Go to the "65 efficiency mods" link in the top of the page. There are many things there that are already proven to increase 1-3mpg or far more. Take any of those mods and make a product out of it. Well even help you improve that product! And if it's well made at a good price that justifies the return investment in less fuel costs, some of us here would even be happy to buy it.

A lot of people here don't have the skills or resources to make something like a kammback with the fit or finish that would pass the "wife approval test." Some people want more mpg, but care to much about what other people think about them to tape cardboard and coroplast to their cars. If you made a molded plastic kammback for example that looked oem enough, then you have a market to sell it.

My Kia is long gone. I no longer do the long driving route. I test our Ford Focus when possible, with various materials, shapes, angles and placements. ***You who thrive in this ecomodder atmosphere could be a lot of help!***
A friend who is a metalwork craftsman is helping manufacture the blade. It is aluminum and mounts off the front license plate (at least on the Rio, Focus, Prius and other models we are testing). We call it the GasBlade.
Would love to hear what you think. Could see about making my units accessible (with permission already from the administrator here at ecomodder). Am trying to add pics (as attachments... hope it works). Pics and video clips are accessible at a crowdfunding site if you would like to view the gallery there (again, this is with permission from admin). GasBladePatent | Indiegogo

Perhaps you finally released the parking brake,as your mileage improvement is not attributable to the 'GasBlade'.

BTW, this device most likely renders the car unregisterable where I live.

10.B.1

a. REJECT when:
1) Bumpers are not 4.5 inches in vertical height.
2) Bumpers do not extend to the entire width of original body
wheel track.
3) Bumpers are missing, improperly attached, broken, or have
portions protruding which create a hazard.
4) Bumpers are not made from a material that is strong enough
to effectively transfer impact.

If the car were supersonic, something like that might potentially cause a shock wave to start ahead of the car and miss the rest of the body. I can see that *mayyybeeee* reducing drag. But at the extremely low subsonic speeds we drive at, I'd be shocked & stunned if it was proven to actually work.

It shows a thought process in the OP that seems to be not too far off, though. I'd believe something like that quicker than I would magnetized fuel, turbulenced intake air, 2 oz. of 'snake oil' in the gas tank, or self-generated and burned hydrogen wizardry...

It's not very "sexy"- needs to look like a front-mounted Ram Implosion wing.
