Mercedes-AMG adds a full-size GT SUV to its performance family
Mercedes-AMG has unveiled the GT SUV as the first full-size sport-utility vehicle developed entirely by its Affalterbach performance division. The new electric model takes the AMG.EA architecture beyond the GT 4-Door Coupé, giving the brand a second vehicle conceived around high-output motors, an 800-volt electrical system and an approach to driving character that remains recognisably AMG. The world premiere took place during Mercedes-Benz's 140th-anniversary celebration in Stuttgart on 17 October 2026, an event that put the manufacturer's historic S-Class programme alongside its new generation of electric performance products.
The important distinction is that this is not a conventional Mercedes-Benz SUV simply fitted with an AMG appearance package. Mercedes-AMG describes an independently developed vehicle with its own lower roof profile, suspension programme and performance objectives. That breadth of engineering is relevant to buyers looking for a grand-touring car with additional luggage and passenger flexibility, but it does not automatically mean that every AMG GT SUV will have the same equipment, maximum performance or battery capacity.
Three model grades form the announced range: GT 53 SUV, GT 55 SUV and GT 63 SUV. Mercedes-AMG says the 53 became available to order on 20 October, with a stated starting price of €113,050 in Germany including local VAT, while the 55 and 63 are scheduled to follow in spring 2027. International prices, local specification and delivery arrangements should be confirmed with the supplying market rather than inferred from that German figure. The order book for the entry-level model is therefore a present development, while some of the most dramatic capabilities belong to versions still due to arrive.
Three power outputs, two distinctly different electric drivetrains
The GT 53 SUV uses a pair of synchronous motors, one at each axle, producing a combined 400 kW or 544 hp in the manufacturer's figures. The front motor can disconnect under lighter loads, while the rear installation uses a two-speed transmission intended to balance immediate response with efficient high-speed running. Its performance specification is formidable in its own right, though the 53 should not be confused with the tri-motor hardware reserved for its larger siblings. This distinction matters particularly when comparing charging choices, driving modes and future servicing.
The GT 55 and GT 63 SUVs adopt three axial-flux motors and the company's high-performance electric drive units. Mercedes-AMG quotes up to 600 kW, or 816 hp, for the GT 55 and up to 860 kW, or 1,169 hp, for the GT 63. These are peak figures rather than a promise of constant output in every operating condition. The manufacturer also identifies liquid cooling, power electronics and a central thermal-management system as essential to repeating demanding acceleration and sustaining performance over time.
For the GT 63, AMG states a 0–100 km/h figure of 2.5 seconds using its one-foot-rollout measurement convention, with an optional Driver's Package enabling a top speed of 270 km/h. Those numbers are appropriate to that specific configuration, not a blanket description of the whole line-up. The more useful question for an owner may be how the vehicle feels over a long drive, where the transitions between regeneration, braking, steering and power delivery can have greater everyday significance than a single acceleration figure.
Charging and thermal control are part of the engineering story
Mercedes-AMG offers a 106 kWh battery for the range and a larger 128 kWh battery for the GT 55 and GT 63 configurations. It gives maximum direct-current charging powers of up to 600 kW for the smaller pack and 710 kW for the larger one, alongside a claimed 10–80 per cent charge in as little as 11 or 12 minutes respectively under the specified conditions. These are laboratory or ideal-infrastructure capabilities, not assurances that a driver will see the quoted power at a typical public charger.
The company's headline claim that up to 450 kilometres of WLTP range can be added in ten minutes relates to the larger battery and its highest-power charging scenario. Mercedes-AMG also describes a very fast ten-minute addition for the smaller battery, but real-world results will depend on charger availability, charge state, ambient temperature and the car's battery-conditioning strategy. Readers planning international motoring should check the infrastructure on their intended routes before treating a maximum charging figure as a trip-planning assumption.
The 800-volt platform is designed to negotiate charging networks that do not all work to the same electrical standard. Mercedes-AMG says the system can switch for 400-volt charging and is intended to accommodate a variety of international fast-charging interfaces. That adaptability could make the GT SUV more versatile across a multi-residence lifestyle, although connector types, station access, tariffs and regional support still require local verification. A car's charging capability and the charging network's ability to deliver it remain two separate things.
Suspension, aerodynamics and cockpit shape the grand-tourer brief
The chassis story goes beyond motor output. AMG ACTIVE RIDE CONTROL+ introduces active pitch and roll stabilisation, standard on the GT 63 and available as an option on the GT 55, according to the manufacturer. The design goal is to limit unwanted body movement while retaining compliant cruising behaviour, a difficult compromise for a substantial high-performance SUV. It will take independent road testing to establish precisely how successfully the finished vehicle delivers that balance over different surfaces and on long journeys.
Mercedes-AMG also highlights variable all-wheel-drive torque distribution, active rear-axle steering and the ability to tailor response and handling through the AMG RACE ENGINEER controls on the higher-output variants. Three physical rotary controls are intended to make some dynamic adjustments more immediate than searching through a touchscreen menu. Owners should nevertheless examine the exact standard and optional specification of the model they order, because a technology described in the range-wide launch material may not appear identically on every derivative.
The exterior uses a comparatively low silhouette, prominent wheel arches and an extended roofline, with active aerodynamic elements designed to respond as speed and vehicle demands change. Inside, the instrument and multimedia displays are arranged around a low, driver-focused seating position, with a separate passenger display available. AMGFORCE Sport+ adds reproduced combustion-engine sounds and simulated shift sensations, an intentionally theatrical solution that may appeal to some drivers and be switched down by others. In a luxury vehicle, the availability of quieter modes can be as relevant as the dramatic demonstration.
What the GT SUV means for high-end motoring and ownership
The announcement offers a clear alternative for an owner who wants sports-car character without giving up a full-size SUV's more flexible layout. Mercedes-AMG's technical information identifies significant luggage capacity and a front storage compartment on selected configurations, but those figures should be read with the specified seating and battery arrangements in mind. A dealer demonstration remains essential for assessing rear-seat comfort, access, visibility and luggage fit, especially for buyers who routinely travel with family or equipment.
Those who divide their time between city residences, airports, marinas and country properties will have different priorities from customers shopping primarily on acceleration. Ease of everyday charging, interior refinement, parking manoeuvrability, reliable travel range and straightforward controls may determine whether the GT SUV works as a genuine all-purpose luxury vehicle. Its five-metre-plus length also makes practical parking and garage dimensions worth checking before orders are finalised; such decisions cannot be made confidently from promotional photographs alone.
The official unveiling was reinforced by a separate Mercedes-Benz account of its 140th-anniversary festival, which identifies the GT SUV as a central world premiere and confirms its position as AMG's first wholly in-house-developed full-size SUV. The performance and charging claims, by contrast, are manufacturer specifications that still await broader independent road evaluation. For now, the established story is a substantial new three-model electric GT SUV family, with immediate German ordering for the 53 and higher-output variants planned for the following spring.
