The only exception is when jumping the car. Then it's okay to leave the track, but you must still maintain at least two wheel "over" the prepared surface, even if they're not actually touching the track.
For example, check out my turn 4 in this lap: http://www.seccs.org/gallery/Car%20P...2_1-13-393.wmv
That's about as close as you can cut it.

You know, I'm going to guess that for the smallest fraction of a moment, you had 3 wheels on the grass...right before you reached the rumble strip.
