I think different subjects here are being conflated. Maybe I can help, if I remember this all correctly.
This is a far more complex subject that a simple article, so a brief history. The biggest thing to remember is that Porsche was a tiny, tiny niche carmaker, a tiny blip. Their primary market was the US by far, and then Germany. By the last 1970s, they realized that rear engined cars were anarchisms and the 924 and 928 were the future. The 911 was to be discontinued. Didn't happen. A US CEO came in and turned the company around. Front engine cars dead and the 911 the only car left - the ONLY model. Weideking comes in, see the world is going SUV, and using the VW SUVs, starts building Cayennes and the 4 cyl front engine car replacement, the Boxster. Sales "explode", well at least as much as they can for a company selling under 100K cars. And indeed it is true, he brought the Japanese in to teach them how to expedite manufacturing, as in JIT inventory. That's all true. This is how they used to build 356s, everything by*hand. Remember, as a niche production company of what was, and is, considered supercars for regular people, there are MANY documentaries.
That article was written in 2010, just about the time, at least for a few minutes, Porsche AG became the richest company in the world. And then it all collapsed. Some history:

But, you can thank him for your Macan. Without his foresight, you wouldn't have it. The Japanese certainly brought the original Porsche AG into modern manufacturing. But it probably would have happened anyway. Once the dust settled and VW AG owned the Porsche brand, VW AG would have done it anyway just as today they share engines and other parts between the Porsche and Audi brands. For example, the PDK in your Macan is not a ZF PDK used in the Sports Cars, but an Audi double clutch transmission that was modified.
Assembly (physically putting stuff in place) may not be done by robots, but key bolted joints such as those holding crankshaft, rods, and heads will be torqued by a machine in groups to equalize clamping forces and control torque. Most important, every part will be machined, heat treated, coated, etc by computer controlled processes. Even steelmaking, casting, rolling, inspection is automated. No human judgement permitted.
Probably true for the Cayennes and Macans. I don't think thats all true for the 911. Here a a couple of assembly videos. They are clearly doing some engine assembly by hand. Workman are using screwdrivers and nut drivers by hand. Others are using power tools. Now some of those power tools can certainly have the torque setting preset. When I was researching tools
I came across Wera, a German tool company. They sell all kinds of industrial hand torque tools with preset torques. I can see the use for them now. In fact, in one of the videos the screwdriver looks like a Wera too.
I see a LOT of hand fastening in here
Here was the 918 line. I think I read on RL someone picking up his car and it was about all hand assembled.
If you look for Macan engine assemble videos, I can't find any. They always show the production line which is mostly automated. Maybe because the engines are shared?
And a Toyota assembly line. It looks far more automated to me.
