My sig is full...so I might as well move some of it into a thread and just put in a single link to the thread, right? From now on, I'll add things here and send people here to see them rather than trying to squeeze them into my sig.

This one has more detail about gear ratios and requires you to enter more data, but calculates more driveline data.

More on weight reduction, with
actual measured results:

When it's all said and done,
some cars can have a measurable FE difference of ~1% MPG per 1% weight change -- so, to get a 10% change in MPG, one would add/remove 230 pounds on a 2300 pound Civic. Other
cars may not respond to weight loss at all, such as a 2.5% MPG change resulting from a whopping 19 percent weight change.

http://www.gassavers.org/showthread....4033#post94033
- In summary: A draft at highway speeds extends to three times the length of the vehicle, resulting in a 2 to 3 second following distance behind standard sized tractor-trailers -- that's not close, probably further than you were going to be anyway.
