Mercedes Faces Uphill Task Replacing GT3 Icon
Mercedes-AMG is developing a new GT3 car, but replacing one of the most successful GT3 models ever built is proving far from straightforward. The outgoing AMG GT3, in service since 2016, has dominated worldwide endurance and sprint racing, yet its successor faces the dual challenge of evolving technology and a competitive GT3 landscape.
The forthcoming model will be the first major project from Mercedes’ recently established Affalterbach Racing (AFR) division, created in mid-2024 after the marque ended its 27-year collaboration with HWA. While official specifications remain under wraps, the new GT3 is expected to draw from the Concept AMG GT Track Sport and will feature an all-carbon-fibre chassis and a turbocharged V8 engine. Homologation is tentatively planned for 2027.
“We want to create a follow-up of our successful car, and we know that it’s not easy because this car is very successful and it’s well balanced – and this is a challenge we will face,” said Mercedes head of customer racing, Stefan Wendl.
The current AMG GT3 is based on the first-generation AMG GT (C190), itself the spiritual successor to the SLS AMG. Despite a 2020 mid-cycle refresh, Mercedes opted not to introduce a second evolution, unlike rivals Lamborghini and Audi. The launch of the second-generation AMG GT (C192) in 2023 complicated the development of a new GT3, as its 2+2 seating configuration prevents a straightforward competition derivative.
The AMG GT3’s pedigree is impressive: victories at the 24 Hours of Nürburgring and Spa-Francorchamps, titles in DTM and GT World Challenge Europe, and multiple IMSA SportsCar Championship wins in North America. Its legacy underscores the scale of the challenge for Mercedes.
“It’s so successful that maybe you can think about another 10 years – to go directly into youngtimer,” Wendl joked.
Mercedes acknowledges that the GT3 market has evolved. New entrants and accelerated update cycles, such as Ford’s Mustang GT3 Evo launching in 2026, have intensified competition. Affalterbach Racing will oversee the development and support of the new GT3, aiming to maintain customer satisfaction while improving service and incorporating racetrack learnings into the car’s design.
| AMG GT3 Highlights | Data |

| Debut | 2016 |
| Chassis | First-generation AMG GT (C190) |
| Engine | Naturally aspirated V8 (2020 Evo update: tuned) |

| Refresh | Mid-cycle update 2020 |
| Expected Successor | Based on Concept AMG GT Track Sport, homologation ~2027 |
With only its third GT3 car in development, Mercedes is taking a measured approach. Wendl emphasises the importance of timing:
“We take the time for the development which is necessary, and to launch it when it’s ready.”
The new GT3 will need to uphold the AMG GT3’s legacy while meeting the demands of a more competitive, diverse, and technically sophisticated GT3 field.
