Hypermiling is a term used to describe practices that save gas. Many of these techniques are inconvenient and, at times, even impossible. But some of these techniques are showing up in one of the most unusual places – the NASCAR track.

Dale Earnhardt, Jr. recently won the race at the Michigan International Speedway. During the race, he used one common hypermiling technique - coasting. This was most noticeable because he drove for the last 110 miles, or 55 laps around the track, without refueling. The last time he stopped, his pit crew told him he should refuel when he had about six laps left to go. But Earnhardt was able to avoid one last fueling stop by allowing his car to coast when the caution flag was out.

As an even bigger surprise, he coasted across the finish line. Apparently, he was basically running on fumes because his car ran out of gas just a few seconds afterwards. Earnhardt Jr. hasn’t had a NASCAR victory since May 6, 2006.

But Earnhardt isn’t the only one on the circuit who is trying to drive more responsibly with regards to the environment. “Everybody’s doing it,” he said in an interview with ESPN.

If you’re driving one of the many Ford cars on the market today, you can employ hypermiling in your daily habits, too. If it’s good enough for NASCAR drivers, it’s certainly good enough for you!
