Hi Dave,
Yes, that is right. The oblique view from above gives a clear view of the swirling air flow at a seated head position.
As it is a model, they may not have matched the Reynold's number to that of of a full sized vehicle. But what is shown in the model wind flow seems to me to be similar to what the air pattern would be based on what I was hearing when I was in the new beetle.
Is this a case where the automotive speed range makes a big difference in the air flow? Is it the unique shape of the beetle that causes this? Does the Cd change with speed dramatically in the beetle?
