Mercedes-AMG a d\u00e9voil\u00e9 le coup\u00e9 GT 4 portes enti\u00e8rement \u00e9lectrique, d'une puissance de 860 kW et d'une capacit\u00e9 de charge maximale de plus de 600 kW. Les commandes pour ce mod\u00e8le haute performance seront ouvertes dans les prochains jours, dans un premier temps avec les variantes de motorisation GT 63 et GT 55. Et pour les amateurs de voitures de sport \u00e0 qui le bruit d'un V8 rugissant manque, il existe un mode qui permet d'y parvenir.<\/strong><\/p>\n

Le coup\u00e9 GT 4 portes enti\u00e8rement \u00e9lectrique est le premier mod\u00e8le construit sur la plateforme AMG.EA de Mercedes-AMG. Il est propuls\u00e9 par trois moteurs \u00e0 flux axial, dont la puissance de pointe peut atteindre 860 kW.<\/p>\n

Mercedes souligne que le mod\u00e8le incarne \u201cl'esprit pionnier d'Affalterbach avec de nombreuses premi\u00e8res mondiales\u2019. Il s'agit du nom de la ville situ\u00e9e pr\u00e8s de Stuttgart, dans le sud de l'Allemagne, o\u00f9 se trouve le si\u00e8ge de Mercedes-AMG GmbH.<\/p>\n

Innovante<\/strong><\/p>\n

Le coup\u00e9 GT \u00e0 quatre portes pr\u00e9sente plusieurs innovations. Mercedes-AMG utilise pour la premi\u00e8re fois des moteurs \u00e0 flux axial dans un mod\u00e8le de s\u00e9rie et les associe \u00e0 une batterie de 800 volts d\u00e9riv\u00e9e de la technologie de la Formule 1. Ses cellules cylindriques \u00e0 refroidissement direct sont con\u00e7ues pour fournir une puissance rapide, reproductible et soutenue, un \u00e9l\u00e9ment essentiel de la promesse de la marque AMG.<\/p>\n

Deux versions de motorisation seront disponibles d\u00e8s l'ouverture des commandes dans quelques jours : les versions 63 et 55. \u201cLes prix des mod\u00e8les seront bas\u00e9s sur ceux des v\u00e9hicules pr\u00e9c\u00e9dents comparables\u201d, pr\u00e9cise Mercedes-AMG.<\/p>\n

Ces mod\u00e8les sont actuellement commercialis\u00e9s aux alentours de 180 000 et 160 000 euros respectivement. Notamment, Mercedes n'a pas mentionn\u00e9 la version 43, le mod\u00e8le d'entr\u00e9e de gamme \u00e0 combustion interne du coup\u00e9 GT 4 portes, pour le lancement de la nouvelle g\u00e9n\u00e9ration \u00e9lectrique. On ne sait pas encore si elle sera introduite plus tard.<\/p>\n

\"\"<\/p>\n

Centrale<\/strong><\/p>\n

Sur le plan technique, le nouveau moteur est centr\u00e9 sur un concept de transmission purement ax\u00e9 sur la performance. Le v\u00e9hicule devrait acc\u00e9l\u00e9rer de 0 \u00e0 100 km\/h en seulement 2,1 secondes, et de 0 \u00e0 200 km\/h en 6,4 secondes. Mercedes-AMG annonce une vitesse maximale de 300 km\/h (avec le \u2018Driver's Package\u2019). Veuillez noter que ces chiffres, ainsi que tous les chiffres ult\u00e9rieurs, sont encore pr\u00e9liminaires.<\/p>\n

En mode AMGFORCE S+, le v\u00e9hicule d\u00e9livre un son authentique du V8<\/strong> et simule l'interruption de la traction lors des changements de vitesse.<\/p>\n

Les trois moteurs \u00e9lectriques innovants du coup\u00e9 GT 4 portes d\u00e9livrent une puissance de pointe de 860 kW (1 169 ch) dans la version 63. La version 55 offre une puissance de 600 kW. Selon Mercedes-AMG, ce n'est pas la limite : l'architecture est technologiquement capable de supporter des puissances encore plus \u00e9lev\u00e9es, de plus de 1 000 kW, affirme le constructeur. Notamment, les moteurs \u00e0 flux axial tournent \u00e0 plus de 13 000 tr\/min en vitesse de pointe.<\/p>\n

Les moteurs sont int\u00e9gr\u00e9s dans une unit\u00e9 de traction \u00e9lectrique haute performance (HP.EDU) au niveau de chaque essieu. Au niveau de l'essieu arri\u00e8re, cette unit\u00e9 abrite deux moteurs \u00e0 flux axial, chacun associ\u00e9 \u00e0 un r\u00e9ducteur plan\u00e9taire compact dans un seul bo\u00eetier. Il est important de noter que les moteurs et les r\u00e9ducteurs sont refroidis \u00e0 l'huile. L'unit\u00e9 de commande de pompe requise, avec les pompes hydrauliques et les filtres d'aspiration, est \u00e9galement int\u00e9gr\u00e9e de mani\u00e8re peu encombrante dans le HP.EDU. En outre, deux variateurs au carbure de silicium refroidis \u00e0 l'eau - un par moteur - sont inclus.<\/p>\n

L'unit\u00e9 avant HP.EDU comprend un moteur, un r\u00e9ducteur \u00e0 engrenages droits avec un verrou de stationnement int\u00e9gr\u00e9, une unit\u00e9 de contr\u00f4le de la pompe et un onduleur SiC refroidi par liquide. \u201cLe moteur \u00e0 flux axial atteint plus de 15 000 tr\/min en vitesse de pointe\u201d, souligne AMG.<\/p>\n

Le moteur \u00e9lectrique avant agit comme un \u2018moteur d'appoint\u2019, ne s'enclenchant que lorsqu'une puissance ou une traction suppl\u00e9mentaire est requise par l'essieu avant. Pour am\u00e9liorer l'efficacit\u00e9 \u00e0 faible charge, le moteur \u00e9lectrique de l'essieu avant peut \u00eatre rapidement d\u00e9coupl\u00e9, ce qui r\u00e9duit les pertes de charge inutiles. La connexion est r\u00e9tablie tout aussi rapidement lors de l'acc\u00e9l\u00e9ration et de la r\u00e9cup\u00e9ration.<\/p>\n

Cellules cylindriques, 800 volts<\/strong><\/p>\n

En ce qui concerne la toute nouvelle batterie du coup\u00e9 GT 4 portes, la batterie \u00e9lectrique AMG haute performance (AMG HP.EB) est le fruit d'une \u00e9troite collaboration entre les ing\u00e9nieurs de Mercedes-AMG \u00e0 Affalterbach et de Mercedes-AMG High Performance Powertrains (HPP) \u00e0 Brixworth, en Angleterre.<\/p>\n

La batterie int\u00e8gre l'exp\u00e9rience acquise en Formule 1 et le d\u00e9veloppement de l'hypercar Mercedes-AMG ONE. Elle est con\u00e7ue pour offrir les performances typiques d'AMG tout en offrant une autonomie adapt\u00e9e \u00e0 sa cat\u00e9gorie de prix.<\/p>\n

\u201cLe concept de batterie est con\u00e7u pour permettre \u00e0 l'avenir des autonomies WLTP bien sup\u00e9rieures \u00e0 700 kilom\u00e8tres\u201d, pr\u00e9cise AMG. Actuellement, le constructeur indique une autonomie de 600 \u00e0 700 kilom\u00e8tres.<\/p>\n

Les principales innovations de la batterie comprennent des cellules de batterie nouvellement d\u00e9velopp\u00e9es, un syst\u00e8me innovant de refroidissement direct pour chaque cellule et une tension relativement \u00e9lev\u00e9e. La cellule est cylindrique, haute et \u00e9troite : elle mesure 10,5 centim\u00e8tres de hauteur et 2,6 centim\u00e8tres de diam\u00e8tre.<\/p>\n

Il est important de noter que les cathodes des cellules comportent un mat\u00e9riau actif NCMA (Nickel\/Cobalt\/Mangan\u00e8se\/Aluminium) d\u00e9velopp\u00e9 sur mesure. La contrepartie est une anode contenant du silicium. AMG pr\u00e9voit des densit\u00e9s \u00e9nerg\u00e9tiques de plus de 298 Wh\/kg et de 732 Wh\/l au niveau de la cellule.<\/p>\n

Les d\u00e9veloppeurs concluent : \u201cGlobalement, la combinaison du format haut et fin, du bo\u00eetier en aluminium, de la technologie full-tab et de la chimie NCMA constitue la base d'une performance maximale, en particulier en termes de capacit\u00e9 de puissance continue, dans chaque cellule individuelle de la batterie\u201d. En outre, \u201cla haute tension du syst\u00e8me de stockage d'\u00e9nergie lithium-ion de 800 volts contribue \u00e9galement \u00e0 la performance globale\u201d.\u201d<\/p>\n

Gestion thermique intelligente<\/strong><\/p>\n

Au total, la Mercedes-AMG GT 4-Door Coup\u00e9 dispose de 2 660 cellules, regroup\u00e9es en 18 modules en plastique soud\u00e9s au laser. Le bo\u00eetier de la batterie fait lui-m\u00eame partie de la structure du v\u00e9hicule. Les modules en plastique int\u00e8grent un syst\u00e8me de refroidissement direct \u00e0 base d'huile pour les cellules cylindriques, AMG mettant en avant un liquide de refroidissement sp\u00e9cialis\u00e9 et une gestion thermique r\u00e9active : \u201cLa gestion thermique intelligente contr\u00f4le la temp\u00e9rature du liquide de refroidissement pour chaque module de cellule exactement \u00e0 la valeur requise\u201d. Cette approche est appel\u00e9e refroidissement \u00e0 la demande.<\/p>\n

Toutes ces innovations se refl\u00e8tent dans les performances de charge du v\u00e9hicule haute performance : le mod\u00e8le peut atteindre une puissance de charge maximale de plus de 600 kW.<\/p>\n

Selon Mercedes-AMG, la GT Coup\u00e9 peut recharger suffisamment d'\u00e9nergie pour parcourir environ 460 kilom\u00e8tres en seulement dix minutes. Le temps de charge de 10% \u00e0 80% est de seulement 11 minutes.<\/p>\n

La batterie peut \u00e9galement \u00eatre recharg\u00e9e plus doucement \u00e0 400 volts lors d'arr\u00eats plus longs. Autre point important pour la distribution mondiale : le coup\u00e9 Mercedes-AMG GT 4 portes est compatible avec cinq normes de recharge rapide : CCS2 en Europe, GB\/T en Chine, CHAdeMO au Japon, CCS1 en Cor\u00e9e du Sud et NACS aux \u00c9tats-Unis.<\/p>\n

\"\"<\/p>\n

Inspir\u00e9 par le concept<\/strong><\/p>\n

Mercedes-AMG avait d\u00e9j\u00e0 test\u00e9 les pierres angulaires des nouvelles technologies pour la quatre-portes de performance tout \u00e9lectrique avec la Concept AMG GT XX<\/a> en 2025. Au cours de ce processus, le concept car a battu plusieurs records, parcourant 40 075 kilom\u00e8tres en seulement huit jours.<\/p>\n

La vitesse optimale soutenue au cours de cet essai \u00e9tait de 300 km\/h, ce qui a impos\u00e9 des exigences correspondantes \u00e0 la technologie. En plus du coup\u00e9 GT 4 portes, un mod\u00e8le de la gamme GT 4 portes a \u00e9t\u00e9 mis au point. SUV tout \u00e9lectrique<\/a> bas\u00e9e sur la plateforme AMG.EA devrait \u00e9galement suivre, avec des tests d\u00e9j\u00e0 en cours depuis fin 2024.<\/p>\n

Ola K\u00e4llenius, pr\u00e9sident-directeur g\u00e9n\u00e9ral de Mercedes-Benz Group AG, parle d'un d\u00e9but impressionnant : \u201cJ'ai moi-m\u00eame conduit le nouveau coup\u00e9 AMG GT 4 portes \u00e0 de nombreuses reprises, et il se distingue v\u00e9ritablement. Il repousse les limites de la performance et procure l'\u00e9motion que nos fans attendent, maintenant dans l'\u00e8re \u00e9lectrique. Pour avoir travaill\u00e9 chez AMG, je sais \u00e0 quel point la barre est haute \u00e0 Affalterbach. Avec ce premier mod\u00e8le sur la nouvelle architecture AMG.EA, nous ne nous contentons pas d'y r\u00e9pondre, nous la d\u00e9pla\u00e7ons.\u201d<\/p>\n
