Mercedes-AMG GT SUV revealed as 1153bhp electric flagship

Mercedes-AMG has pulled the covers off its new high-performance AMG GT SUV, presenting an all-electric flagship designed to challenge established luxury electric performance vehicles. Revealed in Stuttgart according to Road & Track, the new vehicle represents the first full-size SUV developed entirely in-house by the Affalterbach performance division, utilising the dedicated AMG.EA electric vehicle architecture rather than sharing its underbones with existing Mercedes-Benz sport utility models. The launch marks a critical step for the brand as it translates its high-output performance ethos into the electric era.

Positioned as a direct rival to competitors like the Porsche Cayenne Electric, the GT SUV lineup comprises three distinct variations. According to primary reporting by Evo and Autocar, the flagship GT 63 and mid-tier GT 55 deploy a triple-motor configuration — featuring two axial-flux motors at the rear and a single motor up front equipped with a decoupling unit for enhanced highway efficiency. The entry-level GT 53 steps down to a conventional dual-motor layout.

Powering these setups are F1-inspired cylindrical battery cells featuring direct oil cooling. Product team lead Nadine Schütt explained to Auto Express that the vehicle is an SUV in shape but a GT by nature, engineered specifically to sustain high performance over extended driving periods without thermal degradation. While the GT 63 delivers a headline-grabbing 1,153bhp during launch or boost mode — available in lengthy 63-second bursts according to Evo, it maintains a continuous power output of 710bhp or 711bhp during normal operation. Charging capabilities are similarly extreme, supporting DC fast charging up to 710kW on the larger 128kWh battery pack, which allows drivers to replenish hundreds of miles of range in roughly ten minutes under ideal conditions.

Given the substantial mass of the vehicle, tipping the scales between approximately 2,585kg and 2,715kg depending on specification, AMG has integrated heavy physics-cheating technology. Standard on the GT 63 and optional on the GT 55 is the newly developed AMG Active Ride Control+ suspension. Schütt noted that the system provides both roll and pitch stabilization, actively keeping the car level under heavy acceleration and hard braking. Agility is further sharpened by up to 6 degrees of rear-wheel steering.

In terms of cabin atmosphere and emotional engagement, Mercedes-AMG has intentionally avoided a completely silent electric vehicle experience. The interior mirrors the driver-focused layout of its four-door coupe sibling, featuring angled screens, carbon central tunnel rotary controls, and an optional electrochromic panoramic glass roof. Furthermore, the GT 55 and GT 63 models incorporate the AMGForce Sport+ mode, generating artificial V8 exhaust noises through exterior and interior speakers alongside simulated gearshifts via steering-wheel paddles, as detailed by autoX.

Practicality remains a core advantage of the high-riding body style. The SUV provides a flat rear floor, accommodating up to 607 litres of luggage space with the rear seats upright, which expands to 1,740 litres when folded flat, complemented by a front storage compartment.

Market roll-out plans are already underway across Europe. The entry-level GT 53 variant goes on sale in Europe with prices starting in the region of £110,000 or €113,050, while the higher-tier GT 55 and GT 63 variants will follow. Official deliveries for initial specifications are scheduled to commence in the spring, with UK-specific pricing and final configuration details expected to be announced by Mercedes-AMG in the coming weeks.
