Ford Mustang (1973) - .47

Remember that these are just the drag coefficients. In order to get a representative idea of the actual drag, you have to multiply by the cross sectional area. For example, even though the VW Beetle has a higher Cd than the VW bus, the bus's larger frontal area means that it will have higher total drag.
