For a vehicle of that age that co-efficient of drag is VERY IMPRESSIVE!
Funny that back then you know they weren't wind-tunnel testing (at least.... I don't think so?)
If only it weighed 2000lbs less... cars back in those days were verrrry heavy and made no power almost it seems.
Either way, the concept alone of that kind of aerodynamic efficiency for that day and age, VERY cool!
Thanks for sharing
