One of my favorite stories I've ever written involved an impromptu test drive through the Detroit Auto Show with a leader who was soon to become the richest man in China. Four shows later we recreated the drive.
Though BYD Auto made a big show of their own fleet of electric vehicles, their hard-to-believe battery technology is more likely to end up in your driveway under the hood of a domestic.
BYD Auto debuted their E6 full-electric crossover, reportedly capable of a 250-mile trip on just one full charge, putting it ahead of any electric car for sale or announced. We'll probably never see it.
