The 2025 GMC Sierra EV debuts the second model year of Big Red’s all-electric pickup model with several significant changes and updates from the 2024 edition. Now, GM Authority is putting the spotlight on the 2025 GMC Sierra EV towing capacity.
Like other EVs, the 2025 GMC Sierra EV can put the considerable power of its electric motors to work for towing. While this can cut significantly into its range per charge, the electric pickup shares several towing advantages with other electric vehicles. These include a low center of gravity thanks to its battery pack, instant torque, and regenerative braking.
Looking first at the propulsion system enabling the towing, the 2025 GMC Sierra EV offers two battery configurations. These include the approximately 170 kWh 20-module pack (RPO code ETI) of the Extended Range variant, which develops 645 horsepower and 785 pound-feet of torque. The other setup is the roughly 204 kWh 24-module battery pack (RPO code ETN) for the Max Range configuration, rated at 760 horsepower and 785 pound-feet of torque.
The Extended Range setup with its 20-module battery offers the highest towing capacity at 10,500 pounds maximum. The Max Range is a close second at 10,000 pounds capacity. Neither truck requires additional equipment to provide basic towing, being set up for that purpose at the factory.
With these preliminaries looked at, you can check out the table below for a summary of 2025 Sierra EV towing:
2025 GMC Sierra EV Towing Capacities
Model Battery Drivetrain Drive Two-Motor XRJ Max Trailer Weight (lbs / kg) Denali Extended Range 20-module 4WD 10,500 / 4,763 Denali Max Range 24-module 4WD 10,000 / 4,536
GM offers a range of useful information for 2025 GMC Sierra EV towing, though the user manual confusingly refers to a 7,000-pound maximum towing capacity that does not correspond to the actual capacity. The Sierra EV should not be used for towing during the first 500 miles it is driven, a “break-in period” that avoids damage to the vehicle.
Furthermore, the first 500 miles of towing should be carried out at speeds below 50 miles per hour, without full-throttle starts during this period. Drive mode (D) should be used for towing, or Tow/Haul for loads closer to maximum. One-Pedal Driving is recommended for efficient deceleration while towing, though heavy loads or steep hills or mountains may require the use of the brake pedal.
GM suggests disabling certain Advanced Driver Assistance System (ADAS) features while towing, though the vehicle may switch some of these off automatically if it detects a trailer. The ADAS features include the following, if present:
- Park Assist
- Automatic Parking Assist
- Reverse Automatic Braking
- Rear Cross Traffic Alert
- Rear Cross Traffic Braking
- Lane Change Alert
- Adaptive Cruise Control
- Super Cruise, unless equipped with trailering functionality
The Automatic Emergency Braking (AEB) and Front
Pedestrian Braking (FPB) should be set to “Alert.” In addition to the manual’s recommendations, you can also check the Trailering Information Label for more info.
As a reminder, the 2025 GMC Sierra EV is motivated by GM drive motor and GM battery technology. The pickup continues to ride on the GM BT1 platform. Production takes place at the GM Factory Zero plant in Michigan with the GM Lake Orion plant in Michigan likely to start production at a future date as well.
