2027 GMC Sierra EV Redesign, Specs, Interior – The 2027 GMC Sierra EV arrives as a flagship representation of General Motors’ commitment to an all-electric future, built on the revolutionary Ultium platform. This year’s Sierra EV is more than a carryover—it’s a full evolution from the 2024 debut model, featuring refined aerodynamics, new structural materials, and a more efficient battery integration system.
Designers reworked the underbody to enhance airflow, added structural reinforcements around the battery cradle, and introduced next-gen Ultium Shield plating for improved thermal management and protection. The result is a stronger, quieter, and longer-lasting electric truck. 2027 GMC Sierra EV Redesign

Exterior & Interior
The 2027 Sierra EV commands attention with its futuristic yet unmistakably GMC design language. Its commanding stance is enhanced by 24-inch turbine-style wheels with integrated cooling fins and low rolling resistance tires. Retractable flush door handles, power-folding side steps, and a full-length light bar in the tailgate are standard across trims. Exterior colors are bold and contemporary, including Glacier Titanium, Obsidian Amethyst, and Voltaic Red, each paired with contrast satin black or chrome trim depending on configuration.
In back, the MultiPro Tailgate is further enhanced with a new auto-leveling suspension calibration and digital keypad system that allows remote opening and preset tailgate modes for loading, working, or relaxing. The power tonneau cover is now solar-enhanced to help trickle charge auxiliary systems. Around the vehicle, 360-degree lighting with programmable scenes adds utility for campsite setups, work zones, or ambient styling. Combined with wider door apertures and a panoramic glass roof, the Sierra EV presents both muscle and modernism in a single visual narrative.
Inside, the 2027 Sierra EV reaches a new echelon of interior design for GMC. The cabin is dominated by a 17-inch OLED central touchscreen with crystal-clear graphics and zero-lag response. It’s flanked by an 11-inch digital driver display and a 14-inch augmented HUD system that overlays navigation, range, and safety alerts directly on the windshield. Premium materials include perforated vegan leather, real ash wood, and aluminum accents—all sustainably sourced. Cabin insulation has been enhanced using triple-layer soundproofing and laminated acoustic glass, creating a near-silent ride experience.
The 2027 model brings a newly revised front lighting signature with laser-cut C-clamp LED projectors that extend into the bodylines, giving the Sierra EV a distinctive and futuristic stance. Designers streamlined the grille-less fascia, replacing it with a sealed lighting panel that dynamically adjusts brightness and displays charging status. Improved active shutter vents around the front wheel arches and lower bumper guide airflow away from turbulent zones, reducing drag. Revised proportions also slightly lower the roofline and push out the wheel arches to provide a wider, planted appearance.
Inside the bed, new integrated power ports and the MultiPro MidGate 2.0 system add unmatched practicality. A re-engineered frunk (front trunk) now features a washable, drainable compartment with power outlets, making it ideal for tools or tailgates. All four corners of the chassis benefit from structural revisions to improve suspension geometry, while the next-generation SuperTruck Tuning Protocol (STTP) enhances ride behavior across varying loads. Everything in the 2027 Sierra EV redesign serves to combine rugged utility with premium sophistication in a zero-emissions framework.
2027 GMC Sierra EV Specs
Engine & Performance
The 2027 Sierra EV runs on GM’s latest dual- or tri-motor Ultium Drive configurations, tuned for maximum torque, efficiency, and towing capability. The base Elevation and SLT trims utilize a dual-motor setup producing 580 horsepower and 615 lb-ft of torque, while the Denali Edition 1 and AT4X get the tri-motor layout generating up to 770 horsepower and an astonishing 800 lb-ft of torque. All trims come standard with e4WD (electric four-wheel drive), enabling real-time torque vectoring and enhanced off-road traction.
Acceleration is staggering for a full-size pickup, with the Denali Edition 1 sprinting from 0 to 60 mph in just under 4.3 seconds. Performance-tuned air suspension with adaptive ride control provides the flexibility to raise or lower the vehicle up to 4 inches depending on drive mode, from highway comfort to trail-ready stance. Standard rear-wheel steering gives this massive truck the turning radius of a midsize SUV, improving both urban maneuverability and trail handling. The new Sierra EV also features One-Pedal Off-Road Mode, enabling tight control over steep or rocky inclines.
Range and charging capability are class-leading. A 212-kWh Ultium battery provides up to 470 miles of range in optimal conditions, with rapid 350 kW DC fast-charging support giving it 100 miles of range in just 12 minutes. Home charging options include an 80A Level 2 charging unit and bi-directional charging capability for vehicle-to-home energy support. For towing, the Sierra EV is rated up to 10,000 lbs on most trims, while a specialized MaxTow package pushes this up to 14,500 lbs, all managed through GMC’s Smart Tow command interface. 2027 GMC Sierra EV Redesign
2027 GMC Sierra EV Fuel Economy
Although electric trucks don’t rely on traditional fuel economy metrics, the Sierra EV demonstrates segment-leading energy efficiency. The tri-motor configuration averages 2.2 miles per kWh, while the dual-motor variants push 2.6 miles per kWh under moderate load. Intelligent energy recuperation systems, including regenerative braking with customizable levels and solar auxiliary charging from the tonneau cover, further extend range during real-world usage. These enhancements are part of GMC’s Zero Waste Energy Drive initiative, making the Sierra EV not only powerful but conscious of energy stewardship.
2027 GMC Sierra EV Safety Features
Safety in the 2027 GMC Sierra EV is deeply integrated, leveraging an advanced sensor suite and AI-powered software to anticipate, react, and intervene when needed. Standard on all models is the new GMC IntelliSense 360 package, combining LiDAR, radar, high-res cameras, and ultrasonic sensors into a cohesive system. New features for 2027 include Predictive Impact Avoidance, Exit-Side Occupant Alert, and AI-assisted Lane Merge Advisor, which calculates real-time merging opportunities on highways and urban streets.
Super Cruise 4.0 comes standard on the Denali Edition 1 and available across the range. This hands-free driver assistance system now supports up to 500,000 miles of mapped roads in North America, with capabilities like auto-lane change, freeway-to-freeway transfer, and smart convoy mode. A driver-facing infrared monitor ensures driver attention is always tracked. Enhanced Surround Vision now features towing overlays, off-road trajectory guidance, and blind zone trailer coverage, greatly increasing spatial awareness in tight spots or rugged terrain.
Passive safety is equally impressive. The Sierra EV includes a 10-airbag array, reinforced battery cage with deformation crumple zones, and emergency battery shutoff system in the event of a collision. Advanced thermal monitoring systems constantly scan the battery system for anomalies, reducing fire risk. Rollover mitigation, trailer sway control, and electronic traction management round out a suite that not only protects passengers but also maintains control even in the most adverse conditions. GMC clearly prioritized making the Sierra EV not just capable, but reliably safe in every scenario.
2027 GMC Sierra EV Release Date & Price
Pricing for the 2027 Sierra EV begins at around $72,900 for the base Elevation model. The SLT trim starts near $78,500, while the off-road-oriented AT4X breaks into the $85,000+ range. The Denali Edition 1, equipped with every luxury and performance feature GMC offers, tops out around $99,500 fully loaded.
