There are now several wind tunnel facilities within Europe for testing passenger cars with and without moving ground and rotating wheel conditions (henceforth abbreviated to MVG&RW conditions). Within these facilities, the drag of a car under MVG&RW conditions is typically less than the drag of a car under stationary ground and stationary wheel conditions. This drag difference has been found to vary from a decrease of about 25 drag counts to a small drag increase according to published sources. A drag reduction of 10 to 20 drag counts is more typical, however. Copyright © 2002 Society of Automotive Engineers, Inc.
