Hypermiling wins Nascar race

The USA’s Nascar star Dale Earnhardt Jr drove (or coasted) to victory at Michigan International Speedway using hypermiling techniques. Junior drove his last 110 miles (55 times around the two-mile track) without refueling. His pit crew estimated that he’d need to refuel with about six laps to go but Earnhardt turned the engine off and coasted when the caution flag was out to stretch his distance. He was actually coasting when he crossed the finish line, and ran out of fuel almost immedieately after the win. According to Earnhardt he is not only one using these drive techniques to squeeze a few laps extra out of the tank.
