What about spoilers for hatchbacks? I've noticed a few types:
- Type 1 - placed below the rear window

- Type 2 - above the window, extending above the roofline with a gap under it

- Type 3 - above the window, extending the roof horizontally of slightly down

- Type 4 - above the window, tiny

Here is a Honda with two spoilers, types 1 and 3

Which of these will help or hurt FE? I can tell that type 2 probably produces drag, but what about type 1? Does the tiny type 4 do anything?
