The new Mercedes GLC 63 4Matic+ and GLC 63 Coupé 4Matic models have proved to be, in view of a public debut next week at the New York motor show.
Fed-up of mid-size SUV twins attend AMG 48 existing models and is also aimed directly 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 that mirrors that of the C 63 4Matic and C 63 4Matic Summer, offers buyers the choice of 469bhp in standard guise or a heady 503bhp in a few of the range topping ‘S’ models.
Confirmed for delivery in the UNITED kingdom in the month of September, the GLC 63 4matic+ and GLC 63 4Matic+ Coupe are the latest models to receive AMG’s new pan-american highway grid treatment for the first time on the GT-R as part of a series of external style elements that help visually differentiate them from less GLC and GLC Coupe models, including AMG’s own GLC 43 and GLC 43 Coupe.
The characteristic front grille, housing with vertical slats and Mercedes-Benz’s signature three-pointed start, it is embedded in a unique way and the style of the front bumper similar to that recently introduced the E63 4Matic+ and E63 4Matic+ Summer. Other changes include wider black plastic flares within the wheelarches, ‘V8 Turbo’ badges along the flanks, the wider the thresholds under the doors and a new rear bumper housing integrated diffuser element and four trapezoidal chromed exhaust pipes.
The changes inside match those seen on the C 63 4Matic and C 63 4Matic Summer, with a unique instrument graphics, a flat bottom steering wheel, AMG sports seats, and various AMG-specific controls inside the center console.
The power for the GLC 63 4Matic+ and GLC 63 4Matic+ greets with 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 that delivers 469bhp and 479lb ft of torque in standard guise. With the addition of turbocharger boost pressure, provides an extra 34bhp and 37lb ft of torque in a couple of headlining the ‘S’ models, which boast 503bhp and 516lb ft.

In comparison, the Porsche claims a 0-62-mph time of 4.4 sec for the Macan Turbo equipped with the new Performance Package, while the BMW X3 M40i has a claimed 0-62mph time of 4.9 sec.
