A New Platform Built to Dominate
The AMG GT 4-Door Coupé Electric rides on an entirely new architecture called AMG.EA — a platform developed solely for AMG performance vehicles, not shared with any other Mercedes model. That distinction matters. It means every engineering decision was made with performance as the primary consideration, not cost efficiency or mass-market compatibility.
At the heart of the car sits a 106 kWh battery pack using NCMA chemistry with a silicon-containing anode and an energy density of 298 Wh/kg at the cell level. The 2,660 cylindrical cells are cooled directly with oil — a technology borrowed from motorsport — allowing the pack to sustain performance under repeated hard acceleration without the thermal throttling that plagues many rivals.
The electrical system runs on an 800-volt architecture, enabling the headline charging figure of up to 600 kW. In practical terms, AMG claims a 10-to-80 percent charge in just 11 minutes, with over 460 km of range added in a single 10-minute stop. By comparison, the Porsche Taycan Turbo GT — itself an 800-volt car — peaks at 320 kW and needs 18 minutes for the same 10-to-80 percent charge window.
Three Motors, Not Two — and Why It Matters
Where the Taycan relies on a conventional dual-motor layout paired with a clever two-speed rear transmission, the AMG takes a different route: three axial-flux motors. One sits on the front axle, while two independent motors power each rear wheel separately. The motors themselves come from Yasa, the British axial-flux specialist that Mercedes-AMG acquired in 2021. They are roughly one-third the size and two-thirds the weight of conventional electric motors, yet produce remarkable power density.
In GT 63 trim, the combined output reaches 860 kW (1,169 hp) with 2,000 Nm of torque. The sprint from 0 to 100 km/h takes just 2.1 seconds, with 200 km/h arriving in 6.4 seconds. Top speed, with the optional Driver's Package, is 300 km/h.
The Porsche Taycan Turbo GT with the Weissach Package — the most extreme version available — produces 760 kW (1,034 hp) and 1,240 Nm of torque, covering 0-100 km/h in 2.2 seconds with a 305 km/h top speed. The AMG is faster in acceleration, produces significantly more torque, and charges nearly twice as fast. On paper, it is the stronger machine in every category that matters on a spec sheet.
The real difference, though, may be in how that power is delivered. Two independent rear motors allow torque vectoring with a precision that a single rear motor — even one with a two-speed gearbox — cannot replicate. Each rear wheel receives exactly the torque it needs, millisecond by millisecond, enabling sharper cornering, more stable high-speed behaviour, and a degree of control that transforms how the car moves through corners. AMG says drivers can initiate drifts with as little as 40 percent throttle input.
The Softer Side: Range and Everyday Usability
Performance saloons live or die by their daily usability, and here the AMG makes a strong argument. The WLTP range for the GT 63 spans 596 to 696 km depending on specification — figures well ahead of the Taycan Turbo GT's 342 to 345 miles (approximately 550 to 555 km) in Weissach Package form.
The second variant in the lineup, the GT 55 4-Door Coupé, offers 600 kW (816 hp), 1,800 Nm of torque and 0-100 km/h in 2.5 seconds — still deeply impressive — with WLTP range climbing to a claimed 700 km. For buyers who want performance without compromising on between-charge distances, the GT 55 may prove the more pragmatic choice.
Inside, AMG has fitted a 10.2-inch instrument cluster and a 14-inch central touchscreen running the new MB.OS software platform with AI integration. Boot space is a practical 507 litres. The chassis comes equipped with AMG ACTIVE RIDE CONTROL air suspension and active rear-wheel steering with up to six degrees of articulation — the kind of hardware that makes a car feel agile in town and planted on the motorway.
Stuttgart vs. Sindelfingen
Production of the new AMG GT 4-Door Coupé Electric begins in summer 2026 at the Sindelfingen plant in Germany. Pricing has not been officially confirmed, though Mercedes-AMG has stated it will be "aligned with comparable predecessor models." The outgoing AMG GT 63 S E Performance 4-Door started at around €200,000 in Europe, placing it squarely in Taycan Turbo GT territory, where prices begin at approximately £189,200 in the UK.
The Taycan has had five years to establish itself as the gold standard of performance EVs. It remains a forensically engineered machine with a real-world track record — a car with proven reliability, a widespread Porsche service network, and a driving character that has earned genuine admiration from journalists and owners alike. None of that disappears overnight.
But what Mercedes-AMG has produced is, on almost every measurable dimension, a more potent machine. More power, more torque, faster charging, greater range, and a more sophisticated torque management system. The Taycan defined the genre. The AMG GT Electric intends to redefine it.
What is the WLTP range of the Mercedes-AMG GT 63 Electric?
The AMG GT 63 4-Door Coupé Electric offers a WLTP range of 596 to 696 km depending on the specification chosen. The less powerful GT 55 variant claims up to 700 km of WLTP range.
How does the AMG GT 63 Electric's charging compare to the Porsche Taycan?
The AMG GT 63 Electric supports up to 600 kW of DC charging and achieves a 10-to-80 percent charge in approximately 11 minutes. The Porsche Taycan Turbo GT peaks at 320 kW and needs around 18 minutes for the same charge window — a significant difference on long journeys.
When will the Mercedes-AMG GT 4-Door Coupé Electric go on sale?
Production is scheduled to begin in summer 2026 at Mercedes-Benz's Sindelfingen factory in Germany. Order books were set to open shortly after the car's official reveal in May 2026. Pricing has not been officially confirmed but is expected to be in line with the outgoing AMG GT 63 S E Performance.
