Key Takeaways
The Mercedes AMG GT XX concept car set a new record by traveling 38% farther than the previous record holder, completing a journey of 40,075 kilometers in 7 days, 13 hours, 24 minutes, and 7 seconds.
The car is powered by three axial-flux motors, delivering a total of 1,000 kW, and features an advanced 800-volt immersion-cooled battery with over 3,000 cylindrical NCMA cells.
The battery boasts an energy density exceeding 300 Wh/kg and is housed in a laser-welded aluminum casing with a non-conductive coolant for optimal performance in extreme conditions.
The testing was conducted under challenging conditions in Nardò, with temperatures above 35 degrees Celsius and sustained speeds of 300 km/h, utilizing prototype charging technology with rates of 850 kW.
The AMG GT XX Concept serves as a prototype for the future AMG GT 4-door model, expected to launch in 2026, potentially featuring rapid charging capabilities as a key feature.
Mercedes' AMG GT XX concept car, built on the AMG.EA platform, has recently set a new record by traveling 38% farther than the previous mark held by the Xpeng P7. This record attempt was part of an even more daring challenge to circle the Earth, which measures 40,075 kilometers, within eight days. Remarkably, the team completed this journey in just 7 days, 13 hours, 24 minutes, and 7 seconds. Two vehicles took off at the same time and finished nearly together.
Impressive Specifications
The GT XX Concept features three axial-flux motors that produce a combined power of 1,000 kW. Its core component is an 800-volt immersion-cooled battery made up of over 3,000 cylindrical NCMA cells, yielding an energy density exceeding 300 Wh/kg. This battery is housed in a laser-welded aluminum casing and uses a non-conductive coolant, which helps maintain strong performance even in extreme conditions.
Challenging Conditions
The testing environment in Nardò was tough, with temperatures soaring above 35 degrees in the shade and prolonged, consistent demands at a speed of 300 km/h. Charging utilized specially designed prototype technology from Alpitronic, allowing for charging rates of 850 kW, which is more than double the current high-power chargers that offer 350 to 400 kW. Mercedes claims that this blend of high speed and charging capability optimizes performance for long-distance travel.
The AMG GT XX Concept is seen as a prototype for the future AMG GT 4-door model that will come with electric drive, anticipated to launch in 2026. Should this technology be mass-produced, its rapid charging capability could be a key feature. The record-setting journeys prove that the immersion cooling system functions effectively under prolonged strain and in severe conditions.
