1er / 2er future models: Scott26 reports; part 2

[Matt530i]

Birdie says "Y-series" & "B-series" & "H-series" are the front-runners.

Why would BMW consider B-series as a front runner when MB has the B-class?

Why would BMW consider B-series as a front runner when MB has the B-class?

I have no idea.

I guess H-series has something to do with hydrogen (eg. H3, H5, H7 etc)., while absolutely no clue about "Y" & "B". Has "B" perhaps something to do with Alpina (B3, B5, B6, B7)?

Y-series sounds very futuristic (Y2, Y3, Y4, Y5, Y6, Y7). Another extraterrestrial cross-over perhaps?


PS: MB also has M-class.
