The 2025 Mercedes-AMG GT 63 Pro 4MATIC+ Coupe has been revealed: a high-performance, premium supercar designed to give track-focused coupes like the Porsche 911 GT3 RS a run for their money.
Revealed in full at the 2024 Goodwood Festival of Speed in the UK this week, the new GT 63 Pro is based on the second-generation Mercedes-AMG GT flagship coupe which is set to arrive here later this year. high-end form 63.
This is the effective replacement of the hard core Mercedes-AMG GT R Pro and is aimed at those who want a track-ready weapon that won’t buckle under pressure and can be driven on the race track.
To this end, it is equipped with the largest carbon-ceramic brakes ever seen as standard on an AMG model, numerous active aerodynamic systems and significantly improved cooling systems.
Almost certain to be available in limited numbers in Australia later in 2025, the AMG GT 63 Pro features an upgraded V8 that is claimed to propel the all-wheel-drive coupe to 100km/h in just 3.2 seconds.
Its 4.0-litre twin-turbo engine develops 450kW and 850Nm, an increase of 20kW/50Nm over the standard Mercedes-AMG GT 63 but less than the GT 63 SE Performance which packs a combined 600kW/1420Nm of power from its V8 plug-in hybrid powertrain, which is claimed to hit 100km/h in a hypercar-like 2.8 seconds, making it the fastest model ever.

While the original AMG GT has been out of production for over 18 months and unavailable in Australia for over a year, leaving Mercedes-Benz without a rival for the 911, the new AMG GT is also expected to spawn replacements for the old one.

For the new 63 Pro, which bills itself as the “sportiest” version of the new AMG GT yet, AMG engineers have beefed up the V8’s cooling system to ensure the drivetrain doesn’t cook under extreme stress, via a pair of larger radiators positioned behind the front bumper’s larger side air dams.
The variable all-wheel-drive system is now actively cooled via top-mounted radiators (with electrically controlled water pumps) on the front and rear differentials and transfer case.
The Affalterbach researchers also redesigned the front of the sports car to provide more cooling and improve downforce, via the AIRPANEL active air control panel which manages thermal and aerodynamic requirements by regulating the airflow.
Additional exposed carbon fibre air deflectors have also been added to the front and an ‘active aerodynamic profile’ has been applied to the underbody.
Combined with a fixed rear wing, these measures are said to add 15kg of rear downforce while reducing front downforce by 30kg to deliver “even more precise steering behaviour”.
AMG has also fitted the GT 63 Pro as standard with its advanced hydraulic suspension, which also features rear-wheel steering.
The massive 420mm carbon-ceramic front disc brakes clamped by large six-piston fixed calipers at the front (single piston at the rear) are now lighter thanks to their titanium mount.
Recalibrated underbody air vents are also said to improve brake cooling.
With a top speed of 317 km/h, the AMG GT 63 Pro needs premium tyres fitted to its lightweight 21-inch forged alloy wheels, with Michelin Pilot Sport 5 tyres fitted as standard and Michelin Pilot Sport Cup 2 R tyres available at no extra cost.
Speaking of cost, Mercedes-AMG hasn’t set a price for the new GT 63 Pro yet, but it won’t be cheap considering its predecessor was priced just above $450,000.
