Mercedes-AMG just rewrote the EV endurance playbook. The GT XX concept covered 3,405 miles in 24 hours at Italy’s high-speed Nardò ring, obliterating the fresh benchmark set by XPeng’s P7 and stretching the gap by nearly a thousand miles. The run was independently verified on the 7.8-mile test loop and it was not a one-off fluke. Two GT XX prototypes ran the program and finished within a handful of miles of each other.
AMG did not stop at a single day. The team kept circulating until the odometer ticked past 24,901 miles in under eight days, the equivalent of a lap around Earth. In the process the GT XX stacked up time-based records at 12, 24, 48, 72, 96, 120, 144 and 168 hours, plus a string of distance marks up to 25,000 miles.
The headline numbers are wild, yet the secret sauce is pretty simple. Keep the average speed blistering and cut charging downtime to the bone. AMG says the sweet spot was about 186 mph, which balanced outright pace with stop frequency. When it was time to plug in, the GT XX’s ultra-fast system swallowed power at roughly 850 kW, allowing massive range to be added in minutes and keeping the cars on song.
Seventeen pro drivers from AMG’s GT3 ranks rotated through stints, and the program ran with manufacturer-level precision. The two GT XXs pounded out lap after lap with remarkable consistency, underscoring that the result came from repeatable hardware and process rather than a lucky run.
The concept’s spec sheet helps explain how it pulled this off. A tri-motor layout delivers roughly 1,341 horsepower and a claimed top speed north of 223 mph, while the battery tech borrows heavily from AMG’s F1 and AMG One learnings. The high-performance pack is directly cooled and built to accept charge at rates that exceed anything on today’s public networks, which matters when you are trying to set records instead of headlines.
AMG leadership framed the effort as a proof point for what customers can expect from the brand’s first clean-sheet electric models. CEO Michael Schiebe called out the combination of enormous performance and extremely fast charging, promising the end result will still feel like a true AMG. Judging by the scoreboard at Nardò, that confidence is earned.
What happens next might be the most exciting part. The GT XX previews an upcoming four-door AMG EV riding on the new AMG.EA platform, with production targeted to start next year. If even a slice of this endurance capability makes it to the showroom, the conversation around long-distance electric performance is about to change in a hurry.
