GM is referring to the vehicle as the GMC Hummer EV electric super truck and with the specs it has, the name (super truck) seems appropriate. How do these figures sound?

1,000 HP
11,500 pound-feet of torque
0 to 60 in 3 seconds
Of course, that torque metric is disputable and we've seen similar wild claims like that in the past, so just ignore that figure for now, as it's not really comparable to any torque claims for conventional gas or diesel pickup trucks.

According to GM, the GMC Hummer EV will be available starting in Fall 2021. However, it will make its official debut on May 20, 2020:

The GMC HUMMER EV will be revealed on May 20, 2020 and built in Michigan at General Motors' Detroit-Hamtramck assembly plant.

The vehicle will also appear in an upcoming Super Bowl spot:

The 30-second TV spot is scheduled to air during the second quarter of the big game. The spot highlights the anticipated performance of GMC's all-electric super truck, which will generate remarkable metrics in terms of horsepower, torque and acceleration while providing incredible on- and off-road capability. All of this is combined with the vastly reduced noise and zero emissions inherent in the operation of an electric vehicle.
