What is the GLC Coupe?
The GLC Coupe is essentially a more stylish but less practical clone of the GLC SUV. However, the GLC Coupe isn't really a coupe — for that it would have to have just two doors. Instead, Mercedes has taken the meaning of the French word "coupé," which means "to cut," quite literally. The brand chops a bit of bodywork out of the rear (it also does this with the GLE) and sells the result as an alternative to the boxier, more usefully shaped GLC.
While 2024 saw the introduction of the redesigned GLC 300 and sportier AMG GLC 43, 2025 will add the big one: the AMG GLC 63 S E Performance. The name might be a mouthful, but it comes with a ton of added go-faster kit that earns it the higher numerical designation. The GLC 63 adds more power along with a far more aggressive look up front and at the rear. Throw in sticky tires, bigger brakes to haul you down, and trick handling tech like a limited-slip differential, and the 63 clearly has the chops to be top of the GLC food chain.
In case you're wondering where "63" even comes from, it used to refer to the displacement of the V8 engines found in the AMGs of old (6.3 liters). As time has gone on, downsizing has taken hold, and now some of AMG's 63 performance models have 2.0-liter turbocharged four-cylinder engines augmented by a battery and electric motor combo.
