Mercedes officially released a new pure electric ultra-high-performance sedan - the AMG GT four-door coupe version, marking the brand's entry into the era of ultra-high-performance electric vehicles. The new car draws heavily on the technology of the XX concept car, which previously set a record by driving 24,901 miles continuously at the Nardo high-speed ring test track in southern Italy in less than 8 days. It aims to compete head-on with some "super sports cars" in the electric era.
In terms of power system, Mercedes has rethought the overall architecture of motor and battery technology for this AMG GT, striving to create an electric coupe that can compete with top-end high-performance models. The production model is equipped with three axial flux motors developed by Mercedes subsidiary YASA, with a maximum output of 1,153 horsepower and a peak torque of 1,475 pound-feet. According to the manufacturer, this is the first time in the industry that this type of motor has been used on a large scale in a mass-produced vehicle. Its flat "thin disk" structure makes the entire system weigh only a fraction of the traditional radial motor, but it can output extremely high power, giving the vehicle the ability to accelerate from 0 to 60 mph in about 2 seconds.
The battery system also adopts a new idea, focusing on high performance and high heat resistance. The car is equipped with a tall and extremely thin cylindrical battery cell. The height is much greater than the diameter, and the diameter is only about 1 inch. This design helps the heat inside the battery core to quickly spread from the core of the battery core to the outside. In order to improve cooling efficiency, Mercedes has developed a special high-tech insulating oil that is non-conductive and can avoid the risk of short circuits and allows the cooling oil to flow directly through each cell to achieve "cell-by-cell" liquid cooling management. This cooling system is inspired by F1 racing cars. Officials say it can provide 20 kilowatts of cooling power, which is about four times the cooling capacity of the existing EQS battery. It can also try to avoid thermal attenuation and performance degradation in high-intensity repeated acceleration and track use scenarios.
In terms of electrical architecture, the AMG GT four-door coupe is built on an 800-volt platform, which can support ultra-high-speed charging power of up to 600 kilowatts, significantly shortening the recharge time and further enhancing the vehicle's practicality in long-distance driving and high-frequency track use. However, while pursuing the ultimate performance, the new car also inherits some traditional "performance car experience" designs, such as simulating the sound of an internal combustion engine through a sound effect system. This "onomatopoeic engine sound effect" setting not only emphasizes the sporty atmosphere, but also triggers controversy over "authenticity" among some pure electric fans.
Taken together, with a series of cutting-edge technologies such as axial flux motors, high-performance liquid-cooled batteries and 800-volt high-voltage architecture, the Mercedes-AMG GT four-door pure electric coupe is trying to redefine the standard of "supercars" in the era of electric vehicles and challenge the top performance models of traditional and new forces.
