Mercedes-AMG's new electric GT 4-Door Coupe will let drivers retune how the car turns into corners, responds to the accelerator and manages wheelspin, using three rotary dials on the centre console. The AMG Race Engineer system is offered on the GT55 and GT63, the two electric variants of the four-door.
The setup pairs a central vehicle-control computer with dials labelled Response Control, Agility Control and Traction Control. Mercedes-AMG product manager Oliver Ganzmann, speaking at the car's launch in Spain, described the agility function as changing the sensation of the car's wheelbase.
How the three dials work
Turning up agility makes the car feel as though it has a shorter wheelbase and turns in more eagerly, Ganzmann said, while dialling it back gives a more stable feel closer to a longer-wheelbase car. The effect comes from adjusting torque distribution to change how the car rotates through a corner, with AMG saying drivers can pick behaviour from slight understeer through neutral handling to controlled oversteer.
Response Control changes how the motors react to accelerator inputs, and Traction Control offers nine levels of intervention. The individual agility and traction settings are available in Sport, Sport+ and Race modes with electronic stability control switched off, while accelerator-response adjustment stays available with stability control on.

The hardware underneath
The GT63 has up to 860kW of power and 2000Nm of torque for the system to manage, while the GT55 is quoted at 600kW. Both use three electric motors, one at the front and two at the rear; the rear pair share a housing but run independently so torque can be split between the rear wheels.
René Szczepek, who oversees driving dynamics simulation and integration at Mercedes-AMG, said a stiff, stable base chassis is a prerequisite for adding that much torque vectoring and software control. The AMG Active Ride Control suspension uses hydraulically linked dampers instead of conventional anti-roll bars, and three-chamber air springs allow the spring rate to change while the hydraulic system controls body roll.

What buyers still don't know
Mercedes-AMG has not announced pricing for the electric GT 4-Door Coupe in the material available, so what the GT55 and GT63 will cost remains unconfirmed. Range figures, battery capacity and charging details for the electric four-door have also not been stated.
Australian availability and local pricing have not been announced either, so buyers here will need to wait for a Mercedes-AMG statement before treating the car as confirmed for this market.
What is clear is the intent behind the dials. Plenty of fast electric cars already let drivers pick a traction level; letting them reshape cornering balance on the move is a rarer offer, and it puts the sort of adjustment usually reserved for a race engineer's laptop into the hands of the person in the driver's seat.
