On Tuesday night, and after a long teaser campaign that included a Super Bowl advert, GMC introduced its new Hummer EV to the world. The Hummer EV is the first of a promised onslaught of new electric vehicles from General Motors, but for real, unlike the last time GM promised such a thing. It’s also the company’s first battery electric vehicle since the Chevrolet Bolt EV, and it represents a complete volte-face for the automaker.
After all, if an affordable, compact, efficient BEV won’t find favor with American consumers, maybe a 1,000hp (745kW) super truck with a 0-60mph time of three seconds will do the trick. Oh, and a $112,595 price tag, at least to begin with.
And this one is big: 216.8 inches (5,507mm) long, making it slightly shorter than the Escalade that you all hate. It’s 86.7 inches wide (2,201mm) without counting the mirrors, or 93.7 inches (2,380mm) with them included. and we’re pretty sure it’s 81.1 inches (2,060mm) tall. I have no idea about its curb weight in pounds but would guess it starts with a six.
The new Hummer EV is the first vehicle to use GM’s new Ultium batteries and Ultium Drive motor family. And boy does it use them. There are 24 battery modules. Although GMC won’t give us an exact usable kWh number until it has its EPA certification, when it unveiled the Ultium packs in March it told us that the 24-module pack would boast a total of 200kWh. 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. (As a reminder, GM recently partnered with EVgo to deploy 2,700 new DC fast chargers.)
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. The company says that the different ratios between the front axle (13.3:1) and the rear (10.5:1) mean that wheel torque is more appropriate. However, Jason Fenske at Engineering Explained calculates that to about 1,000hp at the motors.
