That is a beautiful car that I wish we had here, although it is far too new for me to consider. How often do you use the cargo carrier? Would it be possible to use a tow hitch-mounted cargo box instead? I am not sure how well that would work with your hatch, but that would fill the wake, instead of increasing drag.
Also, I am sure the guys here would say the cargo box would be more aerodynamic the other way.
Has anyone boat-tailed a cargo box?
