Well, I did write 'I thought' but: I do think so. Let me explain why: I know what the MEB stands for... and it's modular. The short overhangs are typical for the ID Buzz (& Cargo) and will be preserved + the platform is... well: modular. They can add battery packs and extend the wheelbase. MEB = Modularer E-Antriebs-Baukasten and it is precisely the intention of this platform to be modular... (So not the electric car platform 'disguised' as a van as someone states but intended to be what it is).
I really suspect that it will be the wheelbase that they will lengthen and not an ugly longer overhang in the rear (like you state: "only the bed will be extended past the rear axle for the LWB version"). We'll see, I'm curious.
Of course I could be wrong (I read so many "facts" and assumptions about the ID Buzz that I may counteract or have my own, I guess) so, this is mine about the wheel base. Got two more: it's a people carrier, 5 person 'car' (there will also be a7-seater version later on, here you go, large families) more intended as a practical vehicle and a valid alternative to the suv. I guess it also aims to get people out of regular cars, minivans, offering something different as it were. It doesn't have to as big as the transporter now (there will be a new transporter later on). I have a suv now and would exchange it for an ID Buzz should I be able.
Also: the LWB cargo will be the base for the next california (second half of this decade so I will not wait for that one now and keep waiting for our ordered coast). Keep in mind that the ID Buzz (and swb cargo) is 20 cm shorter than the current swb transporter and -I think- you can allready place two euro pallets one after the other. The lwb ID Buzz cargo (& 7-seater) would have a 30 cm longer 'radstand' so wheelbase than the swb and will therefore not be much longer than the current swb t6.1 transporter.
And now do not think that I can not be critical: the price will be high, too high probably. I am not impressed with the charging time and for the width inside: I hope it is ok for the California (3 child seats can't be placed next to each other in the 5-seater they bring out now so that doesn't bode well). Also: after flattening the rear seats, you do not have a flat floor, so as a replacement for many station wagons where this prevails, it does not score. But for me it's a new interpretation of the old and forgotten large monovolumer and I'm a fan.
So, let's be happy the ID 'bulli' is here, I am.
