Mercedes-AMG has unveiled its 2027 GT SUV lineup, featuring three distinct electric connfigurations. The range is headlined by the high-performance GT63 and includes a more accessible entry-level GT53 model.
Bringing Axial-Flux Motors from the Ferrari 296 GTB to the SUV
The 2027 Mercedes-AMG GT SUV represents a significant shift in how high-end electric powertrains are deployed. According to the report, the GT55 and GT63 models utilize axial-flux motors—technology previously reserved for exotic, low-volume hypercars like the Lamborghini Revuelto, the Lamborghini Temerario, and the Ferrari 296 GTB. While these motors have long been prized for their power density,they were historically too difficult to manufacture at a scale suitable for mass-market luxury vehicles.
By investing in lower-cost production methods for axial-flux technology, Mercedes-AMG is attempting to democratize a level of performance once exclusive to the most expensive cars in the world. This move signals a broader industry trend where the boundary between "hypercar" engineering and "luxury production" vehicles is blurring, allowing a family-sized SUV to share the same motor DNA as a mid-engine Italian masterpiece.
The 1,153-HP GT63 and the 2.4-Second Sprint
At the top of the hierarchy, the Mercedes-AMG GT63 SUV delivers a staggering 1,153 peak horsepower and 1,475 pound-feet of torque.. As reported by the source, this performance is achieved via a three-motor setup—two at the rear for propulsion and torque vectoring, and one at the front for additional thrust.. Despite this immense power, the GT63 SUV is estimated to hit 60 mph in 2.4 seconds, a figure slightly slower than the 2.0-second sprint of the GT63 sedan due to the SUV's higher aerodynamic drag.
To sustain this performance, the GT63 and the mid-tier GT55 (which produces 805 peak horsepower) utilize an 800-volt battery pack. This pack contains 22 modules, providing a usable capacity of 128 kWh.. This is a 22 percent increase over the 106 kWh battery found in the sedan version, a necessary upgrade to compensate for the SUV's 520-pound weight penalty and boxier profile.
How the GT53's 400-Pound Weight Advantage Affects Range
The entry-level Mercedes-AMG GT53 SUV takes a different engineering path, opting for traditional radial-flux permanent-magnet synchronous motors. This configuration uses only two motors—one direct-drive unit at the front and one at the rear with a two-speed automatic transmission—resulting in 536 peak horsepower. Because it lacks the complex tri-motor setup, the GT53 weighs nearly 400 pounds less than its more powerful siblings.
Interestingly, the GT53 may be the most efficient of the trio. Because radial-flux motors are more efficient than axial-flux units, the GT53's range is expected to be only about 4 percent lower than the tri-motor SUVs, despite using the smaller 106-kWh battery. This suggests the GT53 SUV could closely match the GT63 sedan's estimated 300-mile range, proving that weight reduction and motor efficiency can offset a larger battery capacity.
Taming the SUV's Height with AMG Active Ride Control Plus
To combat the inherent instability of a high-riding vehicle, Mercedes-AMG has introduced the AMG Active Ride Control Plus suspension. This system uses cross-linked dampers to stabilize body roll, pitch, and squat during aggressive acceleration and braking. The technology is an evolution of the system used in the GT63 4-door sedan, specifically tuned to handle the higher center of gravity found in the SUV.
The Missing Price Tags for the 2027 GT SUV
Despite the detailed technical specifications, several critical pieces of information remain missing. Mercedes-AMG has not yet announced the pricing for the GT53, GT55, or GT63 models, leaving it unclear how "affordable" the entry-level GT53 will actually be. Furthermore, while the AMG Active Ride Control Plus suspension sounds promising on paper, its real-world effectiveness remains unverified as the vehicle has not yet undergone public driving tests.
