A New Benchmark for Performance EVs

The electric performance world has a new record breaker. The Mercedes-AMG GT XX Concept EV, first unveiled in June, has just rewritten the record books by setting 25 new world endurance and distance records during an eight-day test at Italy’s famous Nardò test ring.

The most headline-grabbing achievement? Covering an astonishing 3,405 miles (5,479 km) in just 24 hours, shattering the previous record set earlier this year by the Chinese XPeng P7. With a peak output of 1,341 horsepower and backed by next-generation battery and charging technology, the GT XX demonstrates just how far Mercedes-AMG’s upcoming production EVs can go.

Performance Meets Heritage

While the GT XX looks futuristic, there’s a deliberate nod to history. The striking orange livery and aerodynamic design cues mirror those of the legendary Mercedes-Benz C-111, an experimental 1970s machine that also chased endurance records. Just as the C-111 showcased future engineering breakthroughs, the GT XX serves as a bold statement of AMG’s electrified future, built on the brand’s new AMG.EA EV platform.

Record-Breaking Endurance Run

The test saw two GT XX prototypes run nearly nonstop for eight days straight. Professional endurance drivers, supported by Mercedes-AMG’s motorsport team, took shifts to keep the cars running at blistering speeds. Among the 17 drivers was Mercedes-AMG Petronas F1 driver George Russell, who reported cruising speeds of 186 mph (300 kmph) during his stints.

Charging stops were equally impressive. Thanks to 850 kW ultra-fast charging, pit stops often lasted less than two minutes—enough to top up the battery and get back on track without major delays. Over the course of the run, the GT XX maintained an average speed of 136.6 mph (220 kmph), including stops.

By the end of the test, the cars had racked up 24,901 miles (40,075 km)—equivalent to circumnavigating the Earth’s equator—in just 7 days, 13 hours, 24 minutes, and 7 seconds. Not stopping there, AMG pushed the cars to 25,000 miles (40,234 km), setting a new benchmark time of 7 days, 14 hours, 9 minutes, and 52 seconds.

The Numbers Behind the Records

Here’s a breakdown of the most notable records:

• 12 hours: 1,785 miles (2,873 km)
• 24 hours: 3,405 miles (5,479 km) – new world record
• 48 hours: 6,700+ miles (10,781 km)
• 72 hours: 10,100+ miles (16,249 km)
• 168 hours (7 days): 24,901 miles (40,075 km) – circumference of the Earth

In total, the GT XX claimed 25 different records spanning distances and time durations, solidifying its place in EV endurance history.

Cutting-Edge Technology

What allowed the AMG GT XX to sustain such blistering performance wasn’t just raw horsepower, but a suite of advanced engineering solutions:

• Three Yasa axial flux motors: Two at the rear and one at the front, delivering a combined 1,341 hp. The front motor acts as a booster when needed, keeping the car primarily rear-driven for sharper dynamics.
• Oil-cooled NCMA battery cells: Featuring a new nickel cobalt manganese aluminum chemistry, the battery achieves an energy density of 300 Wh/kg across more than 3,000 cells. Each cell is directly cooled with a non-conductive oil system, ensuring stable thermal management even under extreme stress.
• 850 kW DC fast charging: Far beyond what today’s road-going EVs offer, enabling near-instant recharge cycles during endurance runs.

The Road Ahead

While the GT XX remains officially a concept car, it’s essentially a preview of AMG’s upcoming production four-door electric sedan and crossover models. Many of the technologies demonstrated at Nardò—especially the AMG.EA platform, high-density batteries, and rapid charging system—are expected to filter into road-going models within the next couple of years.

This means AMG is setting its sights firmly on rivals like the Porsche Taycan and Tesla Model S Plaid, but with the added credibility of real-world endurance records to back its performance claims.

Why It Matters

The endurance test wasn’t just about setting records—it was about proving that EVs can sustain ultra-high performance over long distances, overcoming one of the most common criticisms of electric cars. By showing that a fully electric AMG can run at nearly 200 mph (322 kmph) for days on end, Mercedes is positioning itself as a leader in the next era of high-performance mobility.

If the production AMG GT EV comes anywhere close to the GT XX concept’s performance, drivers can expect a car that combines the heritage of AMG’s motorsport pedigree with cutting-edge electrification technology.

Final Thoughts

The Mercedes-AMG GT XX Concept EV didn’t just break records—it obliterated them, covering the equivalent of a trip around the globe in just over a week. With 25 endurance benchmarks smashed, Mercedes-AMG has sent a clear message: the electric era of high-performance driving has truly arrived.

For fans of speed, engineering innovation, and sustainable performance, the GT XX is more than just a concept—it’s a promise of what’s coming next.
