Drag coefficients are cool *pics*
Lots of variables but always fun to look at.

a is the area of the 'face'(essentially the plane that meets the air)
cd is the drag coefficient and then the draf coeff. time the frontal area gives you a good number to compare between cars due to different classes of cars being shaped very differently(crossover/SUV versus hypercar for example)

so which number is the number you'd use to rank them by? the drag coefficient or the CD x area?
also, lower is better, rite?

my car has a lower drag coefficient than all of them hah

I want to hang out with all the boys ;)

I'd like to see the Subaru XT and the Ford EXP on this.
