Mercedes-AMG is well into development of its next flagship SUV, and recent spy sightings confirm this will be one of the most important vehicles the performance brand has launched in years. Still partially wrapped in camouflage, the prototype now reveals production-ready lighting elements and confirms this is a ground-up electric superSUV designed to sit above AMG’s current lineup. While official details remain limited, what’s already visible makes one thing clear: AMG is treating this as a true halo product, not just another high-output trim. Prototypes Point To A Purpose-Built Performance SUV HotCarsThe camouflaged test vehicles spotted on public roads and performance-testing routes show proportions and hardware that immediately set this SUV apart from existing Mercedes models. Wide tracks, oversized wheels, and massive brakes suggest a chassis designed for aggressive driving rather than comfort-first luxury. Earlier sightings have shown a charging port, reinforcing its fully electric layout. Importantly, the prototype does not appear to share proportions with the EQS SUV, reinforcing that AMG is building something distinct rather than modifying an existing platform.HotCarsThese spy shots give us a better look at the actual shape of the SUV, though most of it is still well hidden beneath the camo. The camouflaged prototype reveals a low, wide stance that immediately separates it from Mercedes’ existing SUVs. The roofline sits noticeably lower than a GLS or EQS SUV, giving the vehicle a planted, performance-focused posture. Large brakes are visible behind dark multi-spoke wheels, which hopefully means we need big brakes for crazy power. There are no exhaust outlets anywhere, reinforcing its fully electric layout. Captured during cold-weather testing, we like to think AMG is prioritizing handling and road presence over traditional SUV utility, which would make sense for them. The front daytime running lights are now visible and feature a slightly different design from those on the AMG GT4 EV, indicating that AMG is finalizing a distinct production identity. AMG’s Dedicated EV Architecture Sets The Foundation HotCarsUnderneath the camouflage, the SUV is expected to ride on AMG’s bespoke AMG.EA previewed by recent AMG electric concepts, though Mercedes has not yet confirmed platform details. The platform supports an 800-volt electrical system capable of charging at speeds exceeding 330 kW. This architecture was developed specifically for high-performance electric vehicles and supports an 800-volt electrical system, which is key for sustained power delivery and rapid charging. By using its own EV platform, AMG is signaling a clear separation from Mercedes-Benz’s mainstream electric models, allowing the performance division to tune dynamics, power delivery, and packaging without compromise. Direct competitors include the BMW XM, the upcoming Porsche Cayenne EV, and the Lamborghini Urus. Four-Figure Power Is The Target (Though Unconfirmed) HotCarsAMG has not confirmed output figures, but multiple credible reports suggest this SUV is being engineered with power levels that push well beyond anything currently offered by the brand. The SUV is widely reported to use axial-flux motors developed by YASA, which is central to that goal, offering high power density in a compact package. This approach positions the SUV squarely in the emerging electric super-SUV segment, aimed at future high-performance rivals rather than traditional luxury competitors. Final specifications remain under wraps, but AMG is targeting system output well beyond 1,000 horsepower, with figures as high as 1,360 hp expected. Regardless, this SUV is meant to redefine what an AMG performance vehicle looks like in the electric era.We've seen this SUV before, but hopefully, we're getting closer to actual confirmation of what's going on under that camo. With production details emerging and development nearing its final stages, this SUV is shaping up to define AMG’s future in electric performance rather than simply expand its lineup. The AMG GT super SUV is expected to debut later this year, with a full market launch planned for 2027.
