I always thought Cd for a 900 was pretty low... 0.34. but that is pretty high for modern aerodynamic cars... a viggen is 0.31... a 9-5 is 0.29 (.30 for the sportcombi)... a 9-3ss is 0.28 (but 0.33 for the sportcombi)... a Porsche 911 is around 0.32. and lots of normal + fast cars (Ferarris, Aston Martin) have Cd >0.34... of course drag in a "fast car" is designed in appropriately to improve traction (not so much the case for a Toyota)...
of course frontal area comes into play also... I don't think it is quite as simple to multiply the c900 Cd by frontal area (like one might for a new Civic) because the car is shaped aerodynamically in 2 planes not just in profile (as is the trend these days)...
I think aerodynamics might be less of an issue than engine/gearbox capability, but I could be wrong...
btw, Ryan left a contact email address with his post, so if he doesn't return, one could probably ask him the particulars (or to look back at this thread)... very cool stuff...
