The vehicle I was comparing my diesel landy with is the new patrol, my petrol 4wd, which when towing say a 3t van, is compatible if not better fuel wise than a diesel 200 series, do some research and you will be surprised.

For sure, there is a move away from diesel to petrol/ev particularly in Europe - but while large cargo carriers like semis and B doubles stay with diesel in places like Australia and China, then diesel will still remain the main fuel available overall.

What sort of fuel economy are we talking. The patrol owner I was chatting to a while back said he was returning ~35L/100 towing his big caravan (the patrol being a V8 petrol).

20-25l tops, that's towing 3.5t van, series 3 and 4 y62 patrol which has vvet. Mine currently returns 13L average with all general driving, 11L on the highway, 15L towing the camper with tinny on top, none of that sitting 10kph below the limit either like the 200 guys do

20-25 is a big range. I'm guessing 25L/100.... which is about right I would imagine for any modern petrol engine. The modern diesels seem to be returning ~ 15L/100 under similar conditions (unless you compare to the most inefficient deisels ... eg: the V8 cruiser diesel).

I'm not bagging the petrol, I'd rather a V8 petrol anyday myself. But while they use 30->50% more fuel than a diesel they will still be around.

I'm always amused us petrol owners always claim the best possible fuel economy. Its like the Range Rover Classic owners claiming they can get 14-16L/100 out of there classics. This maybe possible on a gentle highway run... not towing. I have NEVER done this sort of driving .... ever ... in the 5years I've probably been running one. its either lots of cold starts around town, offroad work .... or towing big chunky things along they highway. I'm guessing I average 30L/100 around town and much more towing on the highway. A diesel doing the same work would be half of that ( the cold starts don't effect diesels economy much, and when they are working hard, they don't drink like a drunk ).

If you do a lot of highway cruising not towing without the cold starts. The modern petrol motors can return great fuel economy ... This certainly doesn't match my use though

Not many,if any modern diesels will do 15l/100km pulling 3.5T, on the speed limit.

Thats definitely a pipe dream.

Yep, I have towed 3.0 tonnes once with the Hilux - one of our larger trailer mounted gensets. At 80kph (max allowed by work for these loads) I glanced once or twice at the fuel usage - around 22 IIRC. . At 100 if you were silly enough it would be quite a bit more.

Our Defender did 11.5 towing about 2 tonnes Sydney-Brisbane recently.
