The 2011 Kia Optima Hybrid is estimated to get a solid 40 mpg on the highway. But a team of “hypermiling” specialists—who utilize special driving techniques to boost a vehicle’s fuel economy—just finished a trip through every Lower 48 state while averaging 64.55 miles per gallon. They broke a Guinness World Record in the process.
Wayne Gerdes, of Illinois, and New York’s Chris Bernius teamed up to complete a 14-day, 7,899-mile drive that touched each of the contiguous 48 states—and that, most impressively, required just 5.5 fill-ups at the pump. Throughout their journey, in a standard-issue 2011 Kia Optima Hybrid, the drivers averaged 64.55 mpg, and 1,418 miles on the road before having to refill the tank.
How did they do it?
