\n AI Quick Summary <\/h3>\n
The Mercedes-AMG Concept GT XX set a new electric vehicle endurance record, covering 5,479 km in 24 hours at the Nard\u00f2 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.<\/p>\n This summary was generated by AI using this article\u2019s content.<\/small>\n\n 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\u2019s circumference, totalling 40,075 kilometres in 7 days, 13 hours, 24 minutes, and 7 seconds.<\/p>\n\n\n\n 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.<\/p>\n\n\n\n In total, the programme required 3,177 laps of the 12.68-kilometre Nard\u00f2 circuit. Drivers rotated in two-hour shifts. Daytime track temperatures reached 35\u00b0C, but the vehicles maintained full function throughout the schedule.<\/p>\n\n\n\n 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).<\/p>\n\n\n\n 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.<\/p>\n\n\n\n Charging tests showed the vehicle could recover energy for about 400 kilometres in five minutes.<\/p>\n\n\n\n The programme involved pit crews, safety staff, and remote monitoring from Mercedes-AMG\u2019s headquarters in Affalterbach. Partners such as Michelin and Alpitronic provided tyres and charging support.<\/p>\n\n\n\n Mercedes-AMG executives highlighted that the records continue a tradition of long-distance trials at Nard\u00f2, previously carried out with experimental vehicles such as the C111 in the 1970s and 1980s.<\/p>\n\n\n\n Find the best Mercedes-Benz cars for sale in the UAE<\/a>.<\/p>\n\n\n\nRead Next<\/h4>\n
