The Mercedes-AMG GLC 63 Coupe was only unveiled last year, so it might not seem like a model that urgently needs an update. Despite this, our spies have spotted a prototype of an updated version being tested at the Nurburgring, suggesting that the AMG GLC 63 Coupe will be getting a facelift sooner than expected. It makes sense, however, since the regular GLC and GLC Coupe are getting mid-cycle updates next year, so Mercedes will want all models to have consistent styling.

Like the upcoming updated GLC, don't expect any major styling changes as Mercedes doesn't want to alienate fans of the current design. Compared to the outgoing model, the updated AMG GLC 63 features new headlights and taillights with a slimmer design. The prototype's front bumper is heavily camouflaged, it could be getting a redesign to distinguish the GLC 63 Coupe from the GLC 63. Elsewhere, the Panamericana front grille has also been partially covered, but it remains to be seen if it will be tweaked. The rear diffuser also appears to be larger than its predecessor's.

Since the current model hasn't been on sale for very long, the 2020 Mercedes-AMG GLC 63 Coupe probably won't get any powertrain upgrades. Expect it to launch with a 4.0-liter twin-turbocharged V8 that produces 469 hp and 479 lb-ft of torque in the standard model and 503 hp and 516 lb-ft in the S guise.
