Hello everyone, I am a former Tesla Cybertruck who recently sold the CT and bought a Hummer EV SUV. I took this beast on a 900 mile road trip to see how it did with charging and how Super Cruise did vs my experience with FSD.

Overall charging was great at Tesla SuperChargers besides the speeds capping out at 150kw. The one EVgo charging stop that we did was a disaster And Super Cruise did great on the trip. FSD is better but SC was good enough for me.

I have a YouTube channel if you’re interested please watch the video below and subscribe as I plan to do off road and overland camping videos.

Thanks

The GMC HUMMER EV carved a new segment as the first and only EV supertruck when it launched. With the new software-enabled King Crab off-road rear-steer mode (available over-the-air to all HUMMER EV owners as a bonus) and faster acceleration (GMC HUMMER EV Carbon Fiber Edition Pickup offers 0-60 mph launches in just 2.8 seconds) – the 2026 edition is now more capable and more advanced than ever.

Unrivaled off-road capability

Fresh for 2026 is the launch of King Crab, an all-new advanced rear-steer mode experience. King Crab takes the HUMMER EV’s standard four-wheel steer agility to the next level to further improve maneuverability in off-road settings. The feature is standard across the 2X and 3X Pickup and SUV trims.

When King Crab mode is activated, the rear wheels turn significantly faster than the front wheels. That results in more maneuverability when navigating tight spaces off-road, moving around obstacles or rock crawling. No other 4x4 offers this kind of rear wheel agility.

But this new feature isn’t just available on the 2026 model, King Crab is also expected to launch to all 2022 through 2025 HUMMER EV Pickup and SUV owners through an OTA update available later this year. King Crab fulfills a promise set at the HUMMER EV Pickup’s original launch to deliver on the famed “Mystery Mode” button where owners could submit their own “epic ideas” to GMC.

New vehicle features like King Crab are made possible through hardware and software all working together with vehicle integration to seamlessly showcase everything an all-electric vehicle can be - with a new feature off-roaders want.

“The refreshed HUMMER EV enhances an already amazing vehicle with new software innovations and forward-thinking design,” said Al Oppenheiser, GMC HUMMER EV chief engineer. “From the start, we aimed to provide HUMMER EV owners over-the-air software updates. All 2026 HUMMER EV owners will have access to our latest software going forward, allowing new features to be introduced throughout the vehicle's lifecycle.”

Carbon Fiber Edition: The quickest HUMMER EV ever

The 2026 model reveals the exclusive HUMMER EV Carbon Fiber Edition Pickup and SUV with only a limited number scheduled for production. Available for the 3X Pickup and SUV, this is the latest limited edition under the HUMMER EV nameplate.

Enabled by the available 24-module battery, the Carbon Fiber Edition Pickup not only looks incredible, but it also takes the title as the quickest HUMMER EV yet – launching from 0-60 mph in a jet-setting 2.8 seconds. This faster-than-ever supertruck was made possible through optimization of software and propulsion calibration, as well as developments in hardware and analysis work.

In addition to stunning acceleration, the Carbon Fiber Edition provides higher contrast colors and a brighter palette.

All Carbon Fiber Edition Pickups and SUVs feature an exclusive Magnus Gray Matte exterior and Velocity Ember interior theme with colors selected to show movement and form. These special edition units will also include the following as standard:

• Unique 22-inch carbon fiber black wheels
• All-Terrain tires
• Carbon fiber inserts in the mirror caps and skid plate
• Black approach shield
• Black emblems
• Black power tonneau cover (Pickup only)
• 22-inch spare carbon fiber black wheel (SUV only)

More innovation

For 2026, the HUMMER EV will offer bidirectional charging capability for both vehicle-to-vehicle & nbsp; and vehicle-to-home. With vehicle-to-vehicle, the 2026 HUMMER EV can transfer power to another compatible EV. And a vehicle-to-home-capable 2026 HUMMER EV can provide power to a home in a blackout when properly equipped.

The 2026 HUMMER EV also comes with enhanced Super Cruise, the industry's first true hands-free advanced driver assistance system. This includes Hands on Lane Change Assist (HOLCA), which allows for seamless transition between non-Super Cruise mapped and Super Cruise-mapped roads. In addition, Super Cruise will now offer a Lane Change for Route feature to automatically change lanes on Super Cruise-mapped roads if the vehicle’s built-in map is being used.

The capability continues with the available 24-module HUMMER EV 3X Pickup delivering 1,160 horsepower and 13,000 lb-ft of torque, which makes it the most powerful truck available in its class.

Also new for 2026: further optimization of the HUMMER EV's damper tuning, resulting in improved overall ride quality.

The 13.4-inch diagonal premium GMC infotainment center includes a customizable split view screen for consistent access to important vehicle data. Google Built-In brings expanded entertainment options to enjoy while charging. Powered by OnStar connectivity, owners will receive intelligent EV routing, voice assistance and access to apps like Chrome, GameSnacks, and Prime Video.

Fresh design

The HUMMER EV Pickup and SUV continues to embody the premium off-road lifestyle with bold on-road styling, every day practicality, and GMC’s signature premium comfort.

New for 2026 are two additional exterior paint colors available – Coastal Dune and Auburn Matte – as well as two new interior themes – Granite Drift and Stealth Eclipse.

Available later this summer

Production of the 2026 HUMMER EV will begin later this year at GM’s Factory ZERO Assembly Center in Detroit and Hamtramck, Michigan, home to GMC’s three all-electric trucks: the GMC HUMMER EV Pickup, HUMMER EV SUV and Sierra EV.

The 2026 HUMMER EV Pickup and SUV will be available at GMC EV dealers later this year. Pricing and GM-estimated range will be announced closer to launch.

I received the update this morning, and it installed without any issues. However, it did seem to take quite a bit longer than the estimated 15 minutes.

One interesting thing I noticed: before the update, I had 135 miles of range, but afterward, it showed 175 miles. Maybe it just needs to recalibrate after some driving time?

Still anxiously waiting for mine.

A few things I believe they could add OTA.
1. Sentry Mode (use existing cameras).
2. Customized horn/lock car sounds (use existing exterior speakers).
3. Potentially more capable Super Cruise to handle city autopilot.
4. More range on the Rear Wheel steering. Make it a parallel parking dream with full range.

Then little things that just make sense with existing hardware.
1. Auto seat memory/One button press seat memory (currently you have to hold 1/2 until the seat returns)
2. Auto up and down windows. Goes for the all windows button. Include the back window too.
3. Full Screen Apple Carplay or video play when watching while charging.
4. Add Netflix/Disney+ to GM Studio and allow them to play in full screen.

I'm sure I can think of more but those come up off the top of my head.

Congrats, @cmac610! You clinched first place in the April 2025 Hummer of the Month contest with a seriously killer photo.

Is it an OTA update? I thought I read somewhere that it’s a new feature on the ‘26 Hummer? Although I’d love to see it as an update for ours!

we will find out soon enough, but rumours i heard were all that its an OTA update to add functionality of some sort...but they are all just rumours.

The claim that Ultium Cells can "make enough cells to build a new electric vehicle nearly every minute" holds for their combined output (37.32 EVs/hour ≈ one every 1.61 minutes, close to "nearly every minute").

However, the claim that "they already produce more cells than Tesla Inc. does in North America" is not supported:

In terms of number: 10,075 vs. 232,912 cells/hour.
In terms of energy: 3,727.75 vs. 6,543 kWh/hour.
In terms of EV production potential: 37.32 vs. 87.25 EVs/hour.

The discrepancy likely arises from the difference in cell sizes and production metrics. Ultium Cells use larger pouch cells (0.37 kWh each), while Tesla uses smaller cylindrical cells (0.021 kWh for 2170, 0.1 kWh for 4680), allowing Tesla to produce more cells in number but with varying energy contributions. The user's statement may reflect a misunderstanding, focusing on cell count rather than energy capacity or EV production potential, where Tesla currently leads.

Given the plants are not at full capacity (Tennessee at 32%, Ohio at 47%), their potential to surpass Tesla exists if they ramp up to full capacity (85 GWh/year vs. Tesla's current 57.25 GWh/year). However, based on current rates as of May 2025, the claim does not hold.

GM is rolling out another OTA update! According to the release notes:

* Improves accuracy of service messages for high voltage charging system
* Reduces drain on 12V Battery.
* Improves performance of charging.
* Improves performance of wireless communication of the Lithium Ion battery status
* Improves performance of cabin heating and windshield defrosting system.

My update showed up on my vehicle this morning. Update completed successfully!
