you may want to have a look at (what toyota calls) 'aero corners'

they have recently appeared on a lot of aerodynamics cars like the new prius, iq, citroen ds3, and some others.

basically the corners before the wheels are squared off, sometimes by agresively styled daytime light, what looks like air scoops or just add-on like bumps in case of the IQ.

but all designs seem to create a sharper corner and a more flush pannel leading up to the wheels.

this aero corner thing seems fairly new and appart from a general description i don't have much info on it, but the fact it's on cars like the prius sugests there's something good about the design.

it may also explain why some olders cars managed to get a very good Cd with relatively square fronts... perhaps 'making the front as smooth as possible' is not always the best strategy
