Vortex generators at rears?
So I’ve noticed a trend on a lot of modern cars using vortex generators at the rear of cars? Why is that? From my understanding, it detaches air flow and creates vortices that can reattach to other parts of the car, like a large wing on the back, or near side mirrors. So why the very rear?
The newest Hyundai Sonata uses them at the tips of its mini box cavity rear spoiler thing, the newest Elantra has a few on the sides towards the back past the rear windows, and many other cars have them on the side of the rear tail lights.
Can someone explain this?
