The 5-speed Insight had an ULEV rating, even with lean burn: ULEV = "emits 50% less polluting emissions than the average for new cars released in that model year."

So I have to wonder if it was eliminated more for driveability/consumer acceptance reasons.
I assume the ULEV rating is during standardized tests that may not hit the very specific requirements to engage lean burn. I haven't seen any testing, but I have to assume NOx emissions are high when it's engaged and this a likely reason it was killed.

However, these are only assumptions.

For comparison, Honda did put this drag-reducing spoiler on its 2001 Civic sedan. Most OEM drag-reducing spoilers on high-MPG cars are flush mounted, and fairly subtle, like this one is:
Subtle indeed. I don't think I've ever noticed one on an actual car.

I figure there is a chance that the spoiler could be near the right height to reattach airflow, but I doubt it. No chance for any thorough testing, but I won't miss it either way. It was kinda ugly, and I much prefer the clean look it has now.

Upcoming plans: lowering it an inch or so and full moon discs.
