Mercedes-AMG's GT XX electric vehicle concept redefines endurance record standards

Mercedes-AMG's GT XX Prototype Sets Distance Records at Nardo Test Facility

In a remarkable display of endurance and performance, Mercedes-AMG's GT XX prototype has broken several distance records at the Nardo test facility in Italy. The prototype, which completed the equivalent of Earth's 24,907-mile (40,074 km) perimeter in just seven days, 13 hours, and 24 minutes, has been making headlines in the automotive world.

During an eight-day test program, the GT XX prototype set new endurance highs at intervals ranging from 12 hours to seven days. One of its most notable achievements was the 24-hour distance record, where it covered an impressive 5480 kilometers, averaging 299 km/h. This eclipsed the previous record set by XPeng by 1518 kilometers.

The GT XX prototype's impressive performance can be attributed to its advanced technology. Its electric drivetrain is built on AMG's forthcoming AMG.EA 800-volt platform and consists of three motors—two axial-flux units at the rear and one at the front. The power is supplied by a 114 kWh cylindrical-cell battery, which is cooled by a unique oil-immersion system. This cooling system was developed with input from Mercedes-AMG's Formula 1 powertrain division.

The GT XX prototype's battery setup enables extremely high charging speeds, with a theoretical 400 km top-up in around five minutes. This rapid charging capability, combined with its impressive distance-covering ability, makes the GT XX prototype a formidable force in the world of electric supercars.

Two prototypes were used in the record-breaking test, supported by 17 professional drivers including Mercedes-AMG Formula 1 racer George Russell. Crews rotated in eight-hour shifts, with more than 100 engineers, logistics staff, and a mission-control team at AMG's German headquarters coordinating the effort.

The achievements of the GT XX prototype point directly to AMG's production future. The next-generation AMG GT 4-Door Coupe expected in late 2026 is expected to inherit the drivetrain of the GT XX prototype, targeting 0-100 km/h in under 2.5 seconds and a top speed of 360 km/h.

In the recent weeks, Tesla, Mercedes-AMG, and Porsche have attempted to break records at Dauerfahrten with electric super-limousines on the Nardo-Testgelände in Italy. The result of the Mercedes-AMG GT XX-Prototyps was particularly noteworthy, as it achieved a top speed of over 300 km/h and displayed extraordinary reliability and performance under intense loading conditions. Other recent attempts include Xiaomi's YU7 Max (3944 km) and Mercedes-Benz's own CLA electric prototype (3717 km).

The GT XX prototype's record-breaking performance is a testament to Mercedes-AMG's commitment to innovation and performance in the electric vehicle market. As the automotive industry continues to move towards electric powertrains, it is clear that Mercedes-AMG is at the forefront of this transition.
