But if you’re trying to convince me that there isn’t a clear DNA link between the Beatle & the 356 or (more to my point) Volkswagen & Porsche, the case kind of gets murky when you see the clear link that still exists to this day between the two and even Audi. While not as strong as some collaborations it’s there none the less.
A great example of this continued interaction today are the Porsche Cayenne & V-Dub Touareq are basically the same platform and about 60-70% of the Cayenne’s parts are shared with it’s lesser Volkswagen sibling.
Oh no, not trying to say there isn't a clear DNA link at all. Very definite DNA link. In fact one thing that VW, Audi, Daimler-Benz, Auto Union and a few other manufacturers that didn't survive WWII have in Common is Porsche.
Your right that in many ways you could consider the VW/Audi/Porsche Group to really be one large company. Until recently, they each had their own specific range to cover. VW was still the economy car, Audi was the luxury and near luxury segment and Porsche was the high end Sports cars. Those lines have begun to blur recently.
The ties that extend back to pre-WWII also explain the ease of engineering swapping that has gone on between Porsche and Mercedes-Benz. Before Daimler AG bought AMG to turn it into an 'in-house' Mercedes-Benz tuning firm (like BMW's "M" brand), they used to turn to Porsche to help engineer their higher performance cars and when Porsche needed a automatic transmission for the 928, they turned to Mercedes-Benz.
I can't recall much collaboration on those levels with the big three American manufacturers. Although they each tried to do everything while the German manufacturers were all fairly specialized.
Porsche has also been trying to replace the 911 for decades but the fan/customer base won't allow it. They've made many superior cars (like the 928) but the 911 community bashes anything else so hard that it hurts sales on the other cars and increses sales of the 911 evolutions. The current 911/Cayman/Boxster issues are a good example.
