Mercedes-AMG is preparing to shake up the performance SUV segment with the arrival of the 2028 Mercedes-AMG GT SUV, the brand’s first sports utility vehicle developed entirely in-house by its AMG division. This three-model lineup represents a major milestone for the automaker and signals a dramatic shift in how premium electric performance vehicles will look and perform when they hit showrooms next summer.
A New Era of Performance SUV Technology
The standout model is undoubtedly the GT63, which delivers a staggering 1,153 peak horsepower through a three-motor electric powertrain. That translates to acceleration from zero to 60 miles per hour in just 2.4 seconds, making it competitive with some of the fastest vehicles on the market today. The GT55 sits in the middle with 805 peak horsepower and sustained output of 711 horsepower, while the entry-level GT53 uses a more traditional two-motor setup producing 536 peak horsepower.
What makes this technology particularly noteworthy is Mercedes-AMG’s mastery of axial-flux electric motors. These motors were previously reserved for ultra-exclusive hypercars like the Ferrari 296 GTB and Lamborghini Revuelto, largely because manufacturing them at scale has proven extremely challenging. Mercedes invested heavily in making this technology more cost-effective, and now it appears as the centerpiece of the GT55 and GT63 models. The GT55 and GT63 feature two rear motors handling propulsion and torque vectoring, with an additional front motor providing extra power when needed.
Battery and Range Considerations for Shoppers
The GT55 and GT63 models come equipped with an 800-volt battery pack containing 22 modules and a usable capacity of 128 kilowatt-hours, representing a 22 percent increase over the sedan version. The GT53, however, uses an 18-module battery like the sedan, which weighs nearly 400 pounds less. Despite having the smaller battery, the GT53’s more efficient standard electric motors mean its driving range may not differ significantly from the heavier GT55 and GT63 models.
Current estimates suggest the GT53 SUV could achieve approximately 300 miles of range, similar to the sedan version. The GT63 SUV, thanks to its larger battery, may offer comparable or slightly better range than its sedan counterpart, despite its boxier shape creating more aerodynamic drag. This practical battery sizing approach gives shoppers options based on their budget and driving needs.
SUV-Specific Features and Interior Comfort
Mercedes-AMG engineered this vehicle specifically for SUV buyers, not simply adapting a sedan design. The higher ride height and increased seating position create different driving dynamics than a sedan, so the engineers developed an upgraded AMG Active Ride Control Plus suspension system. This system includes active roll and pitch stabilization technology, with interconnected front and rear axles designed to minimize acceleration squat and braking dive. Three-chamber air springs are recalibrated specifically for SUV use.
Inside, the GT SUV offers significantly more rear-seat legroom than its sedan sibling. Passengers will find abundant headroom and comfortable foot space without sacrificing storage for battery components. As other luxury brands reveal their own electric SUV strategies, the spacious interior and practical comfort of Mercedes-AMG’s offering becomes a key selling point. The front cabin closely mirrors the sedan’s layout, with the driver-focused angled screen and the three-knob AMG Race Engineer controller for adjusting response, agility, and traction settings.
Performance Tradeoffs and What Matters Most
One important distinction: the sedan GT63 reaches 60 miles per hour in 2.0 seconds, while the SUV takes 2.4 seconds due to its increased weight and aerodynamic drag. This 20 percent slower acceleration reflects the real-world physics of the taller, boxier body shape. For most buyers, however, 2.4 seconds represents extraordinary acceleration, and when comparing performance SUVs in today’s market, few competitors offer anything close to this level of performance.
The GT55 and GT63 produce 1,372 and 1,475 pound-feet of torque respectively, delivering overwhelming pulling power. For those seeking a more accessible entry point, the GT53 offers substantial capability at a lower price point, potentially starting below $130,000 compared to higher trim levels.
When Will It Arrive and What Comes Next
The 2028 Mercedes-AMG GT SUV becomes available next summer, though Mercedes has not yet released final pricing, official range figures, or consumption data. The GT55 and GT63 will command premium pricing compared to their sedan equivalents, positioning the GT53 as the value play in the lineup. This tiered approach ensures that performance-minded SUV shoppers have options whether they prioritize maximum power or overall value.
For buyers seeking the ultimate in performance and technology, this vehicle represents a significant achievement in electric SUV engineering, combining three-motor efficiency with proven automotive luxury and practical family-friendly interior space.
