What annoying LITTLE things about your car make you want to punch Opel?

That's also the main reason behind the fuel burn numbers, half the revs, half the duty cycles, half the fuel ingestion/usage

...but twice the torque? something doesn't add up

My front brake disks had to be machined at 60,000km. Is this normal, Opel?!

Twice the torque is due mainly to 2 things in a turbo diesel engine, very high compression ratio - both static compression ratio and under full compression stroke with turbo boost included and the very long stroke cycle of diesel engines (very 'undersquare' bore/stroke ratio design) even n/a petrol engines with high torque will be the ones with a very long stroke or undersquare bore/stroke ratio and this is also the reason for the very low revs of diesels - the longer the stroke cycle the lesser the ability to rev high, same too for petrol engines...

Brakes/brake discs on most of our smaller 4 pot Opels are due at around 80,000km, 60,000km does sound a little premature, it could be normal or it could be for a large number or reasons...high po pads chewing the discs at a higher rate, softer material disk batch, aggressive driving and leaning on the brakes more than normal etc. etc. etc.

isnt it something crazy like 30,000 psi in the chamber?

Yep, very high numbers, even more than that on industrial mega sized diesel engines which only rev to say 1,200rpm, eg: the supersized shipping diesel powerplants...

Torque output from TD's is not magic, there's a simple science behind it and there's a purpose for them...they're still not there for the ultimate in sports car applications (no matter what the torque numbers, the hi po petrol units with the ability to rev freely are still quicker) but they are getting better

They are still the top choice for work horse vehicles, where you need the stump pulling power, but don't need to get anywhere in a rush and are a good choice for an everyday vehicle for fuel running cost savings, although o/a running costs may end up being the same in the end...
