Company’s today have learned from the showmanship of the late Steve Jobs in ending a presentation with a punch. That has become true even for car shows. At the Detroit Auto Show, also known by its longer name, the North American International Auto Show, Ford already had a few cars to reveal. It may, however, just saved the best for last. No actual car was shown, of course, but Ford did show off a video revealing the upcoming Mustang Shelby GT500, poised to breach the 200 mph barrier next year.
