Vortex generators - where's the solid data for hatchback/van benefits?

Info given to me by Ron Davidson at Airtabs. (Posted with permission)
  • 3rd party tests showing utility of tractor/trailer "gap" VG application at MIRA (British Motor Industry Research Association) test track, by IRTE/BTAC (Institute of Road Transportation Engineers / Brewing Transport Advisory Committee), 1994.

  • Airtabs background info on the MIRA/IRTE/BTAC report.

AND most relevant to my situation:
  • Images showing wind tunnel results (base pressure reduction, ie. improvements to low pressure zone at the back of the car ) on a Civic hatchback model with VG's installed only on the sides. Click to zoom.
