BMW M CEO
As BMWBLOG explains:
"At the 2015 Frankfurt Auto Show, we sat down with Franciscus van Meel, BMW M CEO, to talk about the future of the M brand, including all-wheel drive M cars, manual transmission, electric drive M cars and much more."
For the brief electric drive discussion, skip forward to the 5:20-mark in the video, at which point van Meel says that the future of M definitely is electrified, but adds in that he's not sure at what time it will come.
The concern, it seems, is additional weight.
