Mercedes-AMG has set new long-distance performance records with its Concept AMG GT XX. At the Nardò high-speed test track in Italy, the vehicle covered 5,479 kilometres within 24 hours. The previous best for an electric car was below 4,000 kilometres.
AI Quick Summary
The Mercedes-AMG Concept GT XX set a new electric vehicle endurance record, covering 5,479 km in 24 hours at the Nardò test track. Two of the vehicles also drove a combined distance equal to Earth’s circumference (40,075 km) in just over a week. This feat was achieved with three axial-flux motors, a high-performance battery enabling 850 kW charging speeds, and consistent 300 km/h speeds.

The test programme extended beyond the one-day benchmark. Two Concept AMG GT XX cars were driven continuously for more than a week. Together, they completed a distance equal to the Earth’s circumference, totalling 40,075 kilometres in 7 days, 13 hours, 24 minutes, and 7 seconds.
Testing Conditions and Method
The cars were operated at a consistent speed of 300 km/h. Stops were made only for recharging, with average charging power around 850 kW. Each charging cycle was followed by immediate acceleration back to top speed.
In total, the programme required 3,177 laps of the 12.68-kilometre Nardò circuit. Drivers rotated in two-hour shifts. Daytime track temperatures reached 35°C, but the vehicles maintained full function throughout the schedule.
Technology Platform
The Concept AMG GT XX is powered by three axial-flux motors and a directly cooled high-performance battery. The system delivers peak output exceeding 1,000 kW (around 1,360 hp).
Axial-flux motors are lighter and more compact than conventional units, with three times higher power density. The battery uses cylindrical NCMA cells with a cooling system based on electrically non-conductive oil. This design supports high continuous output and rapid charging.
Charging tests showed the vehicle could recover energy for about 400 kilometres in five minutes.
Team Effort and Legacy
The programme involved pit crews, safety staff, and remote monitoring from Mercedes-AMG’s headquarters in Affalterbach. Partners such as Michelin and Alpitronic provided tyres and charging support.
Mercedes-AMG executives highlighted that the records continue a tradition of long-distance trials at Nardò, previously carried out with experimental vehicles such as the C111 in the 1970s and 1980s.
