Upcoming projects for me, add adjustment to grill block, and wheel skirts.

*The volume of the wheelhouse affects drag.The absolute minimum has an advantage.
*If the wheels are exposed,they should be flush with the sides of the vehicle and have the convex,full-coverage covers.
*The rear face of the housing would be radiused and blended into the fender.
*I have no data on 'air-curtains.'

*If the wheels are inset a bit,then skirts can be added which will not aggravate frontal area.
*Full-coverage wheel covers are still a benefit,as they reduce windage losses of the rotating wheels.
*Ford,with their 1984 Probe-IV concept car,had something like an inner ABS fender which contacted an elastic polyurethane spat,which would deform to allow for wheel flop.Ford claimed a 9% drag reduction for the system.

*Some automakers have chosen to integrate engine cooling system air extractors into the belly pan centerline and abandon the front wheel houses as a passage for this airflow.A move which simplifies front skirts.

*The articulated front skirts on AeroCivic are a proven,off-the-shelf design which incorporates the best of everything,minus the exotic materials and exotic fabrication requirements.And basjoos has some delicious numbers to go along with them!
