Protective treatments: (page 2 of 2)

The maximum noise inside the vehicle at 120 km/h in fifht gear for all versions (excluding the 1372 turbo) is equal to 73 decibels.

This has been achievely by mainly concentration on the following three areas of noise generation: engine, rolling, aerodynamics.

The main operations have been as follows:

• Improving the bodyshell; carefully studying all the components and fixings which creak, such as for example the dashboard and the seats. The rigidity of these components has been increased and the anchorage points have been reinforced with extreme care being taken over the selection of contact materials.
• Inserting a foam which polymerizes in the engine compartment struts which creates a barrier inside the box sections preventing the noise from entering the passenger compartment.
• A sound-deadening cover for panels using thermofusible materials applied before painting.
• A sound-insulation cover for the front of the dashboard, front and rear footrests, with pre-formed composite panels.
• Sound-proofing; very thick roof lining stuck to confer improved sound-insulation.
• The use of openings for passing the cables between the engine compartment and the passenger compartment with seals both in the panel and the sound-deadening material to reduct the transmission of the noise from the engine compartment to the passenger compartment.

Taking into consideration the excellent level of acoustics achieved, in the case of repairs the solutions adopted during manufacture should be guaranteed to the same level.
