what is it?

 

Honda for some reason never releases this number unless its low. I searched for days and days for the drag coefficent for the TL but I never found it.

Only known Honda car that they released the drag coefficent for is the Insight.

 

its .30 for the nsx and it used to be .32

 

It might not be that bad – the frontal drag is a function of frontal area, CD, and velocity squared.

I think the 97 3.0 CL was around .32 (or something like that) and there is a guy who has some “auto software” that posted a derived CD of .32-.34 for the 2001 CL. (Who knows?)

The large amount of inlet air used for engine cooling will hurt the CD, but help the car run at high speeds (at full power) in desert heat. As a note, while I like the “body kits” for the TLs, I would mention that removing air under the car could help the cd and lift, but could reduce the air flow to the tranny and – well – who knows what the possibilities are for tranny overheating under full-load, full-speed runs…

I always have a laugh when I see a low CD for a minivan (or SUV) and the folks expect to get 35 MPG on the freeway at 85 MPH
