OSHAWA, Ont. (October 27, 2020) – The 2022 GMC HUMMER EV Edition 1 will be the first vehicle in production with GM’s all-new Ultium battery architecture and will offer impressive on- and off-road features and broad range of vehicle dynamics and performance features. Initial Canadian availability fall 2022.

This new architecture provides the framework to integrate advanced technologies for optimal driving range and — in the case of the HUMMER EV — will enable performance and capabilities that would not be possible with a conventional vehicle architecture and propulsion system.

The 24-module Ultium battery pack and three-motor Ultium Drive system will provide this all-electric supertruck offering the best-in-class horsepower* output.

“As the first of GM’s next-gen EVs, the HUMMER EV will fundamentally alter conventional off-road and truck paradigms,” said Ken Morris, GM vice president, Autonomous and Electric Vehicle Programs. “It will also debut new technology including our all-new Ultium batteries, Ultium Drive units and the industry’s first wireless battery management system.”

Ultium cells

Ultium batteries are unique in the industry because of their large-format, pouch-style cells, which can be stacked vertically or horizontally inside the battery pack. In the HUMMER EV, two layers of vertical cell modules will be used to produce a combined, 24-module pack offering a GM-estimated range of 560+ kms7.

In addition to power and range, the Ultium battery pack will contribute to the HUMMER EV’s driving dynamics and structure. The pack’s low mounting position in the chassis contributes to a low center of gravity, enhancing the vehicle’s overall feeling of control and stability. The compact construction of the Ultium battery pack also contributes to HUMMER EV’s ideal off-road proportions, including a short front overhang and short front breakover angle.

With GM’s state-of-the-art Nickel, Cobalt, Manganese, Aluminum (NCMA) chemistry, HUMMER EV’s Ultium batteries will have some of the highest nickel and lowest cobalt — a rare and costly material — content of any large format pouch cell. The breakthroughs of the Ultium chemistry allow GM to use 70 percent less Cobalt than GM’s previous generation of EVs.

HUMMER EV will also be the first vehicle in GM’s lineup to feature its wireless battery management system, which maintains balance within the truck’s battery cell groups for optimal performance and battery longevity.

Electrifying off-road

This is the first truck that we have ever designed around an EV propulsion system,” said Adam Kwiatkowski, GM executive chief engineer, Global Electric Propulsion. “Designing the truck and the propulsion system together enhances HUMMER EV’s unique performance capabilities, while also making this the stiffest truck GM has ever built.”

The 2022 GMC HUMMER EV’s design visually communicates extreme capability, reinforced with rugged architectural details that are delivered with a premium, well-executed and appointed interior.

Edition 1’s three electric drive motors within Ultium Drive will yield a combined GM-estimated 1,000 horsepower*, and when multiplied through the front and rear drive unit gear ratios, there will be more than a GM-estimated 11,500 lb.-ft.* of torque available at the wheels

The single-motor front drive unit will have a 13.3:1 fixed gear ratio and will offer an electronic lockable differential, capable of delivering up to 100 percent of the motor torque to one wheel, in case traction is lost on the opposite wheel. All four wheels can be fully synchronized for true e4WD propulsion.

Two rear motors contained in one Ultium Drive unit will independently power the rear wheels through a fixed gear ratio of 10.5:1, with the capability of varying torque output to each wheel to optimize traction in off-road driving and highway-driving conditions. Motor output can also be synchronized to simulate a locking differential.

The system’s pure electric propulsion holds peak torque much longer, through a wider speed range (up to 40 mph) than even diesel engines, which is optimal for off-roading and also thrilling on road. For straight-line performance, the Ultium batteries and Ultium Drive will offer enough power to enable the Watts to Freedom performance feature, launching the HUMMER EV up to 0-60 mph in approximately three seconds (based on GM estimates).

Public DC Fast Charging

HUMMER EV will have the ability to take advantage of the industry’s fastest 350 kW DC fast chargers4. The vehicle range will be a GM-estimated 560+ kms7, based on preliminary testing, with a unique ability to switch its battery pack from its native 400-volts to 800-volts for charging. A disconnect unit and mechanization within the pack enables the battery to switch from “parallel” to “series,” allowing it to add nearly 160 km of range* in ten minutes of charging.

Driven by next-generation EV propulsion technology, the GMC HUMMER EV will be the first fully electric addition to GMC’s lineup and will bring GM another step closer to an all-electric future.

The Ultium battery system will control the electrical currents at the charging station via clever algorithms that ramp down the current and switch to the other half of the pack, when necessary, and increase the rate of charge. The charging system is also designed to support legacy 400V charging infrastructure, without the need for a converter box or other accessories, allowing HUMMER EV to use a variety of charging stations.

HUMMER Family 2004

The HUMMER EV’s charging hardware will be complemented by in-vehicle and available smartphone apps that help customers find available charging locations and can even precondition the battery to get the most efficiency out of their upcoming charging session.

Energy Assist9

The HUMMER EV’s in-vehicle Energy Assist, also part of the myGMC mobile app8, will monitor the vehicle’s energy use, and sets up a charging schedule, preheating the battery en route to the charging station for optimal charging and learning to drive more efficiently to maximize range and more. It is accessible through the infotainment system6 and designed with a simple, intuitive interface with easy-to-understand icons.

 

Regen on Demand5, One Pedal Drive+

HUMMER EV is the first GMC vehicle to offer variable Regen on Demand5, a driver-controlled regenerative braking feature, which converts the kinetic energy of the truck’s forward momentum into electricity stored in the vehicle’s battery packs for maximizing the driving range.

This standard feature is compatible with all of HUMMER EV’s available drive modes. Unlike other EV regenerative braking features, Regen on Demand allows the driver to decide when and to what extent the system should be used. With the pull of a steering wheel paddle, drivers can even slow the vehicle to a full stop without engaging the brake pedal. If the driver anticipates the need to decelerate the truck, he or she can engage Regen on Demand before lifting off the accelerator pedal, for a greater measure of control.

HUMMER EV also features one pedal driving through a driver-selectable Terrain Mode, which provides low-speed, one-pedal control for driving over off-road terrain and obstacles.

Super Cruise6

The GMC HUMMER EV will launch with the latest version of Super Cruise6, a driver assistance feature offering hands-free driving with automatic lane changing on divided and compatible roads.

Super Cruise is the industry’s first true hands-free driver assistance system on divided and compatible roadsUnlike others, it uses two advanced technology systems – a driver attention system and precision LiDAR map data. Recent enhancements to Super Cruise include performance and ease-of-use updates including richer map information, improved software controls and user interface improvements to make Super Cruise more intuitive.

The HUMMER EV is the first full-electric vehicle in GMC’s portfolio and is powered by General Motors’ new Ultium battery system. Production begins in late 2021, at GM’s Factory Zero in Detroit-Hamtramck. Canadian production begins in the Fall of 2022 and will be sold through the GMC Canada Dealer network.
