New Mercedes-AMG GT3

What do the test pictures show?

Mercedes-AMG has released images of the Concept AMG GT Track Sport during track testing for the first time. The pictures show a heavily camouflaged bolide reminiscent of test runs on Bilster Berg. In the press statement, Mercedes talks about ‘first fahrdynamic challenges’ and calls the vehicle a concept, not the final racing vehicle.

Interestingly, the test vehicle wears parts similar to the future model, but at the same time still shows many elements of the current GT3 model. This suits a so-called mule car: a test vehicle that combines new components with familiar ones.

Engineering, mule-car and looks

According to sources within Mercedes-AMG, Affalterbach Racing GmbH is working on the successor to the Mercedes-AMG GT3. That project began after HWA would no longer handle construction and development. A V8 turbo engine and an all-carbon monocoque are assumed for the new car.

An insider described the test vehicle as a “Frankenstein car” - not as a swear word, but as a technical description: mix of old and new. The roof, windows and wing mirrors, for instance, look a lot like the current model, but the nose section differs markedly. The grille is a lot smaller and the front splitter has a different structure. The bonnet now shows an air intake where previously there was an exhaust vent; this indicates air supply to an upper turbocharger.

Mercedes itself stresses that the concept focuses on maximum driving dynamics, intelligent lightweighting and optimised weight balance. The manufacturer also mentions ‚AMG-typical V8 antenna technology’ and a complex aerodynamic design.

• Development by: Affalterbach Racing GmbH
• Powered by: V8 turbo engine (AMG)
• Chassis: full carbon monocoque
• Test runs: visible on circuits such as Bilster Berg

Planning and statements of leadership

Mercedes-amg says it sees 2026 as a pure development year. A 2027 delivery to customer teams is considered ambitious; 2028 sounds more realistic. Thomas Jäger, responsible for DTM activities at Mercedes-AMG, says that this is a concept and that Mercedes will reveal when the time comes: «Until then, we will keep the excitement going.»

Michael Schiebe, who will soon switch to Mercedes-Benz AG as board member for production, quality and supply-chain, praised the team and said of the concept: «The future is going to be extreme.» Mercedes stressed that the tests are intended to validate systems and complex components under harsh conditions, without revealing further details.

In a nutshell, the released photos show a clear move towards a new GT3 car, but for now it remains a prototype with both existing and new parts. Don't expect final specifications yet until Mercedes fully reveals its plans.
