Mercedes AMG GT XX covers longest distance for an EV in 24 hours

The recently revealed Mercedes-AMG GT XX concept travelled 5,479km in just 24 hours at the Nardo test track in Italy, setting a world record for an electric car. AMG GT XX, the first EV prototype from Mercedes’ storied performance division, beat the XPeng P7 (3,961km), Xiaomi YU7 Max (3,945km) and even the Mercedes CLA (3,718km). Besides the 5,479km feat, the AMG EV set 2 dozen records on the track.

1. The GT XX covered a distance of 40,075km (Earth’s circumference) in almost 8 days
2. Mercedes-AMG F1 driver George Russell also drove the concept on the Italian track

Mercedes AMG GT XX records on the Nardo track

2 GT XX concepts were used; stops made only for rapid charges 

The 24-hour achievement, independently verified by Mercedes, is part of an extensive 8-day testing campaign at the 12.5km Nardo ring. Other records shattered by the GT XX include endurance marks for 48 hours (10,860km) and 120 hours (26,808km), alongside new distance benchmarks for 2,000km (8.4 hours), 20,000km (88.41 hours) and 40,000km (181.02 hours).

Mercedes-AMG F1 driver George Russell took part in the GT XX testing project.

However, the standout achievement came when the electric vehicle racked up 40,075km – the circumference of Earth – non-stop on the high-speed oval in nearly 8 days (181.24 hours). Mercedes named the challenge ‘Around the world in eight days’ as a nod to Jules Verne’s famous novel Around the World in 80 Days. Two GT XX concepts and a team of 17 professional drivers from AMG’s GT3 motorsport programme – among them Mercedes-AMG F1 driver George Russell – set the titles. Stops were made only for rapid charges at around 850kW.

Mercedes AMG GT XX battery and motors

144kW battery, 1,360hp combined output from 3 motors 

The GT XX concept previews the first series-production electric vehicle from Mercedes-AMG. It uses three compact, lightweight axial flux motors - two at the rear and one at the front - together delivering 1,360hp, all-wheel drive and a top speed north of 360kph. These motors are typically seen in hybrid supercars such as the Lamborghini Temerario and Ferrari SF90 Stradale, making this their first use in a pure EV.

The 114kWh NMC battery, inspired by learnings from the AMG One hypercar and F1 tech, uses slim cylindrical cells with aluminium casings for better cooling and faster energy discharge. Direct cooling not only helps sustain peak power but also enables ultra-fast charging for the 800V battery: as much as 400km of range in 5 minutes at up to 850kW.
