AMG C590

AMG présentera en Juin (ou Juillet ?) un nouvelle berline BEV hautes performances basée sur une plateforme spécifique baptisée AMG.EA. Moteurs à flux axial, 100kWh, probablement autour voire plus de 1000ch, ils semblent viser Taycan GT et Lucid Sapphire.

Si AMG sort enfin une vraie BEV conçue maison sur plateforme AMG.EA, ça marque clairement la fin du "badge engineering" sur base EQS. Là, on parle de moteurs à flux axial (donc légers, compacts, très efficaces à haut régime), d’un pack autour de 100 kWh et surtout d’une cavalerie probablement à 4 chiffres. AMG ne cache plus qu’ils veulent concurrencer directement le Taycan Turbo GT ou même la Lucid Air Sapphire. Autant dire qu’ils visent le sommet.

Curieux de voir xa.

- The CONCEPT AMG GT XX features three revolutionary axial flux motors that together produce more than 1,000 kW (1,360 hp). That’s despite each one being around two-thirds smaller and lighter than a traditional electric motor. In fact, they are so compact that each motor would almost fit inside a pizza box.

- The electric motors are packaged into High Performance Electric Drive Units (HP.EDUs) front and rear, with one motor in the front drive unit and two in the rear. Each motor assembly features its own silicon-carbide DC/AC inverter. One of the hardest substances on earth – with an official rating just below diamonds –
silicon carbide is extremely tough and heat-resistant, which is why it’s also used in rocket engines and as protective armour on space telescopes.

- Copper coils are an integral part of an electric motor, but the key is to pack as much of the material as possible into a very tight space. That’s why the copper wire used in the innovative axial flux motor that powers the Concept AMG GT XX isn’t round, but rectangular. Think of it like pasta: when serving up a hearty Ragù, Italians swap spaghetti for tagliatelle, because its flatter, broader surface carries more of the sauce. The rectangle-shaped wire is then precisely bent and wound into a specific radius, allowing for more copper per slot in the stator. The result is better power density and thermal efficiency – and not a tomato-stained shirt in sight.



- Production of the axial flux motor alone involves around 100 production processes, 65 of which are new to Mercedes-Benz and 35 of which are world firsts. This staggering number includes innovative bonding processes and groundbreaking use of artificial intelligence – as well as some serious attention to detail.
That’s because to connect the stator, the surface has to be 100 per cent dust- and grease-free, so an AIsupported vision system is used, combining powerful sensors and cameras, to place ‘virtual protection zones’ over sensitive areas. It’s a little bit like masking your switches and door frames before painting your
walls, but with a level of accuracy that’s impossible for the human brain to handle. A laser is then used to clean the material with pinpoint accuracy



- The CONCEPT AMG GT XX has a drag coefficient of 0.198 – about the same as a soaring eagle. Very few things in nature have a more aerodynamic shape – except for a peregrine falcon in full dive mode or a dolphin at full speed. This slipstreamed design increases driving range while also maximising handling
stability in all areas up to a top speed of more than 360 km/h, without the need for active aero elements.

- It’s not just the headlights that shine – sections of the car’s bodywork also light up with the MBUX Fluid Light Paint. This electroluminescent technology works by applying a small current to electrically conductive paint layers. As well as producing a cool visual effect at night, this electric paint also signals when the car is slowing to a standstill, when it’s ready to charge and how far charging has progressed. Such paint’s properties also make it well suited to covert operations and it has even been used for experimental aircraft markings. Useful for slipping under the radar…

- Like many EVs, the CONCEPT AMG GT XX has external speakers to emit the driving sound and for pedestrian protection, but for the first time ever they are integrated into the headlight housings. These innovative speakers save space, reduce weight and enable new sound effects. They also feature passive
membrane tech, which uses air pressure to produce deep bass and low frequency sounds without any electrical input.

- For the first time in the automotive world, the CONCEPT AMG GT XX uses an innovative material called LABFIBER Biotech Leather Alternative. Produced with the latest biotechnology, it has the same look and feel as genuine leather yet it’s twice as strong and, with low thermal conductivity, it doesn’t heat up as
quickly – even in summer. Its clever combination of materials includes vegetable proteins, bio-based polymers and, best of all, a recycled AMG GT3 racing tyre. So our motorsport DNA doesn’t just put you inthe driver’s seat – it is the driver’s seat.

- The carbon-fibre front bucket seats feature ergonomic pads created using a 3D printing process and are tailored specifically to each driver. The idea comes from the racing world, where individual seat pads can be quickly swapped out for driver changes in endurance races. Every pad is finished with LABFIBER
Biotech Leather Alternative, which includes material from a recycled AMG GT3 tyre, meaning motorsport is literally part of the fabric of the car.









The CONCEPT AMG GT XX has a very high average charging power of more than 850 kW over a wide range of the charging curve. In just five minutes it can add 400 km of range – enough to drive from Affalterbach to Spa-Francorchamps (with enough range left for a few fast laps). To match that extreme charging performance, we worked closely with Alpitronic (a leader in high-power charging) on a prototype charging station – the first capable of transmitting such a high current via a standard CCS connector.




- In a patented world first, the CONCEPT AMG GT XX features wheels with active aero elements, providing the perfect answer to the conflict between brake cooling and aerodynamic efficiency. Each hub assembly has its own self-sufficient system comprising a generator, actuator and battery. When actuated, the
wheel’s five aeroblades create an opening around the edge of the rim and cooling air is pumped through to the brakes and back out again.

So exciting!
