Hello.
Does anyone know the drag coeff (or CD) of Honda jazz? I need this parameter because I have a gadget [www.myscantool.com] that through
obd2 and it counts cars performance.
Thank you guys.

 

In all the Fit previews/news/reviews and other countries' honda websites that I've looked at I've never found that info either-- has any Jazz owner read a non-US auto mag review that listed the Cd?

 

I googled high and low, and didn't find squat for Fit or Jazz. Would estimate the Fit to be 0.33 to 0.40 from what I saw on other cars when googling -- but that's a WAG... (wild a** guess)

 

0.33 is probably to low IMHO, as the 1988-1991 CRX HF was at 0.29, while the Si version was at 0.30. The only other car I know of in the 0.29 was the Lexus LS400 when they first came out, and that was because the did extensive under body work to acheive that. My guess is close to 0.40, as I think that 0.50 would be like a 45 degree angle where 1.0 is a straight horizontal surface (although my guess could be totally wrong.

 

I found an entry on the Edmunds Toyota Matrix discussion board which lists the Matrix Cd as 0.321. I don't know what the cooling drag of the two cars is like, but as the body shapes are so similar, I would expect the form drag to be very similar. The body of the Fit has fewer transitions and protrusions than the Matrix, but you should be able to use 0.33 as a value for comparison.

 

The Matrix is 3.7 inches wider, 1.6 inches taller, and 13.9 inches longer. If the Matrix is 0.321, the Fit could be lower than that. And even it looks like the Fit's frontend is more ideally sloped too.

nice comp man

Excellent points (Thanks for the pictures).

 

Honda is no longer posting Cd figures, but I wish they would...
