Oxford's Word Of The Year

Hypermiling:

“Hypermiling” was coined in 2004 by Wayne Gerdes, who runs this web site. “Hypermiling” or “to hypermile” is to attempt to maximize gas mileage by making fuel-conserving adjustments to one’s car and one’s driving techniques. Rather than aiming for good mileage or even great mileage, hypermilers seek to push their gas tanks to the limit and achieve hypermileage, exceeding EPA ratings for miles per gallon.
