Despite the second-generation AMG GT’s evolution into a more practical, four-seat sports car more focused on grand touring stuff, Mercedes-AMG is reassuring buyers of its commitment to track performance with the 2025 GT63 Pro. There was a GT R Pro version of the first-gen car, and while this new model isn’t quite as extreme — because surely there will be a new GT R eventually — the GT63 Pro gets some serious performance kit.

Introducing The Mercedes AMG E-Scooter

It’s powered by AMG’s familiar twin-turbo 4.0-liter V8 engine, which has 26 more horsepower and 37 more pound-feet of torque than the standard GT63 for totals of 603 hp and 627 lb-ft. Peak torque comes in 150 rpm sooner, too. Mercedes says the Pro will hit 60 mph from a standstill in 3.1 seconds, the same as the base car, but it reaches 124 mph half a second quicker (10.9 seconds) and it has a 1-mph-faster top speed (197 mph). If you need more speed than that, you’ll have to get the plug-in-hybrid GT63 S E Performance, which has 805 hp and will hit 60 in just 2.7 seconds.

AMG fitted the Pro with two radiators mounted in the front wheel arches, which increase the cooling efficiency, and the high and low temperature cooling circuits are reinforced. The top-mounted radiators for both the front and rear differentials as well as the all-wheel-drive system’s transfer case are now actively cooled with electrically operated water pumps. Standard are carbon-ceramic brakes with six-piston calipers and 16.5-inch discs at the front, the latter of which are the largest AMG offers, and high-strength titanium is used on the back of the discs to reduce unsprung mass. Staggered-width 21-inch wheels wear Michelin Pilot Sport 5 tires as standard, but Pilot Sport Cup 2 Rs are a no-cost option.

The Pro visually sets itself apart from the normal GT63 with a unique front end treatment that has larger side intakes with aerodynamic surrounds and a redesigned grille. Mercedes says aerodynamic lift on the front axle is reduced by more than 66 pounds, thanks to features like new underbody air deflectors and active air panels in the intakes. The Pro also comes standard with a fixed rear wing, an option on other GTs, which increases downforce by 33 pounds. Tons of exposed carbon-fiber trim is also included, of course.

Mercedes hasn’t announced how much the GT63 Pro will cost when it reaches U.S. dealers in 2025, but if I had to guess I’d wager it’ll start somewhere near $200,000, about $20K more than the GT63. I’m headed to Germany next week to drive the GT63 PHEV and ride on track in the GT63 Pro, so let me know what questions you have in the comments below.
