Mercedes-AMG has broken a record: the Concept AMG GT XX electric car has achieved a charging speed of over one megawatt

In the world of electric cars, range plays a big role, but it’s charging speed that becomes the deciding factor on long trips. While owners are looking for rare 350kW stations, Mercedes-AMG has introduced a whole new level.
The company announced that its AMG GT XX concept car has achieved charging speeds in excess of one megawatt (1,000 kW), setting a new record. At a prototype station, the car produced a peak power output of 1,041 kW, reaching the megawatt mark just half a second after charging began. What’s more, the electric vehicle held above 1,000 kW for two and a half minutes. In one minute, it was able to transfer 17.3 kWh of energy, which is equivalent to 125 kilometers of travel. Thus, in four minutes, the car gained a range of about 500 km — almost like refueling a gasoline car.

AMG GT XX — is «a laboratory on wheels» where key technologies of the future AMG.EA platform are being tested. These include — axial electric motors and a revolutionary direct liquid-cooled battery. The unit operates at over 800 volts and incorporates more than 3,000 cylindrical NCMA cells, providing high energy density (over 300Wh/kg) and efficient cooling.

The secret to record-breaking charging lies in a unique system: electrically insulating oil circulates around each cell, preventing overheating and allowing the battery to safely take huge amounts of power.
For the record, Mercedes-AMG developed an experimental station together with the Mercedes-Benz Charging Unit and Alpitronic. It was based on the Megawatt Charging System (MCS), originally developed for electric trucks, which was adapted to the liquid-cooled CCS cable — the standard for electric passenger cars in Europe.

The experience gained will be used to create new charging stations. Mercedes plans to start installing superchargers in its company fleets in Europe and North America as early as 2026. This promises to drastically reduce waiting times for owners of the brand’s future electric cars.
