Similarly to the gravity, which was wildly different from the proto! As @hydbob says though, I think it is a sapphire due to the prominent lip spoiler easily seen.
I think that middle one is a 2-door Coupe (doubt that we'll see it any time soon).
Notice the bulge above the trunk - it's very pronounced and doesn't exist on the Air. Definitely not a Sapphire.
It's also noticeably shorter and has a more sloped C-pillar.
