One factor which has a significant effect on vehicle fuel consumption is the rate at which the vehicle is accelerated. Quantitative and qualitative studies have shown that more rapid and/or more frequent accelerations result in increased fuel consumption. The EPA has conducted a study to quantify the effects of operating a vehicle at different acceleration rates. The test involved accelerating the vehicle at a constant acceleration rate to a speed of 55 mph, and maintaining the 55 mph speed until total distance traveled equaled one mile. Conceptually, this may be viewed as entering a freeway system with different acceleration rates.
