Aston Martin DBX S : groupe motopropulseur et performances<\/h2>\n

La DBX S est \u00e9quip\u00e9e d’un V8 biturbo de 4,0 litres am\u00e9lior\u00e9. Gr\u00e2ce aux modifications apport\u00e9es aux turbocompresseurs, entre autres, la puissance passe \u00e0 534 kW (727 ch). La voiture passe ainsi de 0 \u00e0 100 km\/h en 3,3 secondes, tandis que le sprint \u00e0 200 km\/h est plus rapide de 0,3 seconde. La vitesse maximale reste de 310 km\/h. La sonorit\u00e9 du moteur est plus expressive gr\u00e2ce \u00e0 un \u00e9chappement modifi\u00e9. La transmission est assur\u00e9e par une bo\u00eete de vitesses \u00e0 embrayage humide \u00e0 neuf rapports qui r\u00e9partit le couple de mani\u00e8re variable entre les essieux avant et arri\u00e8re. <\/p>\n

Gain de poids et dynamique de conduite<\/h2>\n

Une grande attention a \u00e9t\u00e9 port\u00e9e \u00e0 la r\u00e9duction du poids pendant le d\u00e9veloppement. Gr\u00e2ce aux options d’all\u00e8gement, cette voiture est jusqu’\u00e0 47 kilogrammes plus l\u00e9g\u00e8re que la DBX707. Mais vous avez bien lu : il faut payer un suppl\u00e9ment pour avoir moins de poids. Un toit en fibre de carbone est disponible en option et permet d’\u00e9conomiser 18 kg et d’abaisser le centre de gravit\u00e9. De nouvelles jantes en magn\u00e9sium de 23 pouces sont \u00e9galement disponibles et r\u00e9duisent le poids non suspendu de 19 kg. D’autres options, telles qu’une calandre en polycarbonate et des barres de toit supprim\u00e9es, permettent de r\u00e9duire encore le poids. <\/p>\n

La suspension a \u00e9t\u00e9 recalibr\u00e9e. La suspension pneumatique et les amortisseurs ont \u00e9t\u00e9 r\u00e9gl\u00e9s pour mieux contr\u00f4ler les mouvements du corps. La limitation du roulis a \u00e9t\u00e9 port\u00e9e \u00e0 1,5 degr\u00e9, ce qui contribue \u00e0 une conduite plate. La direction est plus r\u00e9active de 4 %, ce qui accro\u00eet l’agilit\u00e9. Le rayon de braquage a \u00e9t\u00e9 r\u00e9duit d’un demi-m\u00e8tre pour atteindre 12 m\u00e8tres. Le freinage est assur\u00e9 par de grands disques en carbone c\u00e9ramique. <\/p>\n

\"Aston<\/figure>\n

D\u00e9tails ext\u00e9rieurs<\/h2>\n

L’ext\u00e9rieur se distingue par une calandre noire, un nouveau splitter, un diffuseur et des jupes lat\u00e9rales avec guides d’air. Les clients peuvent opter pour des garnitures suppl\u00e9mentaires en fibre de carbone et une livr\u00e9e en rouge Rosso Corsa, argent Trophy ou vert Podium. Les embouts d’\u00e9chappement sont superpos\u00e9s verticalement. Les embl\u00e8mes sont en m\u00e9tal et en \u00e9mail, avec un \u00ab\u00a0S\u00a0\u00bb rouge. <\/p>\n

Int\u00e9rieur et finition<\/h2>\n

\u00c0 l’int\u00e9rieur, la sellerie Alcantara de s\u00e9rie et le cuir semi-aniline en option attirent l’attention. Un th\u00e8me visuel avec des motifs \u00e0 chevrons sur les si\u00e8ges et les garnitures de toit (si le toit en fibre de carbone est choisi) souligne le caract\u00e8re sportif. Les ceintures de s\u00e9curit\u00e9 rouges et les logos \u00ab\u00a0S\u00a0\u00bb sur les si\u00e8ges, les seuils et le capot renforcent ce caract\u00e8re. Les ailes d’Aston Martin sont press\u00e9es dans le cuir avec une grande pr\u00e9cision. <\/p>\n

Le nouveau syst\u00e8me d’infodivertissement – d\u00e9velopp\u00e9 en interne – est de s\u00e9rie, de m\u00eame qu’un syst\u00e8me audio de 800 W avec 14 haut-parleurs. En option, un syst\u00e8me audio Bowers & Wilkins de 1 600 W avec 23 haut-parleurs, sp\u00e9cialement adapt\u00e9 \u00e0 l’int\u00e9rieur de l’Aston Martin DBX S. <\/p>\n

Disponibilit\u00e9 Aston Martin DBX S<\/h2>\n

L’Aston Martin DBX S peut \u00eatre command\u00e9e d\u00e8s maintenant. Les premi\u00e8res livraisons sont attendues au quatri\u00e8me trimestre 2025. Aston Martin r\u00e9affirme ainsi que les versions plus l\u00e9g\u00e8res et plus puissantes resteront un \u00e9l\u00e9ment incontournable de sa gamme. <\/p>\n
