Every model includes a 16.8-inch diagonal Premium GMC Infotainment System featuring Google built-in and voice-activated controls, allowing seamless smartphone integration and access to navigation and entertainment. Advanced driver assistance is led by Super Cruise, GMC's hands-free driving technology, paired with a generous three-year OnStar One Plan to keep drivers connected and informed. Higher trims such as AT4 and Denali also offer a multicolor head-up display, up to 14 camera views for precise maneuvering, and features like 4-Wheel Steer with CrabWalk, Air Ride Adaptive Suspension, and panoramic fixed glass roof to elevate both capability and comfort.

The advantages of going electric with the 2026 Sierra EV extend beyond its modern powertrain.
