Too many other factors here to draw conclusions.
Driving mix, prevailing weather conditions, roof rack design etc etc
You can't make any direct comparisons unless you copy conditions exactly.
For instance,
The D3 has a cd of .41. But two cars with the same cd, but of different body design, will be affected differently by altering the air flow.
I live in a fairly windy part of the world (so much so that it regularly attracts events such as world flying 15 championships).
My D3 is kitted out with bullbars, wheel carriers etc and weighs around 3tn, so any extra resistance will have a different effect than for a 2tn car.
Very few things in physics follow linear relationships.
My driving is also a mix of very slow speed stop-start; 110kph hwy driving; and gravel road driving. The fuel figures I've quoted are averages.
TD5 more fuel efficient than a TDV6, who knows! I'd hazard a guess and say no if the two motors were slotted into two identical cars and compared like with like! It's a pity the TDV6 is available in the new fender in order to make a better (although not perfect) comparison.
If you want fuel efficiency, without the rear carrier, aux tank and roof rack; I was getting as low as 7.5l/100km!


.. then I put on the roof rack and went up to 12l/100km
.. then I put on the roof top tent

) with carbies and 35's AND a TF727 with a standard 85 or whatever litre tank. Maybe your extra fuel capacity is a false economy.
