As part of the global launch for the i8, BMW has set up a wiki page for the i8 in Germany. No particularly new news, but it does consolidate a lot of info in one place, including the ability to zoom in on the exterior or interior of the car. I was hoping to spot the Display Key in the slot above the gear shift, but alas, it wasn't there.
Anyway, here is the link. Turn on Google Translate to get the text in English.
