As a thirty-year plus Porschephile, I've been following this but haven't been successful in finding authoritative information. However, for some context:
[All off the top of my head without fact checking]
The Piechs are the other half of the Porsche family (I'm talking people now, not cars or companies). I think the Piechs were Ferry Porsche's wife's family. Back in the 1960s the third generation of the Porsche family started working at the company. "Butzi" Porsche did the exterior design work on the 904. Ferdinand Piech ran the racing department from about 1965 to around 1971 (think 906, 910, 907, 908, and 917). There was quite a power struggle between the Porsche side and the Piech side. For example, Piech seemed to be in maybe too much of a hurry to replace the 904, designed by Butzi, with Piech's own 906. Eventually, the power struggle became a threat to the success of the company, and even its' survival. Ferry Porsche led an agreement that forced ALL family members to retire from direct management positions with Porsche. Ferry retired as president but remained chairman. Butzi started his own design firm. Piech went to work at Audi, eventually becoming CEO and chairman of Volkswagen Audi Group (VAG).
I think Ernst Fuhrman was the first non-family president. He ended the 917 program and focused Porsche's racing on developing the 911, creating the 911 RSR. I think he was still president into the 935 era. Fuhrman also predicted the end of the 911 and initiated the 928 as its' replacement. But how much of each of those was Fuhrman's decision and how much was the families' influence I don't know.
The Porsche and Piech families have always had huge personal holdings in the german auto industry. Ferdinand Sr. received huge amounts of Volkswagen stock for designing the Beetle and its' factory. Obviously the family retained huge amounts of Porsche stock. Neither VAG nor Porsche ever owned the other's stock. But the two familes have always had considerable influence on VW and outright control of Porsche. Porsche did a lot of engineering work for VW (recall that Porsche makes twice as much money as an engineering firm than it makes building cars). The 914 was a Porsche-designed replacement for the Karman Ghia, and VW sold Porsche bare chassis for Porsche to build the 914/6. The 924 was a Porsche-engineered replacement for the 914 that VAG cancelled. So Porsche bought the rights and built it, well, it was built by VW for Porsche using an Audi engine. Audi (VAG) built the 944 using a Porsche-built engine. (The 968 was built entirely by Porsche). In the 1990s Porsche built one of the Audi RS cars. VAG used to call their dual-clutch semi-manual a "Tiptronic" which is a Porsche trademark. The Toureg and Cayenne we all know are shared platforms. I have a personal theory (with nothing to back it up) that the hugely successful Audi R8 and R10 race cars are Porsche engineered. Point being, the two companies have never been directly linked but have always been very closely intertwined.
Anyway, I wonder how much of the inter-family power struggle continues to this day. Ferdinand Piech has huuuge holdings of VAG stock, and I think he's the largest individual owner of Porsche stock. I think the reason Porsche dropped out of European prototype racing (what became the Carrera GT) was Piech's decision to not compete with the Audi R8/R10. (I really want to know how much commonality there is between the R8 and the Carera GT). I think that is a reflection of the reality that, while VAG and Porsche are (were?) independent, they were influenced at the top in a synergistic way. In other words, neither company was going to do something that would have a negative influence on the other.
But Porsche's move recently to try to gain control of VAG, hmmm... Was this perhaps more inter-family rivalry? The Porsche side impinging on Piech's VAG empire? And is the current counter-move Piech giving tit-for-tat? Is Piech trying to pull Porsche back into his personal fiefdom? These are the things that make you go "hmmmmm..."
