With the CONCEPT AMG GT XX, Mercedes-AMG sets new benchmarks and continues the brand’s decades-long tradition of relentlessly pushing the boundaries of automotive engineering. From historic motorsport triumphs to legendary records on race and test tracks, the performance brand from Affalterbach has always stood for the pursuit of ultimate performance. Mercedes-AMG reaffirmed this commitment just last year with the lap record of the Mercedes‑AMG ONE on the Nürburgring-Nordschleife. Since October 2022, the hypercar has remained the fastest production vehicle ever on the iconic circuit – having even beaten its own record.
Now, the CONCEPT AMG GT XX builds on this proud legacy and delivers a powerful demonstration of the superior performance of the upcoming high-performance AMG.EA architecture. The technology pioneer is powered by revolutionary drivetrain technologies set to enter production next year with AMG.EA. Featuring three axial-flux motors and a directly cooled high-performance battery, the concept vehicle promises a new dimension of power and endurance. Mercedes-AMG has now proven this under extreme conditions – the ultimate test evoking the record runs of the past, powered by the technology of tomorrow.
On the legendary high-speed test track in Nardò, Italy – a site where the world’s fastest cars have been put to the test for decades – the CONCEPT AMG GT XX broke a total of 25 long-distance records. Among them was the record for the greatest distance ever covered by an electric vehicle within 24 hours. The previous record was under 4,000 km (2,485 mi), which the CONCEPT AMG GT XX has far surpassed. The technology platform traveled 5,479 km (3,404 mi) in 24 hours – 1,518 km (943 mi) more or approximately 38 percent further than the previous record.
But this was just one of many records that the CONCEPT AMG GT XX secured with a commanding lead. The technology pioneer’s extreme test lasted far longer than 24 hours. The goal: to drive “around the world in eight days” – a mission to prove the superior long-distance performance of the AMG electric drivetrain. The name of the challenge? A nod to Jules Verne’s “Around the World in 80 Days.”
The record run followed an exceptionally demanding schedule. The greatest strain on motors and battery occurs under high-load driving and high-speed charging cycles. To simulate this scenario repeatedly, the CONCEPT AMG GT XX was tasked with covering as long of a distance as possible in the shortest possible time. Drivers maintained a constant speed of 300 km/h (186 mph), stopping only to recharge at power levels averaging around 850 kW – far beyond what today’s charging infrastructure can provide. This once again underscores the future-proof capabilities of this production-ready drivetrain. After each charging stop, the vehicle accelerated back to 300 km/h (186 mph) – over and over, day and night, for eight relentless days.
Although capable of significantly higher speeds, the vehicle’s pace was deliberately set by the engineers based on extensive simulations. According to these analyses, the 300-km/h (186-mph) speed offered the optimal balance between track speed and charging stops, delivering the fastest overall time.
In the early morning of August 25, 2025, the moment finally arrived. The distance of 40,075 km (24,901 mi) was covered in exactly 7 days, 13 hours, 24 minutes and 7 seconds – beating its own target of eight days by a wide margin. Along the way, the CONCEPT AMG GT XX set a number of additional performance records (see table below) and even pushed on to reach yet another milestone at 25,000 miles.
It wasn’t just one CONCEPT AMG GT XX that mastered the extremely demanding marathon program – but two. Both vehicles set off simultaneously on the record-breaking drive and delivered a compelling demonstration of endurance. After more than seven and a half days of operation and a full circumnavigation of the globe each, they crossed the finish line just 25 km (15.5 mi) apart – the equivalent of barely two laps on the Nardò proving ground. Completing this around-the-world challenge twice within eight days underscores the exceptional long-term performance capability of the powertrain.
The relentless program required 3,177 laps of the 12.68‑km (7.88-mi) Nardò circuit. Experienced race drivers completed two‑hour shifts in the seemingly endless round-the-clock race. On average, the CONCEPT AMG GT XX drove more than 5,300 km (3,293 mi) per day. Conditions were also far from favorable. During the day, ambient temperatures rose up to 95 degrees Fahrenheit (35 degrees Celsius) in the shade – climbing even higher under direct sunlight on the exposed track. Yet the car’s revolutionary powertrain delivered flawless performance throughout.
The test was not only a feat of technology, but also of teamwork. From the pit crew handling charging and tire changes, to the round-the-clock provision of fire and rescue services to the remote support room in Affalterbach, which was permanently connected to Nardò via remote diagnostics. External specialists – including tire supplier Michelin and charging station specialist Alpitronic – rounded off the expert crew.
“Mercedes-AMG and Formula 1 stand for innovation, intense competition, and pushing the boundaries of what is technically possible. Our company’s powertrains achieved groundbreaking successes in the very first road races in automotive history more than 120 years ago and have set benchmarks for decades. In the 1970s and 1980s, Mercedes‑Benz was a regular guest here at Nardò, setting numerous international speed and track records – most notably with the C111 as a visionary technology program. Back then, we demonstrated the performance capabilities of innovative diesel and gasoline powertrains. Now, with the CONCEPT AMG GT XX technology program, we are entering a new dimension of performance – this time with fully electric drive. The goal is to redefine the limits of what is technically possible in the age of electric drives. So what could be more fitting than to chase records once again? Our mission: to redefine the very standards of performance with groundbreaking technologies and innovations. The motivation and dedication of the cross-functional team from Mercedes-AMG, Mercedes-Benz, Mercedes-Benz Mobility and our F1 engine experts at Mercedes-AMG High Performance Powertrains throughout the entire preparation phase were boundless. I am immensely proud of the unprecedented achievement of the entire team in this unique record drive.”
Markus Schäfer, Member of the Board of Management of Mercedes‑Benz Group AG. Chief Technology Officer, Development & Purchasing
“An AMG has always been defined by its drivetrain. In the electric world, too, our drive system must be convincing across the board. That’s why we’re the first manufacturer to use axial flux motors and directly cooled batteries in fully electric models. We have now impressively demonstrated how superior these technologies are. Enormous performance and extremely fast charging were always available and made these records possible. For customers of our future electric models, this means they will get a genuine AMG – no ifs, ands or buts. My heartfelt thanks go to the entire team – we’re delighted that we can also count on the best team in the automotive industry when it comes to electric performance.”
Michael Schiebe, Chairman of the Board of Management of Mercedes‑AMG GmbH and
Head of Mercedes‑Benz G‑Class & Mercedes‑Maybach divisions at Mercedes‑Maybach
“As an F1 driver, I’m used to pushing technology to its absolute limits – the CONCEPT AMG GT XX really impressed me. The axial flux motors respond as immediately and precisely as a Formula 1 drivetrain, but with an endurance that I have only ever experienced with combustion engines. This technology will revolutionize the driving experience – both on the racetrack and on the road.”
George Russell, Mercedes‑AMG PETRONAS F1 team driver
A new dimension in electric endurance
The revolutionary drive concept with three innovative axial flux motors and a high-performance battery developed from scratch enabled a new dimension of continuous electric power and ultra-fast charging. This meant that the CONCEPT AMG GT XX could be pushed to its limits time and again during testing at Nardò, delivering a new level of continuous performance that was previously almost unthinkable in the world of electric vehicles. Even under extreme driving conditions, the batteries remained within an optimum temperature range – which not only ensured performance on the track but also enabled extremely fast charging.
Added to this are the axial flux motors, which are considerably more compact and lighter but above all significantly more powerful than conventional electric motors. The power density of axial flux motors is around three times higher. This enables top-level driving performance that can be reproduced very frequently and repeatedly.
Three axial flux motors and a directly cooled battery concept
The CONCEPT AMG GT XX generates a peak output of over 1,000 kW (>1,341 hp). This output is achieved by the three innovative motors integrated into high-performance electric drive units (HP.EDU) on the front and rear axles. The rear axle has two oil-cooled axial flux motors, which are combined with compact transmissions and one inverter each in a single housing. The front electric drive acts as a booster motor and is only activated when needed to provide additional power or traction.
Axial-flux motors offer enormous advantages over conventional electric motors. These are significantly more powerful while also being lighter and more compact. Its power density is roughly three times higher, while weighing less and requiring only one third of the installation space. The units also deliver higher continuous output and greater torque.
The foundation for these groundbreaking motors was originally developed by British electric motor specialist YASA – a wholly owned subsidiary of Mercedes-Benz AG. But it was Mercedes-AMG that, in close collaboration with YASA, elevated this concept to an entirely new level of performance for series production in the new AMG.EA platform.
The high-performance battery is a completely new development from Affalterbach, inspired by Formula 1®. It enables a high power output that can be called up frequently and repeatedly, contributing to the vehicle’s outstanding overall performance. The battery uses newly developed cylindrical NCMA cells, which offer efficient cooling and a high energy density of over 300 Wh/kg thanks to the cells’ tall and narrow format. The laser-welded aluminum cell housing improves electrical and thermal conductivity and contributes to the battery’s robust and long-lasting performance.
The battery cells are intelligently and directly cooled by an electrically non-conductive oil, which optimally regulates the temperature of each of the more than 3,000 cells. This cooling ensures even heat dissipation and supports the high continuous power potential of the energy storage system. Voltage of over 800 volts reduces weight through lighter cables and shortens charging times, while intelligent thermal management precisely controls the temperature of the cells to ensure maximum performance even under extreme conditions.
This enables the CONCEPT AMG GT XX to charge extremely quickly. The technology platform charges at over 850 kW across a wide range of the charging curve. In just five minutes, it can recharge enough energy for a range of around 400 kilometers (WLTP)1 – equivalent to the distance from Nardò to Naples.

The CONCEPT AMG GT XX is a pioneering technology program that offers an impressive look into a forthcoming four-door series-production sports car from Mercedes‑AMG. With three axial flux motors and a high performance battery developed from scratch, the brand from Affalterbach presents a revolutionary drive concept that enables a whole new dimension of performance. It includes an abundance of technical innovations earmarked for use in the subsequent series-production models based on the high performance AMG Electric Architecture (AMG.EA).
Revolutionary drivetrain: high performance axial flux motors and new battery technology
In the nearly 60-year history of the Mercedes-Benz performance and sports car brand, the powertrain has always been the heart of the vehicle, bar none. The team at Affalterbach are continuing this tradition with the CONCEPT AMG GT XX, which introduces a revolutionary drive technology in the form of the innovative axial flux motor.
Its technological underpinnings were originally developed by British electric motor specialist YASA – a wholly owned subsidiary of Mercedes-Benz AG. For its application in the CONCEPT AMG GT XX and subsequently in series production, the concept was taken to a whole new level of performance. This was achieved in a collaboration between Mercedes-AMG and the technology experts from YASA. The performance specialists from Affalterbach have also developed the software for the operating strategy, which optimally utilizes the high performance of the motors. The innovative electric motors enable high output from an extremely compact package and enter series production at Mercedes-AMG in 2026.
Thanks to a peak output of over 1,341 hp, the CONCEPT AMG GT XX can reach speeds of more than 223 mph. In combination with the new high performance battery, the three axial flux motors attain a completely new level, particularly in respect of continuous output. This allows the CONCEPT AMG GT XX to be pushed to its limits repeatedly, offering a new level of continuous performance that was almost unthinkable in the world of electric mobility – until now. The battery remains in an optimal temperature range even during intense driving, enabling both performance on the road and extremely fast charging. The concept vehicle can charge to approximately 400 kilometers (WLTP)2 of range in around five minutes, which is roughly equivalent to the distance from Affalterbach to Spa-Francorchamps. After fast charging, the vehicle can immediately deliver full output again – an unprecedented capability.
Significant benefits in power profile, weight and packaging
Axial flux motors offer many benefits: they are significantly more compact, lighter and, above all, more powerful than conventional electric motors (radial flux motors). The power density of axial flux motors is around three times that of conventional electric motors. At the same time, the innovative motors are around two-thirds lighter and are just one third of the size. This compact motor design offers more flexibility when it comes to drivetrain packaging. Compared with conventional electric motors, the innovative drive delivers a considerably higher sustained power output as well as higher torque. This translates into the highest levels of performance, reproduceable again and again with great frequency.
In an axial flux motor, the electromagnetic flux runs parallel to the motor’s axis of rotation. In a conventional electric motor, it runs perpendicular to the axis of rotation. The large components in an axial flux motor are shaped like slim discs. The stator is positioned between two rotors on the left and right sides. This layout of stator and rotors enables optimum power transmission to the rotors through the electric field generated by the stator. In the CONCEPT AMG GT XX, this combination is barely 3.5 inches wide. Each of the two motors at the rear are around just 3.1 inches wide.
Compelling power: more than 1,341 hp peak output
No fewer than three of these innovative electric motors guarantee outstanding system power in the CONCEPT AMG GT XX with a peak output of more than 1,341 hp. The motors are packaged into two High Performance Electric Drive Units (HP.EDUs) – one at the front and one at the rear. The HP.EDU at the rear has two axial flux motors, each equipped with a compact planetary gearset and one inverter, in a single casing. The motors and transmissions are oil cooled. To save even more space, the necessary pump control unit with hydraulic pumps and suction filters is integrated into the HP.EDU. The two inverters (one per motor) are water cooled. The material properties of silicon carbide offer multiple benefits for demanding applications requiring high voltages, high current, high temperatures and high heat conductivity.
The front HP.EDU comprises one axial flux motor, a spur-gear transmission and an inverter. The front electric drive functions as a booster motor for when additional power or traction is required at the front wheels. When the front electric motor is not needed for the driving situation, a Disconnect Unit (DCU) decouples it. During acceleration and recuperation, the DCU engages for optimal performance. During steady driving, low load and coasting, it disengages again, reducing unnecessary drag losses and increasing efficiency.
Innovative processes for axial flux motor production
The axial flux motors are produced at the Mercedes‑Benz plant in the Marienfelde area of Berlin. It has been an important part of the global Mercedes‑Benz Powertrain production network for decades and handles the production of various drive components. Axial flux motor production involves approximately 100 processes, of which roughly 65 are new for Mercedes‑Benz and 35 are world firsts. These include new forms of laser technology combined with innovative joining processes and artificial intelligence. These new production processes were developed largely in-house by Mercedes‑Benz, and the innovations led to more than 30 patent applications. All this underscores Berlin-Marienfelde’s leading role worldwide in production-process innovations.
Inspired by Formula 1, developed in Affalterbach: High Performance Electric Battery
The high voltage battery in the CONCEPT AMG GT XX is a completely new development. It benefits from all the experience from the AMG ONE and Formula 1® as well as the knowledge of the best engineers from Mercedes‑AMG in Affalterbach and Mercedes‑AMG High Performance Powertrains (HPP) in Brixworth (UK).
The High Performance Electric Battery (HP.EB) delivers a high power output with exceptional repeatability, guaranteeing the vehicle’s outstanding overall performance. This is paired with rapid energy absorption and high power density. Contributing to the high system performance are three main aspects: new battery cell developments, direct cooling of the cells and high voltage.
New battery cells developed to meet exceptionally high performance demands
The battery features a completely new cell design, developed for exceptionally high performance. The CONCEPT AMG GT XX uses cylindrical cells that are remarkably tall and slim. This format delivers many benefits for cell cooling. The narrow diameter means the distance from the cell core to the casing is particularly small. This enables rapid dissipation of heat generated under load and ensures each individual cell is kept within the optimum temperature window.
Also new is the laser-welded aluminum cell housing. It is lighter than the steel housings typically used and has considerably better electrical and heat conductivity. This offers benefits in the targeted thermal control of the cells – with faster cooling or heating on demand.
The cells use the full-tab configuration which means the entire surface of the cell tail is electrically and thermally connected to the pole. This enables a significant reduction in the cell’s internal resistance, which facilitates high charging and discharging power. Furthermore, full-tab battery cells are especially robust and also function reliably under demanding load conditions.
A further innovation is the optimized operating window. The full-tab cells underwent detailed measurement and testing in advance using a special reference electrode and core temperature sensors. The data gathered was implemented in the software for the battery management system. This enables better modelling of cell behavior and thus a significant increase of charging power at higher temperatures.
The cell chemistry was developed specifically for the CONCEPT AMG GT XX. It is based on NCMA (nickel/ /cobalt/manganese/aluminum) in the cathode and an anode with silicon content. This offers a combination of high energy density of 300 Wh/kg (740 Wh/l on cell level), powerful charging performance and long lifespan that is thus far unique.
Overall, the combination of a tall, narrow cell format, aluminum housing, full-tab technology and NCMA chemistry lays the foundation for high performance within the individual battery cells, especially in terms of sustained power delivery.
Intelligent direct cooling of the battery cells
The individual cells are packaged into laser-welded plastic modules. Direct cell cooling is integrated into the plastic modules to ensure optimum heat dissipation. A high tech coolant based on an electrically non-conductive oil flows around each individual cell to maintain the optimum temperature. The coolant flows through coolant channels in the modules, which are optimized for equal cooling of all the cells. A special piping system ensures even distribution of the cooling oil. There are more than 3,000 cells in the CONCEPT AMG GT XX.
The lithium-ion battery has a high voltage of more than 800 volts, which also contributes to overall performance. The benefits of the high voltage are lower weight due to the lighter cables, higher continuous power output and shorter battery charging times. Charge losses via the charging cable are also considerably less.
Temperature control for short charging times, minimal aging and long lifespan
Temperature control of the HP.EB is intelligently configured for different driving situations. Heating it to the optimum temperature window is fast and precise. Maximum power is delivered across a wide temperature band.
The operating strategy is programed to facilitate maximum performance from the battery, followed by a reduction in temperature through the direct cooling system. Intelligent heat management controls the temperature of the coolant for each cell module at precisely the pre-determined value as required (on-demand cooling). As a result, the battery retains its high power reserves, even during dynamic driving with frequent acceleration (battery discharged) and deceleration (battery charged via recuperation). This effective direct cooling in combination with the cell enables the high level of sustained power density.
Fast charging performance
The charging performance likewise sets new benchmarks – again due to direct cooling. This pairs with optimized thermal management of the cells and power lines during charging. The CONCEPT AMG GT XX achieves a very high average charging power of more than 850 kW at 1,000 amps over a wide range of the charging curve.
To match the vehicle’s charging performance, the Mercedes‑Benz Charging Unit worked in close collaboration with partner Alpitronic, the European market leader in high power charging. Alpitronic has developed a prototype charging station. It is the first charging station able to transmit such a high current via a standard CCS cable.
For the future series-production models, Mercedes-Benz will expand the infrastructure of its own Mercedes‑Benz Charging Network with the next generation of high performance charging stations. Customers will benefit from extremely fast charging times.
Body structure and battery housing: safety is the number one priority
The body structure of the CONCEPT AMG GT XX is based on the new AMG.EA architecture and is completely new. The intelligent material matrix consisting of aluminum, steel and fiber composite materials combines the exceptional rigidity that is a hallmark of AMG with low weight. Optimized material cross-sections and component design create space for the advanced technology and sophisticated powertrain.
The high voltage battery is centrally integrated into the structure of the electric skateboard platform. Its protective housing encases the cell modules, all switch components and the Battery Management System (BMS), which is likewise an exclusive in-house development by AMG. Defined lateral load paths combine high torsional rigidity with low weight and form the basis for a high level of crash safety.
The battery housing is part of the vehicle structure and integrated into the crash concept. Battery, high voltage (HV) cables and further HV components are configured and secured to fulfill Mercedes‑Benz’s high safety requirements.
Exterior: rebellious design with first-class aerodynamics
With its dynamic fastback, low slung hood and sharply raked windshield, the CONCEPT AMG GT XX is a statement of the brand’s signature sports car performance. This is further underscored by the striking color scheme in sunset beam orange.
The AMG specific front grille with ten vertical struts embodies a characteristic AMG design feature. However, it is further developed with its more oval and concave form. The Mercedes star is integrated into the middle. The slender, rectangular auxiliary headlights are recessed into the outer edges of the grille. The vertically arranged main headlights set innovative accents with low beam and high beam stacked one on top of the other.
A characteristic feature from motorsport is the two-part air outlets in the hood, each with two fins. These dissipate warm air from the horizontal cooling modules in the front of the vehicle and thus optimize the cooling air path. The front splitter extends far around the front of the car with an integrated air curtain function reaching up to the front wheel arches. The hood encapsulates the front as far as the wheel arches and emphasizes the distinctive sports car DNA of the CONCEPT AMG GT XX with two power domes.
The vehicle’s profile is defined by the low-slung front end, from which the fenders flare organically to frame the front wheels. The long, low greenhouse with double-bubble roof and three windows on each side rests on the muscular rear shoulders. The exterior mirrors are elevated on the front doors, in typical sports car fashion. The sill claddings have aerodynamic contours that extend into the rear wheel arches. Aerodynamic fine-tuning is also evident in the recessed door handles.
From a bird’s eye perspective, the streamlined greenhouse tapers rearward, allowing for particularly wide shoulders. The rear wheel arches also flow organically from the flanks. Another design element at the rear is the wide diffuser in exposed carbon, which sweeps deeply down at either side. Designed to ensure rear stability at high speeds, its form is reminiscent of the AMG ONE.
The vehicle body rests visually on a powerful floor structure that extends from the front splitter along the sill blades to the rear diffuser. The overhangs front and rear underscore the iconic overall proportions. The dynamic character is also expressed in the extravagant paintwork in sunset beam orange. Thanks to its special composition, the surfaces shimmer in the light like liquid metal.
The dynamic rear design, with its sharply angled aerodynamic edge and six circular deep red taillights, forms a unique vehicle identity. The lights and centrally positioned MBUX Fluid Light Panel are each framed by an elongated recess with conical sidewalls to create a particularly impressive sense of depth. The active airbrake is seamlessly integrated into the rear of the vehicle.
Aerodynamics: important factor for high performance, especially at high speeds
At 186 mph, approximately 83 percent of the drive energy is required to overcome drag. This shows how important efficient aerodynamics are in the high performance segment. The CONCEPT AMG GT XX shows what is technically possible. Aspects include the sporty flat shape, sharply raked windscreen, low-slung hood, angled side windows and the absence of a rear windshield.
The refinement continues into the underbody. A specially developed contour ensures aerodynamic balance, meaning optimum downforce paired with maximum efficiency. It generates the Venturi effect, which reduces lift at the rear without notably impacting the cd figure. This facilitates a lower rear and lessens the need for a pronounced rear spoiler. The intelligent aerodynamics offer a high level of handling stability in all areas up to the top speed of more than 223 mph.
The painstaking aerodynamic refinements reduce the drag coefficient and frontal area – which contributes to high speed performance as well as longer range at high speeds. Despite the wide high performance tires, the drag coefficient is cd=0.198.
Aerodynamics also support other cooling functions
In addition to the large air outlets in the front hood, the CONCEPT AMG GT XX utilizes a passive cooling plate located at the front of the underbody, using the airflow beneath the car for cooling. Another feature is the active air control system AIRPANEL, known from the AMG GT series models and further developed here. This allows for the best compromise between cooling and aerodynamic drag. The system manages airflow in multiple stages according to cooling requirements, operating with louvers hidden behind the air intake in the front bumper. Normally, these are closed, reducing drag and directing air towards the underbody. When certain temperatures at predefined components are reached and cooling demand is particularly high, the louvers open in multiple stages, allowing cooling air to flow to the heat exchangers as needed.
Interior design: purist cockpit with exposed technology
The interior of the CONCEPT AMG GT XX is reduced to the essentials, like a race car, while offering a luxurious look and feel. The interior is immersed almost completely in black. Silver and orange accents emphasize the visually minimalist focus on technical elements. Taking center stage are the high quality materials with different textures that feel as good as they look. Visible body structures and interior components inspired by high voltage cables create a close connection to motorsport, the origin of AMG. The purist cockpit, with two integrated screens, is fully focused on driving. The vehicle and all its instruments are controlled via two large LCD displays: 10.25-inch instrument cluster and the 14-inch multimedia touchscreen. The displays are ergonomically angled towards the driver and have a seamless glass look.
The steering wheel is similar to that in the AMG ONE, with its almost rectangular shape and two horizontal struts on either side inspired by motorsport. The steering wheel paddles serve to control recuperation. A display on the steering column uses different color codes via eight LEDs to indicate the state of charge (blue), recuperation and current performance (red). In addition, there are two round AMG steering wheel buttons that control other functions and display the options with colored icons.
A particularly distinctive feature of the interior is the exposed extrusions of the body structure around the center console, with illuminated orange tubes. Their look creates an instinctive association with high voltage cables. Another striking feature is the design element in the center console, which takes the form of the AMG crest. The CONCEPT AMG GT XX thus expresses its top electric performance with high tech features machined from solid metal and illuminated.
There is likewise no cladding on the instrument panel. It references the look of a classic sports car engine block with the AMG logo machined into it and matte black finish. At the same time, the structural crossmember forms the upper part of the cockpit. The instrument panel is fully integrated and also contains the ducting for fresh air and cables. The vertical H-struts positioned centrally beneath it combine the cockpit substructure and center console mount in one module. Consistent implementation of the extrusion structure represents an overarching design theme.
Sculpturally minimalist door claddings are penetrated by an armrest featuring the extrusion structure. The subtly backlit racing perforations in the door panels provide a second-read effect that breaks up the black.
To save weight, the individually formed carbon fiber bucket seats in the rear, including the cushions, are completely integrated into the car’s rear bulkhead. The roof has no headliner, which saves weight and exposes the carbon fiber structure. The door panels with lightweight tubes and orange closing loops complete the innovative and sporty overall look. The checkered flag design of the color-backlit fabric is a further reference to motorsport. The fastening points on the doors are clad with small buttons of machined aluminum. These display the AMG crest and are accented with the exterior paint color.
The floor covering is made of 100-percent recycled materials. Its sporty design with checkered flag elements again references motorsport.
Emotional and intuitive MBUX
The user interface and the Mercedes‑Benz User Experience (MBUX) in the CONCEPT AMG GT XX are emotional and intuitive to use. It is based on the in-house Mercedes‑Benz Operating System (MB.OS). The deeply integrated chip-to-cloud architecture networks and controls all domains and functions. For the CONCEPT AMG GT XX, the UI/UX design team in Sindelfingen designed an exclusive interface that shows the highlights of the electric drive system, including the High Performance Electric Battery as a video animation on the multimedia display.
High level of traction and directional stability: AMG Performance 4MATIC+ fully variable all-wheel drive
The CONCEPT AMG GT XX delivers its power to the road with the AMG Performance 4MATIC+ all-wheel drive. Completely decoupled from one another, the three electric motors allow fully variable torque distribution to the front and rear wheels. This enables a high level of traction and driving safety as well as greater efficiency. The transition between rear-wheel and all-wheel drive occurs continuously based on an ingenious matrix that integrates the control algorithms into the entire vehicle architecture.
- Multiple innovations for the sports car of the future
- The CONCEPT AMG GT XX not only sets new standards in performance but is also pioneering the future of the sports car with many other innovations inside and out. Highlights include luminescent areas of paintwork along its flanks, speakers integrated into the front headlights and the MBUX Fluid Light Panel at the rear. The interior features innovative biotechnology-based materials as well as ergonomic 3D seat pads.
MBUX Fluid Light Paint
The exterior of the CONCEPT AMG GT XX shines with luminescent paint segments. This allows special effects by night on defined areas of the vehicle body. To achieve this, the experts from research and development use electroluminescence technology: special color pigments emit light in response to an alternating current. This results in brightly glowing paint that is clearly noticeable in the dark. The paint is built up in several electrically conductive and insulating layers. Mercedes‑AMG has already successfully tested this paint on a GT3 race car at the 24-hour race on the Nürburgring. On the CONCEPT AMG GT XX, the cladding on the longitudinal beams is highlighted in color with luminescent segments referencing the AMG logo. However, the paintwork is not only for visual effect at night. During the charging process, it also serves as a means of communication and visually enhances the experience. The segments switch off one after the other – and once they are all off, the CONCEPT AMG GT XX is ready to go and gives yet another signal as it drives off.
Speakers in the headlights
Another innovation combines light and sound in a new form. The exterior speakers for emitting driving sounds are integrated into the front headlights for the first time in the CONCEPT AMG GT XX. These use the headlight housing as a speaker enclosure. This integration saves space, reduces weight and enables new sound variants. In addition, the speakers also serve as signals for pedestrian protection. Another feature is the passive membrane technology in the soundbar. It enables low frequency and more powerful bass reproduction, as it makes better use of the available installation space.
Communication with the outside world via MBUX Fluid Light Panel at the rear
The innovative MBUX Fluid Light Panel at the rear of the vehicle features more than 700 freely programmable RGB LEDs. The illumination enables active communication with the outside world. The front side has been media blasted to achieve perfect homogeneity for the backlighting of each pixel. The innovative internal structure prevents light scattering between the pixels and ensures outstanding image quality. When turned off, the panel features an elegant 3D pixel look. When turned on, a special effect is created through the unexpected light staging.
Thanks to an intelligent software solution, information from the vehicle can be displayed in real time for the first time as text or animation. It can show a variety of content, such as a digital AMG logo or the current charging process.
Interior innovations: alternative materials for the sports car of the future
The interior of the CONCEPT AMG GT XX also points to the future with LABFIBER materials. This refers to innovative materials based on biotechnology. The technology program features alternatives to leather and silk, both produced with the help of biotechnology.
Biotechnology-based leather alternative derived from recycled GT3 racing tires
The LABFIBER Biotech Leather Alternative was developed and manufactured with the help of modern biotechnology. It is the result of an exclusive and intensive development partnership with U.S. bio-design startup Modern Meadow. This collaboration leverages the next generation materials technology from Modern Meadow to further develop the LABFIBER Biotech Leather Alternative for series production and set new standards in vehicle interiors. The use of this innovative material in the CONCEPT AMG GT XX is a first in the automotive sector. It consists of a combination of recycled rubber, vegetable proteins and biopolymers. LABFIBER Biotech Leather Alternative mimics the most important characteristics of the collagens found in leather. The new material therefore offers a level of design freedom equivalent to that of conventional leather. The leather alternative can be produced with different surface finishes such as nubuck, full grain leather or suede as well as a variety of colors and textures.
Using a chemical recycling process, pyrolysis oil is first produced using old tires and certified biomethane from agricultural waste. These are then processed into plastic fibers in accordance with the mass balance method. These microfibers, in turn, are used to create a semi-finished product to which vegetable proteins and bio-based polymers are added. In contrast to artificial leather, this innovative combination of materials has the same structure as genuine leather and can also be processed like genuine leather in retanning processes. As a result, it has the same high quality look and feel as materials like nubuck leather as well as natural aging properties. The bio-design means the LABFIBER Biotech Leather Alternative is breathable and waterproof as well as being lighter than real leather. Its maximum tensile strength is also twice as high as that of genuine leather, meaning it is very robust. And because of its low thermal conductivity, the material does not heat up quickly, even in summer. The content derived from recycled plastic can be fully recycled.
For the application in the CONCEPT AMG GT XX, Mercedes-AMG uses pyrolysis oil produced from racing tires that were actually used in competition on AMG GT3 customer racing cars. One scrap tire provides the basis for approximately 43 square feet of new LABFIBER Biotech Leather Alternative. The black seat pads of the bucket seats are covered with the Nappa-look variant. The innovative material is configured for closing material loops. It embraces complete chemical recycling, whereby the end product (LABFIBER Biotech Leather Alternative) is of a higher value than the starting material (scrap tires) – a perfect case of upcycling.
Another innovative material in the CONCEPT AMG GT XX is the biotechnology-based LABFIBER Biotech Silk Alternative. This starts with silk proteins produced by genetically modified bacteria. These proteins are refined into a shiny, silky yarn using a wet spinning process. The synthetic silk has the same functional properties as animal-based silk. However, it is 100 percent biodegradable, very light and at the same time high strength. In the CONCEPT AMG GT XX, the door handles are made from this innovative silk alternative, produced in orange to match the exterior.
Seats: innovative tailor-made ergonomics from the 3D printer
The front bucket seats are based on carbon fiber racing shells with ventilation openings and integrated headrests. The new 3D-printed seat pads with an open 3D structure offer a new level of customization with optimized ergonomics and are easy to swap out. This creates a comfortable seat structure adapted specifically to each user. The seat pads are covered with the innovative LABFIBER Biotechnological Leather Alternative in Pearl Black. The idea behind the seat pads also comes from motorsport. Each driver has a set of individual seat cushions that can be quickly swapped out – for example during driver changes in endurance races. In the CONCEPT AMG GT XX, the individually designed seat pads were created using 3D printing technology. The ergonomic data is provided by a body scan of the respective individual. The six-point safety harnesses underscore the sporty design.
Patented world first: active, intelligent, electronically controlled Aero Wheel with moving aero blades
A special highlight is the active Aero Wheel that optimizes brake cooling, aerodynamic efficiency and maximum range. The 21-inch five-spoke forged aluminum wheel is equipped with five movable elements. When closely positioned, the blades close flush to the wheel, thereby reducing drag. This improves range and reduces energy consumption.
A control unit located in the vehicle monitors and controls, among other things, the function of the brake system. It detects the need for increased brake cooling. When it sends a signal to the actuators, these deploy and actively open the blades, which opens an annulus on the outer wheel rim. Supported by the radial louvers on the inner side of the aero blades, cooling air is pumped through the wheel to the brake and back out again. Increasing the air mass flow in this way achieves significantly more efficient brake cooling. The active removal of air from the wheel arch, which interacts aerodynamically with the underbody, also has a positive influence on the vehicle’s aerodynamic downforce.
Integrated in the hub of each wheel is a central actuator that is straightforward to install and remove. This actuator moves the aero blades. Each actuator is an autonomous unit that uses the spinning wheel to produce its own electrical energy via a mini-generator. The actuator uses Bluetooth to communicate wirelessly with the control unit in the vehicle. Paired with an integrated high performance battery, it can generate and store enough energy for up to 200 blade movements, thus ensuring optimal brake cooling at all times.
