Since the advent of the hybrid at the turn of this century, an increasingly large group of hardcore fanatics have taken up hypermiling. For the uninitiated, hypermiling is the practice of using modified driving techniques to get the maximum possible fuel efficiency. There are hypermilers who claim to get over 100mpg from their Priuses and Insights. The problem is that techniques like pulse and glide involve significant fluctuations in speed. By accelerating quickly and then coasting for long periods using regenerative braking to recharge the battery as much as possible and then repeating ad nauseum, they minimize the load on the engine. This is fine when a vehicle is driving in little or no traffic. Unfortunately, when there are other cars around, an extreme hypermiler can pose a real impediment. Differences in speed are often a source of accidents and people who aren't driving hybrids won't want to be stuck behind someone coasting along. There is nothing wrong with trying to maximize fuel efficiency and everyone should be trying to drive efficiently. However, even hypermilers need to be cognizant of other drivers around them and avoid being obstructive.

Even veteran hypermilers will probably find something worth remembering in this list of 100 ways to increase a vehicle's miles per gallon. Sure, the list starts with the basic, heard-em-before ways to get more distance out of the fuel in the tank of the car you already drive, but how many of you have considered an "ice vest" instead of air conditioning?

If you're just getting into the hypermiling game, EcoTrekker's 100 items (made up of tips, links to other articles to read, and online resources) should provide you with plenty to practice as you drive. Some of my faves are #9 (finding the route with the least amount of traffic and stop signs, even if it's slightly longer) and #77 (ridge riding to avoid puddles). Oh, and #53. :) Missteps in the list include #73 (the Lexus GS hybrid should not be on anyone's list of best cars to hypermile in) and #12 (only works if you already drive a hybrids).
