Hi,

A quick update: I added a bit more duct tape to seal the hood joint with the top of the headlights. This tank is looking very good: ~370 miles with ~1/4 tank left = ~490 miles on the tank (!!!) = ~49mpg! Woohooo! That is simply amazing...these front end aero mods have added ~65-70 miles per tank, and they will have added ~5mpg to my pre-mod best!

[Edit: This is on my regular commute, so it is a round trip -- all the downhills are uphills in the other direction; and traffic is hardly ideal. There is no way I could do any pulse + glide...]

My lifetime average is 37+mpg -- and this tank looks like it will be 10-12mpg better than that. I'm still flabbergasted...

My working theory is that covering the fog lights has smoothed the air flow coming off the sides of the chin spoiler; possibly helping air to flow out an around the front wheels?

I want to make a pan for the rear undercarriage behind the axle -- ideally, this could be structural, and the new space would add a fair amount of volume to this car's Achilles Heel -- storage space. Both the rear bumper fascia and part of the metal frame hang down an form sharp edges across the air flow.
