Team Name: Commuter Cars
Location: Spokane, Wash
Car name: Tango
Who are they? Commuter cars was started in 1998 as a father-son project by Rick Woodbury and his son Bryan. Rick has experience building, racing, and selling Porsches, and Bryan is known as a computer whiz. They've been building and selling Tangos--at $80,000 each--for decades, long before the Xprize competition was announced.
What they say will set them apart: In addition to achieving 100 mpg equivalent, the Tango aims to solve congestion by taking up only half a lane-- leaving the other half for a motorcycle or another Tango. In addition, the car is fast and fun to drive. But it would take widespread adoption of Tangos to really make a difference in congestion.
Field notes: The tiny Tango (which one member of a competing team dubbed "a two-dimensional car"), aced all its performance tests, never having to go back for a second try, where other teams had to worry about the 10-attempt limit in the Knockout round.
