Travel to the U.S. Shell Eco-Marathon. The challenge? High school and university students compete to see whose vehicle can go the farthest on the least amount of fuel – winners take home $10,000. Top teams are gunning for up to 2000 miles per gallon. Check in with the key players and be there at the finish line to see the most fuel-efficient eco-ride take home the prize. Meet up with “hypermiler” Wayne Gerdes, who can get eye-popping mpg numbers on just about any vehicle he drives.
