It may not blow your hair back like an illegal street race but hypermiling also won’t put your life, or your license, at risk. It’s just a fun and challenging game to save money.
The goal of the game is simple: beat the EPA-estimated fuel efficiency numbers for your vehicle. But since many people find this too easy, the goal simply becomes to see how high you can go!
There are distinct hypermiling techniques for accomplishing the goal. The number one technique is slow and easy acceleration. You use considerably more fuel getting up to speed as compared to maintaining speed. That being said, traveling beyond 55 mph will also cause your efficiency to diminish.
Another technique is to eliminate unnecessary braking, which is largely caused by lack of awareness of traffic. A lot of people accelerate madly without realizing that they may need to brake soon. Hypermiling is all about anticipating what’s ahead because braking and then having to accelerate again uses more fuel.
There are other ways you can save fuel. For instance, avoid idling for too long. Underinflated tires may also cost your more fuel. Coasting down hills or coasting to upcoming red lights can be helpful.
