Before driving in, here’s a review of the available powertrain configurations. Ultium battery and Ultium Drive motor technologies work together to power all four wheels. More specifically, a 20-module battery pack is standard 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 and Edition 1 variants.
With that settled, here’s the breakdown on 2024 GMC Hummer EV SUV towing capacities:
2024 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) | |||
| 2 | 20-module | 4WD | 10,000 / 4,536 | - |
| 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 |
| Edition 1 | 20-module | 4WD | - | 7,500 / 3,402 |
As demonstrated above, the maximum a 2024 Hummer EV SUV is rated to pull is 10,000 pounds in the 20-module battery, two-motor configuration. Meanwhile, models equipped with the Extreme Off-Road Package (RPO code Z6X) – which features 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 sometime 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.
As a reminder, the GMC Hummer EV SUV rides on the wide-body variant of the GM BT1 platform, while production takes place at the GM Factory Zero plant in Michigan.
