Inside the Record-Shattering Electric Saloon That Drove Around the World in Eight Days

How Did Mercedes-AMG Shatter the Electric Car Endurance Record?

If you’re even a little bit interested in electric cars, the story of the Mercedes-AMG GT XX is one for the ages. Imagine this: a sleek, sunset-orange hyper-saloon lapping a high-speed Italian test track for over a week, racking up more than 25,000 miles—enough to circle the globe at the equator. And it did all this in just under eight days. That’s not just a record; it’s a statement.

But how did Mercedes-AMG pull it off? It wasn’t a publicity stunt or a one-off headline grab. This was a meticulously planned, almost obsessive campaign to push the boundaries of what electric vehicles can do. The GT XX didn’t just break one record—it set 26 new world records, including the most high-profile: 3,404 miles covered in 24 hours. For context, that’s 38% further than the previous record-holder, the Xpeng P7, managed earlier that same month.

What Set the GT XX Apart from Other Electric Cars?

Let’s get into the nuts and bolts. The GT XX is no ordinary EV. It’s built on Mercedes-AMG’s brand-new AMG.EA electric architecture—a platform designed from scratch for high-performance electric cars. Under the hood (well, under the floor and in the axles), you’ll find a triple-motor setup: two axial flux motors at the rear and a smaller booster motor up front. Together, they deliver a staggering 1,341 horsepower.

But raw power wasn’t the only secret sauce. The car’s aerodynamic design is just as impressive, boasting a drag coefficient of 0.19. That’s slipperier than most supercars. And the battery? It’s an oil-immersed, cylindrical-cell pack with direct liquid cooling, capable of charging at up to 900kW. To put that in perspective, you can add 249 miles of range in less than five minutes—faster than most people can grab a coffee.

How Did the Team Overcome Real-World Challenges?

Records like this aren’t set in a vacuum. The Nardò Technical Centre in Italy, where the run took place, threw plenty of curveballs: daytime temperatures soaring past 35°C, nights dropping to 20°C, torrential rain, and even a brief power cut. No simulation could have prepared the team for all that.

Mercedes-AMG’s answer? Redundancy and teamwork. They ran two GT XX cars in tandem, each with its own dedicated crew. The teams—nicknamed Team Blue and Team Green—pushed each other to the limit, but also had to be reined in to avoid overcooking the cars. The operation was massive: 17 drivers (including F1 star George Russell) rotated in eight-hour shifts, backed by over 130 engineers and logistics staff on-site, plus remote support from command centers in Germany. The infrastructure was just as impressive, with over 1.5 miles of charging cable and a pit crew ready to swap tires and wash windscreens at a moment’s notice.

What Was It Like Inside the Record-Breaking GT XX?

You might expect a car that’s just circled the globe in a week to look battered and tired. Not so. Aside from a layer of road grime, the GT XX looked almost untouched. Inside, the cabin was clean and unspoiled, the seat firm, the six-point harness still stiff from days of use. The sense of purpose was palpable.

On the track, the experience was surreal. The car accelerated with supercar intensity, yet in near-total silence. Even at speeds up to 155mph (and an average of 186mph during the record run), there was no drivetrain noise—just the hum of the tires and the wind. The car’s stability and composure were uncanny, thanks to its advanced aerodynamics and active cooling systems. The rear spoiler stayed tucked away for minimal drag, and the wheels’ airflow panels only opened during charging stops to dissipate heat.

How Did Mercedes-AMG Optimize Every Second on Track?

This wasn’t just about brute force or raw speed. Mercedes-AMG brought the kind of data-driven precision you’d expect from a Formula 1 team. Every stint was simulated, analyzed, and tweaked in the months leading up to the attempt. The car’s predictive performance system, intelligent thermal management, and cloud-optimized charging logic all played a role.

Charging stops were a masterclass in efficiency. With the car able to accept up to 965kW—nearly six times the charging rate of the Mercedes-AMG EQE 53—pit stops lasted just two to four minutes. Regenerative braking was so effective it could recuperate up to 600kW of energy, helping stretch every mile.

What Does This Mean for the Future of Electric Cars?

The GT XX’s achievement isn’t just about setting records. It’s about rewriting the rulebook for what’s possible with electric vehicles. Mercedes-AMG didn’t just build a fast EV—they built a predictive, adaptable, and resilient machine that can handle real-world challenges and come out on top.

This record run also hints at what’s coming down the pipeline. The production version of the GT XX’s platform is set to arrive soon, promising to bring much of this technology to the road. Features like ultra-fast charging, advanced thermal management, and predictive performance systems could soon become the new normal for high-end electric cars.

Key Takeaways for Drivers and Enthusiasts

So, what can we learn from the GT XX’s globe-spanning feat? First, the limits of electric vehicle endurance are being pushed further than ever, thanks to a blend of cutting-edge engineering and relentless teamwork. Second, the future of EVs isn’t just about range or speed—it’s about how smartly all the systems work together, from aerodynamics to software. And finally, this kind of innovation isn’t just for the track. The lessons learned here will shape the electric cars we’ll be driving in the years to come.

If you ever doubted that electric cars could be thrilling, resilient, and genuinely groundbreaking, the Mercedes-AMG GT XX just proved otherwise. The outcome? Game-changing. And the story’s just getting started.
