Trim and Powertrain

There are three core trims for the 2026 Sierra EV: Elevation, Denali, and AT4. The Elevation is available in the Standard Range and Extended Range versions; those two are also offered for the Denali, along with Max Range. The AT4 comes in the Extended and Max Ranges. All Sierra EVs are all-wheel drive and have a five-passenger crew cab configuration with a 70.59-inch cargo bed. The cargo capacity for most trims is 2,250 pounds (1,950 pounds for the AT4). The Elevation and Denali can tow up to 12,500 pounds, while the AT4 can take on an iota less (12,300 lb.).

The Standard Range editions have dual electric motors producing 605 horsepower and 605 lb.-ft. of torque. The GM-estimated range is 283 miles, and Level 3/DC fast charging for these versions is at 475 volts at up to 220 kW. The Extended Range Sierra EV offers 390 to 410 miles of range and make between 625 and 645 horsepower and 765 to 785 lb.-ft. of torque (depending on the core trim). Fast charging increases to 670 volts at up to 300 kW. The Max Range editions produce 725 horsepower and 775 lb.-ft. of torque (AT4) or 760 horsepower and 785 lb.-ft. of torque (Denali). Higher capacity fast charging is at 800 volts at up to 300 kW. The GM-estimated maximum range for these configurations is 478 miles. At peak charging capacity, the Max Range editions can add 100 miles of range in about 10 minutes. An optional North American Charging Standard (NACS) adapter provides access to Tesla’s charging network.
