The GMC Hummer EV will cost you more to charge from empty to full than just about any other production electric vehicle on the market today. However, this is because it has a massive battery pack. Vehicles that have larger gas tanks cost more to fill up than those with smaller tanks. This certainly isn't rocket science.
That said, the Hummer EV is huge, it's far from slippery, and it uses its large battery pack and electric motors to crank out obnoxious acceleration and torque. For this reason, this electric pickup truck is certainly going to consume more than its peers, but that's a different story for a different day.
