If you're just looking for the drag coefficient, google does great. Just google for the car name and "coefficient", or maybe "drag coefficient". Someone recently posted a site that had a whole bunch of cars listed with their drag coefficients but it seemed to be mainly 1990-1995 models.

thanks your holiness bolvine :-) it says my cd is .32.soooo is that good or bad?

this has a lot of specs on cars including the drag coefficient under the dimensions and capacities tab.
My drag coefficient is .36 ( hopefully changed now). .32 is good; close to what the civics get.

.32 is what my VW has too, though I intend to improve on it slightly.

Found this on wikipedia:

Don't know how accurate it is. Seeing as how it stats that a 2008 Scion xB and 1992 McLaren F1 have identical DC's of 0.32.

You'll have to multiply frontal area by the Cd to actually calculate drag. Two cars might have the same Cd, but the one with more frontal area would have more wind drag.

They don't list the drag on pickup trucks. I tried to lookup what the beast was and it wasn't listed. I figured it wasn't much different than a new one, so I searched year 2008, and still the drag was not listed... :( I don't imagine it was all that great anyway. If they did list it it'd probably be listed as "Cinderblock with rounded corners and covered in lard"

5th result is https://gm.ca/media/vehicles/current...hure_en_CA.pdf which says .43 for the 2008 Sierra. Assuming they've actually improved it since 1998, maybe yours is .5 or so. Since style has become so much more important in the pickup segment in those 10 years, I suspect that aerodynamic drag has (at best) NOT been improved, in favor of gaudy grilles and random junk...

Actually, it maybe even decreased slightly... The 98 Sierra has perfectly flush doorhandles, I do not believe the current models do... ;) I think the biggest improvement they made recently to the trucks is their active fuel management system.
