GT XX: 850kW Fast Charging & 3 Axial Flux Motors Inside
▼ Summary
– Mercedes-Benz invited Ars to Germany to brief them on the GT XX, a high-performance AMG electric concept showcasing the new AMG.EA architecture.
– The GT XX features an 800 V AMG.EA system capable of charging at over 850 kW, requiring a 1,000 A charging station developed with Alpitronic.
– Using the prototype charger, the GT XX can add 400 km (249 miles) of WLTP range in about five minutes under optimal conditions.
– The GT XX’s battery pack uses NCMA cathode and silicon anode materials, with cylindrical cells designed for faster heat dissipation and direct-cell cooling.
– A non-conductive oil cooling system ensures rapid heat expulsion, enabling consistent track performance and fast charging without performance loss.
Mercedes-Benz has unveiled the groundbreaking GT XX, a high-performance electric concept that pushes the boundaries of EV technology with unprecedented charging speeds and innovative engineering. The vehicle represents the future of AMG’s electric lineup, built on the advanced AMG.EA platform designed specifically for electrified performance.
Unlike conventional 800V systems, the GT XX’s architecture supports ultra-fast charging at over 850 kW, a feat made possible through collaboration with European charging infrastructure partner Alpitronic. To achieve this, the prototype charging station delivers a staggering 1,000 amps through a CCS connector, currently the standard in Europe. In ideal conditions, this setup could replenish 400 kilometers (249 miles) of WLTP-rated range in just five minutes, though such high-power chargers are not yet publicly available.
Powering this capability is a cutting-edge battery pack featuring nickel-cobalt-manganese-aluminum (NCMA) cathodes and silicon-enhanced anodes. The cylindrical cells are uniquely designed, taller and narrower than traditional formats, to optimize thermal management. A direct-cell cooling system circulates non-conductive oil between the cells, rapidly dissipating heat to maintain performance during intense driving or repeated fast-charging sessions.
While the EQXX concept prioritized efficiency with its sleek, Le Mans-inspired design, the GT XX shifts focus to raw performance, leveraging three axial flux motors for exceptional power delivery. This setup hints at AMG’s commitment to blending electrification with the brand’s signature driving dynamics. Though still in the prototype phase, the GT XX offers a compelling glimpse into how high-performance EVs could evolve, combining blistering acceleration, track-ready endurance, and charging speeds that rival refueling stops for combustion engines.
The GT XX’s innovations underscore Mercedes-AMG’s ambition to lead the electric performance segment, proving that sustainability and adrenaline can coexist without compromise. As development continues, enthusiasts can expect further refinements before this technology reaches production vehicles.
