The Mercedes-AMG GT R is the hardcore specification within the AMG GT line and the direct spiritual successor to the SLS AMG Black Series. Unveiled in June 2016 and delivered from 2016 to 2021, the GT R represents the peak of the M178 V8 biturbo within the AMG GT family: 585 hp from the 4.0-litre biturbo V8, rear-wheel drive via a seven-speed DCT gearbox, and factory-installed Active Aerodynamics with an extending rear wing. The GT R earned its nickname 'Beast of the Green Hell' due to its intensive development at the Nürburgring Nordschleife circuit (nicknamed Grüne Hölle or Green Hell). The line spans the original GT R coupé, the GT R Roadster (2019-2020, limited to 750 cars), and the GT R Pro (2018-2020, limited production hardcore specification). An AMG GT R is not sold to just any buyer; it is passed on to someone who knows the modern AMG track culture and values the difference between a GT S and a GT R Pro.
The Mercedes-AMG GT R was unveiled at the Goodwood Festival of Speed in June 2016 as the hardcore specification of the AMG GT line. AMG positioned the GT R explicitly as the direct spiritual successor to the SLS AMG Black Series, with the same philosophy: substantial power increase, factory-installed Aerodynamics Package, weight saving, and sharpened chassis for track performance. The 4.0-litre M178 V8 biturbo was uprated to 585 hp at 6,250 rpm, a 75 hp increase over the AMG GT S. Development was carried out intensively at the Nürburgring Nordschleife circuit, earning the car its nickname 'Beast of the Green Hell' (Green Hell is the English translation of Grüne Hölle, the German nickname for the circuit).
The GT R retained the 4.0-litre M178 V8 biturbo (internal engine code M178.980 for the GT R version) with new turbos, sharpened engine management, and revised exhaust for 585 hp. The seven-speed AMG SPEEDSHIFT DCT gearbox was uprated for faster shift times. Rear-wheel drive has factory-installed electronic locking differential with variable engagement. The key technical feature however is the factory-installed Active Aerodynamics: an extending rear wing that is electronically controlled for downforce or drag reduction depending on driving conditions, and factory-installed underbody elements that optimise airflow around the car. The nine-stage traction control (a dashboard knob that adjusts the level of electronic intervention) is a Ferrari manettino-style interface.
In 2018 Mercedes-AMG unveiled the GT R Pro as the most extreme regular GT R specification. Production was limited; exact numbers were not publicly disclosed. The GT R Pro retains the same 585 hp V8 but receives factory-installed AMG Coilover suspension (manually adjustable for different track settings), factory-installed Active Aerodynamics package with additional carbon canards, factory-installed rear wing, weight saving through more extensive factory carbon packs, and factory-installed lighter wheels. For track-oriented buyers the GT R Pro is the most sought-after regular GT R specification and consistently higher priced than regular GT R coupés.
In June 2019 Mercedes-AMG unveiled the GT R Roadster, limited to 750 cars worldwide. The Roadster retains the same 585 hp V8, Active Aerodynamics, and nine-stage traction control as the coupé, with an electric soft-top roof mechanism. The production numbers (750 cars) make the Roadster substantially scarcer than the regular GT R coupé. For collector-oriented sales a GT R Roadster in factory AMG Green Hell Magno or factory designo colour is generally priced higher than a regular GT R coupé.
The AMG GT R has seen a stable valuation curve since launch. In 2025 regular GT R coupés in factory specification sit consistently in a strong price range, with factory designo and AMG Green Hell Magno specifications in a higher tier. The GT R Pro and GT R Roadster are in a substantially higher class due to their limited production and unique factory specifications. For sellers this means a well-documented GT R with proven Mercedes-AMG service history, original specification, and (for Pro and Roadster) confirmed factory specification attracts strong international interest. The buyer you want is a Mercedes-AMG enthusiast who values the modern AMG track culture and knows the specific GT R specification.
AMG GT R coupé (2016-2021, 585 hp), AMG GT R Roadster (2019-2020, 585 hp, limited to 750 cars), or AMG GT R Pro (2018-2020, limited production with sharpened chassis, factory-installed coilover suspension, and more extensive factory carbon packs). For collectors the GT R Pro is generally the most valuable specification, followed by the Roadster due to limited production.
The GT R has factory-installed Active Aerodynamics with an extending rear wing that is electronically controlled for downforce or drag reduction. Additionally factory-installed front spoiler, factory-installed rear diffuser, and factory-installed lightweight wheels. For collectors, confirmation that all factory-installed aero elements are original is essential.
For GT R collectors, factory designo colours and the iconic factory AMG Green Hell Magno (matte green, a reference to the Nürburgring) strongly drive price. Other sought-after factory colours include designo Selenite Grey Magno, factory matte specifications, and factory-installed graphic stripe combinations. Factory carbon packs exterior and interior reinforce value.
GT R service is specialist work: the 4.0-litre M178 V8 biturbo, the seven-speed AMG SPEEDSHIFT DCT gearbox, and the factory-installed Active Aerodynamics require factory diagnostics. Service at a Mercedes-Benz dealer with AMG certification or Mercedes-AMG Performance Center is essential. Major service intervals depend on specification and use.
The GT R has factory-installed nine-stage traction control (adjustable via a dashboard knob, similar to Ferrari's manettino), AMG RIDE CONTROL adaptive dampers, and factory-installed AMG Coilover suspension (on the GT R Pro). For collectors, confirmation of factory chassis settings via factory documentation is essential.
For GT R collectors low mileage (under 15,000) in original condition is generally value-driving, although the GT R also has a natural home on the track. For track-oriented buyers documented trackday history with proven post-session service at Mercedes-AMG is attractive; both markets exist in parallel.
For GT R Pro and Roadster specifications, Mercedes-Benz Classic Center supplies factory documentation on request of the original specification, factory-installed packages, and build information. For collector-oriented sales this document reinforces confirmation of factory specification.
Note: These factors may influence buyer interest. Value depends on many factors.
AMG GT R coupé (2016-2021), AMG GT R Roadster (2019-2020, 750 cars worldwide), or AMG GT R Pro (2018-2020, limited production). Model year, chassis number, and engine number. For the Roadster: confirmation that the soft-top roof mechanism operates without faults. For GT R Pro: confirmation of factory-installed Coilover suspension and aero package.
Strongly recommended for GT R Pro and Roadster. Apply via a Mercedes-Benz dealer or Classic Center in Fellbach based on the chassis number. Confirms factory specification, colour, factory-installed Active Aerodynamics, factory designo options, and any AMG Performance Studio details.
All invoices from a Mercedes-Benz dealer with AMG certification or Mercedes-AMG Performance Center. The 4.0-litre M178 V8 biturbo and the seven-speed DCT gearbox require factory diagnostics. For GT R and GT R Pro: factory diagnostics of Active Aerodynamics and nine-stage traction control. Major service intervals depend on specification.
The factory-installed Active Aerodynamics (extending rear wing, electronically controlled front spoiler elements) is a defining GT R feature. Document factory diagnostic report confirming the system is fully functional. For collectors, proof of working Active Aerodynamics is essential.
Paint colour with factory code, designo confirmation if applicable, factory AMG Green Hell Magno (matte green, iconic GT R colour), factory carbon packs exterior and interior, AMG Performance Studio details, leather specification with factory embroidery. For collectors factory designo and Green Hell Magno are substantially higher priced.
The GT R Pro has factory-installed AMG Coilover suspension (manually adjustable), factory carbon canards on the front spoiler, factory-installed rear wing, weight saving, and more extensive factory carbon packs. Confirm all factory-installed Pro elements are original and not replaced with aftermarket components.
Number of previous owners, mileage, any trackday participation (date, location, number of sessions), post-session service at Mercedes-AMG, any damage history. For collector-oriented sales without track focus low mileage is value-driving; for track-oriented buyers documented trackday history is a selling point.
