Mercedes-AMG has confirmed the return of the GT Black Series, and this time it's being developed in lockstep with the next-generation GT3 race car. The road car will serve as the homologation base for the racer, putting it in direct competition with the Porsche 911 GT3 RS and Ford Mustang GTD.
The company released teasers of what it calls the Concept AMG GT Track Sport, the same prototype spotted testing at the Nurburgring Nordschleife in heavy camouflage. Two versions are running simultaneously: one destined for GT3 competition, the other for the road. Small grille differences aside, the silhouettes are nearly identical.
🏁 Active Aero Borrowed from the AMG One
The bodywork takes clear inspiration from the Mercedes-AMG One hypercar. Active aero flaps sit above the front wheels, joined by a massive front splitter, canards, a vented hood, and a swan-neck rear wing that stretches from where the rear window would normally be. There is no rear window. Instead, a solid panel supports the wing's uprights, similar to the Manthey kit for the 911 GT3 RS.
Out back, a deeply sculpted diffuser and side-exiting tailpipes complete the picture. The overall shape retains the AMG GT's greenhouse, but the Track Sport is noticeably longer and wider, with completely redesigned rear bodywork and aggressive aero add-ons at every corner.
🔧 Flat-Plane Crank V8, No Hybrid
Unlike the GT 63 S E Performance, which pairs its V8 with a plug-in hybrid system, the Black Series project focuses entirely on lightweight, naturally aspirated (or high-revving forced-induction) performance. Under the hood sits a new iteration of AMG's flat-plane crank V8, though Mercedes hasn't released power figures yet. Expect the output to land well above the previous Black Series' 720 hp, given the homologation intent.
The chassis is being developed across multiple circuits. AMG started at its in-house Immendingen facility, then moved to Bilster Berg, Portimao, and Monteblanco before arriving at the Nordschleife for the current testing phase.
Road Car as Racing Homologation
The dual-development approach matters. Building the road car to satisfy GT3 homologation requirements means AMG isn't just bolting aero onto a grand tourer and calling it a day. The entire structure, from the chassis to the aerodynamic package, needs to meet FIA racing specifications. That typically translates to a car that's stiffer, lighter, and more aerodynamically efficient than anything in the standard lineup.
Mercedes hasn't confirmed pricing, production numbers, or a launch date. But the GT3 racing calendar offers a clue: if AMG wants to compete in the 2027 GT3 season, the homologation car needs to be production-ready by late 2026. The previous GT Black Series started at $325,000. Expect this one to cost significantly more.
