Neulich gab es in "Corvette Fever" einen lesenswerten Artikel:
Alle Corvette-Generationen (C1-C6) im Windkanal (leer, mit Fahrer/Beifahrer und -interessant- bei C2-C5 zusätzlich mit aufgeklappten Scheinwerfern)
Es zeigt sich ganz gut die bekannte Auftriebsneigung der stock-C2; diesbezüglich deutlich verbesserte Aerodynamik gab es erst ab der C4.

Hier die Übersichtstabelle und die Erläuterung einiger Maßeinheiten:
"Know Your Codes
In the chart, we listed both CD and CDA, and unless you're a professional aerodynamicist or just really good at Jeopardy-type trivia, the difference is probably a bit confusing. CD stands for "coefficient of drag" and is a measurement of how much drag a particular shape produces regardless of size. CDA stands for "coefficient of drag area," and is simply the CD multiplied by the frontal area of the vehicle. Theoretically, a C6 Corvette and a Matchbox-sized scale replica should have the same CD. CDA is a better real-world number because size does come into play when we are talking about drag in terms of how much horsepower is required to reach 100 mph. So even though one car may have a slightly worse CD than another, it can actually be more aerodynamically efficient if it's smaller and has a better CDA."
Viel Spaß bei der Lektüre
