I find the idea of the "strap to the hatchback/trunk" boat tail even more cunning. I have a bicycle carrier that could be repurposed...
Yes, providing a full boat tail starting half way down the rear glass would be preferable... But then the trunk may not be accessible.
By end of October I will have my very first garage (with house attached
). And as you all probably know the pacific NW is probably the best place in the lower 48 for extended indoor winter month projects.
Will revisit this possibility when I have room to tinker.
2 mpg... I think that this could be worth the effort. Especially considering the aero results from Blue07CivicEX.
