Sponsored Links As might be expected of such a high-tech vehicle, the upcoming GMC Hummer EV pickup has more interesting technological features than most would guess. Many of these are designed to enhance the supertruck’s off-road performance, including something called Dynamic Bump Zone. Dynamic Bump Zone is one of several technologies discussed in an interview the Detroit Free Press recently conducted with Mike Colville, Senior Manager, Electric Vehicle Integration at General Motors. Colville is a tech guy, but he’s also very much an off-road guy. In fact, he was an off-road racer, competing in a self-built 700 horsepower four-wheel drive contraption for eight years until GM transferred him to China in 2015.
