Interesting chat with BMW i and M design boss Domagoj Dukec at the preview for the new BMW i8 Roadster last night.

He said the i8 was a car for a moment in time, and not always one that had to be in the BMW range being replaced for generation after generation. To that end, he compared it to the BMW M1: “It worked at the time, but why do it more than once?”
