Standing as just the second model year of Big Red’s all-electric super SUV, the 2025 Hummer EV SUV features a few notable updates for the latest model year. Now, we’re taking a closer look at 2025 GMC Hummer EV SUV towing capacities in the following GM Authority breakdown.
Before diving in, here’s a quick rundown of the available powertrain configurations. Ultium battery and Ultium Drive motor technologies work together to deliver propulsion. More specifically, a 20-module battery pack is standard equipment across the lineup, while buyers have the option of either a two- or three-motor setup depending on the trim level selected. Output figures range from 570 horsepower in the 2X trim level to 830 horsepower in the 3X.
With that out of the way, here’s the breakdown on 2025 GMC Hummer EV SUV towing capacities.
2025 GMC Hummer EV SUV Towing Capacities
| Model | Battery | Drivetrain | Ultium Drive Two-Motor XRJ | Ultium Drive Three-Motor XRL |
|---|---|---|---|---|
| Max Trailer Weight (lbs / kg) | Max Trailer Weight (lbs / kg) | |||
| 2X | 20-module | 4WD | 10,000 / 4,536 | - |
| 2X with Z6X Extreme Off-Road Package | 20-module | 4WD | 7,500 / 3,402 | - |
| 3X | 20-module | 4WD | - | 7,500 / 3,402 |
| 3X with Z6X Extreme Off-Road Package | 20-module | 4WD | - | 7,500 / 3,402 |
As evidenced above, 2025 Hummer EV SUV towing maxes out at 10,000 pounds in the 20-module battery, two-motor configuration. Meanwhile, units equipped with the Extreme Off-Road Package (RPO code Z6X) – which adds all-terrain items like skid plates and locking differentials – take a significant blow to towing figures, rated at 7,500 pounds.
It’s worth noting that the owner’s manual of the Hummer EV SUV makes special mention of the One-Pedal Driving feature. In fact, the manual points out that while the feature may be useful when pulling a trailer, the brake pedal may sometimes be required to slow down and hold the all-electric supertruck with large loads or steep hills. In addition, trailer brakes are only activated with the brake pedal, but trailer brake lights will be functional during substantial deceleration or when the EV is stopped. It’s recommended to turn off One-Pedal Driving when roads are less than ideal.
Additionally, there are a number of features and technologies General Motors recommends deactivating before pulling a trailer, including:
- Park Assist
- Reverse Automatic Braking
- Rear Cross Traffic Alert
- Rear Cross Traffic Braking
- Lane Change Alert
- Adaptive Cruise Control (unless the vehicle is equipped with trailering functionality)
- Super Cruise (unless the vehicle is equipped with trailering functionality)
As a reminder, the GMC Hummer EV SUV rides on the wide-body version of the GM BT1 platform, while production takes place at the GM Factory Zero plant in Michigan.
