This merger is as much about long term survival as it is leveraging a larger size to contain future costs. I don't believe Tavares who will be CEO and has spent much time here in the states will fiddle too much with things here. NA makes all the money, and with some fresh things for Dodge and Chrysler could make even more. This new company's biggest hurdles are in Europe and China, not here.
"PSA's group net profit increased 13.2% to a record 3.2 billion euros, and the company increased its dividend against 2019 results to 1.23 euros per share, up 58% from 2018 levels."Folks need to wrap their minds around what you said. There's no reason for Chrysler and Dodge to do anything other than expand lineup, within reason.
FCA "reported full-year net profit from continuing operations of €2.7 billion, or $2.96 billion"
PSA makes money in Europe, it made more money than FCA last year. It is supplying the platforms and capacity that will save Stellantis. You can discount money losing Fiat operations all you want, but the merger doesn't work without PSA.
