GMC HUMMER EV SUV

2026 GMC HUMMER EV SUV 3X — US (LHD) SPECIFICATION

Electric Powertrain and Drivetrain

The HUMMER EV SUV 3X uses GM's Ultium Drive tri-motor Performance Torque Vectoring e4WD layout — a single front drive unit and a dual-motor rear drive unit — producing a GM-rated 830 horsepower (619 kW) and a maximum 11,500 lb-ft (15,592 Nm) of wheel torque. Note that the 11,500 lb-ft figure is GM's published maximum torque measured at the wheels, not motor shaft torque. Final drive ratios are 13.26:1 front and 10.49:1 rear. Drive reaches the road through a single-speed electric drive unit with an electronic transmission range selector; there is no multi-speed gearbox. GM quotes 0-60 mph in approximately 3.5 seconds using the Watts to Freedom launch mode. A Regen on Demand steering-wheel paddle and a driver mode selector with Tow/Haul are standard.

Battery, Charging and Range

Energy is stored in a 20-module Ultium battery pack. GM does not publish a gross or usable kWh figure for this pack in any consumer, fleet or regulatory document, so no capacity is stated here rather than an estimate being substituted. GM's published estimated range for the 3X is 312 miles (502 km), and the EPA label figures are 58 MPGe city, 46 MPGe highway and 52 MPGe combined. The vehicle carries a 19.2 kW high-voltage onboard AC charging module and a dual-level charge cord, and supports DC fast charging at up to 300 kW. Energy Transfer Pro and vehicle-to-home (V2H) capability are standard, allowing the pack to power external loads. The charge port is mounted at the rear.

Chassis, Steering and Brakes

The 3X rides on Air Ride Adaptive Suspension with adjustable ride height, combined with a real-time damping chassis and Ride and Handling suspension tuning. Electronic four-wheel steering with CrabWalk diagonal-drive functionality at low speed is standard, as is King Crab mode. Braking is by four-wheel antilock discs with FNC-treated rotors, integrated electronic brake apply control, an electric parking brake and StabiliTrak electronic stability control with traction control. Standard ground clearance is 259 mm front and rear, rising in Terrain and Extract modes.

Dimensions and Capacities

Overall length is 5,250 mm (206.7 in) including the rear-mounted spare wheel, on a 3,226 mm (127.0 in) wheelbase.

GM does not publish a curb weight or a Gross Vehicle Weight Rating for this model; the NHTSA vehicle record classifies it only as GVWR Class 3 (10,001-14,000 lb / 4,536-6,350 kg).
