Overview

• The GT XX concept covered 40,075 km in 7 days, 13 hours, 24 minutes at Italy’s Nardò high-speed ring after establishing the 24-hour EV distance mark at 5,479 km.
• Two identical prototypes ran nearly eight days continuously and finished within roughly 25 km of each other, completing about 3,177 laps of the 12.68 km circuit.
• A 17‑driver roster, including F1 driver George Russell, rotated in two‑hour stints while maintaining roughly 300 km/h between ultra‑rapid charging stops.
• Charging averaged around 850 kW (reported up to 900 kW) using purpose-built hardware that far exceeds today’s typical 250–350 kW public fast-charging capability.
• The concept uses three Yasa axial‑flux motors (~1,360 hp) and an >800 V, oil‑cooled NCMA battery designed for extreme thermal stability, previewing the AMG.EA platform for future AMG EVs.
