The new Hummer EV is the first vehicle to use GM's new Ultium batteries and Ultium Drive motor family.
That should give the Hummer EV a range of 350 miles (564km), GMC says.
And because the vehicle uses an 800V architecture, it can fast-charge at up to 350kW, adding 100 miles (160km) of range in 10 minutes, we're told.
There is a total of three permanent magnet electric motors—one powering the front axle and a pair at the rear, each driving its own wheel.
If a thousand horsepower doesn't sound big enough, GMC quotes 11,500lb-ft of torque, but that's at the wheels, not the motor.
Since each rear wheel has its own motor, there is no need for a rear diff, but software replicates that effect when needed.
As is the trend, the Hummer EV will at first only be available as a fully loaded Edition 1, which starts production in late 2021 (with deliveries beginning in early 2022, we expect).
In fall 2022, the Hummer EV3X becomes available, nearly as feature-packed but also slightly cheaper, at $99,995.
GMC says it will be another six months after that for the $89,995 Hummer EV2X, which loses one of the rear electric motors but keeps the air suspension and four-wheel steering.
