This is the 2023 Mercedes-AMG GT 63 and GT 63 S 4-Door Coupe and while you may have to squint to notice any changes, upgrades have indeed been made. The revised GT 4 lineup will launch in the U.S. later this year. In tweaking the exterior design of the GT 63 and GT 63 S, Mercedes-AMG’s designers borrowed the front fascia from the existing GT 63 S E Performance flagship. As such, the outer air intakes are slightly wider than before and each incorporates three vertical fins as opposed to the horizontal fins of pre-facelift models.

Mercedes has also made the updated GT 63 and GT 63 S 4-Door models more customizable than ever before. For example, the range of Manufaktur colors has grown and now includes Arabian Grey, Cashmere White Magno, and China Blue. All up, buyers can now choose between four matte paints, five metallic shades, and two solid colors, including new shades of Starling Blue Metallic and Starling Blue Magno first featured on the facelifted six-cylinder GT 4-Door from last year. Also offered is the new AMG Night Package II and a combination of the Night Package and AMG Exterior Carbon Fiber Package.

 

The German car manufacturer has also extended the Manufaktur range of interior options with new Nappa leather and diamond quilting. There is also a two-tone AMG Performance steering wheel and AMG high-pile floor mats with embroidered AMG lettering. Mercedes is promising to launch further individualization options in the coming years.

Upgrades have also been made to the standard AMG Ride Control+ suspension system. The setup is based on Mercedes-Benz’s Air Body Control suspension and features electronically controlled adaptive and adjustable dampers. This new system features two pressure limiting valves that allow the damping force to be adjusted even more precisely depending on the drive mode and driving conditions. The result is improved comfort and even sharper driving dynamics.

 

The system also features a suspension control unit that analyzes data, including information from acceleration and wheel path sensors, to automatically adjust the damping force for each wheel in just a matter of milliseconds. The various settings of the suspension can be tweaked through the driving modes or independently via a dedicated damping button.

No changes have been made to the engines of the duo. As such, both feature a 4.0-liter twin-turbocharged V8 that in the GT 63, delivers 575 hp between 5,500 and 6,500 rpm and 800 Nm from 2,350 to 5,000 rpm. The GT 63 S has a touch more grunt and is rated at 630 hp from 5,500 to 6,500 rpm and 900 Nm from 2,500 to 4,500 rpm.
