Mercedes-Benz has unveiled an electric SUV with enough horsepower to rival some of the world’s fastest supercars and a charging system that pushes well beyond the capabilities of Canada’s established public charging networks.
Revealed on October 17, 2026, the new Mercedes-AMG GT SUV produces up to 1,153 horsepower and supports DC fast charging at an extraordinary 710 kilowatts. Under ideal conditions, Mercedes says its largest battery can recharge from 10% to 80% in just 12 minutes.
There is one complication for Canadian drivers. Even some of the country’s newest high-powered public chargers are rated at 400 kilowatts, leaving a substantial gap between the vehicle’s engineering capabilities and the infrastructure available to support them.
The announcement offers a glimpse of the next generation of electric performance while raising questions about how quickly Canada’s charging infrastructure can catch up.
Mercedes-AMG Has Developed Its First SUV Entirely From Scratch
The new Mercedes-AMG GT SUV represents a significant milestone for the German performance division. Although AMG has spent decades producing high-powered versions of Mercedes-Benz SUVs, this is the first full-size SUV engineered entirely in-house by AMG. Built on the dedicated AMG.EA electric architecture, it shares its technological foundation with the recently introduced electric AMG GT 4-Door Coupe. Rather than modifying an existing gasoline-powered SUV, engineers developed the vehicle around electric motors, a high-voltage battery and sophisticated electronic driving systems.
Mercedes has announced three versions: the AMG GT 53 SUV, GT 55 SUV and range-topping GT 63 SUV. The entry model produces 536 horsepower, while the GT 55 raises output to 805 horsepower. The GT 63 delivers the headline-grabbing 1,153 horsepower. These figures give customers different levels of performance without abandoning the model’s all-electric identity. Mercedes has confirmed that the 2028-model-year SUV will arrive at U.S. dealerships in summer 2027. Canadian pricing and delivery dates have not yet been officially announced.
The 1,153-Horsepower GT 63 Produces Extraordinary Performance
The AMG GT 63 SUV uses three axial-flux electric motors, with two driving the rear axle and another positioned at the front. This configuration produces a combined peak output of 1,153 horsepower and 1,475 pound-feet of torque. Mercedes estimates acceleration from zero to 60 mph in 2.4 seconds using a one-foot rollout measurement, or approximately 2.6 seconds without that adjustment. Its electronically limited top speed reaches 168 mph, equivalent to roughly 270 km/h. Those figures are remarkable for a full-size SUV weighing approximately 2,695 kilograms.
However, peak horsepower should not be confused with continuously available power. Mercedes lists the GT 63’s sustained output at 711 horsepower, with its highest performance available during limited boost periods. That distinction matters because electric motors and batteries produce considerable heat under intense acceleration. The company designed the drivetrain to provide repeatable performance rather than an impressive figure that can only be achieved once. Most owners will never approach those limits on public roads, but the engineering demonstrates how manufacturers are using electric power to redefine what large luxury vehicles can accomplish.
Its 800-Volt Battery Uses Technology Inspired by Formula 1
The vehicle’s charging and acceleration capabilities depend heavily on its battery architecture. Mercedes has developed an 800-volt system with two usable battery capacities: 106 kilowatt-hours for the AMG GT 53 and 128 kilowatt-hours for the GT 55 and GT 63. The larger battery contains 22 modules and is designed to deliver extremely high levels of power during acceleration and charging. Its cylindrical cells use nickel-cobalt-manganese-aluminum chemistry with silicon-containing anodes, providing high energy density and low internal electrical resistance.
A particularly unusual feature is the battery’s direct cooling system. Instead of relying exclusively on conventional cooling plates, Mercedes circulates electrically non-conductive oil around individual battery cells to manage heat. The manufacturer says this approach helps maintain consistent temperatures and supports repeated high-power operation. A centralized coolant management system also directs cooling capacity toward the motors and other components when necessary. These innovations are important because accepting electricity extremely quickly generates substantial heat. Without effective thermal management, the battery would need to reduce charging power to protect itself, limiting the usefulness of an exceptionally powerful charging station.
Mercedes Promises a 12-Minute Charge and Up to 700 Kilometres of Range
Charging performance is arguably the vehicle’s most ambitious feature. Mercedes says the 128-kWh versions can accept up to 710 kilowatts of DC power at suitable 800-volt charging stations. Under specified test conditions, they can recharge from 10% to 80% in approximately 12 minutes. The company also claims that a ten-minute session can add as much as 454 kilometres of estimated driving range under the European WLTP testing cycle. The smaller-battery GT 53 supports up to 600-kW charging and can complete a comparable 10%–80% session in approximately 11 minutes.
Mercedes projects between 620 and 700 kilometres of WLTP combined range for the GT 63 and GT 55, depending on configuration. These are preliminary manufacturer figures, not independently verified Canadian ratings. Actual range will depend on driving speed, weather, road conditions, vehicle configuration and energy consumption. A driver accelerating aggressively or travelling long distances in freezing temperatures should not expect the laboratory maximum. Nevertheless, the combination of a substantial battery and exceptionally fast charging could eventually reduce the inconvenience of long-distance electric travel—provided drivers can find equipment capable of delivering the required power.
Canada’s Established Charging Networks Fall Short of 710 Kilowatts
The gap between the new SUV and Canada’s charging infrastructure is significant. Mercedes-Benz launched its own Canadian High-Power Charging network in January 2026, introducing locations around Metro Vancouver with chargers rated at up to 400 kilowatts. BC Hydro has also installed 400-kW equipment at locations including Burnaby and Nanaimo. Meanwhile, Canadian charging company FLO reported in April that more than 150 of its fast-charging stations were capable of delivering power in the 320-to-480-kW range. Those are substantial improvements over older charging stations, but none matches the Mercedes SUV’s 710-kW maximum.
Compared with a 400-kW charger, the GT 63’s peak charging capability is 310 kilowatts higher, or approximately 77.5% greater. Even a 480-kW unit remains 230 kilowatts below the vehicle’s maximum. That does not establish that every public charger in Canada has been individually checked or that a future ultra-high-power installation is impossible. It shows that the new Mercedes exceeds the documented capabilities of several major Canadian passenger-EV charging networks. The technological challenge is increasingly shifting from what premium electric vehicles can accept to what roadside charging equipment can reliably supply.
Charging at 400 Kilowatts Would Still Be Surprisingly Quick
The gap between vehicle capability and charger capacity sounds dramatic, but the practical difference may be smaller than expected. Mercedes has published charging estimates for stations limited to 400 kilowatts. Under its specified conditions, the GT 63 and GT 55 can recharge from 10% to 80% in approximately 16 minutes using that equipment, compared with 12 minutes at their maximum charging capability. The smaller GT 53 takes approximately 14 minutes at a 400-kW station, rather than its best-case 11-minute figure.
That is an important distinction for Canadian drivers. A four-minute difference matters to an automaker competing on technical performance, but a 16-minute stop could still be convenient during a long highway journey. Real-world charging may take longer, however, because a charger’s advertised kilowatt rating represents a maximum rather than guaranteed power throughout the session. BC Hydro, for example, says some of its 400-kW chargers can divide available power between two connected vehicles, providing up to 200 kilowatts each. Battery temperature, state of charge and equipment limitations can further affect charging time.
Canada Has Thousands of Chargers, but Most Are Not Ultra-Fast
Canada’s public charging network continues to expand, although the total number of charging ports does not reveal how quickly vehicles can recharge. Transport Canada’s EV dashboard, updated in August 2026 with information through March, records 39,220 publicly available charging ports nationwide. Of those, 30,741 are Level 2 chargers and 8,479 are Level 3 fast chargers. That means approximately 78% of the recorded infrastructure consists of slower Level 2 equipment, generally intended for longer parking periods rather than brief highway stops.
The growth rate remains encouraging. Electric Autonomy’s April 2026 charging-network assessment reported a 17.4% annual increase in Canada’s total public charging infrastructure, with DC fast-charging installations growing more rapidly than Level 2. Tesla also indicated plans to begin deploying next-generation V4 charging cabinets capable of delivering more than 500 kilowatts in Canada during 2026. However, planned installations should not be confused with verified operating capacity. For a future AMG owner travelling between major Canadian cities, charger location, connector compatibility, reliability and actual power delivery will matter more than the national total alone.
Canadian Winters Could Reduce Range and Slow Charging
Cold weather presents another challenge that manufacturer charging demonstrations cannot fully capture. In February 2025, the Canadian Automobile Association conducted a real-world winter evaluation of popular electric vehicles between Ottawa and Mont-Tremblant. Testing took place in temperatures ranging approximately from minus 7 to minus 15 degrees Celsius. The participating vehicles travelled between 14% and 39% less distance than their published Canadian range estimates. Those results varied considerably by model, demonstrating that winter performance depends on vehicle design and battery management.
The new Mercedes-AMG GT SUV was not included in that testing, so its own cold-weather range remains unknown. Its advanced battery cooling and thermal management systems may help control operating temperatures, but they do not eliminate the energy required to heat a battery or passenger compartment. The U.S. Department of Energy recommends battery and cabin preconditioning to improve winter EV performance. For Canadians travelling during January or February, the difference between a warm battery arriving at a high-powered charger and a cold battery arriving without preparation could be important. Independent winter testing will be necessary before Mercedes’ charging claims can be translated into dependable Canadian travel expectations.
Mercedes Wants Supercar Performance Without Sacrificing SUV Comfort
Beyond charging technology, Mercedes has attempted to combine extreme acceleration with the everyday practicality expected of a luxury SUV. The GT 63 includes AMG ACTIVE RIDE CONTROL+, an advanced suspension system designed to reduce body roll and pitching movements. Rear-axle steering improves manoeuvrability, while active aerodynamic elements adjust airflow according to speed and driving conditions. The GT 63 also features a low drag coefficient of approximately 0.27, an impressive figure for a vehicle with substantial interior space and performance-oriented bodywork.
Inside, the vehicle includes a 14-inch central multimedia screen, a 10.2-inch driver display and an optional 14-inch passenger screen. The cabin provides seating for five, with approximately 21.4 cubic feet of rear cargo space and a small front storage compartment. Mercedes has also introduced simulated AMG engine sounds, artificial gear changes and seat vibrations for drivers who miss the sensation of traditional performance cars. These features can be adjusted, including a quieter driving setting. The result is an unusual combination: a family-capable electric SUV designed to deliver sports-car acceleration while retaining comfortable seating, luggage capacity and familiar luxury features.
Canadian Pricing and Availability Remain Unanswered Questions
Mercedes has confirmed that production will take place at its Sindelfingen manufacturing facility in Germany, with U.S. dealership deliveries scheduled for summer 2027 as a 2028 model. The manufacturer’s Canadian media website published images of the AMG GT SUV on October 17, but a specific Canadian on-sale date, official Canadian pricing and final domestic specifications have not been confirmed. That makes it premature to estimate what the vehicle will cost at Canadian dealerships or assume that the full lineup will arrive simultaneously.
The charging network may look different by the time the SUV reaches customers. Tesla is pursuing higher-powered charging equipment, Mercedes is expanding its own charging operations, and BYD has outlined plans for megawatt-class charging technology in Canada. Yet proposed infrastructure must still be installed, connected to the electricity grid and made compatible with the vehicles intended to use it. For prospective AMG buyers, the key developments will be confirmed Canadian delivery plans, independent range testing and the availability of suitable charging stations. The new Mercedes demonstrates how quickly electric-vehicle technology is advancing. Canada’s challenge is ensuring that the infrastructure supporting those vehicles advances alongside it.
