There are two versions of the GLC 63 Coupe available. Both are equipped with a 4.0-liter twin-turbo V8 engine, sending the power to a 4MATIC all-wheel-drive system via a nine-speed Speedshift automatic gearbox. The standard 63 produces 469 hp and 479 lb-ft of torque, whereas the S unleashes 503 hp and 516 lb-ft.
On the outside, both models have LED headlamps, taillamps, and daylight running lights. Both have 20-inch alloys and quad exhaust pipes. The S model comes with a diffuser fin and strips finished in Iridium Silver. On the inside, the standard 63 has MB-Tex and Dinamica upholstery, while the S has full leather. Mercedes’ MBUX infotainment system is standard and comprises a 12.3-inch digital instrument cluster and a 10.25-inch touchscreen. Other standard comforts include front power seats with heating, dual-zone climate control, and a 13-speaker Burmester sound system. A surround-view camera has been included as standard for 2021.
Both models come with seven airbags and Pre-Safe accident detection, but active cruise control and lane-keep assist remain optional extras.
