Mercedes-Benz has achieved a milestone that combines engineering and emotion in equal parts. The German brand has already started manufacturing its new Mercedes-AMG GT 4-Door Coupe a revolutionary electric propulsion system: axial flow so compact that they measure only 8 centimeters wide and, most surprising of all, is that the brand associates it with a system capable of replicating the roar and sensations of a traditional V8 engine.

The technology that redefines size and performance

Instead of conventional radial flow electric motors, Mercedes has opted for axial flow technologyinherited from YASAa British company that it fully acquired in 2021. In these thrusters, the electromagnetic flux travels parallel to the axis of rotation, allowing for a flat, disc-shaped design, with two rotors surrounding a central stator like a sandwich.

This configuration, known as H-configuration, not only drastically reduces the space required, but also delivers greater continuous power and torque. The result is a powertrain that can be pushed to the limit repeatedly without losing performance.

In the AMG GT 4-Door Coupé, the two rear engines measure approximately 8cm each one wide, while the front one is around the 9cm. Together, the three deliver scandalous figures: up to 860 kW (1,169 hp) in the GT 63 4MATIC+ version and 600 kW (816 hp) in the GT 55. The electrical architecture is prepared to overcome the 1,000 kW in future versions.

Hypercar features in a compact format

Thanks to this ultra-compact design, the car accelerates 0 to 100 km/h in just 2.1 seconds. Each axle has its own high-performance propulsion unit (HP.EDU). At the rear, two axial motors are integrated with a single-stage planetary gearbox, all oil-cooled and with silicon carbide (SiC) inverters that withstand high stresses and temperatures.

The rear motors rotate above the 13,000 rpmand the forward surpasses the 15,000 rpm. The latter acts as a booster motor: it is only activated when more power or traction is needed. A disconnection system (DCU) separates it in milliseconds during quiet driving to improve efficiency and reduces drag losses.

The battery inspired by Formula 1

Behind these features is the new AMG High Performance Electric Battery (HP.EB)developed with the experience of the Mercedes-AMG ONE and the Affalterbach team together with the Brixworth specialists. Its new generation cells, the direct cell-by-cell cooling system and its high voltage allow high performance to be maintained in a sustained manner, with great recharge capacity and power density.

This package aims, in the future, at WLTP autonomy greater than the 700 km.

The V8 soul that purists fall in love with

But where Mercedes surprises the most is in the emotional experience. In the mode AMG FORCE S+the GT 4-Door Coupé generates a sound and feel incredibly faithful to a high-performance V8 engine. It includes simulated traction interruptions during gear changes, vibrations and an adapted instrument panel that reinforces immersion.

Whoever gets behind the wheel feels and hears exactly what they would expect from an AMG with a combustion engine.
