2027 GMC Hummer EV SUV Redesign and Update Plan
Exterior & Interior
The Hummer EV SUV continues to turn heads with its brawny presence, but it now looks even more polished. GMC refines its exterior lines for better airflow, and adds active underbody flaps to aid off-road articulation. New wheel designs up to 24 inches in diameter come paired with off-road-rated Goodyear or Michelin all-terrain tires. A redesigned rear tailgate integrates a power-actuated split function and a sleek full-width LED signature, while roof rails are now modular and retractable to reduce drag when not in use. The glass roof panels are electrochromic and tint-adjustable, offering control over ambient light and cabin temperature.
Inside, the 2027 Hummer EV SUV steps deeper into luxury territory. The cabin now features a dual-layer dashboard with a floating 15.6-inch infotainment screen and an upgraded 12.3-inch driver display. Finishes include laser-etched metal inlays, perforated semi-aniline leather seats, and contrast stitching that reflects the vehicle’s exterior color. A new “Lunar Terrain” interior package introduces moon-surface-inspired textures on the floor mats, dashboard, and door inserts. Seating comfort is boosted with 18-way power adjustments, ventilated massaging front seats, and heated rear seats as standard across most trims.
In terms of structural updates, the 2027 model rides on the enhanced Ultium Platform 2.0, which incorporates higher-density battery cells and a more compact power electronics module. These changes result in better packaging, lower curb weight, and improved overall efficiency. GMC has also made improvements to the ride quality by tweaking the adaptive air suspension, enabling faster response in real-time off-road scenarios. The updated SUV also benefits from new OTA-enabled software layers, allowing more customizable drive modes and better integration with future software upgrades and third-party services.

Engine & Performance
Under the skin, the 2027 Hummer EV SUV steps up its game with a new tri-motor Ultium Drive configuration on the Edition Omega and Edition 3X trims. The updated motors push output up to 1,100 horsepower and a staggering 11,800 lb-ft of torque (wheel torque), making it one of the most powerful SUVs on sale. This setup delivers a 0–60 mph time of just 3.3 seconds, aided by an improved “Watts to Freedom 2.0” launch control system that adapts based on tire wear and traction conditions. Rear-axle torque vectoring also makes its debut, giving the SUV more agility despite its size.
Lower trims, like the Hummer EV2 and EV2X, retain dual-motor configurations producing around 625–800 horsepower, with a standard electronic locking differential and a single-speed gear ratio optimized for crawling and towing. GM’s updated e4WD software further refines traction management, while the next-gen CrabWalk system now includes diagonal trail assist and tighter turning calibration for city use. Off-road performance is also enhanced with a deeper fording depth of 36 inches, increased wheel articulation, and a factory-integrated winch option that can be operated via the central display or GMC mobile app.
2027 GMC Hummer EV SUV Fuel Economy
The updated Ultium battery in the 2027 Hummer EV SUV is more energy-dense, offering up to 370 miles of range on the tri-motor configuration and up to 430 miles on the dual-motor EV2X trim with extended-range battery. Fast charging has also improved thanks to the 350 kW DC capability, enabling 100 miles of range in just 10 minutes. For those using home chargers, a new 19.2 kW onboard AC charger is included, shortening overnight charging times significantly and supporting bidirectional vehicle-to-home energy transfer. 2027 GMC Hummer EV SUV Specs
2027 GMC Hummer EV SUV Safety Features
Safety is as robust as the rest of the SUV. The 2027 Hummer EV SUV comes equipped with Super Cruise Ultra, GM’s most advanced version of hands-free driving. It adds lane change on command, lane centering in complex environments, and auto-maneuvering in traffic jams. Enhanced LiDAR mapping and a wider network of mapped roads make long trips easier than ever. Active safety includes forward collision alert with pedestrian and cyclist detection, intelligent automatic emergency braking, blind-zone steering assist, and adaptive LED lighting that adjusts beam spread based on road curvature and weather.
New for 2027 is a 360° Terrain Vision AI system with 12 underbody and exterior cameras that display real-time trail data, wheel articulation, and potential obstacle paths. Occupant safety is bolstered by an eight-airbag setup, with new additions including rear-seat side airbags and a far-side center airbag to reduce head injuries during side impacts. GMC also debuts a post-collision automatic hazard and communication protocol, which contacts emergency services, activates the horn and hazard lights, and unlocks doors upon impact.
