Modern funny cars travel almost
340 MPH in 1000 feet from a standing start.
This Napa car, and many others, have little diverters or aero fences on the leading edge of their steering tire wheel wheels. Presumably to make the air jump across the wheel well opening.
Also notice the very large radii at the trailing edge of the wheel well opening.
I'm curious as to how a similar leading edge fence would do on my big truck, only doing 55-70 MPH. I always planned on trying VGs in this location.
