New 2027 GMC Sierra EV Specs, Redesign, Configurations – The New 2027 GMC Sierra EV represents a bold step forward for the brand, blending traditional truck toughness with futuristic electric capability. GMC has redesigned the Sierra EV from the ground up, using General Motors’ Ultium platform as its backbone. This dedicated EV architecture not only provides scalability but also ensures better weight distribution, improved handling, and more space for interior and cargo. The update plan focuses on bringing more trims, improved range, and greater towing capacity compared to the initial Sierra EV releases. New 2027 GMC Sierra EV Specs
New 2027 GMC Sierra EV Redesign and Update Plan
Exterior & Interior
The exterior of the 2027 GMC Sierra EV strikes a balance between rugged utility and futuristic style. Up front, a bold LED signature lighting design outlines the sealed grille, giving the Sierra EV an instantly recognizable face. The body features sculpted panels for a dynamic look while maintaining durability with high-strength aluminum and steel construction. Functional features like an available panoramic glass roof, retractable side steps, and large aerodynamic wheels not only improve efficiency but also add a premium touch.
At the rear, GMC integrates an advanced version of the MultiPro tailgate, now offering additional modular storage solutions and power outlets for job-site or recreational use. A power-operated tonneau cover, enhanced bed lighting, and a 240-volt onboard power system transform the Sierra EV into a mobile workstation. Aerodynamic enhancements, such as flush door handles and underbody shielding, allow the truck to achieve better range without compromising its bold pickup design.
Inside, the Sierra EV feels more like a luxury SUV than a traditional truck. The cabin is fitted with premium materials, including available perforated leather, open-pore wood trims, and aluminum accents. A massive 17-inch center touchscreen anchors the dashboard, complemented by a digital instrument cluster and a head-up display. The interior design emphasizes spaciousness with a flat floor layout, thanks to the Ultium platform. Practical storage compartments, fold-flat rear seats, and a lockable front trunk (frunk) expand the truck’s versatility for both work and family use.
Visually, the 2027 Sierra EV receives sharper lines, sleeker aerodynamics, and a commanding stance. Designers have integrated functional updates such as an adaptive air suspension system, an upgraded MultiPro tailgate, and a refreshed front-end design with a more aggressive closed grille that doubles as a charging port. These enhancements align with GMC’s goal of making the Sierra EV both highly capable and distinctively premium.
Another part of the update plan is expanding configurations. GMC intends to offer the Sierra EV in multiple trims, from work-ready models designed for contractors to luxury-focused Denali trims and performance-oriented versions that rival off-road competitors. With these changes, the 2027 Sierra EV isn’t just an electric truck—it’s GMC’s vision of how pickup versatility should evolve in an electric era. New 2027 GMC Sierra EV Specs

Engine & Performance
The 2027 GMC Sierra EV is built on Ultium battery technology, delivering impressive power and versatility. Base models are expected to come with dual-motor all-wheel drive, producing around 560 horsepower and 615 lb-ft of torque. Higher trims like the Denali Edition 1 could push performance to over 750 horsepower and 785 lb-ft of torque, making the Sierra EV capable of sprinting from 0–60 mph in less than 4.5 seconds—a remarkable feat for a full-size truck.
Towing and payload capacities are also a highlight. The 2027 Sierra EV is projected to tow up to 12,000 pounds in its higher trims, with future versions offering even greater capability. Payload capacity is estimated at around 1,800 pounds, making it practical for both heavy-duty work and lifestyle needs. The advanced suspension system, with adaptive air dampers, enhances both ride comfort and handling precision.
Performance off the pavement is just as impressive. Select trims will feature GMC’s CrabWalk technology, borrowed from the Hummer EV, allowing diagonal movement for navigating tight spaces. Four-wheel steering improves maneuverability, making parking and trail driving easier. With multiple drive modes—including Tow/Haul, Off-Road, and Sport—the Sierra EV adapts to different terrains and demands while delivering consistent power and smooth acceleration.
New 2027 GMC Sierra EV Fuel Economy
Range is one of the Sierra EV’s strongest selling points. With GM’s next-generation Ultium batteries, the 2027 Sierra EV is projected to deliver up to 450 miles on a single charge, depending on trim and configuration. Standard versions may offer closer to 350 miles, still more than enough for daily driving and light-duty work. Fast-charging capability allows the Sierra EV to recover up to 100 miles of range in just 12 minutes when using a 350-kW DC fast charger.
Charging flexibility is also key. Owners can charge at home using Level 2 charging systems, and GMC provides vehicle-to-home (V2H) power functionality, enabling the Sierra EV to act as a backup generator during outages. The truck’s bi-directional charging capability also supports vehicle-to-vehicle charging, making it a valuable asset on job sites or camping trips.
New 2027 GMC Sierra EV Safety Features
The 2027 Sierra EV brings state-of-the-art safety systems to ensure peace of mind for drivers and passengers alike. GMC includes its latest driver-assistance suite as standard, offering forward collision alert, automatic emergency braking, lane-keeping assist, and blind-spot monitoring. Adaptive cruise control with stop-and-go functionality, enhanced by radar and camera-based systems, makes highway driving both safer and more relaxing.
One of the most advanced features available on the Sierra EV is Super Cruise, GMC’s semi-autonomous hands-free driving system. In its 2027 iteration, Super Cruise supports more mapped miles of roads across North America and adds automated lane change capabilities. This allows Sierra EV owners to enjoy hands-free driving on highways, a huge advantage for long-distance haulers and commuters.
Additional technology includes a 360-degree HD camera system, transparent trailer view, and advanced trailer sway control, all of which make towing easier and safer. Inside, passengers benefit from advanced occupant protection, including knee and side-curtain airbags, and a reinforced safety cell built around the Ultium battery pack. Over-the-air software updates ensure that the Sierra EV’s safety and tech features remain cutting-edge throughout its lifecycle. New 2027 GMC Sierra EV Specs
New 2027 GMC Sierra EV Release Date & Price
Pricing for the New 2027 GMC Sierra EV is expected to start around $65,000 for the base trim, with well-equipped models ranging between $75,000 and $95,000.
