Re: Lowering your car in order to increase fuel economy
This trip started OK but I began to get concerned when I was dropping below my target FE at the various milestones on my route. I was downright pissed when my IGN off coasts were ending way too early. I almost pulled over to check if I had a low tire. But when I got to work I checked weather.com and found that my normal 9MPH tailwind had turned into a 6MPH headwind today. Not bad results considering a net 15MPH increase in wind speed.
- 3/8/06 Morning Commute: 26F, Dry roads, 6 MPH head wind, engine on 70% of distance, 54.29 MPG
- Closest matching pre drop data:
3/1/06 Morning Commute, 28F, Dry roads, 9 MPH tail wind, engine on 69% of distance, 55.00 MPG
- Current Tank FE as measured by SuperMID
447 miles, 51.80 MPG
It's amazing to me how much you use wind to your advantage. Wind is never that consistent here, or if it is I never notice it.
During the winter here the prevailing winds are usually from the North. So most of my drive to work has a tailwind but its payback time on the evening commute. That is part of the reason why my FE differs on each leg. Other reasons are more traffic on the evening drive and +200 ft elevation difference.
Also be aware that when I say tailwind/headwind, that doesn't mean a perfect tailwind/headwind. It means that the wind usually at my back/front as my route changes direction several times. As the crow flies I drive SSW in the morning and NNW in the evening.
During the spring, summer and fall, the winds are more variable in direction and speed.
