Mercedes-AMG is putting the finishing touches on its next-generation GT 4-Door Coupé, and it’s doing it the hard way, deep in the frozen north of Sweden.
Ahead of its official reveal in the coming weeks, near-production prototypes have completed final winter testing on snow-covered roads and frozen lakes. The goal is fine-tune traction, stability and control at the very edge of grip.
Software takes centre stage

At the heart of the new model is a system AMG calls Race Engineer: a tightly integrated mix of hardware and software designed to give drivers deep control over how the car behaves.
Three rotary controls allow adjustments to throttle response, cornering behaviour and traction intervention. The “Response Control” function alters how the electric motors react to throttle inputs, ranging from smooth and progressive to sharp and aggressive.
Meanwhile, “Agility Control” changes how the car rotates through corners, effectively shifting its balance from understeer to oversteer. A nine-stage traction control system adds another layer, letting experienced drivers dial in exactly how much slip they want, particularly when stability control is switched off.
Three motors, serious control

This new GT 4-Door isn’t just about software, as it’s backed by a sophisticated electric drivetrain. Three axial-flux motors power the car, enabling highly flexible torque distribution across both axles and even between the rear wheels.
The system can seamlessly shift between rear-wheel drive and all-wheel drive, depending on conditions, while sensors constantly monitor grip and adjust torque in real time. On ice, that means maintaining traction where lesser setups would simply spin away energy.
Supporting it all is AMG’s Performance 4Matic+ all-wheel-drive system, paired with torque vectoring and a high-performance braking setup combining carbon-ceramic hardware at the front with steel brakes at the rear.
Chassis smarts beneath the surface

The suspension also plays a major role. AMG’s Active Ride Control system links the dampers hydraulically, allowing it to vary roll stiffness without traditional anti-roll bars. The result is a wider spread between comfort and outright handling precision.
An 8.2-litre pressure reservoir enables rapid adjustments to ride height and body control, while also contributing to efficiency improvements through optimised aerodynamics and load management.
Battery tech has been tuned for extreme conditions, too. Directly cooled cells ensure consistent performance, with the system able to quickly heat or cool the battery to its optimal operating range, even in sub-zero temperatures.
With more than 500 individual tests carried out in harsh winter environments, AMG’s upcoming electric GT 4-Door is shaping up as a serious performance EV, one designed to deliver not just speed, but precision, regardless of the surface beneath it.
