On August 25th, Lei Jun posted on Weibo, "This is incredible! This result is a bit outrageous. Congratulations to Mercedes-Benz." The CEO, who had just transformed the Xiaomi YU7/SU7 into a "performance beast," clearly saw awe-inspiring technological sophistication in the AMG GT XX concept car. When a company that prides itself on its three-electric technology and extreme performance begins to sincerely praise a competitor, it often means the other party has truly come up with a breakthrough solution.
The Mercedes-AMG GT XX concept car is so striking because it uses systematic engineering thinking to push the boundaries of electric performance. Its axial flux motor is a breakthrough in electrodynamics.
Developed by Mercedes' YASA subsidiary, this electric motor achieves three times the power density at one-third the mass and volume of conventional motors. The three motors' coordinated output of over 1,000 kilowatts not only provides for furious instantaneous acceleration but also maintains astonishing stability under sustained high loads—the most challenging technological barrier to overcome in the electric performance arena.
During extreme testing at Italy's Nardo Circuit, the system demonstrated a remarkable feat: surviving 24 hours at a constant speed of 300 km/h, it ultimately covered 5,479 kilometers. Furthermore, the Mercedes-Benz test vehicle covered 40,075 kilometers in 7 days and 13 hours, an average of 5,300 kilometers per day. This repeatable performance demonstrates Mercedes-AMG's unwavering control over the reliability of its electric drive systems.
Underpinning this performance is an energy management system inspired by Formula 1 racing. Utilizing high-energy-density battery cells (over 300 watt-hours/kg) using the NCMA chemistry, coupled with innovative direct cell cooling technology—a laser-welded aluminum housing with independent cooling channels—keeps each cell at its optimal operating temperature. This enables the vehicle to achieve an average charging power exceeding 850 kilowatts (recharging for 400 kilometers in just five minutes) while maintaining battery stability under extreme operating conditions.
As Michael Schaeffer, Chairman of the Board of Management of Mercedes-AMG, said: "The core of the electric era is still the power unit, but performance standards need to be redefined." When these breakthrough technologies will be mass-produced with the AMG.EA architecture in 2026, Mercedes-AMG is proving that traditional luxury brands can still use their deep engineering accumulation in the electric era to impress even the popular Lei Jun - this may be the true meaning behind Lei Jun's word "perverted".
