There will be celebrations, special events, campaigns, merchandising, some "100 Jahre" special editions - with some nice extra trim, color and nice special celebratory badges etc. But when it comes to "Bang!" products ... no, nothing special. Enhanced version of M4 ... that's it. And there will be an exhibition item from design department.
No time & need for d.ck-measuring contest. Priorities lie elsewhere ... 2020 is coming soon ... and so are the fierce obligatory EU-standards of < CO2 95g/km - which would require lots of new PHEVs and other innovations to reduce emissions & fuel consumption.
Not to mention the development in the area of driving assistance systems & in-car electronic systems. Lots of R&D money would be required in the next years. So ...
There's absolutely no time nor there are resources available for some vanity project ... There will be a celebration but after that there is hard work, and nothing but hard work. To stay independent & competitive BMW Group has to be entirely focused & highly efficient. No time at all for la vida loca.
