Well, this was the big week. The North Amer--sorry--Detroit Auto Show has arrived and everyone's eager to see the future of the auto industry in the shadow of last year's economic meltdown. GM is at the show with four fewer brands than a year ago, while Fiat brought Chrysler's new Italian step-siblings in to class up the joint. Meanwhile, the other domestic auto maker, Ford, seems to have owned this year's show. In to review the show as well as talk about some innovative new engine technology is Don Runkle, the CEO of EcoMotors. Peter De Lorenzo, the Autoextremist, and David Welch from BusinessWeek and Bloomberg News also join John McElroy in studio.
