Hey everyone, I've been lurking on this site since 07, finally decided to get registered.
Anyway Ive been thinking of how to reduce the turbulence (and thus the size of the wake) behind the rear glass that occurs on most sedans.
I conjured an idea that would reduce the total size of the vehicle's wake to trunk height whilst allowing the driver a clear view out the rear window.
Here my idea is shown on a B8 A4.
To allow full operation of the vehicle's trunk, these strakes would be mounted to the roof with small hinges, and the trunk would be equipped with guides the strakes could freely slide in.
Any input is welcomed. I think this could be potentially easy to build, but would it pay off?
