Performance in the electric age is defined as much by charging speed as it is by top speed. To that end, the AMG GT SUV utilizes a high-voltage 800-volt electrical system that sets new benchmarks for the industry. Depending on the model chosen, the vehicle is equipped with one of two high-density battery packs designed to handle extreme thermal loads and rapid energy discharge.
The charging capabilities are perhaps the most impressive technical feat of the GT SUV. The GT55 and GT63 models are capable of accepting a DC fast charge at up to 710 kilowatts. To put that into perspective, the GT55 and GT63 can add approximately 280 miles of range—based on the European WLTP cycle—in just 10 minutes of charging. Even the entry-level GT53 is a powerhouse in this regard, topping out at 600 kilowatts and adding 236 miles of WLTP-rated range in the same 10-minute window.
Range anxiety is further mitigated by the GT SUV’s efficiency. The GT63 is projected to offer a WLTP range of between 385 and 435 miles, depending on the specific configuration and wheel choices. While United States EPA estimates are often more conservative than WLTP figures and have not yet been finalized, these early numbers suggest that the GT SUV will be more than capable of handling long-distance journeys without frequent or lengthy interruptions.
Chassis Dynamics and the AMG Experience
Engineering a full-size SUV to handle like a sports car is a monumental task, particularly given the inherent weight of large battery packs. To solve this, Mercedes-AMG has deployed its new AMG Active Ride Control+ suspension system. Standard on the GT63 and available as an option on the GT55, this system replaces traditional mechanical anti-roll bars with a sophisticated network of hydraulic dampers and adjustable air springs.
By using hydraulics to interconnect the dampers, the system can instantly adjust the stiffness at each corner of the vehicle. This allows the GT SUV to remain remarkably flat during high-speed cornering and significantly reduces the "nose-dive" associated with heavy braking. Conversely, it can also limit body lift during hard acceleration, ensuring that the tires maintain an optimal contact patch with the road. Beyond the performance benefits, Mercedes-AMG emphasizes that this system actually improves ride comfort during casual driving, as it can decouple the wheels to better absorb bumps and road imperfections that would normally be transmitted through a rigid anti-roll bar.
For those seeking the ultimate level of control, the GT63 comes standard with the AMG Dynamic Plus Package (optional on the GT55). This package introduces the AMG Race Engineer Control Unit, which provides the driver with three dedicated rotary controls on the steering wheel. These allow for real-time adjustments to motor response, handling characteristics, and traction control, giving the driver the ability to fine-tune the vehicle’s behavior to suit the specific demands of the road or track.
Preserving the Emotional Connection
One of the greatest challenges for performance brands transitioning to electric power is the loss of the visceral auditory experience provided by a combustion engine. AMG’s solution is "AMGForce Sport+," a system designed to inject drama back into the driving experience through synthesized sound and physical feedback.
