Thanks Arragonis, but I can't engine off coast in my car, so I'm just curious to see what i could expect if i aeromodded my car and drove normally.

The largest increase i have seen is Phils' ( Aerohead ) truck that dropped from .44 down to .153 and gained around ten or so miles per gallon .

So if I drop my stock Cd of .31 down to AeroCivic numbers* ( .17 ? ) then i can expect a averaged gain of a how many miles per gallon without EOC ? I can usually get around 40 - 44 MPG on long highway trips with no stops, so perhaps i could crack 50 MPG ?

From what Phil had said in a previous post, it looks like i could gain maybe six or seven mpg tops, but then i see that 3 Wheeler gained nearly 10 mpg with his boattail addition, and this was on a car that had a lot less wake than the car that i have, and the test consisted of freeway driving with no EOC ( I'm assuming )

So a little confused here.

( * BTW, Me and Basjoos have the exact same car, but mine is automatic. )
