11.1 Description

The sunroof fitted to Nuova Punto consists of a special, wide-glass system referred to as

“Skydome”, made up of two glass panels (one fixed rear panel and one front sliding pane) and

a front fin which acts as an air baffle.

The glass extends to such an extent that it takes the place of over 70% of the sheet metal roof

The glass allows, when closed, the external light to be let into the vehicle while allowing the

occupants inside the passenger compartment to have a very good vision of the outside. The

glass, allows, when opened, the roof compartment to be opened to approximately half its

surface area.

During the opening phase, the front mobile panel slides out of the roof panel (“spoiler”

In particular, the sunroof consists of the following:
