Hi Axle - missed your post - will reply in , a minute.
Dennis unfortunately we can no longer count mixed bag now with some like v8 cruisers with wide flat and high torque, but rule now seems to be more smaller diesels with turbo's that dont really cut in till > 1500 rpm and are woeful below that.
I often reccomend the 4800's but only on good technical grounds.
below are torque figures for various Patrols that show that petrols do have torque up higher but their is so much more that they better diesels down to idle.
PATROL TORQUE
3.0 Td 1000RPM 275nm 2000RPM 354nm (max) 3500RPM 250nm (Peaky curve which stops @ 3500 rpm)
manual version CRD peaks @ 380nm from year 2006
4.2TD 1000RPM 325nm 2000RPM 330nm (max) 4000RPM 320nm (nearly flat all the way)
4.8lt 1000RPM 360nm 3600RPM 420nm (max) 5000RPM 350nm (relatively smooth curve)
from 2006 onwards 5% lower -> 343/1000rpm 400max/3600rpm 333/5000

Hi Axle -
Intersting example you used as depreciation costs are the reeason why independant reviews have made the turbo 100's the worst value in RACV type comparo's.
The 4800's fuel use is about 10% worse than your V8 100 series petrol , but with the patrol I had the choice of a manual which then made it better particularly around town where constant use of torque converters is really felt.
Another comparo on pet/diesels recently gave costs as $75,000 / $77,000 over some years in favour of diesel , but from these figures its much the same.
The bottom line I often give to people is that the old adages have changed and there is little real overall difference, however paying extra every week at the pump is hard for some to do.
