Interesting. If I recall correctly, that's the same drag as my 1991 Eagle Talon has, .29 (with the headlights down) Supposedly, the Talon can hit 139 mph but I can tell ya I've had the needle buried SEVERAL times (145 mph speedometer)
As the owner of a C5, anyone wanting to test the aerodynamics of their car at night with the headlights up has a death wish.
I think most testing is probably done in the daylight!! Especially considering 180mph is about 264ft/second, and 200mph is almost 300ft/second (293.3 actual)!!
