This would an area of weakest available data.And I wish these teams would test for 'real' cars and publish the data.
The 1957 MG EX 181 is of the few cars with 'real' cars measured.With it's limited wheel fairings it was reported at Cd 0.12.

You can see what happens to the VW flow body when wheels are added.Although fairings would bring that Cd 0.14 down.
