Mercedes-AMG has just revealed images of two heavily camouflaged race-bred machines featuring red and yellow highlights at the Nüburgring. Seen here are the upcoming AMG GT3 and a new AMG GT Black Series, and they are being developed side by side from the same core idea.
It serves a specific purpose as the homologation model for AMG’s next-generation GT3 contender. Motorsport regulations require a production-based platform, and Mercedes-AMG is responding with a street car engineered to meet that standard from the outset. The result is a tightly linked program where lessons from endurance racing directly shape the street-legal flagship.

"We are developing the most extreme Black Series ever. At the same time, we want to set the next record-breaker in motorsport with the future GT3. The foundation for this is the CONCEPT AMG GT TRACK SPORT – a technology demonstrator that was more than just a concept from the very start. At AMG, we develop vehicles to exceed expectations. And that is exactly what the future Black Series and the new GT3 will do." - Michael Schiebe, Member of the Board of Management of Mercedes-Benz Group AG.
For some context, the last AMG GT Black Series, with its flat-plane crank 4.0-liter twin-turbo V8 and 720 horsepower, recorded a 6:43.616 lap around the Nürburgring, at the time the fastest lap for a production car.
The groundwork traces back to the Concept AMG GT Track Sport, first shown last year as a preview of the most extreme interpretation of the current AMG GT Coupe. That concept now transitions into reality, forming the technical backbone for both the GT3 race car and the new Black Series. Recent testing activity confirms the pace of development.
Since October 2025, camouflaged prototypes have undergone intensive evaluation across multiple circuits across Europe, like Portimao, before arriving at the Nürburgring Nordschleife as seen here.
Both cars also reveal key design and functional elements. Dominating the rear is a massive swan-neck-mounted wing, signaling a serious focus on downforce and high-speed stability. Up front, the Black Series appears to feature a Panamericana grille, flanked by an aggressive front fascia with pronounced canards.
The hood incorporates a central scoop with perforated sections on either side, likely aiding heat extraction and airflow management. Along the flanks, side-mounted exhaust outlets hint at a more extreme, track-oriented setup, while both cars sit on center-lock wheels wrapped in Michelin Pilot Sport Cup 2 tires, reinforcing their circuit-first priorities.
“With the unveiling of the concept, we can now officially name the new Mercedes-AMG GT3, with which we aim to continue the success story in Customer Racing for Mercedes-AMG Motorsport. Our goal is to once again present a vehicle that sets the benchmark. We have already gained important insights from the initial tests. We are now entering the next phase of development and will also be testing on race tracks relevant to GT Sport." - Christoph Sagemüller, Head of Mercedes-AMG Motorsport.
Looking back, Mercedes-AMG’s customer racing initiative began in 2010, followed by a full GT3 campaign with the SLS AMG GT3 in 2011. The AMG GT3 replaced it in 2016, with the Evo specification introduced in 2020.
The formation of Affalterbach Racing GmbH marks the next phase, working alongside Mercedes-AMG Motorsport to develop and build the successor. The Black Series lineage, meanwhile, dates back to 2006 with the SLK 55 AMG, which at one point was deployed as an FIA Formula 1 Safety Car. Mercedes-AMG states that further details will follow at a later date.
