Long production times are due engine development. As you can see M GmbH do not follow AMG's "one-engine-in-all-models" formula.

Also M get the donor parts when standard car is almost production ready - so it is natural a launch of M model is delayed.

Still - Bruhnke said in the future the maximum delay of M model launch will be 1.5 years after standard model is launched.

Regarding boring shows: yes, their shows are boring. But still - BMW AG are in the car making business, not showbusiness.

I said it before: BMW rather announce new models when getting the all the spotlight, not at auto shows when their new model will be just one of many new models shown there - with 1% press coverage.

BMW get triple attention: when announcing the car, when hosting press test drives, and when finally showing the car at auto show. This formula proves as very successful one. So why change it?
