I was looking through some old files and found this scan.
This was published by Harry Bradley in IIRC VW Trends in 1981. It's basically a Beetle with a Baja hood and stock (but narrowed?) fenders, with flushed side glass.
With modern cars like the Aston-Martin Valkyrie, there is an upper envelope with massive ventilation in the wheelwells. This design could be extended by enlarging the mesh area to cover the entire front and rear quarters.
