Mercedes-AMG has gone full send on its first purpose-built electric car, and the numbers demand attention. The new GT 4-Door Coupe arrives in GT63 and GT55 flavours, with the flagship GT63 producing 860kW and 2000Nm from a trio of axial-flux motors. Zero to 100km/h takes 2.1 seconds with rollout. Zero to 200km/h takes 6.4 seconds. Top speed hits 300km/h with the optional Driver's Package.

This is AMG playing offense, not catch-up.

Three Motors, One Mission

The GT runs on Mercedes-AMG's new AMG.EA 800-volt architecture. Two axial-flux motors sit on the rear axle with a third up front, and the technology was developed over more than a decade alongside YASA. The motors are built in Berlin using over 35 claimed world-first manufacturing techniques, which is either impressive engineering or impressive marketing, and probably both.

Pull the steering wheel paddles and you unlock a temporary boost of 110kW in the GT63. Seven drive modes are available, and a Predictive Performance Manager includes both Endurance and Hotlap modes that automatically manage power distribution for track work.

Charging That Actually Keeps Up

Both the GT63 and GT55 share a 106kWh battery with a new lithium-ion chemistry and individual cell cooling. The 800-volt system supports 600kW DC fast charging, getting from 10 to 80 percent in around 11 minutes and adding more than 460km of range in that time. WLTP range sits at up to 696km for the GT63 and 700km for the GT55.

For a 2460kg performance car, those are figures that genuinely change the calculus on long-distance driving.

Familiar Shape, Lower Stance

The body follows the GT XX concept closely. At 5094mm long and just 1411mm tall, the GT63 is 46mm longer and 42mm lower than the outgoing model. A claimed drag coefficient of 0.22 comes from active aero panels, a rear spoiler that deploys above 80km/h, and Venturi underbody channels that add downforce over 120km/h.

Six circular tail-lights, twin power domes on the bonnet, and an illuminated front grille round out the exterior.

What About the Sound?

AMG knows its buyer. A simulated V8 soundscape with artificial gearshift sounds comes standard, aimed squarely at the petrol faithful upgrading from the old twin-turbo PHEV. Whether that satisfies them is a different question entirely.

Production starts mid-2026. The outgoing GT63 S E Performance left showrooms priced from $409,600 before on-road costs. Expect the new car to land considerably higher.
