I have said that Bangle's job is secure with BMW because to fire him would be an admission that the car designs have been poorly recieved at best. That the time for him to go would be in about four or five years with a new design team in place and with his current contribution lessened , and no doubt about that.
However, if he voluntarily quits because he can no longer stand the heat, that would hurt BMW and it wouldn't surprise me if he did that and that he didn't care how much damage he did to BMW in doing so. His personality is sort of arrogant if you recall his explaination of the 745 design a couple of years ago.
He may find it difficult to get a top job with another auto manufacturer under these circumstances, so, I think he would wait to quit and BMW would not fire him, so I think he'll stay for a while longer. On the other hand,I doubt he could get another top job with another car company and that cancels out the wait to quit thought so it could be true.
Good bye Chris, God's speed and never darken my door again.
