homologation new car models

[tvi71it]

Good evening, everyone.
I had today, by my owner, the task of finding (or understanding how this can be possible) the documentation inherent in the homologation of new car models.
the idea would be to realize a new body shop starting from an existing car, in order to understand us in a way similar to what makes the abarth or other Italian and foreign coaches, that starting from a series car, go to make aesthetic changes changing existing pieces or replacing them with other new ones of healthy plant. the intervention would concern, only the part of style, while the frame and the rest of the plants (electric, hydraulic, suspension, brakes etc...) would remain unchanged.
after this brief premise the doubts I have are as follows:
- the car must be re-homologated, although there are only aesthetic changes?
- in which institution and with which bureaucratic procedures should this be done?
(for Italy I would say that the agency is the civil motorization ... right? )
- Are there any regulations to be complied with that the motorization agency provides or if you have to buy them?
Is it necessary to produce documentation relating to structural checks, for example crash tests?
- any approximate costs for the whole homologation process

I thank in advance all those who will help me to answer these questions.

the intervention would concern, only the part of style, while the frame and the rest of the plants (electric, hydraulic, suspension, brakes etc...) would remain unchanged.

modern shells are carriers and many "pannelli" (paraurti, chests, mudguards) are integral part of deformation zones in case of impact. It is difficult to distinguish a priori what is not structural (which is different from the simple frame).

should the car be re-homologated, although there are only aesthetic changes?

depends, apart from the simple definition of "esthetic change", even a simple fanalino affects the homologation of the car.

- in which institution and with which bureaucratic procedures should this be done?
(for Italy I would say that the agency is the civil motorization ... right? )

any motorization in Europe.

- Are there any regulations to be complied with that the motorization agency provides or if you have to buy them?

the norms there are (European) available for payment at the dedicated sites http://www.tuv.it/servizi/prof/automotive_02_c.asp

Is it necessary to produce documentation relating to structural checks, for example crash tests?

The mechanism is different. a vehicle is homologated with a series of "fiches" (one twenty in total) that "mount" the homologation as a puzzle, each chip manages a component or a feature or system (fresh, performance, emissions, noise, fuel tank, etc.).
when you change a vehicle "lose" the chips affected by the change (it decides the motorization), and you have to get back the relative chips, the "mix" must be reunited in turn.
all starts from a firm point, the ost nothing of the original manufacturer, without that you do nothing.
a particular case is the unique specimen, simpler but the basic mechanism does not change, avoid individual chips, but you have to do everything related to the individual vehicle.

- any approximate costs for the whole homologation process

depends on how many evidence you have to do. The cost is relatively low, the state gets paid for every test, the problem is that the evidence you have to do in approved laboratories, almost all private and you have to pay them.

You should use an external consultant, at least at first to set the whole operation, look for a serious one, there are a bunch of "arronzatori".

The first thing you have to decide is things you have to do, I'm kidding. you have to evaluate whether to make the "preparator" (all unique specimens) or the transformer in small series (start the chips and you must be homologated first as an operator) or even as a manufacturer, but it does not seem to me your case.

If you want to do things seriously you have to (you should) work with a strong agreement with the original manufacturer, which must approve your changes and give you the obvious nothing. difficult, but not impossible.

hello president, in the meantime thank you for the precious "draws you gave me";
with your indications I will see to deepen the thing.

The first thing you have to decide is things you have to do, I'm kidding.

you're right it's just so... we do other...the pieces we produce them but we don't design them and we don't even do the style, but
to get out of this moment of crisis, we also consider the idea of being able to do another, unfortunately for now improvising a little (a lot) ...

to enter a little more in detail of the idea of the owner, he saw on some brochures that some German companies provide cars (mainly German) cut after the doors and with the frame of the already elongated back (full floor of wheels, suspensions, planting etc...). all the back area after cutting, is empty, and everyone can fill it with the style that best believes to realize that it is a pick/up, a particular station wagon etc...
I believe that certainly by contacting one of these suppliers, many regulatory aspects, they would be ready to clarify, as well as feel the opinion of a consultant.
production is assumed in about 10-12 cars year, to return investment.

to do what you say first the company must have the title of builder, what you get by accrediting the title of builders at the Ministry of Transport. the Ministry of Transport will ensure that your company is able to guarantee the repetitiveness of cars built compared to the approved prototype.
In fact, once a first model (prototype) is built, it must be presented with a technical report of the engineer (who signs and assumes all the responsibilities) at a test center of civil motorization.... not all motorizations do this examination but only some in Italy (for South Italy I know that it is the headquarters of napoli that pre-post).
Once the homologation for that model can start production in series

if instead it is unique models it is better to turn to the tuv

thank you ... in fact, from the indications of the president, I was just trying to understand more about the site of tuv italia... and I also went to look for the European directive (160 pages :frown which speaks precisely of the approvals.
I thought I read the accreditation speech as a builder. . that you rightly pointed out to me. .
Is there somewhere a summary of the whole process to be followed, which is, a circular of the Ministry of Transport?

Give me some time and I'll know how to give you more details....... I'm trying to do the same thing for the motorcycle industry.... just that I'm okay with the tuv for the homologation of unique specimens.
