Imagine, if you will, taking a sheet of paper and cutting it in half. Now take one of those halves and cut it in half again. Now keep repeating the process. As you keep cutting, the difference in the size of the subsequent pieces gets progressively smaller. This simple example is a demonstration of why continuing to increase the fuel mileage of a vehicle has less and less impact once you get beyond about 35-40 mpg.
Time for a bit of a math lesson. The amount of fuel consumed by vehicle is determined by dividing the number of miles driven by the miles per gallon. With the mileage being in the denominator, as it grows at a linear pace, the overall result gets progressively smaller. This is what’s known as a geometric series. One last example: imagine you have a pie that represents the amount of fuel you use to drive a certain distance at a given mileage. Continue reading after the jump to find out what happens to the pie.
