The Sierra EV produces up to 760 horsepower and 785 lb ft of torque in its maximum power mode.
Understanding Sierra EV Battery Options and Range
The 2026 GMC Sierra EV is built on General Motors' Ultium battery platform. This technology represents a core shift in electric vehicle design. It provides the foundation for the truck's impressive capabilities.
You have two main battery options. The Extended Range battery offers an EPA estimated 410 miles. This pack is available on Elevation and AT4 trims. The Max Range battery pushes the boundary further. It delivers a GM estimated 478 miles of range. You will find this pack on the Denali and AT4 models.
These estimates account for real world factors like climate control use and driving style. Your actual range will vary based on conditions. Colder Spokane winters can reduce range temporarily. Using preconditioning via the myGMC app helps maximize range by warming the battery while the truck is still plugged in.
The Ultium platform uses a large format, pouch style cell design. This allows for efficient use of space within the vehicle's frame. The result is a low center of gravity and balanced weight distribution.
Charging Speed and Vehicle Power
Charging an electric truck needs to be fast. The Sierra EV addresses this with 800 volt architecture. This high voltage system supports DC fast charging at rates up to 350 kW.
At a compatible public DC fast charging station, the Sierra EV can add significant range quickly. With the Max Range battery, you gain approximately 100 to 116 miles in about 10 minutes. A longer charging session can bring the battery from a low state to a high state of charge in well under an hour.
For home charging, the Sierra EV includes a dual level charge cord. You can install a GM approved 19.2 kW AC home charging station for the fastest possible home charging.
Mobile Power Source
The available Energy Transfer Pro system provides up to 10.2 kW of exportable power. Use the 240 volt and 120 volt outlets in the bed to power tools, appliances, or your home during an outage.
Performance
The electric drive system delivers instant torque. With 760 horsepower available, the Sierra EV offers acceleration that outperforms many traditional trucks. The standard horsepower rating is 605.
Sierra EV Trim Highlights and Battery Availability
Each Sierra EV trim level offers a distinct combination of battery options and features. Your choice depends on your required range, budget, and desired technology.
