Sometimes we Krauts live up to our hard-headed reputations.
Long, long ago, in a galaxy not too far away, Porsche made a 1300 CC 356 engine with roller bearing main bearings. Great little motor.....until you "lugged" it one time and Kaput! the roller bearings self destructed within short order. For those who don't understand the term "lugged" it is what happens when you drop the RPM too low in gear and then try to accelerate away. It's a nasty sound and a really nasty vibration that does terrible things to your crankshaft, bearings, connecting rods and pistons.
In any case, Porsche went back to plain main bearings and the problem went away with the change. So..................can someone explain why Porsche would put more roller or ball bearings inside the engine????
The only explanation I can come up with is the distance the intermediate shaft is from other pressure lubed rotating shafts and they are saving the porting/runners/tubing to get pressure oil to it?
