I wonder if the Cd figures that are published are accurate with the stock wheels.

It seems as though there would be a lot of turbulence within the wheels.

The Lexus LS460 also has huge open spoked wheels as well, yet has a .25 Cd.

I remember reading that some of GMs' Cd figures were given with the rear view mirrorS removed, and other tricks to bring the Cd down.
