39.5 MPG in a sedan!! (1999 Plymouth Breeze with custom Kammback)

[bschloop]

My wife recently took my plymouth breeze out for a little 750mi jaunt to visit family. I had just finished a prototype "fastback" and this provided for a good way to test it on the highway. She got 39.5 mpg on the first leg of the trip, which was 370mi of highway/expressway 55/65 mph. Our best effort before ecomodding was 32mpg, so this was awesome. On the way home she averaged only 35mpg but this included driving around, Grand Rapids which could account for most of the loss. All in all I think she saved almost a full tank of gas!!
My other mods are: AC delete, Power steering delete, Wiper blades removed taped front wheel covers.

I got 39.74 this winter in my sedan. It is amazing what you can get in a full size car. I still need to fab a kamm back.

Have any pictures, bsch? That's pretty impressive, as a plymouth breeze doesn't have a very steep angle coming off the roof, so I wouldn't expect such an improvement. Great job!

I think actually that the AC and PS deletes also affected FE. I had been averaging around 31-33mpg an my mostly highway commute to work and back with just these. As for Pics, How do I go about posting them? I am much less adept with computers than with cars.

tried this, but the it seems that my connection is too slow. I will try again later at the library.

Photo is likely too large if it's not working via dial-up. There's a ~100 kb limit on attached images. Resizing down to approx 500 pixels wide will get it in the right neighbourhood.

That is a Awesome increase. Congratulations!

thanks, these pics are with the plexiglass window out, as I am preparing to turn it into a finished hatchback.

Very cool! Thanks for posting.

I don't suppose you did any tuft testing as well?
