Three axial flux motors and 850 kW fast charging? Meet the GT XX.

Mercedes-Benz provided flights from Detroit to Stuttgart and accommodation so Ars could be briefed on the GT XX, as well as some other things we can't publish just yet. Ars does not accept paid editorial content.

AFFALTERBACH, Germany—A few years ago, we were treated to the Mercedes-Benz EQXX. It was, at the time, the pinnacle of Mercedes engineering built for the purpose of maximum electric range. While an impressive piece of machinery that looked like it drove out of Le Mans, it wasn't designed to be a high-performance electric vehicle with an AMG badge. That's ok, though, because there is a high-performance AMG electric concept, called the GT XX, that introduces the world to the future of high-performance AMG electrics and debuts the AMG.EA architecture.

The 800 V AMG.EA isn't like an 800-volt you've experienced before. Mercedes claims that the car can charge at greater than 850 kW over a wide portion of the charging session. While the company didn't provide any graphs, based on the hardware onboard, there's little reason to doubt that claim.

To feed an EV that much power, the charging station would need to output at 1,000 A, and the company worked with its European partner Alpitronic to develop a prototype charging station. The current prototype uses a CCS connector, which is the standard in Europe.
