The automaker claims the Edition 1 pickup truck will have 1,000 hp and 11,500 lb.-ft. of torque (calculated at the axle, factoring gear ratio multiplication), and will sprint 0 to 60 mph in 3 seconds, putting it in rare performance company. The peak torque output can be maintained up to 40 mph.
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. That sports-car-grade acceleration requires the Watts to Freedom (aka WTF) mode: Activating this lowers the vehicle, conditions the battery, plays music, and coaches the driver when to accelerate to get maximum thrust. This approach essentially turns maximum straight-line acceleration into a game. And this might resonate with some people, given that the Hummer EVs are the first vehicles to use Epic’s Unreal Engine for its graphic displays, a software platform associated with first-person shooter computer games.
The Edition 1 pickup uses a 24-module battery pack to achieve a 350-plus-mile range. GMC representatives said 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. GMC says this approach helps optimize performance and longevity.
The EV3X pickup also uses three motors, but it produces 800 hp and 9,500 lb.-ft. of torque when factoring gear multiplication. The two-motor EV2X has 625 hp and 7,400 lb.-ft. of torque. 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 hp 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. The SUV boasts a tight 35.4-foot turning radius. 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.
