Thanks for the new term, I've been calling it aero density in my head (although I've been factoring in CD as well as frontal area)
Cars with poor 'aero density' are no fun to hypermile.
I actually prefer driving my Renault with the trailer attached. My CD goes from 0.33 to 0.45, but my weight goes up by 500kg. Although high speed glides are reduced, low speed (where I spend all my time) glides are improved. Sadly, it's still less efficient with the trailer.
