Mercedes-AMG GT 4-Door EV final winter testing details

Mercedes-AMG reports final winter tests of its GT 4-Door EV in Sweden, highlighting three-motor setup, AMG RACE ENGINEER and new battery system. Learn more.

Final winter testing in Arjeplog has made one thing clear: the new Mercedes-AMG GT 4-Door Coupé is no longer a distant concept, but a near-production electric performance car built around a three-motor architecture and a completely reworked driving dynamics system.

On frozen lakes and snow-covered tracks in northern Sweden, engineers focused not only on traction and stability. The spotlight was on the new AMG RACE ENGINEER system, which allows precise adjustment of throttle response, cornering behavior and slip control. Three dedicated rotary controls enable a wide range of driving characteristics — from stable to deliberately oversteering setups — with full functionality available primarily when stability control is switched off.

This is where the significance of the model becomes clear. Mercedes-AMG is attempting to translate its traditional driving character into a fully electric format. That effort goes beyond software tuning. For the first time in an AMG electric sports car, a system with three axial flux motors is used, offering higher power density, reduced weight and a more compact layout. These motors were developed with YASA, a Mercedes-Benz subsidiary, and are intended for series production.

The AMG Performance 4MATIC+ all-wheel drive system works with this three-motor setup to distribute torque variably between the axles and individually across the rear wheels. This enables precise torque control and predictable handling on low-grip surfaces. The transition between rear-wheel and all-wheel drive is seamless and managed by integrated control algorithms within the vehicle architecture.

Equally important is the battery system. It uses direct cooling of each individual cell with a non-conductive oil, which not only dissipates heat but also enables targeted heating. This approach is designed to maintain consistent performance and efficiency, even under repeated high loads and in extremely cold conditions.

The AMG ACTIVE RIDE CONTROL suspension further supports this setup with hydraulically interconnected dampers and semi-active roll stabilization. It allows the car to shift between comfort and precision depending on driving conditions, enhancing both stability and responsiveness.

The winter testing program itself includes more than 500 individual tests, from ice tracks to climbs with gradients of up to 20 percent. These conditions allow engineers to explore vehicle limits more quickly and fine-tune control systems with greater accuracy.

The technological foundation of the model is closely linked to the Concept AMG GT XX, which introduced the AMG.EA architecture and demonstrated capabilities such as over 1,000 kW of power and extremely high charging performance. While many of these technologies are transitioning into production, the final specifications of the upcoming GT 4-Door Coupé have not yet been disclosed.

With final winter testing complete, Mercedes-AMG is preparing to present its next-generation electric performance car in the coming weeks, offering a clearer picture of how its signature driving dynamics translate into the electric era.
