Voici les mod\u00e8les embl\u00e9matiques et les marques o\u00f9 on les retrouve le plus fr\u00e9quemment :<\/p>\n

1. La marque embl\u00e9matique : Lamborghini<\/span><\/h3>\n

C’est Lamborghini qui a rendu ces portes mythiques en les introduisant d\u00e8s <\/span>1974 avec la Countach<\/span><\/b>.<\/span> Depuis, presque toutes ses supercars \u00e0 moteur V12 en sont \u00e9quip\u00e9es :<\/p>\n

    2. Autres supercars et hypercars iconiques<\/h3>\n

      3. Les voitures plus accessibles ou quotidiennes<\/h3>\n

      M\u00eame si le m\u00e9canisme est complexe et co\u00fbteux, quelques mod\u00e8les plus grand public ou atypiques en ont b\u00e9n\u00e9fici\u00e9 :<\/p>\n

        \n
      • \n

        Toyota Sera<\/b> (1990-1995) : un petit coup\u00e9 japonais m\u00e9connu mais rest\u00e9 c\u00e9l\u00e8bre pour ses portes \u00e9lytre\/papillon en verre (qui ont d’ailleurs inspir\u00e9 Gordon Murray pour la McLaren F1).<\/p>\n<\/li>\n

      • \n

        Renault Twizy<\/span><\/b> : le petit quadricycle \u00e9lectrique urbain propose des demi-portes optionnelles qui s’ouvrent en \u00e9lytre.<\/p>\n<\/li>\n

      • \n

        MG Cyberster<\/span><\/b> : le roadster 100 % \u00e9lectrique moderne.<\/p>\n<\/li>\n<\/ul>\n

        • \n

          McLaren<\/span><\/b> : la marque utilise un syst\u00e8me similaire appel\u00e9 portes di\u00e8dres<\/b> (Dihedral Synchro-Helix)<\/i> : la porte s’\u00e9l\u00e8ve en pivotant l\u00e9g\u00e8rement vers l’ext\u00e9rieur et l’avant (vu sur la F1, P1, 720S, Artura).<\/p>\n<\/li>\n

        • \n

          Koenigsegg<\/span><\/b> : la marque su\u00e9doise utilise son propre syst\u00e8me brevet\u00e9 (Dihedral Synchro-Helix Actuation<\/i>) o\u00f9 la porte sort vers l’ext\u00e9rieur avant de pivoter \u00e0 90 degr\u00e9s vers le haut.<\/p>\n<\/li>\n<\/ul>\n

          \"\"<\/p>\n

          Le syst\u00e8me brevet\u00e9 par Koenigsegg, appel\u00e9 Dihedral Synchro-Helix Actuation<\/b>, combine un d\u00e9placement vers l’ext\u00e9rieur et une rotation \u00e0 90 degr\u00e9s gr\u00e2ce \u00e0 un m\u00e9canisme de charni\u00e8re complexe.<\/p>\n

          Fonctionnement cin\u00e9matique<\/h3>\n

          La cin\u00e9matique d’ouverture se d\u00e9compose en trois actions simultan\u00e9es :<\/p>\n

            \n
          1. \n

            D\u00e9gagement lat\u00e9ral<\/b> : La porte sort l\u00e9g\u00e8rement de sa niche pour s’\u00e9carter du ch\u00e2ssis.<\/p>\n<\/li>\n

          2. \n

            Rotation \u00e0 90\u00b0<\/b> : Un pignon guid\u00e9 par une cr\u00e9maill\u00e8re ou un c\u00e2ble fait pivoter la porte vers le haut.<\/p>\n<\/li>\n

          3. \n

            Ascension verticale<\/b> : En pivotant, le m\u00e9canisme \u00e9l\u00e8ve la porte pour qu’elle se retrouve parfaitement perpendiculaire au sol, au-dessus du niveau du trottoir.<\/p>\n<\/li>\n<\/ol>\n

            Avantages techniques<\/h3>\n
              \n
            • \n

              Encombrement lat\u00e9ral minimal<\/b> : La porte sort tr\u00e8s peu vers le c\u00f4t\u00e9 avant d’entamer sa rotation, ce qui permet d’ouvrir la voiture m\u00eame stationn\u00e9e pr\u00e8s d’un obstacle ou d’un autre v\u00e9hicule.<\/p>\n<\/li>\n

            • \n

              Acc\u00e8s optimal au cockpit<\/b> : Une fois la porte redress\u00e9e \u00e0 90\u00b0, l’ouverture est totale et d\u00e9gage tout le seuil de porte sans g\u00eaner la t\u00eate de l’occupant.<\/p>\n<\/li>\n

            • \n

              Pratique pr\u00e8s des trottoirs<\/b> : Le mouvement de lev\u00e9e initiale emp\u00eache le bas de la porte d’accrocher les bordures \u00e9lev\u00e9es.<\/p>\n<\/li>\n<\/ul>\n

              Mod\u00e8les \u00e9quip\u00e9s<\/h3>\n

              Ce m\u00e9canisme \u00e9quipe la totalit\u00e9 des mod\u00e8les de la marque su\u00e9doise depuis la CC8S<\/b> (2002) jusqu’aux mod\u00e8les r\u00e9cents comme les Agera<\/b>, Regera<\/b>, Jesko<\/b> et la GT quatre places Gemera<\/b>. Sur les mod\u00e8les modernes, tout le syst\u00e8me est contr\u00f4l\u00e9 \u00e9lectriquement et hydrauliquement (Autoskin<\/i>).<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n
