I happened to be looking at Porsche's website the other day and noticed they publish drag coefficients for their cars. The base 911 is Cd .29, and the highest-drag variant is the GT2 RS with a giant rear wing at .35.

One thing to keep in mind: sports cars have much smaller cross-sectional area compared to full-size trucks, and their total drag is much lower. That GT2 RS works out to about 0.75 square meter, while the lowest-drag RAM, the outgoing EcoDiesel quad cab, is 1.16 square meters.

Looking back at other cars of that era, that was a darn good number.

The rear greenhouse C-pillar area reminds me of the GM EV-1 (Impact concept).
