For those saying not even possible, Scion has already confirmed it for projection year of 2017. They are just using the im as an additional vehicle, though both are based off the same chasis. My question is: is one version the hatchback and the other the sedan? (Think Subaru mentality)

As for that mark X, that's a goreous vehicle but I would see that more as a lexus market vehicle here in the US.
