Possible Correction: a Sept 1981 article by Jim Dunne in Popular Science magazine titled 'Low Drag Cars' lists the Chrysler Imperial of that year as having a Aerodynamic Cd of 0.41 pretty good... considering that the Porsche 924 of that year was 0.34 and a Corvette 0.45 The Eldorado of 1981 is listed as a whopping 0.55
sample quote "Interesting to note the aerodynamics on the 1981 Imperial was so good for its era that some NASCAR teams used the Imperial as race cars."
