New 2027 GMC Sierra EV Changes, Redesign, Specs – The New 2027 GMC Sierra EV represents a bold evolution in GMC’s legendary truck lineup, combining the rugged character of the Sierra with an entirely electric powertrain built for the future. This next-generation model builds upon the momentum of the first Sierra EV Denali Edition, introducing refined technology, improved range, and a more aerodynamic yet powerful design language. Built on GM’s advanced Ultium platform, the 2027 Sierra EV is designed to deliver exceptional capability, smooth performance, and zero-emission efficiency without compromising on strength or luxury.
In terms of updates, GMC has taken a holistic approach to redesign. The 2027 Sierra EV gets a stronger structural battery chassis, allowing greater rigidity and improved weight distribution. Engineers focused heavily on aerodynamics, optimizing every surface to minimize drag while retaining a muscular stance. The redesigned front fascia eliminates the need for a traditional grille, replaced by a signature illuminated panel that gives the truck a commanding night presence. The lighting animation—both front and rear—has been reprogrammed to deliver an unmistakable visual sequence when locking or unlocking the truck. New 2027 GMC Sierra EV Changes

Exterior & Interior
The exterior of the 2027 GMC Sierra EV makes an immediate impression with its futuristic yet purposeful design. It retains the bold proportions expected of a Sierra while adopting sleeker lines and smoother surfaces for aerodynamic efficiency. The front end is characterized by an illuminated GMC badge embedded in a blacked-out shield panel, flanked by signature C-shaped LED lighting elements that double as daytime running lamps. The sculpted hood and pronounced fenders emphasize the truck’s confidence, while the flush door handles and smoothed corners enhance airflow. Optional 24-inch alloy wheels give the Sierra EV a dominating road presence, complementing its high beltline and extended wheelbase.
Moving toward the rear, the 2027 Sierra EV’s MultiPro Midgate system remains a highlight. This feature allows the rear wall between the bed and cabin to fold, extending the usable cargo length up to 10 feet when the tailgate is deployed. The truck bed itself is lined with durable composite materials and includes multiple power outlets through the Power Station Pro system, capable of delivering up to 10.2 kW of power to tools, appliances, or even another electric vehicle. The new integrated tonneau cover and side storage compartments give the truck unmatched practicality, while sleek LED taillights stretch horizontally, emphasizing the width and modernity of the vehicle’s rear profile.
Inside, the 2027 Sierra EV’s cabin combines modern digital luxury with rugged functionality. The interior design centers around a massive 16.8-inch portrait-oriented infotainment touchscreen powered by GM’s next-gen software interface, paired with an 11-inch digital driver display. High-quality materials such as open-pore wood, brushed aluminum, and vegan leather upholstery define the Denali trim, while ambient lighting adjusts based on driving modes. GMC’s new “Infinity Roof” with electrochromic panels allows adjustable transparency for an open-air feel. Every seat offers heating, cooling, and massage functions, while the acoustic glass and improved cabin insulation deliver one of the quietest rides in the segment.
Beyond cosmetic refinements, the 2027 Sierra EV integrates smarter functionality across its build. It features enhanced software-over-the-air capabilities, allowing GMC to update performance parameters, charging profiles, and driver-assistance systems remotely. Structural integrity has been improved by using more high-strength steel mixed with lightweight aluminum components, helping balance strength and efficiency. The 2027 Sierra EV isn’t just a continuation—it’s a full-scale technological reinvention designed to redefine what a full-size electric pickup can achieve in both performance and practicality.

Engine & Performance
The 2027 GMC Sierra EV is engineered to perform far beyond expectations. Built on the Ultium electric architecture, it features a dual-motor all-wheel-drive setup in the Denali and AT4 trims, producing up to 754 horsepower and 785 lb-ft of torque. This immense power allows the Sierra EV to accelerate from 0 to 60 mph in just 4.2 seconds—astonishing for a full-size pickup. The lower trims, such as the Elevation model, will deliver around 500 horsepower with a single-motor rear-drive option, catering to efficiency-focused buyers who still demand strength and capability.
The Ultium platform’s modular battery system provides versatility and impressive range. The top-tier 200-kWh battery pack offers an estimated 440 miles of range, while the mid-range version targets around 350 miles per charge. Fast-charging capability via an 800-volt system allows the Sierra EV to regain up to 100 miles of range in approximately 10 minutes using DC fast chargers. The advanced energy management system optimizes battery cooling and regeneration during braking, extending overall efficiency and longevity. The Sierra EV also supports bidirectional charging, allowing owners to power their homes for several days during outages—a key feature in GMC’s Power Station Pro technology.
Performance extends beyond straight-line power. The Sierra EV comes equipped with adaptive air suspension, automatically lowering at highway speeds for better aerodynamics and raising for off-road use. GMC’s four-wheel steering system, known as CrabWalk, enables diagonal movement at low speeds, making tight turns or trail navigation effortless. With a towing capacity of up to 10,000 pounds and a payload rating exceeding 1,400 pounds, the Sierra EV easily matches or surpasses traditional combustion models in capability. The precision-tuned regenerative braking system allows one-pedal driving, offering smooth deceleration while replenishing the battery efficiently.
New 2027 GMC Sierra EV Safety Features
Safety remains a core pillar of the 2027 GMC Sierra EV, with an extensive suite of advanced driver-assistance technologies. The truck comes standard with Super Cruise, GM’s hands-free driving system, now upgraded for towing and compatible with over 800,000 miles of mapped highways across North America. The latest version integrates adaptive lane centering, automated lane changing, and real-time navigation adjustments using high-definition maps and GPS data. Super Cruise has been enhanced to communicate directly with the truck’s battery management and braking systems, ensuring seamless energy efficiency even when driving autonomously.
The Sierra EV’s Active Safety Shield integrates radar, cameras, and ultrasonic sensors for complete 360-degree awareness. Key features include Automatic Emergency Braking, Front Pedestrian Detection, Rear Cross Traffic Alert, Blind Zone Steering Assist, and Intersection Collision Avoidance. The Surround Vision system provides a 3D overhead view, while the Transparent Trailer View allows drivers to virtually “see through” their trailer using real-time video stitching technology. For off-road scenarios, the truck’s underbody cameras display terrain conditions to avoid obstacles and improve wheel placement precision.
Inside the cabin, safety is supported by advanced occupant protection systems and smart monitoring technology. The Driver Attention System tracks eye movement and steering input, alerting the driver if fatigue or distraction is detected. In emergencies, the vehicle can automatically slow down and come to a controlled stop. The Sierra EV also debuts Connected Vehicle Safety, allowing the system to communicate with nearby vehicles and infrastructure to warn of hazards ahead. Combined with 10 airbags, rigid body architecture, and adaptive crash detection, the 2027 Sierra EV sets a new benchmark in electric truck safety. New 2027 GMC Sierra EV Changes
