Mercedes-AMG GT63 Pro Revealed

A slight increase in power is what’s new, alongside changes to make the range-topping GT sharper on track.

The original AMG GT Coupe was honed and sharpened with a series of faster and harder-hitting variants over the years—evolving steadily through the GT S, GT R, and ultimately the almighty GT Black series. Now the second-generation car that was launched last year is beginning the same journey. AMG has already released details about the forthcoming 805 – hp plug in hybrid GT63 S E. that will sit at the top of the range in terms of both price and performance. Now here’s another new version, the turned-up and track-focused AMG GT Pro which has been unveiled at the Goodwood Festival of Speed in the U.K.

In the new GT63 Pro 4Matic, the second-generation AMG GT’s 4.0-liter V-8 makes peaks of 603 horsepower and 627 pound-feet of torque.
Enhanced cooling and aerodynamics are the main changes to the car, which also gets standard carbon-ceramic brakes and optional track-biased Cup R tires.
Deliveries of this 2025 model are expected to start early next year.

Individual changes over the existing GT63 are small, but the cumulative result is claimed to be a significant improvement in performance when the car is driven on a circuit. The Pro’s power output has been increased, cooling improved, and carbon-ceramic brakes added as standard. Track-biased tires will also be offered at no extra cost. According to AMG boss Michael Schiebe, the Pro is well suited to track use but without becoming harsh on-road, “to maintain a high level of day-to-day usability for a car of this type.”

The adaptability of AMG’s long-serving twin-turbo 4.0-liter V-8 means it has already been offered in outputs ranging from 450 to 750 horsepower and in both cross-plane and flat-plane-crank derivatives. The new GT63 Pro uses the regular cross-plane variant, which has only been modestly boosted when compared to the existing GT63, now making peaks of 603 horsepower and 627 pound-feet, increases of 26 hp and 37 pound-feet respectively. As with the GT63 it has 4Matic+ all-wheel drive and a nine-speed automatic gearbox that uses a wet clutch in place of a torque converter. Looking at AMG’s own numbers, the 3.1-second acceleration to 60 mph is unchanged from the regular GT63, but the Pro is claimed to be 0.5 second faster from zero to 124 mph, dispatching the tougher benchmark in just 10.9 seconds.

Substantial cooling improvements, though, have more relevance to the AMG’s intended racetrack habitat than the modestly raised output. The Pro gets enhanced cooling capabilities for the engine, plus additional water cooling circuits for the front and rear differentials as well as the electronically controlled transfer case, which apportions torque to each axle. Externally, there are also larger side intakes in the front bumper to help channel air to the brakes.

Although it will sit at the top of the range, the GT63 Pro is not going to be a limited-edition model, allowing the market to decide on its popularity relative to the other members of the clan.

We will get more details, including pricing, ahead of deliveries beginning early next year.
