My parents live in a rural area and I help them shop for a month at a time. My car regardless of model is always loaded so it sits lower. On the steady ride home all my vehicles seem to get better fuel economy. According to an engineer friend of mines he saw a lower car poked a smaller hole through the air. So, less air under the car and wind resistance.
My assumption was that the firmer springs allow you tot ake on and off ramps at higher speeds, so you tend to coast more and conserve more energy when merging.
My next mod is to get some rain gutters, cut them diaginally, then mount them under my front to further restrict air movement under my i2. Ive attached yard edging to the bottom of my geo metro bumper edge and it helped me to get over 50mpg in that car.
