Mercedes-AMG GT XX Concept Sets 25 EV Distance Records in Weeklong Nardò Run

The Nardò demonstration highlights AMG.EA technology optimized for sustained high‑speed endurance.

Overview

  • The prototypes covered 5,479 km in 24 hours and 40,075 km in 7 days, 13 hours, 24 minutes and 07 seconds, with the team later pushing to 25,000 miles.
  • Two GT XX cars ran simultaneously and finished roughly 25 km apart after 3,177 laps of the 12.68 km Italian test track.
  • A 17‑driver roster rotated in two‑hour stints at about 300 km/h, stopping only for charging and driver changes.
  • Ultra‑fast DC charging around 850 kW enabled roughly 400 km of range in about five minutes, using infrastructure beyond today’s public networks.
  • The concept uses three axial‑flux motors (about 1,360 hp) and an >800‑volt battery with directly cooled NCMA cylindrical cells to manage heat and sustained loads.
