“In this case, the approach created the 2024 GMC Hummer EV SUV. It’s the fraternal twin of the Hummer pickup, and everything from the rear doors forward is identical. An 8.9-inch wheelbase reduction shrinks cargo space relative to the pickup but keeps rear-seat space intact. The wheelbase might be shorter, but let’s provide some perspective: The SUV’s 126.7-inch wheelbase is still vast, coming within half an inch of a 1973 Lincoln Continental’s. The Hummer pickup weighs 9640 pounds (a weight that required a trip to the truck scales because it was too much for our scales), but the SUV isn’t quite as heavy: 8660 pounds. Still, you may want to think twice before crossing bridges rated at four tons. The weight loss comes primarily from the SUV’s smaller battery pack. Instead of 24 battery modules, the SUV has just 20 packaged below the floor, and that low-down mass leads to a stable feel. GMC estimates up to 314 miles of range, but the 170.0-kWh pack delivered 250 miles of range in our 75-mph highway test.
