Mercedes-AMG GT 4-Door Goes Electric — 1,300HP and No V8

The AMG GT 4-Door Coupe has been one of Mercedes-AMG's defining products since its launch in 2018 — a four-door performance car built around a hand-assembled twin-turbocharged V8 engine, positioned to compete directly with the Porsche Panamera and the BMW M5. In that role it has been outstanding: fast, luxurious, sonically spectacular and unmistakably AMG in every way. The V8 was not just a powerplant. It was the entire point.

Today that car has been replaced — and its replacement has no engine at all. The new AMG GT 4-Door is built on a completely new, purpose-built electric architecture called AMG.EA — AMG Electric Architecture. It uses motors developed by YASA, the axial-flux motor specialist that Mercedes-AMG acquired in 2021 specifically to develop next-generation performance EV technology. The result is a car that produces more power than any previous AMG GT 4-Door, charges faster than anything AMG has ever built and arrives at a performance tier that the V8 models could not reach. For die-hard AMG fans who bought this car for its sound and its soul — this is going to be a difficult pill to swallow. The numbers, however, are extraordinary.

AMG.EA is not a modified version of any existing Mercedes EV platform. It is a ground-up, performance-first electrical architecture developed exclusively for AMG — the first time in the brand's history that it has had a bespoke EV platform rather than adapting an existing Mercedes base. The architecture operates on 800 volts, enabling the 850kW charging speeds that no previous AMG product has approached. It is designed from the outset to manage the thermal demands of repeated high-performance use — track driving, repeated full-throttle acceleration and sustained high-speed running — without the power degradation that plagues less sophisticated EV performance cars.

At the heart of AMG.EA are the YASA axial-flux motors. Axial-flux motors — in which the rotor and stator are arranged face-to-face rather than concentrically — offer significantly higher power density than conventional radial-flux motors. This means more power from a smaller, lighter unit — directly benefiting the car's power-to-weight ratio and preserving the agility that defines the AMG driving experience. Combined with an F1-inspired directly-cooled battery pack — in which the coolant runs in direct contact with the cells rather than through a separate heat exchanger — the system can sustain its peak power output under conditions where conventional EV battery systems would be thermally limited.

The top configuration of the new AMG GT 4-Door produces over 1,300 horsepower — making it by far the most powerful AMG production car ever built and one of the most powerful four-door road cars in history. The 0-100km/h time is confirmed at under 2.5 seconds. For context: the previous AMG GT 4-Door in top GT 63 S spec produced 630 horsepower and hit 100km/h in 3.1 seconds. The new car's top specification produces more than twice the power and is approximately 0.6 seconds faster.

Not every variant will produce 1,300 horsepower. The GT53 — the entry configuration — uses a dual-motor setup with a lower power output, targeting a price in the low six-figure range. Higher specifications with tri-motor configurations will follow, working up through the range to the top-output variant. Full details of the power split across variants, along with confirmed pricing for each, will be announced closer to the car's late 2026 on-sale date.

The new AMG GT 4-Door supports DC fast charging at up to 850kW — a figure that currently exceeds the capability of any public charging network. For comparison, the most powerful publicly available chargers operate at 350kW. The 850kW figure represents AMG's declaration of intent for where charging infrastructure is heading — and ensures that when ultra-rapid charging does become widely available, this car will be ready for it. At current 350kW chargers, real-world charging speeds will still significantly surpass anything available on the current AMG GT 4-Door, which does not support DC fast charging at all in its combustion form.

The F1-inspired battery management system plays a critical role here. By cooling the cells directly with coolant rather than via a thermal management layer, the battery can accept charge at a higher sustained rate without cell damage — enabling the 850kW peak figure and maintaining high charging speeds throughout a session rather than only at the very start.

Inside the new GT 4-Door, Mercedes has introduced several details that have no precedent in the brand's history. The most striking is the Sky Control panoramic glass roof — a full-length glass panel with embedded LEDs that can display the AMG logo in light on the interior surface. At night, the effect is extraordinary. During the day, the glass can switch between fully transparent and frosted at the touch of a button — a feature previously seen only on concept cars and now confirmed for production.

The cabin itself uses leather, carbon fibre and metal throughout — and journalists who sat in a pre-production model in Germany described the material quality as seriously high. The layout is screen-heavy — in common with all new Mercedes products — but retains physical controls for key functions. Rear seat passengers receive USB-C ports and their own climate controls. The rear seats themselves are described as more spacious than most four-door coupes — though not quite as generous as a full saloon. The only interior detail that drew criticism in early media previews was the continued use of the same plastic air vent design found in the current S-Class — a minor inconsistency in an otherwise premium cabin.

It would be dishonest to write this article without acknowledging what is being lost. The AMG V8 — specifically the hand-assembled 4.0-litre twin-turbocharged unit that powered the GT 4-Door — is one of the great modern performance engines. Its sound at full throttle, the way it builds power through the rev range, the physical sensation of 630 horsepower arriving through a traditional mechanical connection — these are things that no electric motor can replicate directly. AMG fans who bought the GT 4-Door for its engine character will find something fundamentally different in its replacement.

What they are gaining is equally significant. Over 1,300 horsepower. A 0-100km/h time that makes the old GT 63 S feel slow. 850kW charging. A panoramic roof that displays their brand's logo in light. F1-derived battery technology. And the certainty that AMG — a brand that has built its identity entirely on performance — considers this platform capable of delivering that performance in a new form. Whether the sum of those gains outweighs the loss of the V8 is a question that only driving the car will answer. Late 2026 cannot come soon enough.

Mercedes-AMG has not yet confirmed official pricing for the new GT 4-Door. The GT53 entry variant is expected to start in the low six-figure range — a significant premium over the outgoing model's $113,150 base price, reflecting the cost of the new AMG.EA platform and YASA motor technology. Higher-output variants will command significantly more. Full pricing will be confirmed closer to the late 2026 on-sale date.
