At the X-Prize competition, the team that designed the Edison2 concept car was able to get their lightweight automobile with innovative design and construction and not with simple green technology like an electric engine. However, despite using an old-fashion internal combustible engine, the 830-pound Edison2 is still able to achieve gas mileage of 102.5 MPG, winning it $5 million in the contest. Part of its achievement is due to its aerodynamic shape, use of lightweight materials, and according to Wired, “a small displacement engine burning E85 is sure to catch the attention of automakers.” According to the Edison2′s designer, “our â€©analysis â€©showed â€©that â€©the â€©only â€©two â€©absolute â€©virtues â€©in â€©auto â€©efficiency â€©are â€©light â€©weight â€©andâ€© lowâ€© aerodynamic â€©drag. â€©So â€©we â€©avoided â€©the â€©hundreds â€©andâ€© hundreds â€©of â€©pounds â€©of â€©batteriesâ€© needed â€©for â€©an â€©electric â€©and â€©chose â€©a â€©conventional â€©internal â€©combustion â€©engine â€©running â€©on â€©E85.”
Though the Edison2 won $5 million, its designer says that he spent more money to build the vehicle. The next step is to get the car’s technologies adopted by other carmakers to developing fuel-efficient, lightweight automobiles. Edison2 designer Oliver Kuttner is saying that he is looking at how to improve the car and make it safer as well.
