With the disclosing of the CONCEPT AMG GT XX, Mercedes-AMG as soon as once more demonstrates why the Affalterbach-based efficiency model has earned its popularity as a relentless pioneer in automotive engineering. From the corporate’s earliest victories in motorsport to its groundbreaking data on among the world’s most demanding take a look at tracks, AMG has all the time embodied the pursuit of uncompromising efficiency. The most recent idea is not only one other step ahead; it’s a daring leap into the electrical way forward for high-performance automobiles.
With the CONCEPT AMG GT XX, the model is setting new world data and providing a preview of what its AMG.EA electrical structure will deliver when it enters manufacturing within the close to future. This idea is just not merely a design research however a expertise demonstrator that has already confirmed itself below among the most excessive endurance exams ever undertaken by an electrical automotive.
Mercedes USA reported on August 25, 2025, that its CONCEPT AMG GT XX broke a complete of 25 long-distance data on the legendary high-speed take a look at observe in Nardò, Italy.
Pioneering Expertise on the Core
On the coronary heart of the GT XX lies a revolutionary drivetrain consisting of three axial-flux motors and a immediately cooled, high-performance battery. These aren’t theoretical applied sciences—they’re production-ready improvements designed to enter collection manufacturing below AMG.EA. Collectively, they unlock a brand new dimension of energy, torque supply, and long-distance endurance.
These groundbreaking motors had been initially developed by YASA, a completely owned subsidiary of Mercedes-Benz AG, a British electrical motor specialist. Mercedes-AMG, in shut collaboration with YASA, elevated this idea to a wholly new stage of efficiency.
Axial-flux motors differ considerably from the radial motors present in almost each different EV in the present day. Their structure makes them way more compact and light-weight whereas additionally tripling energy density. This enables AMG to ship ranges of steady output and repeatable peak efficiency that conventional EV motors can not maintain. The truth is, the GT XX’s triple-motor setup generates a peak output exceeding 1,000 kW (>1,341 hp)—a determine that cements its place among the many strongest electrical prototypes ever created.
A Method 1-inspired battery system helps the motors, engineered completely from scratch in Affalterbach. Constructed with cylindrical NCMA cells in a tall, slender format, the pack achieves an power density of over 300 Wh/kg. The cells are immediately cooled by an electrically non-conductive oil, making certain that every of the greater than 3,000 cells stays on the best working temperature even below repeated high-load situations. This direct cooling not solely preserves battery well being but additionally permits extraordinary charging speeds: the GT XX recharges at energy ranges of over 850 kW, including as much as 400 km of vary in simply 5 minutes.
This stage of thermal management and charging functionality surpasses what present world charging networks can ship, positioning the AMG.EA system as a future-proof answer, prepared for tomorrow’s infrastructure.
Nardò: The Stage for Historical past
To show these claims, Mercedes-AMG selected probably the most demanding testing venues on the planet: the Nardò Technical Heart in southern Italy. Identified for its 12.68-kilometer high-speed ring, Nardò has served for many years because the proving floor the place the quickest and most superior automobiles are pushed to their absolute limits.
It was right here that the CONCEPT AMG GT XX broke 25 long-distance world data, together with probably the most coveted: the document for the best distance traveled by an electrical car in 24 hours. The earlier benchmark, slightly below 4,000 kilometers (2,485 miles), was obliterated. The GT XX coated 5,479 km (3,404 mi) in a single day—an astonishing 38 % enchancment and greater than 1,500 kilometers additional than the prior document holder.
However AMG wasn’t content material to cease at one document run. The engineers conceived a much more formidable problem: to drive the space of the Earth’s circumference—40,075 km (24,901 mi)—in lower than eight days. Impressed by Jules Verne’s basic Across the World in 80 Days, this system was aptly named “Across the World in Eight Days.”
The problem demanded not solely endurance but additionally an unwavering tempo. For greater than per week, the GT XX maintained a relentless pace of 300 km/h (186 mph), pausing just for ultra-fast recharging. Every time the automotive left the charging station, it rocketed again up to the mark, repeating this brutal cycle 1000’s of instances. Regardless of the punishing schedule, the drivetrain and battery carried out flawlessly.
A International Circumnavigation in Document Time
On the morning of August 25, 2025, the CONCEPT AMG GT XX achieved its audacious purpose: finishing the equal of a circumnavigation of the globe in 7 days, 13 hours, 24 minutes, and seven seconds, comfortably forward of the goal time. Alongside the best way, the automotive not solely secured its 24-hour distance document but additionally gathered quite a few extra long-distance and endurance titles.
Remarkably, AMG deployed not one however two GT XX prototypes in parallel. Each automobiles launched into the mission concurrently and crossed the end line simply 25 kilometers aside—a margin of lower than two laps of Nardò’s high-speed ring after greater than per week of continuous driving. This near-identical efficiency underscored not simply the power of a single automotive, however the repeatability and reliability of your complete drivetrain platform.
By the top of the problem, this system had required 3,177 laps of the circuit, averaging greater than 5,300 km (3,293 mi) per day. Drivers rotated in two-hour stints, sustaining focus and precision via each scorching daytime warmth—as much as 35°C (95°F) within the shade—and cooler nighttime situations. The automobiles endured all of it with out mechanical fault or noticeable decline in efficiency.
The Human and Technical Staff Behind the Feat
Whereas the GT XX itself was the star, the achievement additionally highlighted the coordinated efforts of the AMG crew and its companions.
Pit Crews ensured fast tire adjustments and flawless recharging operations.
Distant Diagnostics linked Affalterbach engineers to Nardò in real-time, offering 24/7 monitoring of battery well being, motor temperatures, and software program programs.
Michelin, as a tire provider, developed specialised compounds to deal with the relentless high-speed hundreds.
Alpitronic, a charging expertise accomplice, equipped {hardware} able to delivering the unprecedented 850 kW charging charges required for this system.
Security crews and medical employees stood on fixed alert to handle the dangers inherent in a steady high-speed marketing campaign.
The end result was a seamless integration of human precision and technological innovation, showcasing AMG’s potential to orchestrate not solely record-breaking machines but additionally record-breaking packages.
A New Dimension of Electrical Efficiency
What units the CONCEPT AMG GT XX aside is not only its peak horsepower or its futuristic battery chemistry, however its potential to ship sustained excessive efficiency over lengthy distances.
The GT XX maintained near-maximum output for days on finish. The axial-flux motors allowed for repeated accelerations to 300 km/h, whereas the immediately cooled battery ensured constant thermal stability and ultra-fast recharge cycles. This mixture makes the AMG.EA platform a game-changer for the way forward for high-performance EVs, the place vary, sturdiness, and recharge pace should coexist with uncooked pace and energy.
Our Take
Electrical automobiles aren’t solely probably the most eco-friendly and cost-effective possibility on the street, however in addition they stand as among the quickest machines ever constructed.
EVinfo.web reported that YASA’s groundbreaking Axial Flux motors will possible someday present up in on a regular basis EVs. “While actually getting used within the area of interest sports activities automotive sector in the present day, over time we’ll see that filter via to Mercedes-AMG automobiles, after which into the automotive sector extra broadly,” mentioned YASA CEO Tim Woolmer.
