Mercedes-AMG’s 1,341-HP Tri-Motor EV Declares War On The Taycan

Meet the Concept AMG GT XX, a lightly disguised performance EV that simulates gears and a V8 engine.

The close-to-production concept previewing AMG's Porsche Taycan rival has been revealed.
It has a brand new AMG-specific EV platform, three motors and a retro-futuristic design.
AMG is pairing its bonkers performance with a simulated V8 and gear shifts.

Mercedes-AMG wants to upend the performance electric sedan segment with a new fastback that packs up to 1,341 horsepower and can hit 223 mph (358 km/h). It will be the first vehicle built on the AMG Electric Architecture (AMG.EA) previewed by the Concept AMG GT XX study, which looks almost production-ready.

The GT XX concept is the clearest vision yet of how AMG plans to go electric: fast, loud and sideways in a plume of tire smoke. It’s not groundbreaking by Chinese or Lucid standards, but it’s still an impressive technical achievement that promises to be more than the sum of its parts and deliver a truly exhilarating drive, which is what everybody expects from an AMG, regardless of what powers it.

Motivating the GT XX is a trio of electric motors: one powers the front axle, and it features two drive units in the back, one for each wheel, allowing for precise torque vectoring, akin to a limited-slip differential cranked up to eleven. Mercedes claims the axial flux motors used in this EV have around three times the power density compared to a radial electric motor.

The AMG.EA architecture runs at 800 volts, allowing for bonkers charging speeds, almost matching the best that China has to offer. We don’t know if this is representative of the production model—it probably is—but the concept can juice up at an average of 850 kilowatts with a power flow of 1,000 amps, with a peak approaching 1 MW, which is enough to add 248 miles (400 km) of WLTP range in around 5 minutes. This is BYD-level insane.

Mercedes states that the very high charging power is possible thanks to an NCMA (nickel, cobalt, manganese, aluminum) battery pack comprised of over 3,000 cylindrical cells with an energy density of 740 Wh/l, which for the whole pack is 300 Wh/l. This battery pack is specific to the concept. This is an engineering flex, and it’s unclear if the production car will have it.

It will likely get the intelligent cell cooling technology that’s in the concept. Each cell is individually cooled using a special non-conductive oil, and it also allows the battery pack to be brought up to temperature quickly through preconditioning to prepare it for DC fast charging.

The manufacturer doesn’t quote a 0 to 60 mph time for the concept, but let’s not kid ourselves: this is a two-second car. It is able to achieve such a high top speed not only courtesy of the power but also thanks to its body that’s slipperier than a bar of soap with a drag coefficient of just 0.198.

The impressive aero comes thanks to the low-slung shape of the vehicle, but also through an active front grille with louvers that open and close depending on cooling needs. Mercedes says they don’t just have an open or closed position and they open in “multiple stages.”

The exterior design will likely remain essentially unchanged for production. It looks retro-futuristic with its oversized grille, shark nose design and three-circle rear lights. The shape of the headlights is similar to what you might see on an AMG GT coupe model, and it looks very sporty overall.
