Thread: Can a Disco 4 tow a van with 350kg ball weight... I think not fit for purpose..

Keep under the below and all is good.....

GVM 3240, you mentioned 320kg tow ball therefore 2920 is the number you’re chasing without the van connected ...with a 2600 tare than you have 300 payload.

Max. Tow ball 350 which you’re under

GCM.....couldn’t see a reference

ATM 2700, can be difficult to achieve with some manufacturers.

I think GVM is reduced by 320 - 150 = 170 … my interpretation of owners manual page 70. It says reduce GVW by 200 if 350 TBM... I am assuming a sliding scale of 1kg less GVM for each additional TBM over 150. This gives 130 payload... My wife and I will both need to diet... I hope to get TBM down to 270 which gives me 180 payload which I can work with..

The ATM of 2,700 is the latest ALKO Outback suspension Rating. The van has a payload of 550kgs

well shoot, looky thare, its right here in the brochure, page 47...

kerb (tare) mass includes fluids, tools, spare and 75kg driver.

Interesting, two threads going at the same time on much the same topic. This is one I started a few days ago, and updated today after another visit to the weighbridge:

Have I got my weight sums right?

David you might find some comfort in my most recent post:

Just took the D4 over the weighbridge again, this time to measure weight over the rear wheels only. Came in at 1,660kg, so with gross vehicle weight currently at 3,040kg including me and the bride and full fuel, fridge, rear drawer and some odds and sods, I'm assuming that means there's 1,380kg over the front wheels (1450kg max allowable)

In any case, gives me some comfort, knowing max allowed rear axle weight of 1,885kg gives me about 225kg wriggle room at the back end. If I can get the camper trailer nose weight down to 150kg or thereabouts, happy days.

It weighed 2,620 kilos and the difference between this and the weight in the owners manual accounts for the fuel. I have also asked Land Rover to verify this.
My interpretation is that it can support a 150kg TBM with no impact of the GVM of 3,240
If the TBM is above 150kgs, then the GVM is reduced by 1kg for each kg the TBM is above 150
I think the D4 is a brilliant Tow vehicle, but like every other 4X4 and Ute, you have to watch all the weights. The discerning Motoring press are waking up to this and exposing the real towing capacities of our vehicles. Obviously they are quoting the latest Disco which I don't have the owners guide for to read the small print for towing to determine if it has the same limitations as the D4..

Not the GVM, only the payload, is reduced if the TBM is above 150kg, I think, as a non-expert. Recommend you check this.

I think ive read somewhere the 2.7L gets a bigger payload than the 3.0L

finally a win for the little guy 👍

I have no problem driving at speed limits and when overtaking road trains I have been able to get well over 160kph. I have never felt any problems towing and going up many hills I pass most (if not all) vehicles towing any type of van if they are not at the speed limit. It was one of the reasons I bought the d4. I have toyed with notion of a remap, but as yet have not done so. Recently I put the shunt on wiring so that the car recognized a van was attached. It has made an immediate impact in that I now get 1.5l p 100 kms better fuel economy. I dont understand that but it has lowered it from 15.8 down to 14.3, And that is driving on highways at the speed limit not at 90kph!

When the car recognizes that it's towing a van the throttle response is adjusted, and I believe the torque curve shifted lower in the rpm range, so the car is doing less work higher in the rpm range, that saves fuel.

Many thanks for this... I cant reconcile the numbers with my visit to the Weighbridge yesterday, but happy to concede its the position...

Hi Mick, I am only quoting what is in the owners handbook, and it definitely says GVW.

Regarding the tare weight, Roverlord has produced evidence that the EU do include Fluids and 75kg person in kerb weight.. as said before, I cant reconcile this with my visit to the weigh bridge, but for me I now have my starting point and the only outstanding issue is verifying beyond doubt if and how GVW is adjusted by TBM over 150kgs.. I will keep investigating..
