If someone told you there was a way to improve your gas mileage by as much as 55 percent without making any modifications to your car, you’d probably think they were nuts. Now imagine it’s the U.S. Department of Energy telling you that. Some people might still hear the “nutjob” alarm going off, regardless. But according to studies they’ve conducted, you can dramatically improve MPG simply by driving the speed limit and—here comes the hard part for some—letting go of certain aggressive driving behaviors.
This is just one of a series of behavioral adjustments that many are adopting as gas prices continue to creep higher and higher. It’s called hypermiling, and it’s become something of a sport for those obsessed with getting hyper mileage from their vehicles. While there are plenty of unsafe techniques that people have put into use like removing their side view mirrors to eliminate drag or turning off their engines while coasting downhill, there are many other perfectly safe methods that’ll have a beneficial impact on your mileage.
In the end, common sense prevails. There are no real “secret” hypermiling techniques. As long as you keep in mind that your behavior behind the wheel has the biggest impact on your MPG, you can realize some sizable savings.
