Wired on the Race to Build the Supergreen Car

Wired has a really interesting article on the Automotive X PRIZE. I'd rank it as one of the best AXP articles I've seen from the point of view of "a good read". This one gets into some details on a few of the teams. It also covers a lot of the design tradeoffs that have to be made to reach the fuel efficiency, marketability, and carbon emissions standards of the competition. There's also a link to the the X PRIZE Ecosystem, a brief review of some of the innovation prizes that are out there.
