2025 Hummer EV: Updates to Motors, Magnets, and Inverters?

While researching the new specs for the 2025 GMC Sierra, I came across some interesting comments. Kyle from Out of Spec Reviews mentioned that there are some major upgrades to the new Sierra EV that haven’t been widely discussed. These include improved motors, magnets, inverters, and enhanced aerodynamics, all contributing to better coast down and efficiency, ultimately boosting range.

Does anyone know if these updates are also being applied to the newer Hummer models?

I haven't heard anything yet, but I know that the new Silverado and Sierra EVs are getting good numbers! It would be great if they could apply those improvements to the 2025 Hummer EVs.

I came across something interesting last night while checking out the 2024/2025 Hummer EV 2X that might further confirm changes in the 2025 model.

Here's a window sticker of a 2024 Hummer EV SUV 2x that is showing a 303 mile range.



Here's a window sticker of a 2025 Hummer EV SUV 2x with the same specs that is showing a 315 mile range.

Interesting. You would think that with increased range, the fuel savings and annual costs would be lower.
