2585430 - INTRODUCTION - PANELS AND FRAME

The design of the vehicle gives it a unique personality with all the bodywork variants that respond to the multitude of different usages.At the front the grille and the headlamps are surrounded by plastic that protects against impacts at low speed.The side panel features the rounded shape of the windows in the front doors and the extensive rear glass which produce a sensation of light and brightness that contributes to driving comfort.The sliding side doors, the two rear asymmetrical doors or the tailgate do not alter the sense of harmony of the model but fit in naturally with the exterior design of the vehicle.

PASSIVE SAFETY

The main objective of the features adopted in terms of passive safety is to create a survival chamber which, in the case of an accident, offers the passengers effective protection.The bodyshell of the veihcle has been designed for controlled deformation in the case of front, side and rear impact and to absorb the energy developed by the impact without adversely affecting the vital spaces in the passenger compartment.

BENDING AND TORSIONAL STRENGTH

The high torsional and bending strength of the bodyshell guarantees the vehicle excellent passive resistance qualities producing a sensation of solidness and comfort when driving.These excellent values also guarantee that the original specifications of the bodyshell are maintained over a period of time and there are no structural weaknesses that could adversely affect safety.

RESISTANCE TO FRONT IMPACTS

The main operations to the bodyshell for resistance to front impacts involve:

  • front crossmember
  • crash-box
  • bonnet retaining hooks
  • reinforcements on struts
  • reinforcements on front pillars

RESISTANCE TO FRONT IMPACTS

The vehicle comforms with front impact standard ECE R94 with the barrier offset in relation to the axis of the vehicle (cover of front section equal to 40%) at 56 Km/hIn this test checks are carried out on both structural measurements (made on the vehicle) and biomechanical ones (made on the occupant); the effects on the occupant are measured using special dummies.

Front crossmember

Front crossmember

The front crossmember and the crash-box are a new feature in the range of group vehicles because the structural elements are integrated and fitted on the bodyshell using bolts.They have been designed to reduce repair costs following impacts at low speed.In the case of a front impact at 16 km/h with an offset barrier (front covering of the vehicle equal to 40%) only these two components are deformed.The particular shape of the crossmember and the material from which it is made (highly resistant steel) guarantee that with this type of impact there is the minimum intrusion protecting the mechanical components.
If the body is repaired, the structural reinforcements should always be replaced if deformed.

RESISTANCE TO SIDE IMPACTS

In the case of side impacts the bodyshell is capable of offering a high level of safety, providing programmed deformation which does not adversely affect the survival chamber.

The above has been achieved by:

  • reinforcing the centre pillar
  • adopting connecting ribs between the side pillars
  • with the anti-intrusion bars and waist reinforcements on the doors

RESISTANCE TO SIDE IMPACTS

The vehicle conforms to side impact regulation ECE R 95 against a deformable barrier (centred in relation to the front seat positioned midway and adjusted to the lowest position) at 50 Km/h.
If the body is repaired, the structural reinforcements should always be replaced if deformed.

RESISTANCE TO REAR IMPACTS

The main operations to the bodyshell for resistance to rear impacts involve:

  • rear crossmember
  • crash-box
  • reinforcements on floor panel

RESISTANCE TO REAR IMPACTS

The vehicle conforms to the "Japanese" rear impact standards against a rigid barrier at 50 Km/h (covering of the rear of the vehicle equal to 100%).

RESISTANCE TO REAR IMPACTS

The rear crossmember and the crash-box are a new feature in the range of group vehicles because the structural elements are integrated and fitted on the bodyshell using bolts.They have been designed to reduce repair costs following impacts at low speed.In the case of a rear impact at 16 km/h against an offset barrier (rear covering of the vehicle equal to 40%) the floor panel is not deformed.
If the body is repaired, the structural reinforcements should always be replaced if deformed.

SOUND INSULATION

The CEE standards set an exterior noise level for the vehicle of 74 decibels, whilst for the interior of the passenger compartment, at a speed of 120 Km/h in fifth gear it is 73 decibels (76 decibels for the CARGO).

The improvement in driving comfort, in terms of quietness and quality inside the passenger compartment, has been mainly achieved through working on the following areas where noise is produced:

  • rolling
  • engine
  • aerodynamic
All the engine types used on the vehicle belong to a new generation with technological features designed to improve acoustics and vibrations.This same concept it also valid for the drive transmission components, the suspension and the bodyshell mountings.Diagram showing internal noise figures for slow acceleration in 5th speed:

SOUND INSULATION

The sound insulation material mainly comprises bitumen.Their task is to dampen the noise coming from mechanical vibrations in areas such as, for example, the underbody and the interior of the doors.The thermo-expandable materials are made up of rubbers or synthetic resins and have the task of damping the box sections to eliminate acoustic propagation (noise, whilstling).When the bodyshell goes in the ovens during the painting cycle these materials expand and vulcanize adhering to the inner surfaces of the panels with which they come into contact, completely filling the box section cavities.
taking into consideration the high level of acoustic comfort achieved, the specifications adopted during manufacture must be restored exactly in the event of repair.
