I removed them last spring in the first stages of the weight-reduction kick; all told, the pans were ~10 lbs. I might do something lightweight in the future.

Yep, and the 3rd gen continued that with a slightly modified design:



The Insight doesn't have the raised diffuser like the Prius, so it's just a flat surface without the inside shaping like the Prius:



But I think the splitter should function the same, adding surface area for the airflow behind the tire to attach to. I inset it like on the Insight rather than making it flush with the outside of the bumper cover since there's probably a reason the engineers did that despite having all that real estate available.
