Coefficient of drag
Anybody know what it is for the R231 models, or have actual drag-limited top speeds?

Don't know about the facelift model but the original SL R231 has a Cd value of 0.27.
The drag-limited top speed will be well above it's capable top speed (engine/gearing), so not a factor on the car

Thank you for the info. By drag limited, I meant combined engine & Cd. Gearing is certainly not a problem, as it would allow 250mph at redline in 7th.
