Nitschke said that future M engines "at the core of their architecture" would "be closer to BMW AG engines" that are optimized for M cars, instead of following in the line of unique marvels like the V10 and naturally aspirated V8.
Great, kill what made them worth a premium over the non-M cars.
Comparatively speaking, it's easy to swap over suspensions, a diff, etc. than to swap an engine.
One reason why IMHO, it's hard to justify a 1M vs. a 135i (well, at least at used-car prices).
Now all BMW is doing is turning up the boost on the "regular" engines.
Yet, that's not reflected in the price. Before you were paying for a special engine.
