2026 Mercedes-AMG GT 63 PRO 4MATIC+

Mercedes-AMG revived its most focused badge for the GT 63, but this PRO earns its name by a much smaller margin than the last one

The PRO badge has serious history at Mercedes-AMG. The previous generation GT R PRO was a proper track weapon, limited to 750 units, with manually adjustable motorsport derived coilovers, revised aerodynamics and a diet that shed 25 kg through carbon bucket seats. It carried no extra power over the regular GT R, yet it lapped the Nürburgring seven seconds faster. Now the badge returns on the new AMG GT 63 PRO 4MATIC+, and this time there is no limited run: anyone can order one, which suits a car meant to see regular track days. We spent time with it to see whether the PRO magic survived the transition.

The V8: still the heart of the car

Start with what matters most, the V8. It remains a classic AMG unit in every sense, with torque to spare and a loud, deep grunt that defines the whole experience. Mercedes has raised output to 612 hp (450 kW) and 850 Nm, an increase of 27 hp and 50 Nm over the standard GT 63, achieved purely through revised engine mapping. The synthesised sound piped through the speakers can feel a touch intrusive at times, but there is still plenty of genuine mechanical noise coming from the car itself.

Performance: brutally quick, even by AMG standards

The extra power shows most at higher speeds. Mercedes-AMG quotes 3.2 seconds to 100 km/h, 10.9 seconds to 200 km/h, half a second quicker than the regular GT 63, and a top speed of 317 km/h. On the road it feels every bit as violent as those numbers suggest, and there are few cars that will trouble it in a straight line.

Cooling and aerodynamics: proper motorsport thinking

Mercedes-AMG has clearly done its homework under the skin. Two additional radiators now sit in the front wheel arches, the differentials and the transfer case gain active cooling through electrically driven water pumps, and revised underbody air guide vanes route more air to the brakes. Aerodynamically, a redesigned front apron with carbon fibre air deflectors cuts front axle lift by more than 30 kg, while a fixed rear wing and underbody fins similar to those on the AMG ONE add around 15 kg of rear downforce. These are the kind of details that matter when a car is actually driven hard on a circuit rather than just photographed on one.

Suspension: the one place PRO does not feel special

What disappointed us slightly is that the suspension itself carries over largely unchanged. It remains very good, but we could barely detect a difference between comfort and sport plus, whereas the previous GT R PRO had genuine motorsport derived adjustable coilovers with sharpened suspension kinematics. On this car the PRO name promises more than the chassis hardware actually delivers.

Price and positioning: hard to justify next to the standard car

The AMG GT 63 PRO is a proper AMG, with heaps of torque and a powerful V8 grunt, and it is faster than almost anything else on the road. In Belgium it lists from €227,480, against €186,945 for the standard GT 63 4MATIC+, a gap of more than €40,000. That is a serious premium for a car whose suspension barely feels different from the one it is based on, and it makes the point of the PRO badge even harder to see this time around.

AutoNext Verdict

The AMG GT 63 PRO is a genuinely fast, characterful car, with a V8 that still defines the whole experience and cooling and aerodynamic upgrades that show real motorsport thinking underneath the skin.

It is not the leap the PRO badge implies, though. The suspension barely feels different from the standard car, and the improvements over the regular GT 63 are modest for what the PRO name has previously stood for, especially set against a price that is over €40,000 higher in Belgium.

If money were our own, we would rather have a regular GT 63 and leave the PRO badge to the previous generation, where it earned its keep in a way this one only partly manages.
