Light duty vs heavy duty homologation

[jako999]

Hi all what is the difference between light duty and heavy duty homologation apart from £1000, which is the best to order and why?

Before someone says it I know it’s the engine and I know it has something to do with emmisions
Thanks

Do you mean between the ducato or Ducato Maxi? If so its weight capacity, brakes and suspension AFAIK

A little bit of reading HERE suggests that it relates to the emission standard testing for vehicles above or below 3500kg, in post #1 are you saying that the £1000 is the difference if you order a MoHo plated at over 3500kg.

OK a little bit more reading and now I understand your confusion jako999 for the Arto they list two engine specs both nominal 2.3 but light and heavy duty homologation and the light duty has 10bhp more and more torque it also shows upgrade options taking it even higher output, the heavy duty is much less upgradeable.

So you would think that everybody will just order the Light duty BUT reading the small print,

7) All Arto models with Light Duty homologation with weight upgrade and/or 18" alloy wheels can only be registered in Germany with an individual approval. No COC available.

It really is about time the EU treated M1 class more appropriately. There is a huge difference between a heavy truck doing 100K miles/year and a motorhome doing 5K

IMO the Euro emissions standards have already gone beyond the point of sanity with 6d. This is supposed to be about global warming but we re making diesel engines run ever hotter ( which btw makes them burn more oil), how does putting ever hotter air into the atmosphere help? And if we werent so concentrated on strangling them they might be actually burning less . They re now at the point where it has to effect the longevity of the engines hence a larger carbon foorprint required to produce more engine parts.

The various emissions schemes are forcing the replacement of perfectly good trucks and where do the now redundant older trucks go? third world countries where the first thing they do is bypass as much of the emissions tech as they can to make them easier to service and more reliable. Its the same planet they re warming just in a different place.

So the logic is - we will sell you a shorter Arto at 3500kgs but you re going to have to have a Gutachten to prove that it is actually possible to run it under 3500kgs.

Thats very honest of them but its going to cost them some sales unless the rest of the manufacturers do the same.

No even the 76L the smallest and lightest is 3600kg MIRO so they seem to offer the more powerful light duty engine that can possibly be registered outside of Germany but not in Germany without their equivalent to SVA.

Ahh, so if you want a smaller one you have to have an I-smove I take it? Thats another market they re missing then IMHO - people who want a quality A class but have restricted space or are not comfortable with the extra metre or so.

Even the iSmove starts at 7m though mainly through the obsession with single beds and island beds IMO.

Thanks for that.
So basically would I be right in saying if I want to use it in multiple countries I’m better off going heavy?

If you wanted to sell in Germany some time in the future for example you might be better off with a heavy but as far as registering it in the UK and then using it anywhere you fancy should be OK as far as I understand it but I would want somebody else to back that up as it’s just my interpretation from reading.

You can have the light duty uprated to 180BHP but the Heavy will only go as far as 160 from Fiat, I don't know what they do for the 180 upgrade on the light as it's an extra 10kg.

Honestly? IMHO you would be better off buying a 2nd hand Euro 4/5 3 litre, better engine, quieter and more robust and less fussy MH, there might be some city centres you need to avoid but most of us do anyway.

We had a 3.0 Niesmann before our mistake of a Carthago and I have to say what a cracking engine it was and a great van only hope the new one is built as well.
Thanks
