New book recounts MPG competition in fascinating detail

In 2007, more than 200 teams set out on an ambitious automotive undertaking. The X Prize Foundation announced it would create a $10-million competition open to anyone who could build a safe, mass-producible car that achieved 100 miles per gallon equivalent. AutoblogGreen followed the competition in real time, but the grueling three-year adventure has now been recounted in fascinating detail by author Jason Fagone in Ingenious, a new book on sale this month.

As our coverage of the 2010 Automotive X-Prize comes to a close, now is as good a time as any to recap some of the events that led to the crowning of this year's champions. From the beginning, many of the X-Prize entrants likely knew that the grueling competition would cut the massive field of participants down to almost nothing, but they tenaciously competed for the title with the goal of winning always front and center. Setbacks along the way led to the early disappearance of several teams, bu

The on-track testing portions of the Automotive X-Prize are over with, and the vast majority of teams have been eliminated from contention. However, the $10 million in prize money won't be handed out until September 16. Before those checks are signed, the remaining competitors will have to complete a drive cycle on a dynamometer at the Argonne National Labratory. The dyno results will be averaged with the on-track results and the final numbers will have to top the 100 MPGe values originally set

The Finals Stage of the Progressive Automotive X-Prize is taking place this week and, if nothing else, the organizers and teams involved now really know what they're doing. Most everything is running well and the teams "sailed" through tech inspection, in the words of Eric Cahill, the X-Prize's senior director.

We've told you about the University of Kansas EcoHawks before. They're a group of engineering students from KU who are trying to build a car that will get 500 miles per gallon-equivalent. One of their ongoing projects is a 1974 Volkswagen Beetle that they've converted to be a series hybrid running on lead-acid batteries. Until recently, the car was charged by a biodiesel-powered generator, the biodiesel being made from waste vegetable oil (WVO) sourced from campus. Now, the mechanical engineerin
