"Interestingly, the GMC Hummer EV Pickup was spied next to a Ford Mustang Mach-E, which is The Blue Oval’s compact electric crossover with a few Mustang-inspired cues. While it’s not entirely inconceivable that Ford was testing the Hummer EV Pickup against the Mustang Mach-E, it’s more likely that Ford is interested in studying the Ultium battery and Ultium Drive motors found within the new Hummer EV model. This information could prove useful as Ford develops its next-generation Ford F-150 EV, along with other models like a hypothetical Bronco EV."
