In 2006, at the Honda Insight Marathon in Tonkawa, Okla., using driving tactics both mundane and exotic, Gerdes and his teammates went 2,254 miles on a single 13.7-gallon tank of gas. That's an average of 165 miles per gallon for a vehicle with an EPA rating of 60 city/66 highway. During one of Gerdes' runs on the 40-mile course, mpg peaked at 200.

Gerdes proved this recently when he put a visitor behind the wheel and talked him through a 30-mile trip to Chicago's O'Hare International Airport. The driver, previously untutored in the ways of hypermiling, averaged 51.2 mpg in Gerdes' 2005 Honda Accord, exceeding the EPA's highway rating for the vehicle by more than 50%.
