2024 Mercedes-AMG GLC 63 S E Performance Coupe Photos, engines & full specs

Mercedes-AMG introduced the most powerful version of the GLC Coupé’s second generation in 2023, but unlike its predecessor, it featured an inline-four under the hood.

Mercedes-Benz launched the second generation of its compact-sized crossover GLC in the Fall of 2022 and, just a few months later, in March 2023, brought its Coupé version. But customers waited for the most powerful versions of it who wore the AMG badges. They didn’t have to wait too much because just a few weeks after the unveiling of the sloped-back version of the GLC, Mercedes-AMG launched not one, but two versions for it: the GLC43 and the GLC63. The latter was also the most potent and shared its underpinnings with the C63 AMG.

These two new models were almost identical from the outside. Like its GLC43 sibling, the GLC63 sported a Panamericana grille adorned by vertical slats. It was flanked by AMG-specific LED headlights, which sported eyebrow-style daytime running lights. On the lower bumper, the automaker placed a wide A-shaped grille flanked by big side scoops. From its profile, the wheel arches sported body-colored trims covering the standard 19” light-alloy wheels. The automaker also offered customers the option for 20” and 21” sets. Unlike the regular GLC Coupé, the AMG-enhanced version sported aerodynamically-profiled side skirts. At the back, the compact-sized GLC63 Coupé featured an underbody diffuser flanked by trapezoidal exhausts.

Inside, the automaker put effort into creating a luxurious, yet sporty, cabin. For instance, the sport bucket seats with high-bolstered areas were covered in ARTICO man-made leather upholstery in combination with Microcut AMG microfiber. As an option, the car manufacturer installed Nappa upholstery and AMG performance seats with tall seatbacks and integrated headrests. Fronting the driver was a digital display with an AMG-specific design and a flat-bottom, three-spoke steering wheel wrapped in Nappa/Microfiber. Moreover, the GLC63 S was also fitted with aluminum paddle shifters behind the steering wheel for situations when the driver wanted to manually change gears. The portrait-mode screen for the MBUX infotainment unit found its place in front of the center stack. Unlike the rest of the GLC range, this one featured additional menus and a “Supersport” style, allowing customers to display various contents vertically. Between the front occupants, the automaker placed a tall center console finished with piano-black trims and housing a storage compartment under the armrest. On the rear flat-folding (60/40) bench seat was room enough for three adults, although with limited headroom for outboard passengers.

Mercedes-AMG ditched the formerly used 4.0-liter V8 and installed a turbocharged four-pot engine helped by an electric motor and a belt-driven starter generator (RSG). As a result, it provided 680 PS (671 HP), which was 170 PS (168 HP) more than its predecessor. The new unit sent its power in all corners via an AMG SPEEDSHIFT MCT (multi clutch technology) 9G gearbox and variable torque distribution between the front and rear axle.
