Thread: Weighed today

Tombie on the good side with the D4 V8 it comes with every single option box ticked as standard, so it has everything.

On the bad side every single one of those options weighs something so that would explain such a large discrepancy. Re the Nitto's I would be surprised if they were LT spec.

Just spoke with an engineer who does vehicle Certification work for the RTA and asked about the possibility of increasing the GVM of the D3/4. He is pretty adamant that it can't be increased above the factory stated number. Reason, there is no D3/4 that has a higher GVM than 3240. However believe it or not a 110 Defender can be increased to a GVM of 3500 kg because a 130 has a GVM of 3500 kg supposedly.

Back to the drawing board.

So how does that logic work for 200 series cruisers gvm upgrades? I thought it would be limited by max axle loads even though in this case there is no load bearing "axle" per say

I think I will mark the page in the handbook. If the weights & measures boys pull me over, I will hand it to them. If they can work it out on the side of the road inside an hour, I might get a determination . Otherwise they will probably have to let me go...out of pity..maybe.

In the meantime, I will be be using the generally accepted method of calculation, just in case. Staying under the GVM ( including towball weight ), keeping the axle loads under the maximums, and under the total train weight. ( which should not be an issue, as the van is only 2500 odd kilos )

The 200 is done with springs, I'm betting it the airbags that nobody has got there head around yet. The 200 still has axle limits, I am unsure if the axle limits are changed which I must ask. Pretty sure dealers of some makes offer GVM upgrade and have new compliance plates fitted.

My colleague at work has done the upgrade using the same components that's needed to have it engineered but figured it was a waste of money paying for the certification as he still exceeds what the new GVM would be.

If there is a similar model that has a higher GVM then they can up spec any of the lower GVM models to the higher spec after mods.

I was told the 200 series is sold overseas with a higher GVM and the increased GVM here that ARB does is to the same amount as the overseas models. Maybe that is how they get around it.

That is how they can here up spec a Defender 110 so it has the same higher GVM as the 130. He said it had nothing really to do with air springs versus steel ones.

If there is any model D3/4 that has a higher GVM then there is a chance. I have asked in the Disco3uk forum what the GVM is of the D3/4 Commercial, so far there has been no feedback.

The article describes the Armoured Disco4 with GVM (over 3500kg)

Mention of upgrades to brakes and engine is made in the article.

The world of the armoured vehicle is all heavy duty - must be something here.

It doesn't actually state what the vehicles GVM is, it says the D4 on its own weighs 3550 kg. ...
