A new paint scheme, but otherwise the body is identical; Production version now pushed to 2022 (from initial 2020), which would probably be a record, given the first Micro Bus concept appeared in 2001. Just 21 years form concept to production; Or, in other words: The concept would nearly qualify as vintage car by the time they will finally make it....
I like the ID mini van concept. Problem is this is VW...they've been talking about this since 2016...it doesn't release till 2020. When it does come, it'll be watered down to irrelevance; the EV market have leapfrogged (Moores law) for range and efficiency; so they'll have dated technology and looks. And VW loves to overprice their products....
If they released this thing this year, and it was relatively competitive for range, efficiency and price - and looked like the concept - it'd be a winner for sure (same way the original Beetle reboot was). But that won't happen for the above reasons.
