MERCEDES-AMG GT XX CONCEPT: THE EV THAT JUST DROVE AROUND THE WORLD IN EIGHT DAYS - BEAT THAT PHILEAS FOGG!
Mercedes-AMG has never been shy about flexing, and with the new CONCEPT AMG GT XX, Affalterbach has just rewritten what’s possible for electric performance. This isn’t some shiny design study that’ll collect dust in a museum - it’s a rolling, howling, battery-fed proof of concept that’s already smashed records at the infamous Nardò test track in Italy. And when we say smashed, we mean obliterated. The GT XX is AMG’s test mule for its upcoming AMG.EA electric performance platform, set to hit production next year. Underneath that futuristic retro-styled body sits a futuristic drivetrain: three axial-flux electric motors and a directly cooled high-performance battery, tech pulled straight out of motorsport and reimagined for the road. Think Formula 1 meets sci-fi. Mercedes-AMG didn’t just want to create headlines; they wanted to rewrite history, so they sent the GT XX to Nardò, the legendary high-speed ring where the fastest cars on Earth prove their worth. Over eight relentless days, two cars ran non-stop, only pausing for pit stops and charging sessions at a mind-bending 850 kW. The results are staggering: 5,479 km in 24 hours - that’s 1,518 km further than the previous EV record, and nearly 38% more distance. 40,075 km total in 7 days, 13 hours, 24 minutes, 07 seconds - the exact circumference of the planet. Jules Verne needed 80 days. AMG needed one week. Also interesting is that they used two cars, and they ended up finishing just 25 km apart after 3,177 laps. For perspective: the GT XX averaged 300 km/h, day and night, in 35-degree Italian heat.
The secret weapon - axial-flux motors. Forget the chunky motors in your average EV. AMG tapped YASA - a British electric motor specialist now under the Mercedes-Benz umbrella - to supply axial-flux motors. These things are smaller, lighter, and three times more power-dense than conventional units.
In the GT XX, three of them are strapped into AMG’s HP.EDU (High-Performance Electric Drive Units). Two oil-cooled motors sit on the rear axle, paired with compact gearboxes and inverters, while the front motor acts as a booster when traction or extra power is needed. The combined output is over 1,000 kW, or more than 1,360 hp. All of it electric. All of it repeatable. The battery is pure AMG wizardry, with 3,000+ NCMA cylindrical cells cooled by an electrically non-conductive oil. This keeps temps in check even when charging and discharging at insane levels. Thanks to its 800V architecture, the GT XX can gulp electrons fast enough to add 400 km of range in just five minutes. That’s the distance from Nardò to Naples in the time it takes to grab an espresso. And while most EVs wilt under repeated high-speed runs, AMG’s battery tech thrives. Day after day at 300 km/h? No sweat. Literally.
This wasn’t a solo act. A pit crew, engineers in Affalterbach, Michelin tyre specialists, and charging wizards from Alpitronic kept the cars going around the clock. Drivers rotated in two-hour shifts, hammering the accelerator, recharging, and diving back onto the oval like it was Le Mans on repeat. The GT XX isn’t merely a record-chasing stunt car. It’s the clearest glimpse yet at the future of AMG’s road cars. If this is what their test mule can do, imagine the production models. We’re talking about EVs with the endurance of a diesel, the pace of a hypercar, and the charging speed that makes pit stops look old-fashioned. Mercedes-AMG wanted to show the world that electric doesn’t mean compromise. With the GT XX, they’ve shown that it means domination.
Take a look at the YouTube video that shows off everything that's awesome about the AMG GT Concept. It's an odd thing with a modern retro styling that looks new, yet old. It is orange though, and that scores massive points with us: The New CONCEPT AMG GT XX | Walkaround | Mercedes-AMG
