While the spoiler may not appeal to you, in the
case of Prius it has a very real function to cleanse
the air flow in the rear of the vehicle.<br>I've
stated in earlier postings to this club, I was very
surprised to learn over a year ago that the chief engineer
had decided to add the spoiler. We demanded alot of
rationale to justify the action. It does reduce the
coefficient of drag CD to .29 which is slippier than our
Celica. But what it delivers in a tangible sense is an
additional 2-3 mpgs on the highway test. So it has function
as opposed to being ornamental. PM
