Tuesday night, and after a lengthy Bowl campaign that included a Super Bowl advertisement, GMC introduced its new Hummer EV to the world. The Hammer EV is the first promised by General Motors for new electric vehicles, but for real, the last time GM made such a promise. It is the company’s first battery electric vehicle since the Chevrolet Bolt EV, and represents a complete Volt face For the automaker.
After all, if an inexpensive, compact, efficient BEV would not suit American consumers, perhaps a 1,000hp (745kW) super truck would do the trick with a 0-60mph time of three seconds. Oh, and $ 112,595 price tag, at least to begin with.
And it’s a big one: 216.8 inches (5,507 mm) long, making it slightly shorter than the Escalade that you all hate. It is 86.7 inches wide (2,201 mm) without counting mirrors, or 93.7 inches (2,380 mm) with them. And we are pretty sure that it is 81.1 inches (2,060 mm) long. I have no idea about its control in pounds, but it seems to start at six.
The new Hummer EV is the first vehicle to use GM’s new Ultium battery and Ultium drive motor family. And the boy uses it. There are 24 battery modules. Although GMC will not give us an accurate usable kWh number until it has EPA certification, when it unveiled the Ultimate Pack in March, it told us that the 24-module pack would total 200kWh. GMC states that the Hummer EV should be given a range of 350 miles (564 km). And because the vehicle uses the 800V architecture, it can fast-charge up to 350kW, adding 100 miles (160 km) of range in 10 minutes, we’re told. (As a reminder, GM recently partnered with eVigo to deploy 2,700 new DC Fast Chargers.)
There are a total of three permanent magnet electric motors – one powering the front axle and one pair in the rear, each driving its own wheel. If the sound of a thousand horsepower is not large, the GMC coats the torque of 11,500lb-ft, but it is on 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 in engineering explained Calculates about 1,000lb-ft on motors.
