a lot of cars these days are comming out with hood rides that seem intended to guide the air past the A pillars.
this can be partly explained by styling trends and might not have much to to with aerodynamics, but on the other hand the A pillar is a bit of an aerodynamic hotspot, so it's not unthinkable at least some research and improvement has been made regarding the airflow in this area.
it just struck me that with a little imagination some of these designs begin to resemble some 30's to 40's era car designs
it all reminds me a bit of this
perhaps, designs that treat the wheel arches and hood as separate volumes might have certain aero advantages without actually looking retro
