Overview

• Mercedes says the Concept AMG GT XX covered 5,479 kilometers in 24 hours at the Nardò test oval, surpassing the previous EV mark by about 1,500 kilometers.
• Across 7 days, 13 hours and 24 minutes, the prototypes logged 40,075 kilometers and 25 distance and duration records while lapping mostly at around 300 km/h.
• Two cars ran in parallel with professional drivers rotating roughly every two hours, and both remained operational despite daytime temperatures above 35°C.
• The drivetrain uses three compact axial‑flux motors with about 1,000 kW peak output and an 800‑volt battery of NCMA cylindrical cells with direct oil immersion cooling.
• Mercedes reports using a prototype Alpitronic setup that delivered around 850 kW average charging, enabling about 400 kilometers of energy in five minutes as part of a vehicle‑infrastructure co‑development.
