The new Mercedes-AMG GLC 63 is on sale now, priced from £68,920, while its GLC 63 Coupé sister costs from £71,410, with a £6750 premium for the even hotter S models.
UK delivieries are set to commence in September.
Topping out the AMG GLC range is the Edition 1 spec, which, at £90,824 and £93,219 for the SUV and SUV-coupé respectively, adds matte grey paint, ceramic brakes - usually a £4285 option - a performance exhaust and 21in wheels, as well as upgraded interior features including a Burmeister sound system and contrastingly stitched seats. Features that are usually options, such as keyless go, are also standard.
S models get 20in alloys, upgraded AMG performance seats, an AMG track app and an electronic rear-axle differential lock. A £2755 (£765 for the GLC 63 S models) AMG Driver's package raises the top speed of the GLC AMG and GLC AMG S models to 167 and 174mph respectively.
The powered-up mid-sized SUV twins join AMG’s 48 existing models and take direct aim at the Porsche Macan Turbo and BMW X4 M40i. They're powered by AMG’s twin-turbocharged 4.0-litre V8 petrol engine that produces 469bhp and 479lb ft in standard guise or 503bhp and 516lb ft in S models.
Based on sales of the C63, GLC 63 AMG sales are expected to be split into mostly non-S cars for the standard SUV, while the coupe is expected to be nearer a 50/50 split, according to Mercedes. The most expensive option ticked from the list is expected to be the sports exhaust, as per the C-Class.
The GLC 63 and GLC 63 Coupé are the latest models to receive AMG’s new Panamericana grille treatment, as part of a series of exterior styling elements that help to visually differentiate them from lesser GLC and GLC Coupe models, including the AMG GLC 43 and GLC 43 Coupé.
The distinctive grille, housing vertical slats and Mercedes-Benz’s signature three-pointed start, is incorporated in a uniquely styled front bumper closely resembling that of the recently introduced E63. Further changes include wider black plastic flares within the wheelarches, wider sills underneath the doors and a new rear bumper housing an integrated diffuser element and four trapezoidal chromed exhaust pipes.
Interior changes correspond with those in the C63, with unique instrument graphics, a flat bottom steering wheel, AMG sports seats and various AMG specific controls within the centre console.
By comparison, the twin-turbocharged 3.6-litre V6 petrol engine used by the Porsche Macan Turbo develops 434bhp and 516lb ft when fitted with an optional Performance Package, while the turbocharged 3.0-litre in-line six-cylinder petrol engine of the BMW X3 M40i produces 355bhp and 343lb ft.
