2027 GMC Sierra EV Configurations, Specs, Engine – The 2027 GMC Sierra EV enters the market with a commanding redesign that reflects both strength and intelligence. While the silhouette maintains its rugged DNA, every angle and surface has been refined for better aerodynamics, cooling, and efficiency.
The grille is now fully enclosed, finished in gloss black or signature lighting panels depending on trim. The LED lighting system includes animated sequences for welcome and departure, plus more efficient projector beams. The hood line is slightly lowered for forward visibility, while body panels feature contoured sculpting that improves drag without sacrificing the truck’s aggressive stance. 2027 GMC Sierra EV Configurations

Exterior & Interior
Inside, the 2027 Sierra EV is a dramatic leap forward. The dashboard is dominated by a 16.8-inch vertical center display powered by GM’s next-gen Ultifi software, flanked by an 11-inch reconfigurable digital instrument cluster. The interior is bathed in high-quality materials, including real wood, aluminum accents, and soft-touch surfaces. Sierra EV Denali models offer leather-wrapped dash trim, massaging front seats, and a panoramic fixed-glass roof with UV protection. Rear-seat passengers get best-in-class legroom and a flat floor layout that improves comfort and utility.
New tech features make the interior feel like a digital lounge on wheels. A 14-speaker Bose Performance Series audio system is available, and the truck offers Google Built-In with seamless voice commands and integrated navigation. Wireless Apple CarPlay and Android Auto come standard, and the center console now houses a wireless charging pad that can accommodate two devices simultaneously. With multiple USB-C ports, 120V outlets, and customizable ambient lighting, the Sierra EV’s cabin is tailored to modern life, whether you’re towing, camping, or commuting.
GMC’s design team didn’t stop at aesthetics. The bed has been reengineered to include a power-operated midgate, similar to the Hummer EV, which allows for cargo flexibility extending up to 10 feet. There’s a new front trunk (frunk) with integrated cargo bins, outlets, and tie-downs, boosting practicality. The MultiPro tailgate remains but now includes an optional power-actuated system with hands-free operation. Smart updates, such as improved weather sealing and a more modular approach to bed accessories, give the 2027 Sierra EV a functional edge over traditional pickups and competitors alike.
