The all-new GMC Hummer EV takes the latest technology and applies it to a battery-driven off-roader, conquering the trail with electrons alone. In order to put those electrons to use in the most effective manner possible, the GMC Hummer EV is equipped with an AAM TracRite EL Electronic Locking Front Differential differential.
Similar to vehicles equipped with an internal combustion engine, the GM Hummer EV utilizes the AAM TracRite differential to split the power from a single electric motor to drive both wheels on an axle. The AAM unit features the company’s electronically controlled locking feature, which acts as a complement to the virtual locking utilized in the two-motor rear axle. Up front, the AAM differential can lock both front wheels to turn at identical speeds. Upwards of 100 percent of available torque can be sent to either the left or the right wheel, thus enhancing traction of the fully electric four-wheel-drive system.
“AAM’s TracRite EL Electronic Locking Differential is a workhorse differential that delivers power from the electric motor on the road and has the capability to increase traction off road,” said AAM Chairman and Chief Executive Officer, David C. Dauch. “AAM’s long history with industry-leading driveline systems coupled with award-winning EV technology enables differential technology that enhances the experience for drivers looking for exceptional vehicle performance both on and off road.”
Further off-roading specs for the GMC Hummer EV include a maximum ground clearance of 16 inches for SUV models and 15.9 inches for pickups, with a max approach angle of 49.6 degrees for the former and 49.7 degrees for the latter. Max suspension travel is set at 13 inches.
As a reminder, the GMC Hummer EV is offered in two body styles, including a pickup and an SUV. Both are based on the GM BT1 platform, and come powered by the GM Ultium Battery and GM Ultium Drive technologies. Multiple powertrain configurations are offered, with peak output rated between 625 horsepower and 1,000 horsepower. Production will take place at the GM Factory Zero facility in Michigan (previously known as GM Detroit-Hamtramck). The first units will ship later next year.
