The oversized Hummer EV pickup is an absolute monument to excess. However, the large SUV is speed-governed at 112 mph (models with optional mud terrain tires are limited to 105 mph). It was a good call by GMC engineers, considering the Hummer EV is a 4.5-ton freight train running on 35-inch mud-terrain tires. Because it accelerates so viciously off the line, the Hummer EV hits 110 mph in just 9.7 seconds –well before a quarter mile and crosses the finish line in 11.6 seconds at exactly — you've guessed it – 111.9 mph. For the final second of the run, we can imagine the driver just sitting there, right foot mashed into the floor, watching the digital speedometer sit at 112 mph.
