I have a small sedan, with seats that fold down; not exactly a hatch, but close. I have a Saris Thelma rack and it's fine. I didn't put it on this year, been shoving my bike in the back, but it never interfered with anything. The Thelma is for 2 bikes and is super easy to use. I had a similar one bike rack (same type of latching principle), but my car got rear ended and the rack got trashed. At that time, Saris did not make a one bike rack and they (Sears) had stopped making the one I had.
