TBH, you don't really need to. Never thought I would hear myself say that.
Yeah maybe that's Fords engine research "view" but I'm pretty confident Audi are not gambling that it can handle the power. I found a document some while back written by a couple of the engineers who designed the BiTdi and it has a bunch of significant engineering changes compared to the regular V6 3.0 Tdi. They significantly changed the cooling of the head - split water jacket and improved oil splash / spray and also stronger pistons.
Having said that the pistons are still aluminium which Audi say are good for up to 80Kw per litre... the BiTdi is not far short of that.
So I disagree that the BiTdi is beyond what a diesel can be pushed to safely BUT I do agree that trying to push it further without more engineering changes might not be a good idea.
And as you state... it really is pretty much all the power you need on the roads that we have with the traffic volumes we have. Any overtake where I thought "if I had more power I would have gone for that", well in reality I probably should not have even considered it 'cos there is too much traffic about.
