Mercedes-AMG is taking electric performance to an entirely new level with the unveiling of its all-new GT SUV, a high-performance machine delivering up to 1,153 horsepower. Developed from the ground up on AMG’s dedicated AMG.EA electric architecture, this full-size luxury SUV combines breathtaking acceleration, advanced electric motor technology, ultra-fast charging, and everyday practicality. The lineup includes three variants, the GT 53, GT 55, and flagship GT 63, each offering a distinct balance of power and performance.

With features such as axial-flux electric motors, an 800-volt battery system, advanced active suspension, and a technology-rich cabin, Mercedes-AMG aims to prove that going electric does not mean sacrificing driving excitement. Scheduled to reach U.S. dealerships in summer 2027 as a 2028 model, the GT SUV is also preparing to challenge rivals such as the Porsche Cayenne Turbo Electric. From its extraordinary power figures to its family-friendly interior, here’s everything you need to know about Mercedes-AMG’s new electric performance SUV.

1. Mercedes-AMG GT SUV Marks a New Era of Electric Performance

Mercedes-AMG, the performance division of the company, has announced the first all-electric AMG model, a high-performance GT SUV developed exclusively by Mercedes-AMG on the new AMG.EA dedicated architecture. The all-electric SUV promises high power, fast acceleration, cutting-edge electric technology and the practicality of a full-size luxury SUV, as well as AMG driving performance. Deliveries of the model will begin globally in early 2027, with U.S. dealers receiving the 2028 model in the summer of 2027. The all-electric GT SUV will compete with ultra-high-performance EV SUVs that appeal to enthusiast families, AMG said.

AMG’s Electric SUV Launch Highlights:

• Entirely new AMG.EA electric architecture
• First in-house full-size performance SUV
• Three distinct electric variants introduced
• U.S. arrival scheduled for 2027
• Luxury practicality meets extreme performance

The initial lineup includes three models: the dual-motor AMG GT 53 SUV, tri-motor AMG GT 55 SUV, and flagship tri-motor AMG GT 63 SUV. Each offers different power outputs, weight, and driving characteristics. The GT 63 delivers maximum power, the GT 55 provides another powerful tri-motor option, while the lighter GT 53 offers a more accessible entry into AMG’s electric lineup. This range gives buyers multiple performance levels within one dedicated vehicle family. Built on AMG’s own electric architecture, the SUV combines powerful acceleration, advanced chassis engineering, and everyday practicality.

2. The AMG GT 63 SUV Delivers Up to 1,153 Horsepower

The Mercedes-AMG GT 63 SUV is at the top of the range and features 3 axial-flux electric motors, with a combined maximum output of 1,153 hp and 2,000 Nm. Its continuous output is 711 hp, which you get when you keep your foot off the floor and then keep it there for more than five seconds. Mercedes claims the Mercedes-AMG GT 63 can accelerate from 0 to 60 miles per hour in 2.6 seconds (2.4 seconds with a one-foot rollout), accelerate from 0 to 100 km/h in 2.7 seconds, and from 0 to 200 km/h in 6.8 seconds. I’ve also written other articles about Mercedes AMG electric cars.

GT 63 Performance Figures Explained:

• Peak output reaches 1,153 horsepower
• Maximum torque reaches 2,000 Nm
• Continuous output remains at 711
• Zero-to-sixty takes 2.6 seconds
• Optional package enables 168 mph

The GT 63’s top speed is electronically limited to 168 mph (270 km/h) with the optional Driver’s Package. To maintain stability at high speeds, AMG combines its three-motor setup with advanced torque distribution, sophisticated suspension, and aerodynamic features. Despite weighing 5,942 pounds (2,695 kg), the SUV delivers impressive acceleration, supported by a large 128 kWh usable battery that supplies energy to its powerful motors. These features establish the GT 63 as the flagship of the electric SUV lineup, demonstrating how Mercedes-AMG uses its dedicated electric architecture to deliver exceptional power, rapid acceleration, and advanced performance technology without sacrificing luxury and practicality.

3. Axial-Flux Motors Give the GT 55 and GT 63 Their Performance Advantage

The AMG GT 55 and GT 63 are equipped with highly-efficient axial-flux electric motors, which are flat and space-efficient, and offer a high power-to-weight ratio. Mercedes bought the British specialist YASA in 2021 to expand its knowledge of the tech, which also sees use in performance cars like the Ferrari 296 GTB and McLaren Artura. The motors produce impressive amounts of power without having to accommodate larger heavier assemblies, giving each AMG SUV strong performance and torque delivery using a sophisticated all-wheel-drive setup.

Axial-Flux Engineering Advantages:

• Compact motors deliver substantial power
• Flat geometry improves power-to-weight ratio
• Two rear motors enable torque-vectoring
• Front motor supplies additional traction
• Automatic decoupling improves drivetrain efficiency

Both tri-motor models feature two axial-flux motors at the rear axle for propulsion and precise torque vectoring, while a third motor at the front provides additional power and traction when needed. Under lighter loads, the front motor automatically disconnects to improve drivetrain efficiency. This arrangement distributes power across all four wheels, helping control the SUV’s considerable weight during acceleration and cornering without requiring every motor to operate continuously. Although the GT 55 shares the GT 63’s three-motor architecture, it produces lower peak power, allowing Mercedes-AMG to offer different performance levels while distinguishing both models from the dual-motor GT 53.

4. The AMG GT 55 Offers 805 Horsepower in a Tri-Motor Package

Sitting between the GT 53 and ultimate GT 63 is the Mercedes-AMG GT 55 SUV, which offers astonishing levels of performance with the same trio of axial-flux motors found in its more potent sibling. Its electric motor system generates 805 horsepower and 1,860 Nm of torque (with sustained output of 711 horsepower) but, despite having less power than the GT 63, it delivers all the benefits of these motors to boost performance. Its trio of motors – two at the back and one at the front are capable of working together to support complex torque split between all four wheels, increasing traction on the road and helping the SUV deliver all of the power that AMG.EA electric performance promises.

GT 55 Power and Acceleration Details:

• Peak output reaches 805 horsepower
• Maximum torque reaches 1,860 Nm
• Continuous power remains at 711
• Zero-to-sixty takes three seconds
• Three motors provide all-wheel-drive capability

The GT 55 gets to 60 mph in an estimated 3.0 seconds; 2.7 seconds with a one-foot rollout. It shares the GT 63’s 128 kWh usable battery pack with a 22-module pack capable of supporting its three motors. The SUV also has all-wheel drive and stable interior and exterior aerodynamics-along with rear-axle steering-that can help the SUV stay composed and controllable. These features make it clear that while horsepower may be king, traction, smooth acceleration and vehicle control are just as important. With a blend of 805hp, axial-flux motors and a large battery, the GT 55 delivers a happy medium between the all-in GT 63 and more affordable GT 53.

5. The Dual-Motor AMG GT 53 Focuses on Lighter Weight and Accessibility

The other way to approach the electric performance of the Mercedes-AMG GT 53 SUV is to use a pair of conventional radial-flux permanent-magnet synchronous motors rather than three axial-flux motors. A direct-drive front motor and a two-speed automatic transmission-driven rear motor deliver 536 horsepower, 800 Nm of torque, and 362 horsepower of continuous power (as opposed to the GT 55 and GT 63’s higher-end figures). These deliver less oomph, but the two-motor setup slashes the GT 53’s weight by close to 400 pounds compared to its tri-motor siblings, and the vehicle weight reduction and ability of the powertrain to control it scales down the bottom end of the power band.

GT 53’s Lighter Performance Formula:

• Dual motors deliver 536 horsepower
• Maximum torque reaches 800 Nm
• Rear motor receives two-speed transmission
• Lighter weight improves driving agility
• European pricing starts at €113,050

The GT 53 has an estimated 0-60 mph time of 4.1 seconds, or 3.7 seconds with a one-foot rollout. Its lighter overall weight and lighter front end should make the GT 53 more nimble through snappy corners. Unlike the more powerful tri-motor models that favor acceleration, the GT 53 is focusing on a unique blend of power and efficiency. The electric SUV also uses a smaller 106 kWh of usable battery pack as it will have different specification from the larger-battery GT 55 and GT 63. Germany-based order books will open October 20 with prices from €113,050; pricing in the US could be in the low $130,000 range. Two motors and a less extensive battery make the GT 53 the more entry level AMG 4Matic+ electric SUV.

6. Advanced Battery Technology Supports Impressive Range and Rapid Charging

AMG GT SUV requires unique battery system AMG engineers had to design an extremely innovative battery system, as the high power while necessarily came with the implication that heat had to be dissipated during normal operation. The resulting 800-volt high-performance battery was made up of a battery housing with cylindrical cells, equipped with NCMA (nickel, cobalt, manganese, aluminium) cathodes and silicon in the anodes. The cell specific energy density is in excess of 298 Wh/kg which means storing enough energy. Cell cooling is extremely important, especially since it has to be repeated again and again with each acceleration and high-power driving. Each cell is directly immersed in non-conductive cooling oil inside the battery pack.

Battery Engineering and Thermal Control:

• High-performance battery uses 800-volt architecture
• Cylindrical cells feature advanced NCMA cathodes
• Silicon anodes support energy density
• Individual cells receive direct oil cooling
• Two battery capacities serve variants

Two variants, the GT 55 and GT 63, are equipped with a 22-module battery providing 128 kWh of net energy content, while the GT 53 has an 18-module pack with 106 kWh of usable energy. The additional capacity of the larger battery pack provides for energy demand of the tri-motor drive systems and supports charging rates of up to 710 kW in optimal conditions. The smaller pack of the GT 53 supports a peak DC charging rate of 600 kW. Actual charging times depend on the charger used, the temperature of the battery, as well as the state of vehicle’s and battery’s temperature, gas pedal and charger. With 800-volt architecture, high energy density and directly cooled cells AMG has made the battery a focal point for high electrical power.

7. The Electric GT SUV Combines Long Driving Range With Ultra-Fast Charging

Although it has full-sized SUV body style, Mercedes-AMG also set the GT SUV to have good driving range. Both GT 55 and GT 63 are planned to make use of their 128 kWh of batteries for an estimated 620-700 km (385-435 miles) of WLTP range. The SL55 53 only delivers 597-668 km (371-415 miles), but its use of the traditional radial-flux motors is also helping, Mercedes-AMG said. Although it is not a WLTP estimate, the range based on the car’s expected U.S. EPA rating should be very close when the car arrives in the 2027-time frame. The AMG GT has a great deal of muscle to pace it and still covers some range, in part thanks to the shape making for a chunky body and form, meaning some added drag.

Range and Charging Performance Highlights:

• GT 63 range reaches 435 miles
• GT 53 range reaches 415 miles
• Charging peaks at 710 kW
• Ten-to-eighty percent takes twelve minutes
• Five charging standards receive native support

Speaking of speed, it’s also fast. The GT 55 and GT 63 versions with the 128 kWh batteries top out at 710 kW for DC charging rate, which delivers a 10-80% charge in 12 minutes (considering optimum conditions). The same 10-minute stop provides 454 km of WLTP range (about 282 miles) at optimum conditions. The GT 53 charges at up to 600 kW; it takes 11 minutes for the same 10-80% charge. Mercedes makes five charging standards available natively, one of which is the North American Charging Standard (NACS), giving access to Tesla Supercharger stations with no need for the cumbersome adapters, though you can’t reliably get the 710 kW rates on most North American charging stations; many are 400 kW. Even on lower-powered chargers, the system is designed to make charging stops convenient.

8. Advanced Suspension, Rear-Wheel Steering, and Aerodynamics Control the SUV’s Weight

To deliver this level of agility in an SUV weighing 2.7 tonnes (6, 0 lb) requires a lot of sophisticated chassis technology. The individual AMG SUVs in the GT SUV portfolio are available with rear-axle steering, which can turn the rear wheels up to six degrees. In the lower speed range, the rear wheels turn in the opposite direction to the front wheels, considerably reducing the turning circle of the SUV. At high speed, the rear wheels turn in the same direction as the front wheels, increasing directional stability and agility when changing lanes. The most powerful model in the new GT SUV portfolio, the GT 63, comes with AMG Active Ride Control+ suspension technology based on the AMG GT 4-Door as standard. This suspension system replaces conventional mechanical anti-roll bars with three-chamber air springs.

Chassis Systems Designed for Control:

• Rear steering reaches six degrees
• Active hydraulics reduce body roll
• Three-chamber air springs support stability
• Drag coefficient measures just 0.27
• Active spoiler generates high-speed downforce

Active aerodynamics enhance the efficiency and handling of the GT SUV. The drag coefficient for the GT SUV is just 0.27 remarkable for a performance crossover with a length of 5,084 millimeters, width of 2,001 millimeters and height of 1,656 millimeters. When driving, the active aero shutters at the front open and close in the cooling ducts to regulate the flow of air through the radiator grille and the channels in the underbody depending on the vehicle’s speed and the temperature of the various components. At the rear, the active roof spoiler automatically extends when the vehicle exceeds 93 mph and does so increasing the aerodynamic efficiency and adding downforce. With a wheelbase of 3,040 millimeters, short overhangs and wide tracks, the proportions and appearance of the vehicle are both optimized.

9. A Digital Luxury Cabin Combines Family Practicality With Synthetic AMG Sound

Below the instrument cluster and integrated into the dash’s flow is a 10.2‑inch cluster and a 14‑inch central touchscreen that is loaded with Mercedes’ latest automotive software package. An optional 14‑inch passenger display is also available giving the cabin the feeling of a massive digital cockpit. Inside diamond‑quilted leather upholstery and carbon‑fiber interior accents help keep the premium and performance controls remain driver‑centric. And the “engine” of the model is a three‑knob AMG Race Engineer rotary controller, for adjustments of power response chassis agility and traction‑control levels in addition, to AMG screens offering real‑time telemetry lap‑times and track‑data recording and a wireless charging tray.

Interior Technology and Practical Features:

• Digital cockpit features dual-screen displays
• Optional passenger screen measures fourteen inches
• AMG controls adjust performance settings
• Rear seats provide generous passenger space
• Cargo capacity reaches 1,740 liters

The GT SUV is more practical than the slung sedan version. By fitting the battery into the AMG.EA floor it creates deep footwells and gives everyone a tall upright seating position. All five people in the car have plenty of legroom and headroom. Rear passengers get heated, adjustable seats and a standard panoramic glass roof. There’s 607 liters of cargo space behind the row. When you fold down the seats that space grows to 1,740 liters. There’s also a storage compartment with 78 liters and another 111-liter storage area under the hood. AMG made the AMGFORCE Sport+ synthetic sound system for drivers who still miss the noise of gas engines. The GT 55 and GT 63 play a V8 engine sound. The GT 53 uses a six-cylinder engine sound. The system adds gearshift sounds, engine rumble at idle and small vibrations, in the seats to make it feel real. If you don’t like the artificial noise, you can turn it off with Silent mode.

10. AMG GT 63 Takes Aim at Porsche’s Electric Cayenne

The Mercedes-AMG GT 63 SUV is entering a water-crowded market where electric vehicles are eating into every caveat of combustion performance vehicles. Its main competitors are obvious: Porsche Cayenne Turbo Electric, 1,139 hp and 0-to-60-mph time in a footrollout comparable with the AMG. The Mercedes is argued on paper to have a few notable benefits. Its 128-kWh battery is bigger than the Cayenne Turbo Electric’s 113-kWh one. And its theoretical max charging rate of 710 kW beats the plug-in Porsche’s 400 kW limit. But, unless the Mercedes is plugged into an infrastructure that can support its capacity and the underlying conditions are suitable, that power difference could simply mean shorter charging stops – a vital consideration for adoption but probably not for the buyer.

Competition and Market Positioning:

• Porsche Cayenne Turbo Electric produces 1,139 horsepower
• AMG battery capacity reaches 128 kWh
• Theoretical charging peak reaches 710 kW
• BMW electric X5 M expected around 2028
• U.S. deliveries begin summer 2027

BMW is also planning a X5 M competitor, expected around 2028 together with the regular V8 models. In response to this competition Mercedes-AMG is putting the GT SUV in the spotlight as an early player, in the ultra-high‑performance electric SUV market. Mercedes-AMG will begin deliveries in early 2027 and U.S. Dealers will get the 2028 model in summer 2027. The GT SUV uses axial‑flux motor technology, an 800‑volt battery, fast charging, active hydraulic suspension and a roomy five‑seat cabin giving it advantages. Mercedes-AMG offers three versions: the lighter dual‑motor GT 53 the powerful GT 55 and the flagship GT 63. In short, the GT SUV shows how electric design can match speed with family‑friendly space and luxury as charging networks and performance tech keep improving.
