KIA Rio Aero

This eco modding has made me thinking what if ...
one would take a new car with good fuel efficiency and optimize the aerodynamics without going crazy.

I picked the Kia Rio and changed its rear end dramatically, still only 1.07m longer, but without changing any of its mechanics, although a narrower wheel width in the rear would be much better, now the width has to increase to include the wheels in the aerodynamic shape.
Of course the bottom of the whole vehicle is sheeted smooth.

The results can be seen below and once more in a little youtube movie of the 3d kia rio aero.

What would I stil improve :
- increase the length still more, for smoother aerodynamic exit.
- decrease the rear witdh directly aft of the driver seat by decreasing the width of the rear wheels
- mod the front, closing the openings, leaving only openings in the shape of Naca ducts which can be  opened and closed.
- mod the shape of the front a bit.
- change to electric drive.

enjoy, maybe an extremer version will follow

Eco modding

Eco Modding,

Cars are like bricks which we drag at high speed through the air, petrol must be very cheap for us to waste it like this.

In Mostly The United States, people are experimenting with streamlining their cars, some modifications are very rough while others seem pretty good.
I know that this is not allowed in many other countries (including my own ;-((( ) by the authorities, they use safety as an excuse to protect the large car companies.

The Areo civic:

95mpg at 65mph ( 2.475 L/100km, 40.3 km/l; at 105km/h) amazing figures.
Streamlined rear-end wher much of the resistance is generated, also the underside was covered with smooth plating, wheel covers. The rest of the aerodynamic modding was limited.

The Avion 100mpg plus
100mpg (2.35l/100km, 43km/l)
Totally re-energineered "slippery" car

 The Dolphin by Dave Cloud,

?? 214mpg; 1.991 L/100km; 91 km/L
For me the best example of what can be done when you throw all conventions into the wind.
It is old news and finding a good website with details is impossible, but on ECOMODDER.COM there still is a lot of information about this car.
A lot of pictures are available on this picassweb link.
And on this picasaweb album about measurements of the dolphin for a new car/trike.
