1996 Honda Civic LX fully optioned no weight reduction
Coefficient of drag:
It's kinda a piece of ****, but eventually it will get there. . .
If you are reading this I'll go ahead and tell you this now:
If your car is a stick, it doesn't really matter what the hell the EPA rating is or the crazy mods you plan to do. They do help, but the way you drive is so much more important:
Look up "BSFC chart" for your style engine so you can efficiently pulse and glide (and make sense of what the hell PnG is and why it works)
Try not to use the brakes whatsoever
Do not ever come to a full stop
In town pulse and glide and turn the engine off when throttle isn't needed.
On the highway pulse and glide but throw the car in neutral w/o shutting it off.
This alone I went from 40mpg combined to 59mpg.
