2025 Mercedes-AMG GT 63 PRO 4MATIC+ Is Ready For The Track

Introducing the 2025 Mercedes-AMG GT 63 PRO 4MATIC+, the newest addition to the AMG GT lineup. Agile response to driver input and heightened overall performance provide an even sportier driving experience, especially on the racetrack.

While the Mercedes-AMG GT 63 is a beast in its own right, the engineers in Affalterbach have managed to squeeze even more power out of the handcrafted AMG 4.0L V8 biturbo, delivering a whopping 603 horsepower (an increase of 26 HP) and 627 lb-ft of torque (an increase of 37 lb-ft). This enables impressive overall performance, especially at higher speeds.

The Mercedes-AMG GT 63 PRO 4MATIC+ sprints from 0 to 124 mph in just 10.9 seconds (0.5 seconds faster than the AMG GT 63), with a top speed of 197 mph.

Aerodynamics and driving dynamics specialists collaborated closely on the aerodynamic fine tuning of the new AMG GT 63 PRO to increase overall performance in terms of longitudinal and lateral dynamics. The unique front fascia has an even more aggressive appearance with additional carbon fiber air deflectors around the enlarged side air intakes.

The active aerodynamic profile in the underbody, AIRPANEL active air control system in the front fascia and the AMG Aerodynamics Package with fixed rear wing are also fitted standard. Aerodynamic lift on the front axle is reduced by over 66 lbs. for even greater handling stability.

It also features additional air deflectors on the underbody – similar to those on the Mercedes-AMG ONE. These fins, which are located at the height of the front and rear axles, accelerate the airflow on the underbody. All aerodynamic measures are coordinated and interact with the fixed rear wing concept, which increases downforce on the rear axle by approximately 33 lbs.

Given that this car was built for the racetrack, AMG GT engineers reinforced both high and low temperature cooling circuits to ensure optimal drivetrain temperatures. Two radiators are now positioned in the left and right front wheel arches to increase cooling efficiency and ultimately enhance overall vehicle performance on the racetrack.

The top-mounted radiators for the front and rear differentials, along with the transfer case of the AMG Performance 4MATIC+ fully variable all-wheel drive are now actively cooled. Electrically operated water pumps ensure circulation of coolant in the corresponding circuits and can therefore better and more continuously dissipate heat via the top-mounted radiators.

Additionally, the new geometry of the air vanes on the underbody and revised brake cover plates optimize airflow to the brakes which increases durability and prevents excessive brake temperatures.

On the braking front, an AMG carbon ceramic high performance composite brake system is standard. It features six-piston fixed calipers at the front paired with 16.5-inch brake discs – the largest standard ceramic brake discs currently available from Mercedes-AMG – and single-piston floating calipers at the rear. The backs of the carbon ceramic discs are made of high-strength, lightweight titanium, which contributes to the brake system’s reduced unsprung mass. The system provides high stability and fade-resistance – even under extreme load.

Lightweight AMG Performance 21-inch Forged Split Spoke Wheels finished exclusively in Himalaya Grey Matte are fitted standard with Michelin Pilot Sport 5 tires (295/30 ZR 21 at the front and 305/30 ZR 21 at the rear). Michelin Pilot Sport Cup 2 R extreme performance tires are also available at no additional cost.

Visually, the standard AMG Exterior Carbon Fiber Package emphasizes the highly dynamic character of the AMG GT 63 PRO with a front splitter, side sill trims, rear diffuser and rear wing made from high-quality carbon fiber. Black-painted brake calipers, AMG Performance seats with a high level of lateral support and an AMG Performance steering wheel in Nappa leather/microfiber are also included standard.

From the looks of it, this should be one heck of a car both on and off the track, with increased power, aerodynamic fine tuning and enhanced cooling all contributing to coupe’s exceptional driving dynamics and faster lap times.

Pricing for the 2025 AMG GT 63 PRO 4MATIC+ hasn’t been released yet, but given the AMG GT 63’s $177,050 starting price, somewhere in the $190,000-$200,000 range wouldn’t surprise me. We should know more closer to 2025, when the cars are slated to arrive at dealerships.
