This discussion is going on in some other threads on this forum, but hidden as it's kinda off topic in those threads. New 90D owner MarchX took delivery of his 90D and is reporting that the not only does the spoiler retract, but is speed sensitive. Here's a link to pictures of his new 90D with the spoiler retracted and extended. MarchX's 90D Post #148 Could it be that Tesla Motors is just streamlining production or perhaps they included it because of the additional 1-2% battery savings? Understandably, P90D owners might be a little hot under the collar about this, but hopefully they didn't upgrade for the spoiler alone. I have a 90D ordered and am very excited about this development.
