Their Cd now isn't much below that of my car. Actually it might be fairly close now as I've made a few aero improvements to my car since I did the coast down tests that netted the 0.17 Cd figure.
I wonder if those front wheel driveshafts are rotating on the outside or if they are a non-rotating tube with a rotating shaft inside. If the latter, then you could mount fairings on the round tube to get some additional drag reduction. If the former, I wonder if it would be prone to catching and winding grass around it you drove across a field of tall grass.
