Wizard, that's an incredible post, I quoted it in its entirety to praise it! Thank you for taking time to really spell things out for all of us.
One follow up question - as I read about the somewhat confused nature of this development beast, I am wondering who is in charge. Does powertrain development fall under Kuzak? I have had the impression that he had influence in selecting this direction (Ecoboost) for powertrains, but maybe I'm just misunderstanding who does what internally. The reason for asking - as an outsider, my impression of Kuzak is that he's a really good engineer who is also good at shepherding programs and people. That's why I'm curious about his level of oversight for this program.
