steps
If you're serious about the 2025 GMC Hummer EV SUV 3X, don't just look at the MSRP. Here is how to actually move forward:
- Check Your Garage: Measure your garage door width. Most standard doors are 96 inches. With the mirrors out, the Hummer is over 93 inches wide. It is a tight fit.
- Verify Charger Access: You need a Level 2 charger at home. Charging this 212 kWh battery on a standard 120V wall outlet would take nearly a week to go from empty to full.
- Test the Extreme Off-Road Package: If you mostly drive on the highway, skip this package. The MT tires are louder and will drop your range by about 10-15 miles. Only get it if you're actually hitting the trails.
- Download the myGMC App: Check for Tesla Supercharger compatibility in your area. GM now has access to much of the Tesla network, which makes road-tripping this giant significantly less stressful.
