I have recently read an article on Mercedes-Benz modelling a car on a animal called the Box Fish. This fish has a remarkable ability to swim in very turbulent currents. Mercedes-Benz then took the basic shape of a Box Fish and built a car which then has a Cd of 0.19 which is very impressive for such a boxy looking vehicle.
I thought I would give this a try on the model on Veloci-velo with startling results.
The previous best cDA figure I achieved was 0.081
Re-modelled "Box Fish" shape cDA= 0.027 !!!
I could not believe it so I ran three separate tests and all tests came back with the same result!
This is quite a reduction in drag and would make Veloci-Velo and very fast velomobile.
I am conducting more tests and calibrating with objects of known Cd factors, More to come on this!
