Infiniti arrive au SEMA Show 2025 avec une proposition aussi audacieuse qu\u2019impressionnante : le QX80 R-Spec Concept.<\/p>\n

Ce prototype reprend la base du grand VUS QX80, mais la transforme en une b\u00eate de performance propuls\u00e9e par un moteur biturbo de Nissan GT-R gonfl\u00e9 \u00e0 1000 chevaux. Ce concept, qui suit le QX80 Track Spec d\u00e9voil\u00e9 cet \u00e9t\u00e9 \u00e0 The Quail, pousse encore plus loin la vision d\u2019un VUS de grand luxe \u00e0 la sauce performance.<\/p>\n

Un moteur de GT-R\u2026 sous le capot d\u2019un QX80<\/strong><\/p>\n

Alors que le Track Spec se contentait du V6 biturbo de 3,5 litres du mod\u00e8le de s\u00e9rie, port\u00e9 \u00e0 650 chevaux, le R-Spec monte d\u2019un cran. Sous son capot se loge le V6 biturbo de 3,8 litres de la Nissan GT-R R35, largement modifi\u00e9 pour atteindre la barre des 1000 chevaux. Le moteur a \u00e9t\u00e9 enti\u00e8rement retravaill\u00e9 : turbocompresseurs Garrett G-series, double intercooler, collecteurs d\u2019\u00e9chappement sur mesure, nouveau syst\u00e8me d\u2019alimentation et pistons renforc\u00e9s.<\/p>\n

La transmission re\u00e7oit des refroidisseurs suppl\u00e9mentaires, tandis qu\u2019un diff\u00e9rentiel arri\u00e8re \u00e9lectronique verrouillable compl\u00e8te l\u2019ensemble.<\/p>\n

Des freins et une suspension \u00e0 la hauteur<\/strong><\/p>\n

Avec pr\u00e8s de 6500 lb sur la balance, il fallait du s\u00e9rieux pour stopper cette machine. Infiniti a donc repris les freins en carbone-c\u00e9ramique de la GT-R, une premi\u00e8re sur un QX80.<\/p>\n

Le concept repose sur une suspension \u00e0 combin\u00e9s filet\u00e9s sp\u00e9cialement d\u00e9velopp\u00e9e pour abaisser le centre de gravit\u00e9 et am\u00e9liorer la tenue de route. Il roule sur des jantes de 24 pouces de couleur bronze inspir\u00e9es de la GT-R, chauss\u00e9es de pneus Yokohama Parada Spec-X de 315 mm de large.<\/p>\n

Un style agressif et spectaculaire<\/strong><\/p>\n

Visuellement, le QX80 R-Spec en met plein la vue. Sa carrosserie \u00e9largie et son kit a\u00e9rodynamique rappellent le design de la GT-R T-Spec Takumi Edition, qui marquait la fin de la lign\u00e9e R35 en 2024.<\/p>\n

\u00c0 l\u2019avant, un pare-chocs retravaill\u00e9 avec de nouvelles prises d\u2019air, un splitter pro\u00e9minent et des feux antibrouillard int\u00e9gr\u00e9s donnent le ton. \u00c0 l\u2019arri\u00e8re, un diffuseur massif, quatre sorties d\u2019\u00e9chappement et un aileron prononc\u00e9 compl\u00e8tent le look.<\/p>\n

Le tout est envelopp\u00e9 d\u2019un film violet iridescent qui passe du bleu profond au pourpre royal, avec des reflets rouges et orang\u00e9s selon la lumi\u00e8re \u2014 un effet spectaculaire digne d\u2019un concept-car SEMA.<\/p>\n

Pas pour la production, mais un message clair<\/strong><\/p>\n

M\u00eame si Infiniti n\u2019a pas l\u2019intention de produire un QX80 de 1000 chevaux, le R-Spec envoie un signal fort : la marque veut injecter plus de sportivit\u00e9 dans sa gamme de VUS de luxe.<\/p>\n

Selon un cadre d\u2019Infiniti, une version plus performante du QX80 est bel et bien \u00e0 l\u2019\u00e9tude, et le r\u00e9seau de concessionnaires aurait d\u00e9j\u00e0 manifest\u00e9 un fort int\u00e9r\u00eat pour un mod\u00e8le inspir\u00e9 du Track Spec.<\/p>\n
