New full underbelly panel for my 93 festiva - Fuel Economy, Hypermiling, EcoModding News and Forum

Finished it this evening when I got home.

Front

Front underside

Drivers side under door

Rear

Materials used.
1 1/2 pieces of coroplast ($17)
1" tornilo screws (1box $4)
1" diameter washers (on hand)
20' of flooring metal ( had it on hand)
10' of L shaped aluminum track (had it on hand)
Card board used to pattern (leftover from a recent tub install)
Utility knife (I use this for work so no cost to me here)
Time spent= 8 hours
Total money invested= $21.00
Miles to recoup investment= ?

Upon taking it out for its first test drive it was awesome how little throttle it needed to maintain 60+ mph. It feels similar to the throttle I was using at 57 before just as a guess. Hopefully this will put me on my way to reaching that 60+mpg tank that has so narrowly eluded me thus far.

I like the sound of almost no throttle to keep it at 60 mph

Nice work, but the middle of it looks a bit loose. THe festiva isn't very aerodynamic to begin with, but the low throttle at 60mph is encouraging. Keep up the good work.

Its not lose, it just has a few things that it is being forced out by slightly. I felt it would be more advantageous to allow it to push out (less than an inch and secure) rather than make cutouts to allow for pure conformity. I guess time will tell
