GM says neither they nor any car maker in the world knows how to meet that standard with existing technology. In order to do it, you're going to need a different kind of car. They believe that these cafe limits have handed the vault, a business case.
Jonathan Rauch, of the Brookings Institution and the Atlantic Monthly, talks with EconTalk host Russ Roberts about the evolution of the Chevy Volt, GM's planned electric car. Due to the transparency of GM's effort, Rauch was able to spend a great deal of time on site at GM writing a piece for the Atlantic Monthly on GM's plans and hopes. Rauch discusses the huge risks, GM's past failures, and GM's hopes that the Volt might change the company's culture. The conversation closes with a discussion of competitors and the implications for energy policy.
