As part of its 50th anniversary, Mercedes-AMG is celebrating a successful past while also continuing to look forward. With the Mercedes-AMG GT Concept show car, the sports car and performance brand is giving an indication of the alternative drive configurations AMG is designing. This four-door coupe heralds a further extension of the AMG GT family, following the legacy of the SLS AMG and AMG GT, which were completely developed at AMG’s headquarters in Affalterbach.
The designation and fundamental design elements on the front and rear end denote the family affiliation to the AMG GT. The EQ Power+ badging on the mirror camera indicates the increased performance that can be expected from hybridization at AMG.
“With the Mercedes-AMG GT Concept, we are giving a preview of our third completely independently developed sports car and are extending the attractive AMG GT family to include a four-door variant.
The AMG GT Concept, like the AMG Hypercar, which we are presenting at the International Motor Show in Frankfurt, illustrates how we are defining performance of the future at AMG. Impressive driving dynamics coupled with high efficiency, resulting from an innovative drive system tailored specifically to the vehicle segment – that is ‘Future Performance’ made by AMG.
With our AMG GT Concept, that means a combination of an ultra-modern V8 gasoline engine and a high-performance electric motor, both intelligently networked with an extremely powerful yet lightweight battery concept.
This performance hybrid powertrain offers an impressive electric range and the opportunity to generate a system output of up to 805 horsepower in its last level of development, and covers the sprint from 0-60 mph in less than three seconds – which corresponds to the performance of a super sports car.”
– Tobias Moers, Chairman of the Board of Management of Mercedes-AMG
Design extérieur Mercedes-AMG GT Concept
The four-door sports car from Affalterbach will seamlessly continue the success story of the AMG GT. The dynamic fastback will be highly suitable for everyday use thanks to a large tailgate, luggage compartment and comfortable interior. The AMG GT Concept blends the high functionality of performance cars with the sportiness of AMG GT sports cars, and gives a sneak preview of the exterior design coming to the series production model.
With the aid of an unmistakable design idiom featuring a deeply drawn hood and powerfully raked windscreen, the AMG GT Concept is recognizable at first glance as a genuine AMG GT. The exterior design stands out with extremely muscular proportions and sensuous surface styling. The concept car represents the design philosophy of “Sensual Purity” with the added performance characteristics of AMG.
“The AMG GT Concept embodies the most extreme expression of our design idiom and underlines the autonomous profile of AMG as a performance brand. Through ideal proportions it creates a pure design with emphasis on its surfaces, featuring sensuous shapes, and is hot and cool at the same time.” – Gorden Wagener, Chief Design Officer, Daimler AG

… Eh attends ! revenons un instant sur la grille de calandre Panamericana colorés latéralement en rouge !
L’auto AMG est équipé de jante bicolores chromées et dorée en 22 pouces.
Du passage des roues …au châssis …moteur …il n’y qu’à scroller cette page web ! 😉
Châssis Mercedes-AMG GT Concept
Le concept est bâti à partir d’un châssis Mercedes Classe E. On retrouve donc une version 4 Matic+ de transmission intégrale permanente ici revue par AMG, incluant un différentiel arrière à répartition de couple.
…différentiel ?
Le différentiel dans sa forme basique a été inventé pour que les roues d’un véhicules puissent tourner à des vitesses différentes, afin de ne pas perturber le comportement d’un véhicule qui tourne.
L’innovation qu’apporte le différentiel actif – aussi appelé différentiel à répartition de couple – tient dans sa capacité à imposer une vitesse de rotation différente à chacune des roues motrices d’une voiture.
Généralement utilisé sur l’essieu arrière d’un véhicule à quatre roues motrices, ce système mécatronique va agir dès l’entrée du virage en fournissant un couple élevé à la roue extérieure pour aider à l’inscription dans la courbe.
En sortie de virage, le système – via son calculateur – contre le survirage et aide à la réaccelération en répartissant le couple principalement sur l’autre roue.
Outre le gain de confort et de plaisir de conduite, le différentiel actif apporte une tenue de route améliorée et contribue à une conduite plus sure.

On retrouve donc une version 4 Matic+ de transmission intégrale permanente revue par AMG, incluant un différentiel arrière à répartition de couple.
Donc avec ce différentiel arrière à répartition de couple et avec le moteur électrique qui agit en bonus uniquement sur les roues arrière
Le moteur électrique agit en bonus uniquement sur les roues arrière et peut assurer à lui seul le fonctionnement purement zéro émission.
Même possibilité de rouler uniquement avec le moteur thermique de 614 ch, ou, en tant qu’hybride, en combinant de manière optimale les ‘power suppliers’ des deux types de propulsion (V8 614 ch. +20 Kw) pour atteindre 805 ch.

Moteur Mercedes-AMG GT Concept
Sous le capot du Mercedes-AMG GT Concept, le bloc moteur dérivé du V8 4.0L bi-turbo de la GT de série est ici associé à un moteur électrique.
De quoi envoyer plus de 800 ch aux 4 roues motrices grâce à la technologie 4MATIC+. Le Power Unit civil s’inspire de la technologie utilisé en Formule 1 dénommée EQ Power+. Associé à l’essieu arrière, le bloc électrique peut servir de boost.
L’autonomie est dérivée là aussi de la Formule 1, le stockage d’énergie est plus puissant mais également plus compact et plus léger. Celle-ci se recharge en conduisant afin de disposer à tout moment du couple nécessaire.
On résume : V8 essence de 4.0L à l’avant et un moteur électrique de 20 kW à l’arrière, alimenté par un pack de batteries. …évolutives selon les attentes du client… ou les progrès de la technologie.
Leur alimentation (Power Supply) est fournie par le moteur thermique et par la récupération d’énergie au freinage. Ces techniques ‘Energy Recovery System’ (ERS) sont inspirées/développées par le département Formule 1 Mercedes-AMG HPP (High Performance Production) et déployé sur les modèles de séries.
Voilà si qql1 s’interroge sur à quoi sert la F1 pour les gens au quotidien !? On a là une démo de transfert de technologie.
Mercedes-AMG GT Concept – Driving Performance of the future
As part of its 50th anniversary Mercedes-AMG is this year celebrating not only the successful past and present; above all it is looking forward. With the show car Mercedes-AMG GT Concept the sports car and performance brand is giving an indication of the alternative drive configurations AMG is designing. Over and above this the four-door coupé heralds the further extension of the AMG GT family. The third model series after the SLS AMG and AMG GT is now being completely autonomously developed at the company’s headquarters in Affalterbach. The designation and fundamental design elements on the front and tail end denote the family affiliation to the AMG GT. The EQ Power+ identifier on the mirror cam indicates the increased performance that can be expected from hybridisation at AMG.
Advanced AMG GT characteristics
The Panamericana grille—with vertical ribs painted red on the sides—newly configured and extremely slim headlamps and side air gills with a dominant design in the front bumper are hallmark AMG GT design characteristics which have been advanced to a new level in order to express pure power.
The hood, reaching right to the wheel arches, underscores the AMG GT Concept’s sports car genes. This is also expressed by the eye-catching “Hot Red” paintwork featuring a finish that shimmers in the light like liquid metal thanks to a special formulation.
The Mercedes-AMG principle that fascination is always linked with function also applies to the AMG GT Concept. Proof of this includes moving radiator shutters in the center and side air intakes which improves both aerodynamic and thermal efficiency, and are inspired by the AIRPANEL active air control system found in the AMG GT R.
Rear assembly in hallmark AMG GT look
The wide rear assembly provides an unmistakable AMG GT look with extremely slim horizontal tail lamps and the shape of the tailgate. The taillamp also has new light technology, located beneath the three-dimensional lens of the rear lamps: a ribbed cooling module is integrated into the lens to guide waste heat away.
Further design elements at the rear end include a wide carbon-fiber diffuser curved downwards at the sides and a centrally arranged tailpipe reminiscent of the Mercedes-AMG GT R.
The crouched, dynamic greenhouse, with its steeply sloping roofline and slim layout of the frameless side windows, emphasizes the dynamic forwards thrust of the AMG GT Concept when seen from the side. The tapered side, broad rear shoulders and flared wheel arches reinforce the overall muscular expression. Exterior side mirrors on this concept are replaced with aerodynamically favorable miniature cameras, known as “mirror cams.” The roof, A-wing of the front spoilers, rear diffuser and side sill panels are finished in carbon fiber and make a distinct connection with motorsports.
Uniquely styled wheels allow for a good view of the AMG ceramic high-performance compound braking system. The brake calipers are painted in a bronze color and showcase ‘AMG Carbon Ceramic’ lettering.

‘Nano active fiber technology’ for daytime running lamps and tail lamps
With ‘nano active fiber technology’, Mercedes-AMG is presenting future-oriented daytime running lamps for the first time. This is produced by a special bright light system in a freely styled light cord. The three-dimensional illumination effect lends the AMG GT Concept an autonomous light signature, which is flanked by numerous further accents in the high-tech headlamp. Two tubular rod lights illuminate the road surface directly in front of the car and constitute the driving light together with a large LED main headlamp. A red AMG logo within the headlight denotes a special attention to detail. Overall, the front headlamp is a three-dimensional, multilayered, high-tech component which underscores the technical standards of the AMG GT Concept.
AMG Future Performance: forward-thinking hybrid drive system
The drive system of the AMG GT Concept represents a completely new development. In 2010, Mercedes-AMG proved that a super sports car with a battery/electric drive system can be realized with the SLS AMG Electric Drive. Additionally, Formula 1 driving dynamics and impressive efficiency are promised by the planned AMG Hypercar, which will give a sneak preview of the ultimate application of what is currently feasible with hybrid technology.
Following the AMG brand pledge ‘Driving Performance’, Mercedes-AMG will develop segment-specific hybrids in the future that will boast impressive performance and maximum efficiency.
Innovative combination of combustion engine and electric motor
After the W08 EQ Power+ Mercedes-AMG Petronas Motorsport Formula 1 car, the AMG GT Concept show car is the second AMG model to bear the new designation EQ Power+, a designation which all performance hybrids from Mercedes-AMG will be given in the future.
Mercedes-AMG Formula 1 engine infographic
The performance hybrid system combines a powerful Handcrafted AMG 4.0L V8 biturbo engine with an additional powerful electric motor, ensuring immediate response and offering extraordinarily high performance. A sprint from 0-60 mph takes the AMG GT Concept less than three seconds, demonstrating the performance of a super-sports car.
Maximum driving performance AMG’s primary focus on all projects and is why the AMG GT Concept has a balanced axle load distribution. The fully variable AMG performance 4MATIC+ all-wheel drive system is supported by an electric motor which drives the rear wheels directly and has the effect of an additional booster. Additionally, with torque vectoring, every wheel can be allocated torque individually resulting in a tangible increase in performance.
The electric drive unit
Three operating modes can be preselected via the electric drive unit: the AMG GT Concept can either drive purely electrically, purely with the combustion engine or with an optimal combination of both drive sources as a hybrid.
The exclusive AMG-developed hybrid components aim to facilitate a unique and dynamic “Driving Performance” experience. Power from two drive systems: performance operating strategy from Formula 1
The operating strategy of the AMG GT Concept is derived from the hybrid powerpack of the MERCEDES PETRONAS AMG Formula 1 racing car and was developed through cooperation with the development engineers at Mercedes-AMG HPP (High Performance Production). As in Formula 1, the battery is charged while the vehicle is driven in order to have the maximum amount of electrical power available for use at all times.

Scalable performance battery
The energy storage unit in the AMG GT Concept is more powerful than conventional hybrid batteries, but at the same time is more compact and lighter – further proof of the systematic way in which the AMG Lightweight Performance Strategy is being implemented. Charging of the battery while driving can occur via brake recuperation or with the aid of the combustion engine if the battery charge has dropped beneath a certain charge threshold.
On a modular basis this system is scalable upwards — the performance and capacity of the battery can be adjusted to meet specific requirements of customers or markets, for instance.
