5. Driving 55, Will do More than Just Keep You Alive

There are many reasons why driving at the magic speed of 55 logs better fuel economy. One, this is assuming you are on a highway, which produces better fuel efficiency by reducing the gas guzzling effects of inner city stop-and-go traffic. Two, as most vehicles increase speeds beyond 55 they burn more fuel. This is due to increased engine effort, heat, air, and tire resistance. According to the American Council for an Energy-Efficient Economy, a vehicle will burn 10 percent more fuel at 60 mph, and up to 25 percent more at 75 mph. Another interesting tidbit to keep in mind, is that when a vehicle is developed from a manufacturer, it is designed to log optimum fuel economy during tests from the EPA, which range from 48 to 60 mph (the speed range for the highway portion of the tests).
