i Think the reverse.
I think it is the next sharan. Looking at the nose, its got that mk8 people friendly bonnet design (something that a van just cant do..) - profile is the same as the current sharan but it takes some more cues from the transporter, generally speaking - maybe as some sort corporate decsion making out that transporters are more pupular than sharans - lets add some design cues!! coz everyone will love that!! (barfs a litte, knowing that he prefers the current sharan to this as a comparison..)
Just a theory. If you have something that is not doing well, you take cues from the thing that is doing well. Unfortunately, these decisions often come out with some sort of... mangled birth child. Oh dear...
Edit (five mins later). I looked at the pohtos again. The driver is obviously sat quite high up.
My.
If this is how the t7 is going to look (if the mk8 golf is anyhting to go by.. potentially...) i sheerly hope someone figure out how to retrofit adaptive cruise control to t6 *thinks about the detailed threads on the subject already..*
