All 3X Hummers with the 24 Module pack get the increased power. They have been marketing the Carbon Fiber Edition because it's a 3X standard and lighter wheels means it can get to the estimated 2.8 Second 0-60 easier.

 

Thank you, was wondering myself. This is an actual improvement, unlike king crab.

 

I just read the fine print on the GMC HEV truck build & buy page and it looks like all 3x models with the 24-module battery will do 2.8 sec 0-60 using WTF.

I like the carbon wheel option but do not care for the amber interior.

 

Amber is yellow.

 

Oops, I was wrong. GMC describes the color as Ember. For some strange reason, GMC seems to be following Jeep and Ford Bronco halo vehicle color highlights even though the the majority of Jeep and Bronco Raptor customers hate the bright red accent. I’m a Jeep 392 owner with the dark seats. I’m also not surprised that Jeep withdrew the red accent based a strong customer feedback.

 

the real question is whether there was an actual hardware or just a software upgrade to unlock the power.

 

I seem to recall reading that the 2026 electric motors were upgraded over previous years. Other than that, it seems like the rest of the improvements are software related.

I'll add that i believe the upgrades to the 2026 are much more significant than GM portrayed.
1) huge increase in towing capacity for 3x models
2) huge HP rating for 3x max range models
3) a massive UI update in terms of both performance and integration with Google services

I wonder whether GM downplayed the enormity of the changes in order to protect dealers sitting on 1000s of unsold 2024 and 2025 models.

where did you see towing capacity increase?

 

The 2026 GMC Hummer EV pickup has different towing capacities depending on the trim level, with the 2X trim towing up to 12,100 pounds and the 3X trim towing up to 10,600 pounds. The towing capacity for the Hummer EV SUV is different, with the 2X towing up to 12,000 lbs and the 3X towing up to 8,500 lbs.

 

I just found it but it only applies to the street Hummer not the off road, which also is currently showing as not available on gmc website.
