The best trucks don’t ask you to choose between capability and comfort. The 2026 GMC Sierra EV carries that energy into the electric era. Powerful, thoughtfully engineered, and packed with useful technology, it’s an electric pickup that feels every bit like a GMC. For drivers searching for an electric truck in Barrington, IL, the Sierra EV is well worth a closer look.
Three Distinct Ways to Experience the Sierra EV
The Sierra EV lineup offers three trims, each with its own personality. The Elevation is the starting point, but it hardly feels entry-level. Standard equipment includes a 16.8-inch Premium GMC Infotainment System with Google built-in, a power-opening eTrunk with 11 cu. ft. of storage, heated front seats, a heated steering wheel, and a 10-way power driver’s seat with lumbar support. Available upgrades include the Extended Range Battery Pack with an EPA-estimated range of up to 410 miles, the MultiPro MidGate®, and available Super Cruise® hands-free driver assistance technology.
The AT4 takes a more adventurous approach. Standard 35-inch all-terrain tires, two additional inches of ground clearance, Four-Wheel Steer with CrabWalk®, Super Cruise®, and a Head-Up Display make it well suited for drivers who regularly venture beyond the pavement. It can also be equipped with the available Max Range Battery Pack offering a GM-estimated range of up to 478 miles. At the top of the lineup sits the Denali, blending premium craftsmanship with exceptional capability. Distinctive 22-inch wheels, refined interior appointments, and standard Super Cruise® are complemented by available features including the Max Range Battery Pack, Energy Transfer Pro with up to 10.2 kW of off-board power, Air Ride Adaptive Suspension, and Four-Wheel Steer with CrabWalk®. If you’re comparing GMC Sierra EV trim levels, each model offers a unique balance of luxury, capability, and performance.
Range That Encourages Bigger Adventures
One of the Sierra EV’s greatest strengths is how confidently it handles long distances. The available Extended Range Battery Pack allows the Elevation to travel up to an EPA-estimated 410 miles on a full charge. Choose the available Max Range Battery Pack on the AT4 or Denali, and that figure climbs to a GM-estimated 478 miles. When it’s time to recharge, available 800-volt DC Fast Charging can add approximately 116 miles of range in about 10 minutes, making road trips and busy workdays far easier to manage. The in-vehicle Energy App also helps owners schedule charging sessions and prepare the battery before departure, making day-to-day ownership refreshingly straightforward.
Capability That Lives Up to the GMC Name
Electric power has transformed what a pickup can do, but the Sierra EV remains unmistakably a GMC truck. Its dual-motor Performance Torque Vectoring e4WD system delivers confident traction while producing up to 760 hp and 785 lbs. ft. of torque in Max Power mode, depending on trim and battery configuration. Properly equipped, the Elevation with the Extended Range Battery Pack can tow up to 12,500 lbs., while the AT4 is rated for up to 12,300 lbs. The Denali Extended Range also offers a maximum towing capacity of 12,500 lbs.
Available Four-Wheel Steer with CrabWalk® improves maneuverability in surprisingly practical ways, while the available MultiPro MidGate® extends maximum cargo length to a class-leading 10 feet, 10 inches when paired with the folded rear seats and removable rear glass. If you’re shopping for GMC trucks in Barrington, IL, the Sierra EV proves that electric capability can be every bit as useful as traditional power.
Technology Designed Around the Drive
The Sierra EV’s interior feels modern without becoming overwhelming. A 16.8-inch infotainment display anchors the cabin, providing intuitive access to navigation, entertainment, and vehicle settings through Google built-in. AT4 and Denali models also feature a 14-inch Head-Up Display, while up to 14 available camera views simplify towing, parking, and maneuvering in tight spaces.
Available OnStar® services add additional convenience with Automatic Crash Response and remote vehicle commands, while more than 16 standard driver-assistance features, including Intersection Automatic Emergency Braking and Side Bicyclist Alert—help make every journey more confident.
