A MUSTANG AND an Explorer wheel into a Detroit factory. This is not, tragically, the beginning of a joke. Rather, it’s a new (and weirdly ‘80s themed?) Ford promo video. Lightning flashes, synthesizers synthesize, and we behold the carmaker’s next great machine, to debut in 2020: an all-electric SUV, good for 300 miles of driving between charges, called the Mach 1. Well, we behold a glowing sign that reads “Mach 1″—Ford has yet to debut the car, even as a concept or prototype. The fog and light-infused video will have to do for now.
