Racing at 6,786 miles per gallon

The winners of the European Eco-Shell Marathon 2006 weren't the fastest but they were the most fuel efficient. Teams had to battle changing temperatures and wind conditions and use the least amount of fuel after completing seven laps of the Nogaro Circuit in southwest France.

The first 27 teams broke the 1,000-kilometer-per-liter (2,825-mile-per-gallon) barrier, according to officials.
