The landscape of the high-performance automotive world is undergoing a seismic shift, and Mercedes-AMG is positioning itself at the epicenter of this transformation. In a move that signals a new chapter for the Affalterbach-based performance division, the company has officially unveiled the 2028 Mercedes-AMG GT SUV. This is not merely an electric version of an existing product; it represents the first full-size SUV developed entirely in-house by AMG, bringing the brand’s storied sports car DNA into the burgeoning segment of ultra-high-performance electric utility vehicles.
With the arrival of the GT SUV, Mercedes-AMG is making an uncompromising statement about the future of power. The flagship variant of this new model line boasts a staggering output of up to 1,153 horsepower, allowing it to rocket from a standstill to 60 miles per hour in a mere 2.4 seconds. These figures place the GT SUV in a rarified atmosphere, challenging not just other electric SUVs, but some of the most capable supercars on the planet. Beyond raw acceleration, the vehicle introduces industry-leading charging technology, capable of DC fast charging at rates of up to 710 kilowatts, effectively addressing one of the primary concerns of the modern EV era: the time spent at the plug.
The 2028 Mercedes-AMG GT SUV is the second vehicle to be built upon the brand’s dedicated AMG.EA (AMG Electric Architecture) platform. This bespoke performance foundation follows in the footsteps of the recently revealed AMG GT 4-Door Coupe, proving that AMG is committed to a ground-up approach for its electric future rather than relying on modified versions of standard Mercedes-Benz luxury platforms. By controlling the development from the chassis up, AMG engineers have been able to integrate specialized performance components that would otherwise be impossible to package in a traditional SUV.
A Trio of High-Performance Models
When the Mercedes-AMG GT SUV arrives at United States dealerships in the summer of 2027, customers will be presented with three distinct tiers of performance: the GT53 SUV, the GT55 SUV, and the range-topping GT63 SUV. Each model is designed to offer a different balance of daily usability and track-ready capability, though all three maintain the aggressive persona expected of the AMG badge.
The powertrain configurations vary significantly across the lineup. The GT55 and GT63 models utilize a sophisticated three-motor setup, featuring one electric motor on the front axle and two at the rear. This layout allows for incredible precision in power delivery. For instance, the front motor is designed with efficiency in mind; it can completely decouple when not required, reducing mechanical drag and conserving energy during steady-state cruising. However, the moment the driver demands extra traction or a burst of acceleration, the front motor kicks back in instantaneously.
In contrast, the entry-level GT53 SUV employs a more traditional dual-motor approach, with one motor dedicated to each axle. To maximize its performance envelope, the GT53 is equipped with a unique two-speed transmission at the rear axle. This hardware choice mirrors the strategies used by some of the world’s most advanced electric sports cars, utilizing a shorter first gear to provide explosive off-the-line acceleration and a taller second gear to ensure high-speed efficiency and sustained power during highway driving.
Regardless of the motor count, all three models come standard with the AMG Performance 4MATIC+ all-wheel-drive system. In the three-motor GT55 and GT63 variants, this system is further enhanced by the ability to send power to individual rear wheels. This torque vectoring capability allows the SUV to rotate more effectively through corners, effectively shrinking the feel of its full-size footprint and providing the kind of handling agility usually reserved for much smaller vehicles.
The performance hierarchy is clear when looking at the numbers. The GT53 SUV offers a continuous output of 362 horsepower, but it can reach a peak of 536 horsepower and 590 lb-ft of torque. This allows for a 0-60 mph sprint of 4.1 seconds and a top speed of 143 mph. Moving up to the GT55 SUV, the continuous output jumps to 711 horsepower, with a peak performance of 805 horsepower and a massive 1,372 lb-ft of torque. This model slashes the 0-60 mph time to 3.0 seconds flat and increases the top speed to 168 mph. Finally, the GT63 SUV represents the pinnacle of the range. While it shares the 711 horsepower continuous output, its peak performance is unlocked at a monstrous 1,153 horsepower and 1,475 lb-ft of torque, enabling that headline-grabbing 2.4-second 0-60 mph time.
