Hmm, you need to understand the complexity of the situation. Quatar are poised to take the VW options that are causing paper losses for Porsche. Remember that Porsche was also briefly the richest company in the world due to these options. Losses are not real, just as the profits that made it the biggest company in the world were not real. The reality remains that Porsche is one of the most profitable companies in the world. Porsche was set to take control of VAG, not the other way round.
In reality, Porsche is a profitable business, and VAG isn't. Quatar will remove the equation and Porsche will remain as a very profitable business and VAG a large company losing money. VAG will be bigger, and Porsche making more money. Wiedeking probably had ideas above his post in hindsite, but taking over VW was a possibility. If it worked. he would have gone down as the worlds best businessman.
I know the complexity of the situation, and Quatar hasn't confirmed anything.
In reality Porsche has a lot of debt and will likely be absorbed into VW.
Both VW and Porsche said no F1.
