Mercedes unveiled the Concept AMG GT XX earlier this June as its most ambitious electric performance concept yet. Tested on the legendary Nardò high-speed track in Italy, the prototype has redefined what’s possible for EV endurance, smashing multiple world records in the process.

Record-breaking endurance

The GT XX covered an astonishing 5,479km in just 24 hours, obliterating the previous benchmark by more than 1,500km, smashing the previous record by over 1,500km. But that was only the start. Over 8 relentless days, the car circled the equivalent of the Earth’s circumference— 40,075km in 7 days, 13 hours, 24 minutes, and 07 seconds.

This “Around the world in 8 days” challenge not only showcased extreme speed but also the resilience of AMG’s next-gen drivetrain. At a steady 300 km/h, the GT XX completed over 3,000 laps of Nardò, proving its endurance under brutal conditions. What makes this record endurance run even more impressive is that Mercedes didn’t just bring one AMG GT XX Concept – they used two. Both units set off simultaneously and after a full circumnavigation of the globe each, they crossed the finish line just 25km apart.

It took a team of 17 drivers for this impressive endurance record, including Mercedes F1 driver, George Russell. In the official release, Russell states, “As an F1 driver, I’m used to pushing technology to its absolute limits – the CONCEPT AMG GT XX really impressed me. The axial flux motors respond as immediately and precisely as a Formula 1 drivetrain, but with an endurance that I have only ever experienced with combustion engines.”

Powertrain for the future

At the heart of the GT XX is the upcoming AMG.EA electric platform, featuring 3 axial flux motors and a directly cooled high-performance battery. Together, they produce more than 1000kW, and proved to deliver exceptional consistency during this test.

Axial flux motors are lighter, more compact, and approximately 3 times as power-dense as conventional motors—allowing AMG to achieve Formula 1-like responsiveness. Add to that the liquid-cooled cylindrical NCMA battery cells, inspired by F1 tech, and you get an EV built to extreme endurance.

Commenting on this record-setting achievement, Chairman of the Board at Mercedes-AMG Michael Schiebe added, “An AMG has always been defined by its drivetrain. In the electric world, too, our drive system must be convincing across the board. That’s why we’re the first manufacturer to use axial flux motors and directly cooled batteries in fully electric models. We have now impressively demonstrated how superior these technologies are.”

Ultra-fast charging

One of the standout achievements of the Concept AMG GTX is its charging capability, which was key to this record breaking run at Nardo. With an average charging power of 850 kW, the car could recharge for 400 km of range in just 5 minutes— far beyond what today’s public infrastructure can support. This breakthrough points to what could be possible in the near future for AMG’s production EVs.

A nod to history

Mercedes-AMG has a long legacy of record-setting endurance runs, dating back to the C111 experiments of the 1970s and 80s. The GT XX continues the tradition, this time proving what’s achievable with all-electric power.

Markus Schäfer, Mercedes-Benz CTO, said the project’s mission was simple: “to redefine the very standards of performance with groundbreaking technologies and innovations.”

What it means for drivers

While the Concept AMG FT XX itself won’t go on sale, its technology will shape the upcoming AMG production cars. For Australian performance fans, this signals a future of faster, more powerful, and long lasting EVs that can handle both tacks and long road trips.
