Mercedes-AMG's new electric GT SUV raises the bar for performance SUVs

Mercedes-AMG has taken a major step deeper into the electric performance market with the unveiling of its new GT SUV. Newsroom ZA reports that the model is fully electric and moves the brand into the high-powered full-size SUV segment, a space where size, pace and battery technology all matter at once.

According to Mercedes-Benz, this is the first full-size SUV developed entirely in-house by AMG. It is also the second model to use the AMG.EA electric architecture. That matters because it shows the brand is not simply adapting an existing SUV for electric use. Instead, it has built a dedicated performance platform around battery power and high-output electric motors.

Buyers will be able to choose between three versions: the GT 53, GT 55 and the flagship GT 63. Each one uses a different motor setup, with the range designed to scale from the entry model to the highest-performance version. The line-up gives the SUV broad appeal on paper, from a powerful but less extreme option to a top-end model aimed squarely at headline figures.

The GT 63 sits at the top of the range. Mercedes-AMG says its three axial-flux electric motors produce up to 860kW and 2,000Nm. The company claims the SUV can reach 100km/h from standstill in 2.7 seconds, or 2.5 seconds when measured with a one-foot rollout. With the Driver’s Package, top speed is said to reach 270km/h. Those numbers put the GT 63 in a rarefied bracket even before you look at the rest of the range.

The GT 55 also uses three axial-flux motors. Mercedes-AMG says it develops up to 600kW and 1,860Nm. The GT 53, meanwhile, uses two synchronous motors, one on each axle, with a combined output of 400kW and 800Nm. In simple terms, the three models differ not just in software tuning, but in the number and type of motors they carry, which shapes both performance and how the power is delivered.

Battery and charging claims are a big part of the story. Mercedes-AMG offers 106kWh and 128kWh usable battery options on the more powerful variants. The larger battery is said to deliver up to 700km of WLTP range, while DC charging can reach as much as 710kW depending on the battery version. Mercedes-AMG also says the GT 63 can add up to 454km of WLTP range in 10 minutes under suitable charging conditions. That is the kind of claim that speaks directly to the tension in electric performance cars: strong range on paper, but also the need for very fast charging to keep them practical.

The SUV also comes with fully variable AMG Performance 4MATIC+ all-wheel drive. Newsroom ZA notes that the GT 55 and GT 63 receive the brand’s more advanced three-motor drivetrain, while the GT 53 uses the two-motor setup. The drivetrain choice is not just technical detail. It shapes how the car handles traction, acceleration and power split between the axles, which is especially important in a vehicle that is both heavy and very powerful.

Inside, Mercedes-AMG has fitted a 14-inch multimedia screen and a 10.2-inch digital instrument cluster. An additional 14-inch passenger display is available. The latest MBUX system runs on Mercedes-Benz’s MB.OS platform and integrates ChatGPT, Microsoft Bing and Google Gemini. That means the cabin is being sold not only as a performance space, but as a digital one, with the brand leaning hard into connected tech as part of the premium pitch.

Mercedes-AMG says the GT 53 will be available to order from 20 October, starting at €113,050 in Europe. The GT 55 and GT 63 are scheduled to follow in spring 2027. For now, the headline is clear enough: AMG is using its new electric SUV to show how far it can push power, range and technology in one package.

**Why it matters for South Africans** This is relevant locally because South African car buyers follow Mercedes-Benz and AMG closely, especially in the premium SUV market. Newsroom ZA’s report shows how quickly electric performance models are moving from niche experiments to serious flagship products. The GT SUV also highlights the kind of technology, range and charging capability that premium buyers may increasingly compare against what is available in South Africa, even when a specific model is launched first for Europe. It is a useful snapshot of where high-end motoring is heading.

**What happens next** Mercedes-AMG says the GT 53 opens for orders from 20 October in Europe. The GT 55 and GT 63 are set to follow in spring 2027. Newsroom ZA does not say when, or if, the model will reach South African showrooms.
