    Introduction

    2022 GMC Hummer EV Turns an Off-Road Legend Into a Green Machine

    The full-electric SUV and pickup truck promise an emissions-free, open-air experience

    Overview

    General Motors unveiled the all-new electric GMC Hummer EV SUV, following up its reveal of a pickup truck last year. These high-tech, off-road-ready models look to reinvent the Hummer brand that was retired a decade ago.

    GMC promises that the new Hummer EV SUV and pickup truck will be both green and off-road-ready, with gratuitous horsepower and torque, and consequently quick acceleration. They are positioned as premium products that showcase numerous innovations.

    By relaunching Hummer as a sub-brand under GMC, it enables the rollout to take advantage of an established dealer network. And limits the number of true General Motors brands to four. The automaker previously announced that it would invest $2.2 billion in its Detroit-Hamtramck factory to make the Hummer EV and other electric trucks, such as the Cruise Origin, an electric self-driving vehicle. Production of the new Hummer EV pickup truck is expected to begin in late 2021 with availability in early 2022. The SUV will go into production in early 2023.

    The first wave of Hummer EV pickup trucks will be called Edition 1, with a starting price of $112,595, including destination charge. These sold out via online preorders within 10 minutes of the unveiling Oct. 20, 2020. GMC would not confirm how many Edition 1 trucks were allocated. A similar preorder process is being used for the SUV.

    The Hummer EV pickup is a modern take on the H2 sport utility truck, a version of the H2 SUV with a small bed. The Hummer EV pickup has a larger capacity than its progenitor, with a clever MultiPro tailgate that folds open to create a step for climbing into the 5-foot bed, as seen on select GMC pickup trucks.

    Overall length is about 18 feet, splitting the difference between the Yukon and the supersized Yukon XL. It rides on a 135.6-inch wheelbase, making the space between the wheel centers longer than on the GMC Yukon XL. The SUV rides on a wheelbase that is about 9 inches shorter, giving it tidier dimensions. The Hummer EVs push the wheels out to the corners, giving them a trail-ready approach and breakover angles that make them capable of crawling over steep obstacles.

    From the front, the design shares a connection to the H2 with its wide, short six-segment grille. From the side, the pickup has more in common with the Rivian R1T—an upcoming rival electric truck in development.

    Bulging fenders and large, squared-off wheel arches declare the Hummers’ off-road intentions. The black bumper and dark, lower front end make the truck look taller and more imposing.

    For both body styles, the standard wheel-tire configuration is 22-inch-diameter wheels wrapped with 35-inch-tall tires. The Extreme Off-Road Package pairs 18-inch-diameter wheels with 35-inch tall Goodyear Wrangler Territory MT tires. The truck is designed to fit massive 37-inch-tall tires, if owners wish to upgrade. Drivers who wish to deflate the tires to increase traction off road can use the inflation assist system to input a target tire pressure in the gauge cluster. Tire pressure must be released manually, but the Hummer EV will give an audible signal when the desired pressure is reached.

    The Infinity Roof opens up the top with a combination of removable, transparent panels, akin to the Ford Bronco and Jeep Wrangler, with a protective roll cage. The panels can store under the hood in the “frunk”—the space where the gas-powered engine would normally be found.

    There is a rear power window on both body styles, and a powered tonneau cover for the truck bed.With the Extreme Off-Road Package comes skid plates and underbody shields to protect the battery pack, drive units, and other components.

    The Hummer EV seats five. The cabin is dominated by a 12.3-inch digital dash and a large 13.4-inch center infotainment screen.

    The automaker claims the Edition 1 pickup truck will have 1,000 hp, 11,500 lb.-ft. of torque (calculated at the axle, factoring gear ratio multiplication), and sprint 0-60 mph in 3 seconds and the peak torque output can be maintained up to 40 mph. That sports-car-grade acceleration requires the Watts to Freedom (aka WTF) mode: Activating this lowers the truck, conditions the battery, plays music, and coaches the driver when to accelerate to get maximum thrust. This approach essentially turns maximum straightline acceleration into a game. And this might resonate with some people given that the Hummer EV is the first vehicle to use Epic’s Unreal Engine for its graphic displays, a software platform associated with first-person shooter computer games. The SUV peak output is about 830 hp and up to 11,500 lb.-ft. of torque. GM claims maximum acceleration for the SUV is 3.5 seconds 0 to 60 mph.

    The Edition 1 pickup uses a 24-module battery pack to achieve 350-plus-mile range. GMC representatives explained that changing the pack configuration, by reducing the modules, can be done to serve the needs for other Hummer trims. Those other trim levels will also dial back the price and power output. The shorter SUV uses a 20-module battery pack.

    The batteries use a nickel, cobalt, manganese, aluminum (NCMA) chemistry. The Hummer EV is the first GM vehicle to use a wireless battery management system. This approach, as GMC explained, helps optimize both performance and longevity. The EV3X also uses three motors, but it produces 800 horsepower and 9,500 lb.-ft. of torque when factoring gear multiplication. The two-motor EV2X has 625 horsepower and 7,400 lb.-ft. of torque. Both the EV3X and EV2X have an estimated 300-plus-mile range. Coming in spring 2024 is the EV2. This more affordable version has two motors, with 625 horsepower and 7,400 lb.-ft. of torque. Range is estimated to be more than 250 miles.

    The Edition 1, EV3X, and EV2X are 800-volt DC fast charging capable. GM says these can take on 100 miles of range in just 10 minutes. The EV2 is 400-volt DC fast charging capable. The SUV follows a similar trim designation and performance ladder. These charging claims relate only to the still scant public DC fast-charging venues, not the more common 240-volt (Level 2) charging, which would take about 4 hours to get a 100 miles’ worth of range.

    There are a couple of features available on the EV2X and higher trims to enhance the vehicles’ off-roading potential: Extract Mode and Crab Walk. The adaptive air suspension allows the ride height to be controlled by the driver or adjusted automatically. For example, the truck can be lowered to make it easier to get into and out of. It also can lower on the highway to improve aerodynamics and energy efficiency. And Extract Mode allows the driver to raise the ride height by 6 inches to assist in very limited situations where ground clearance is needed to traverse an obstacle. Otherwise, the suspension can compress a long 13 inches.

    In Auto mode, the four-wheel steering system can turn the rear tires in the opposite direction of the front tires at low speeds to aid maneuverability. Taken to an extreme, the Crab Walk feature uses the four-wheel steering capability to enable the vehicles to move diagonally by angling all wheels in the same direction. This could prove to be handy in navigating tight trails, such as when moving away from a tree on a narrow section, and for maneuvering in tight parking situations.

    The next-generation Super Cruise is optional—a driver assistance feature that offers hands-free driving with automatic lane changes on 200,000 miles of compatible roads. It is available with up to 18 camera views—including a waterproof undercarriage camera—to help with off-roading and parking.Information on other safety systems has not been released.
