The AMG GT 63 Pro gets noticeable aero upgrades over the standard AMG GT 63.

Starting with the engine, the 4.0-litre twin-turbo V8 has been fettled to extract an additional 27 bhp and 50 Nm over the standard GT 63 to 603 bhp and 850 Nm. Mercedes says that this has helped shave off 0.5 seconds from the 0-200 kmph sprint time of the sportscar. The GT 63 Pro hits the mark in 10.9 seconds. Top speed stands at 317 kmph.

The increased performance is accompanied by an upgraded powertrain cooling system with additional radiators positioned ahead of the front wheel arches. The front and rear differentials and the 4Matic all-wheel drive system case now also get active liquid cooling for faster dissipation of heat while revised underbody channels and brake covers direct more air to the brakes for improved cooling.

Twin-turbo V8 now produces 603 bhp and 850 Nm; reduces sprint time to 200 kmph by 0.5 seconds.

Sticking with the brakes, the GT 63 Pro gets ceramic composite brakes as standard with six piston callipers up front and one-piston callipers at the rear. Mercedes says that at 420 mm, the front brake discs are the largest yet to be fitted to a Mercedes-AMG road car. In a bid to shave weight the GT 63 Pro incorporates titanium into the rear of the brakes and sits on 21-inch forged wheels. Michelin Pilot Sport 5 tyres are offered as standard though buyers can opt for stickier Michelin Pilot Sport Cup 2Rs as a no-cost option.

The AMG GT 63 Pro gets a redesigned front apron with active vents and a fixed rear spoiler as standard; ceramic composite brakes are also standard.

Moving to the aero upgrades, the GT 63 Pro gets a redesigned front apron with additional air deflectors designed to channel air into the larger side air vents on the bumper. AMG’s AirPanel active air control system is packaged in a part of the standard equipment list as is the fixed rear wing. The GT 63 Pro also gets additional air deflectors in the underbody to better channelise the airflow. Mercedes says these tweaks have helped reduce aerodynamic lift over the front axle by as much as 30 kg and increase rear-end downforce by up to 15 kg. Additionally, bits such as rear-axle steering, active ride control and active roll stabilisation are part of the standard kit.
