Before we begin, here’s an overview of the available powertrain configurations. Ultium battery and Ultium Drive motor technologies work together to power all four wheels. More specifically, either a 20-module or 24-module battery pack is available, along with either a two- or three-motor setup. Output figures range from 570 horsepower in the 2 and 2X trim levels to 830 horsepower in the 3X – and even 1,000 horsepower with the aforementioned 24-module battery.
With all that covered, here’s the breakdown on 2024 GMC Hummer EV Pickup towing capacities:
2024 GMC Hummer EV Pickup 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 | 12,000 / 5,443 | - |
| 2X | 20-module | 4WD | 12,000 / 5,443 | - |
| 2X with Z6X Extreme Off-Road Package | 20-module | 4WD | 7,500 / 3,402 | - |
| 3X | 20-module | 4WD | - | 8,500 / 3,856 |
| 3X | 24-module | 4WD | - | 8,500 / 3,856 |
| 3X with Z6X Extreme Off-Road Package | 20-module | 4WD | - | 7,500 / 3,402 |
| 3X with Z6X Extreme Off-Road Package | 24-module | 4WD | - | 7,500 / 3,402 |
As evidenced above, the maximum a 2024 Hummer EV Pickup is rated to pull is 12,000 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 drastic blow to towing figures, rated at 7,500 pounds.
It’s worth noting that the owner’s manual of the Hummer EV Pickup 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.
As a reminder, the GMC Hummer EV Pickup rides on the wide-body variant of the GM BT1 platform, while production takes place at the GM Factory Zero plant in Michigan.
