P400 and towing

On a trip thru the outback ..if there is such a thing anymore..we travelled coincidently with two retirees in a tiny Suzuki 4x4 with a fuel tank the size of a beer barrel...including crossing the Simmo with a couple jerry cans in the back.

They had no problem finding fuel and neither did we including for an LS powered 100 series that ate fuel at an alarming rate.

I think this fuel range thing is a bit of a beat up..oh and I asked my travelling mate Bruce today if all fellow travellers have 200s with huge heavy tanks ..he laughed and said no..matter if fact he said we've seen lot of cars like yours..ie D4s.

in fact what i have said previously is they are a fantastic tug.Probably one of the best around.

Having owned one for almost 10yrs,maybe i would have some sort of idea?

My mates prado has 150ltr standard so i can only compare what i have personal experience with.

Well my brother had a 2014 200 Series Sahara TDV8 and we often compared it with my RRS - not much in it as far as range goes in similar conditions. In fact the Cruiser was so bad that my brother sold it and bought a Chev Silverado HSV last year which he says is far superior with its 6.? litre TDV8 than the Cruiser.

He went away with his Cruiser towing his van with my other brother in his 2011 Hilux towing his van and the cruiser used almost twice the amount of fuel of the Hilux.

Those 4.5 Twin Turbo Toyota diesels have a real reputation of chewing through the juice - even when not towing.

I asked the question earlier but no one responded - why is the usable fuel in the D4 far worse than a D3/RRS. My RRS has a 84 litre tank and I have put in more than 80 litres on a few occasions with a max fill of 82 litres and distance of just over 1100km.

That’s excellent mileage

Dunno,they are just like that,there are other threads on this subject.(D4fuel tank size)

The D2 also had a good sized tank.

Some of the LC200 models also had different sized tanks,around the 95 litre mark from memory,which can confuse the ‘how far I went on a tank ‘ comments.
Generally,after the facelift,they had the larger tanks and were better on fuel than the earlier model runs,different injectors,etc,etc.

I better buy a RRS as there is no way my 08 D3 can go 1100km on a tank. I have never seen the computer tell me a number less than 10l/100 and the bowser certainly tells me it can not do single figure numbers/100ks no matter how i drive it. I have travelled with other D3's and they dont get that range either from the standard 84 ltr tank

my 07 RRS could easily return approx 1000 K's on one tank, but it was based on the 2.7 V6, my 10.5 RRS is lucky to give anything
beyond 650-700K's on a run between Sydney and North Queensland, the 3.0 twin turbo is a tad thirstier than the 2.7.

Reading this thread, it seems people are randomly comparing diesel and petrol consumption, for both normal driving and towing which doesn't really make much sense...

The P400 engine is just about 100PS (pferdestarke or German metric horsepower) more powerful than any petrol V8 fitted to any Discovery and has about 150Nm more torque, so a pretty impressive engine for a straight 6. However, as everyone knows, fuel consumption on a petrol is directly related to your right foot, so guys have been posting up some very widely spaced consumption rates. THese are however directly related to their driving style rather than an attribute of the engine's performance.

Anything between 12l/100km to 19l/100km have been quoted and the guy who did the 19l/100km was towing a 3 ton trailer with timber over the Rocky Mountains near Banff. The P400 is an awesome engine, but like the joys of driving a V8, it comes at a price.

I'm waiting to order a 90 and I'll be looking a the diesel i6 D250 for various reasons, but we know absolutely nothing about those engines and their fuel consumption as they are brand new for 2021. I suppose we will just have to see how the insane torque figures of 570Nm for the D250 with combined consumption figures lower than 9l/100km (quoted) goes as a tow vehicle.


Cheers,

Lou

Well you have an issue either with your driving style or your vehicle.

My display regularly shows 6.6l/100km (which is a real 7.4l/100km) cruising on the freeway at 110kph - but then I have a aerodynamic Sport and not a brick fridge D3 [thumbsupbig]

The best my D4 2.7L has ever done is 9.2l/100,calculated,that was on a 600KM run,empty apart from myself and the dog.
And on the speed limit all the way,some sections at 110km/hr.
Cooler weather as well,which always helps diesels.

But generally,loaded,nothing on the roof,it will do 10 to 11l/100,on a run,at the speed limit.

I have given up with the dash readout,always calculate fuel usage.

The D3/4 is larger and probably heavier than a Sport,which won't do it any favours fuel consumption wise.

But its still not bad for a heavy brick shaped vehicle.
