yes sure, but that's the catch, total aero drag is frontal area (in square feet or meter) multiplied Cd

this is gives you a CdA

a tiny car with a 0.32 Cd might have less overall drag than a prius, just because the prius has more frontal area...

frontal area determins how much air will have to be pushed around the car, drag quoeficient how smooth this will go
