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

Don't recall ever seeing any or an announcer making comment on them, and you know how NASCAR and NHRA guys like to talk.

If they did any good they would be used in race applications.

here is a pretty serious AI race car that uses the vortex generators

Also has some other fun little aereo tricks, vents on the fenders etc... lost of weight savings. Cool car and dear to the heart since one of my cars is a v8 mustang

Also, if anybody's got coastdown or cruise-control experimental data from VGs at the trailing edge of a hatchback, I'm interested.

Interesting car, but the aerodynamic work is not designed for drag reduction. The rear wing, the VGs, the fender scoops and the wider hood are all adding drag. With the kind of power that beast is making, aero stability is king in simply keeping it on the road, and drag reduction is most decidedly not a priority. There appears to be no underbody or diffuser work at all, and the VGs probably do nothing as the wing is way up out of the rear end turbulence.

What sort of racing does the car do? Top speed stuff like NASCAR? I'm curious.
