I believe that Hucho mentions,that without a reattachment surface,VG efficacy in three-dimensional flow remains unknown.

Stumbled on this PDF last night,
Don't know much about it, but did get that point, you need to have a surface to reattach to in vehicle applications, so suitable for sedans, but of questionable value on wagons and Kammbacks.
As they do add drag, you need to make sure they are properly suited to the application for a gain.
