Mercedes GLC 63 and GLC 63 Coupe revealed as Porsche Macan Turbo rivals
The new Mercedes GLC 63 4Matic+ and GLC 63 Coupe 4Matic models have been revealed
New pairing uses same engine as C 63 and come in 469bhp regular or 503bhp S guises; sales commence this June
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, running AMG’s widely used twin-turbocharged 4.0-litre V8 petrol engine that, in a move mirroring that of the C 63 4Matic and C 63 4Matic Estate, offers buyers the choice of either 469bhp in standard guise or a heady 503bhp in a pair of range topping ‘S’ models.
Confirmed for UK delivery in September, the GLC 63 4matic+ and GLC 63 4Matic+ Coupe are the latest models to receive AMG’s new Panamericana grille treatment first introduced on the GT R as part of a series of exterior styling elements that help to visually differentiate them from lesser GLC and GLC Coupe models, including AMG’s own GLC 43 and GLC 43 Coupe.
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 used by the recently introduced E63 4Matic+ and E63 4Matic+ Estate. Further changes include wider black plastic flares within the wheelarches, ‘V8 Turbo’ badges along the flanks, wider sills underneath the doors and a new rear bumper housing an integrated diffuser element and four trapezoidal shaped chromed exhaust pipes.
The changes inside correspond with those seen on the C 63 4Matic and C 63 4Matic Estate, with unique instrument graphics, a flat bottom steering wheel, AMG sport seats and various AMG specific controls within the centre console.
Power for the GLC 63 4Matic+ and GLC 63 4Matic+ hails from the same version of AMG’s twin-turbocharged 4.0-litre V8 petrol engine used in the C 63 4Matic and C 63 4Matic estate tuned to deliver 469bhp and 479lb ft of torque in standard guise. With added turbocharger boost pressure, it provides an additional 34bhp and 37lb ft of torque in a pair of headlining ‘S’ models, which boast 503bhp and 516lb ft.
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 kicks out a 355bhp and 343lb ft.
But while the C 63 4Matic and C 63 4Matic Estate run a seven-speed version of AMG’s Speedshift MCT gearbox, the new GLC 63 4Matic+ and GLC 63 4Matic+ Coupe come as standard with the newer nine-speed variant of the wet clutch equipped transmission, as launched on the E 63 4matic+ and E 63 4Matic+ Estate late last year.
The new AMG pairing also adopt the latest version of the Mercedes-Benz performance car division’s 4Matic four-wheel drive system. Also launched on the E 63 4Matic+ and E 63 4Matic+ Estate, the new set-up, which remains exclusive to AMG models for now, uses an electromechanically controlled clutch to connect the permanently driven rear axle with the front axle and provide a fully variable apportioning of drive dependent on prevailing grip and traction levels.
Following the lead of other recent new AMG models, the GLC 63 4Matic+ and GLC 63 4Matic+ Coupe also receive a so-called Dynamic Select system that provides standard models with the four different driving modes: Comfort, Eco, Sport and Sport Plus. The top-of-the-line “S” models also receive a fifth mode: Race. As well as providing variable properties for the throttle and gearbox mapping, the Dynamic Select system also provides the new AMG models with a coasting function on a trailing throttle at speeds between 37mph and 100mph in Eco mode.
AMG is yet to provide official acceleration figures for the various GLC 63 4matic+ and GLC 63 4Matic+ Coupe models, though insiders at its headquarters in Affalterbach on the outskirts of Stuttgart in Germany hint at a 0-62mph of around 4.0sec in “S” guise. By comparison, Porsche claims a 0-62mph time of 4.4sec for the Macan Turbo optioned with the new Performance Package, while the BMW X3 M40i boasts a claimed 0-62mph time of 4.9sec.
As with its rivals, Mercedes-AMG confirms a limited top speed of 155mph for its latest models.
Underpinning the GLC 63 4Matic+and GLC 63 4Matic+ Coupe is a suspension system that combines the four-link arrangement from the C 63 4Matic and C 63 4Matic Estate at the front with the multi-link set-up from the E 63 4Matic+ and E63 4Matic+ Estate at the rear – the latter featuring a wider track and greater negative camber than other GLC and GLC Coupe models. Also included is an AMG tuned version of Mercedes-Benz’s three-chamber Air Body Control system offering three levels of damping stiffness: Comfort, Sport and Sport Plus.
The GLC 63 4matic+ and GLC 63 4matic+ Coupe runs on standard 8.0-inch wide 19-inch front wheels and 9.0 inch wide 19-inch rear wheels shod with 235/55 front and 255/50 rear tyres. The more powerful GLC 63 4Matic+ S and GLC 63 4Matic+ S Coupe receive 9.5 inch wide 20-inch wheels up front and 10.0-inch wide 20-inch wheels at the rear shod with respective 265/45 and 295/40 profile tyres. Buyers can also specify the new AMG models with optional 21-inch wheels.
At market launch an Edition 1 model will be offered with a unique combination of equipment. This includes a night pack with black details on the car’s exterior, matt black 21in alloys and a spoiler. Inside there’s nappa leather, a performance steering wheel and carbonfibre trim.
Pricing for the new models is yet to be confirmed, but expect the GLC 63 to start at £64,00 and the GLC Coupé to start at £56,000 when sales start on 16 June.
