Fuel Saving Tips
It's no secret that higher wind resistance upon your vehicle hurts your fuel economy. However, what many people may not realize, and test have proven this, is that aerodynamic drag increases exponentially as headwind/vehicle speed or both increase. For most vehicles, the optimal speed for maximizing fuel economy is between 40-50mph. As you go faster than that, the aerodynamic drag increases at an increasing rate to your speed. Popular Mechanics ran a test of a Toyota Camry once. At 45, it achieved 35mpg. At 55, it was about 30, and at 65, closer to 25mpg.
