Hey fellas. I've had my S for just over a year now, and I think I know the vast majority of statistics regarding the car but two that I have not been able to find are the coefficients of lift and drag. Any number junkies out there that can help?

 

I'm not sure about lift. But I heard the number .30 thrown out for the drag coefficient.

Its well known the S2000 isn't very aerodynamic.

 

The faux brake vents and convertible top definitely don't help the drag coefficient. But I'm not complaining =].

 

i remember reading from somewhere (http://www.nsxfiles.com/ ?!)that a stock S2K create 88lb of lift at the tail at speed.

to me, i think a single outlet exhaust with the stock rear bumper would have even more lift cause both flat mufflers are gone (which should smooth out the air flow to a certain extend). ( and i think spoon AP1 racer solve the problem by putting grill opening at the rear bumper to let air out )

i think the big opening in the front bumper and the upright wind shield really hurt the drag coefficient. but both seems to be important. the big opening is good for cooling (since F20C runs hot) and the upright wind shield provides more structural benefit in roll over protection.

my $0.02 on this

 

These are not official numbers but general consensus is that the s2k Cd is 0.38 top up and 0.42 top down.
Frontal area is fairly small so the car doesn't suffer too much on top-end acceleration...
