GMC didn't just cover the bed and call it a day. The 2024 GMC Hummer EV SUV completed the reborn Hummer lineup that began last October with the reveal of the Hummer EV pickup. Buyers already dead set on getting a truck or an SUV probably know which one they want. But there are many potential customers still on the fence. Making a final decision can be difficult but they need to know one critical thing: GMC designers didn't just cover the truck's bed with a roof and go home. There are several key differences between the two EVs that could make the buying decision easier. Heck, the First Editions already have different power ratings and performance times. Both are impressive machines but the tiny details might matter more.
