Your car's body components have been developed as an integral part of the vehicle's passive safety system, in order to ensure optimum protection for pedestrians and for all vehicle occupants.
They also create the vehicle's style, designed and manufactured to
maintain their characteristics over time: to avoid rust formation, the
panels are zinc-plated in advance on both sides, to a
thickness of between 7 and 10 μm, then painted in a cataphoresis cycle.
The finished appearance of the paintwork is created using primer and top coat.
During the development phase, a range of experimental checks are performed, in which components undergo accelerated corrosion tests. These stimulate the most severe and demanding usage conditions in wet/cold regions.
All of these processes ensure high corrosion resistance:
the structural elements of the vehicle's body are guaranteed against
perforations caused by rust, when it occurs from the inside out.
The anti-perforation warranty provides for the
repair and/or replacement of any structural bodywork element damaged by
perforating rust, when it occurs from the inside out, and is valid for a
period of 8 years from when the vehicle is handed over to the customer. The paintwork warranty lasts for 3 years.
Check your warranty manual for the specific conditions which apply in your country.
If you need replacement parts, make sure you choose Mopar® original body parts which have been specially designed for your Fiat Professional car.
The bonnet covers the engine compartment, protecting it against direct damage from atmospheric agents, and is also an integral and distinguishing part of your vehicle's style.
The most commonly used material is steel, which can
be found in all of the parts which make up the bonnet. Depending on the
component, the steel may be high-resistance, to ensure optimum mechanical performance, as well as preventing buckling and denting.
Panel thickness is optimised to reduce vehicle weight: and more recently, aluminium panels have also been used on some models, offering lower CO2 emissions and reduced fuel consumption.
When designing bonnets, particular attention is paid to accidental collisions with pedestrians:
an international standard sets out the type approval of models in line
with specific parameters, to increase safety in the case of an accident
involving a pedestrian, up to certain speed limits.
During the design phase, the controlled crumple and deformation points are fixed,
to prevent the bonnet from moving back towards the windscreen and
injuring the vehicle occupants in the case of a front impact.
Opening the bonnet gives access to the engine compartment for routine maintenance and other interventions: to improve working conditions, the size of the opening is specifically designed in line with ergonomic research. Some models are fitted with gas springs which control the bonnet opening, offering increased comfort for vehicle maintenance personnel.
The role of the bumper is to prevent or limit damage during low speed collisions.
The bumper has a fundamental impact on the vehicle's style: today the
range of bumper configurations has expanded - the design of a vehicle's
bumper can reduce the dimensions of its bonnet, thus reducing weight and increasing performance.
The bumpers also play a part in the vehicle's aerodynamic performance, in turn optimising fuel consumption.
This part of the car is classed as a "sacrificial" element of the
system which protects the sensitive engine parts: thanks to its specific
crumple characteristics, it is used to protect parts which would
otherwise be broken or damaged upon impacts occurring during vehicle
manoeuvres, or during minor collisions with other vehicles. The bumper
also absorbs collisions, deflecting the energy flows created following an impact.
Bumpers capable of absorbing the energy of an impact have “controlled crumple zones” and can withstand minor collisions without suffering any damage.
There are several important aspects involved in original bumper type approval:
Mopar® original spare parts are supplied ready primed, treated with a special grey or black base known as primer. Priming optimises paint absorption and ensures perfect colour matching between plastic and metal parts, increasing the paint's resistance to washing.
The bonnet and the two wings create the style of the front section of the vehicle.The
wings cover the tyres to protect other vehicles from flying gravel
caused by the rotation of the wheels when the vehicle is in motion. The
wings are usually fitted with wheel compartment guards which reduce
noise from the engine inside the vehicle and help protect against flying
gravel. The wings are secured to the body with mechanical fixings, for
easy replacement in the case of maintenance or damage.
The shape of the wing plays a part in improving aerodynamic performance and meeting buckling and denting
The wings must pass international type approval tests relating to
pedestrian impact, which require the component to collapse upon impact,
within predetermined speed limits.
Wings are manufactured from highly recyclable materials such as steel, aluminium and plastic, with advanced mechanical performance. The choice of materials is guided by the trade-off between performance and weight objectives.
These protect the front and rear sections of the vehicle, limiting damage caused by collisions at speeds of up to 15 km/h, which typically take place in cities. Crossmembers are bolted on, and easily and cheaply replaced: they function as a kind of "fuse" for other components which are more expensive to repair or replace (for example bonnets, wings, radiators, tailgates or boot lids, light clusters, exhaust pipes, struts, etc.).The front and rear sacrificial crossmembers have controlled crumple zones. They are structured to absorb impacts at speeds of up to 15 km/h, which is statistically the typical speed of a shunt accident in an urban environment. The crossmember is one of the elements which improve your vehicle's passive safety, a component with the role of absorbing kinetic energy created by the vehicle and its occupants during a collision, in order to limit the consequences of an accident.
The component which absorbs energy in the case of a collision is known as the Crash Box and is connected to the vehicle's front struts and rear side members. This energy absorption
prevents the crumpling of components not bolted on (side members or
struts), or of sensitive vehicle components, such as the engine cooling
system. Here too, absorption is ensured by a controlled crumple zone.
These reduce possible bumper damage during minor collisions which may occur in the case of contact during parking manoeuvres.
On the outside, they ensure the continuity of the vehicle's shape and style and, when open, they offer sufficient space to access the passenger compartment. The doors protect the vehicle occupants from potentially dangerous intrusions caused by side or front impact and are without a doubt one of the most used vehicle components, especially the door which gives access to the driver's seat.
The door system is highly specific, made up of a range of materials:
there is always a structural skeleton, usually in steel or aluminium,
connected to the vehicle using hinges. This structure is then dressed
with all the accessories it needs to ensure a waterproof finish, the
functionality of the electric devices such as the windows, speakers and courtesy lights, acoustic comfort and an attractive interior aesthetic, both visually and to the touch.
The position, the shape and the operating loads of the door handles
are researched down to the smallest detail, to ensure smooth operation.
Ergonomic solutions ensure the optimum usage conditions for all door mechanisms.
The components of the door structure which play the biggest role in absorbing the energy which develops during a side impact have extremely high mechanical resistance.
To permanently crumple them would take a pressure of 1500 MPa (Mega
Pascal). To give you an idea, imagine the weight of an economy car
concentrated on the head of a drawing pin!
Following an accident at low speed, whether your
vehicle shunts or is shunted, there may seem to be very little damage to
the vehicle. Usually following a shunt impact, all we see is slight
scratching on the bumper. In reality, even if they can't be seen
from the outside, the sacrificial crossmembers may have worked hard,
and in the case of another accident, they may not be as efficient.Ensuring
your sacrificial crossmember is in perfect condition means your vehicle
will be safer: of all the components which play a key role in the
vehicle's passive safety, this is the first element which comes into
play in the case of a collision.
Mopar® original spare parts maintain their aesthetic and functional characteristics over time, thanks to:
The bonnet lock has a safety hook which prevents opening even when partially unlatched. Always keep your locking mechanisms clean and efficient. This is one more way of guaranteeing a safer journey.
If your vehicle is fitted with an active bonnet for pedestrian impacts, remember to service the system regularly as set out in the owner handbook.
Following a minor accident, be sure to have the condition of the sacrificial crossmembers carefully checked
to ensure their efficiency is maintained in the case of another
accident. Replacing a crossmember, even if only slightly deformed, may
avoid the need to repair or replace other components at a later date.
The doors are designed and tested to maintain
optimum functionality over time. To preserve door functionality, simply
follow the instructions in the owner handbook. However, taking a few
basic measures will help to maintain the efficiency of the door system
throughout your vehicle's lifetime:
