2027 GMC Sierra EV Performance, Specs, Configurations – The 2027 GMC Sierra EV gets a dramatic redesign that doesn’t just follow the trends—it sets them. Built on GM’s next-generation Ultium platform, the Sierra EV breaks from traditional truck styling with a futuristic silhouette, a smoothed-out front end, and integrated aerodynamics designed to maximize efficiency. The front fascia ditches the conventional grille in favor of a closed-off shield-style panel with dynamic lighting elements that animate on startup. Signature C-shaped LED headlamps and a full-width daytime running light bar give it an unmistakable road presence. 2027 GMC Sierra EV Performance
2027 GMC Sierra EV Redesign and Update Plan
Exterior & Interior
Inside the 2027 Sierra EV, GMC transforms the traditional truck cabin into a high-tech command center. Materials now include open-pore wood, laser-etched aluminum, and vegan leather in higher trims, giving the cabin a premium, yet eco-conscious feel. The new floating 17.7-inch OLED touchscreen dominates the dash, paired with an 11-inch digital driver display and a full-color 15-inch head-up display. This triple-screen setup syncs seamlessly, offering vehicle data, navigation, media, and real-time charging stats in one intuitive interface.
The interior layout focuses on space, comfort, and functionality. The flat-floor design—thanks to the battery placement—allows for more rear legroom and clever storage solutions under the rear seats. Heated, ventilated, and massaging front seats come standard in upper trims, while rear passengers benefit from climate controls, USB-C ports, and even reclining seatbacks in the Denali Ultimate model. Ambient lighting with customizable color profiles gives the cabin a futuristic glow, especially during nighttime drives.
Tech doesn’t stop at displays. GMC’s next-gen Super Cruise comes standard on most trims, enabling hands-free driving on over 400,000 miles of compatible roads across North America. The infotainment system supports Google Built-In, wireless Apple CarPlay, and Android Auto. Over-the-air updates ensure software remains current, adding new features as they become available. A premium 18-speaker Bose Performance audio system, voice-activated controls, and configurable digital switches offer the kind of in-cabin experience that elevates the Sierra EV beyond typical truck standards.
GMC has overhauled the proportions to match the demands of a modern EV truck. The wheelbase is longer, the overhangs are shorter, and the hood is flatter to reduce drag. The front “frunk” is deeper and more accessible than ever, providing lockable, weatherproof storage with integrated lighting and power ports. At the rear, the MultiPro Midgate system has been updated to seamlessly fold the rear seats and rear wall, creating an extended bed length without losing cabin protection. The redesigned tailgate retains six-position functionality, but now integrates with a smart lift system that adjusts height for ease of access or load handling.
The update plan also includes new trims and special editions. A new AT4X off-road variant with beefed-up underbody protection, adaptive air suspension, and terrain-specific drive modes joins the lineup. For luxury seekers, a Denali Ultimate trim brings exclusive materials, a panoramic roof, and bespoke styling. Across all trims, the 2027 Sierra EV is now more modular, offering tailored utility without compromising its bold new EV identity.
2027 GMC Sierra EV Specs
Engine & Performance
Underneath its sculpted body, the 2027 GMC Sierra EV is all about power and versatility. The standard dual-motor all-wheel drive setup produces up to 754 horsepower and 785 lb-ft of torque in Max Power Mode—enough to launch the truck from 0 to 60 mph in just 4.5 seconds. That’s supercar acceleration, wrapped in a full-size pickup. For those needing heavy-duty strength, the truck offers a max towing capacity of up to 12,500 pounds, and a payload limit of 1,400 pounds—numbers that compete with or exceed traditional gas-powered rivals.
GMC includes selectable drive modes like Tow/Haul, Off-Road, Normal, Sport, and MyMode, which allows drivers to personalize suspension settings, steering feel, throttle response, and regen braking. The adaptive air suspension can raise the truck by 2 inches for off-road clearance or lower it by 2 inches for easier loading and improved highway aerodynamics. Regen on Demand and One-Pedal Driving are tuned to feel natural, giving drivers flexibility in how they manage energy and control.
The Sierra EV’s performance doesn’t just live in straight-line numbers. GM’s new e4WD system distributes torque with millisecond precision, maximizing grip on all terrains. The AT4X trim features locking front and rear differentials, specialized underbody armor, and 35-inch Goodyear Wrangler Territory tires for serious off-road adventure. Battery cooling improvements and software optimization reduce thermal fade even under full load or steep grades. Whether you’re towing across states or climbing rocky trails, the Sierra EV delivers confident, precise power. 2027 GMC Sierra EV Performance
2027 GMC Sierra EV Fuel Economy
Efficiency is critical in the EV world, and the 2027 Sierra EV delivers with an EPA-estimated range of up to 460 miles on a full charge for the Extended Range battery. The standard battery pack offers up to 330 miles, ideal for most daily needs and moderate hauling. Thanks to its 800-volt electrical architecture, the Sierra EV supports DC fast charging up to 350 kW, adding roughly 100 miles of range in just 12 minutes under optimal conditions.
Home charging options include a standard 11.5 kW onboard charger and an optional 19.2 kW Level 2 charger for faster overnight charging. The truck also features bi-directional charging, enabling it to power tools, homes, or even other EVs via GMC’s Ultium Power Station Pro. GMC includes energy monitoring features accessible via the smartphone app, allowing drivers to schedule charging during off-peak hours and view real-time consumption.
2027 GMC Sierra EV Safety Features
Safety is core to the 2027 GMC Sierra EV’s design, and the suite of features included reflects that commitment. Standard safety includes Forward Collision Alert, Automatic Emergency Braking, Front Pedestrian Braking, Lane Keep Assist with Lane Departure Warning, and Following Distance Indicator. New for 2027 is Intersection Assist, which uses advanced radar and camera systems to detect cross traffic when turning left, actively intervening if a collision is imminent.
Enhanced driver assistance comes via an upgraded Super Cruise system that includes Automatic Lane Change, Trailer Assist, and Smart Lane Positioning. With embedded LiDAR maps, this system can take full control of the vehicle on approved highways—even when towing. A Driver Attention Camera ensures the driver stays alert, and the system will safely pull over and stop the vehicle if attention is lost. Surround Vision, available on most trims, includes 14 camera views including a transparent trailer view and bed-mounted cameras for safer maneuvering.
Passive safety gets an upgrade too. The Sierra EV’s new frame integrates a high-strength central battery protection cage that absorbs and disperses energy during side and frontal impacts. The battery compartment is shielded with boron steel and monitored by thermal sensors to prevent overheating. Additional airbags have been added for rear passengers, and a new cabin acoustic warning system alerts pedestrians at low speeds. This isn’t just a truck that performs—it’s one that protects at every level. 2027 GMC Sierra EV Performance
