A striking characteristic of the exterior design is the expressive front end: the new GLC 63 4MATIC+ is the first Mercedes-AMG Performance vehicle to feature the Panamericana grille, which was previously reserved for the AMG GT family of sports cars. This design statement affirms the consistently dynamic design of the new Performance SUV and Coupe. A wide front apron inspired by the design of a jet wing, with a large front splitter, impressively embodies the power of the new models. By dispensing with a fine-meshed grille, it gives a view of the cooling technology - a typical attribute from the world of motor sport and a further differentiation from the other GLC models. Wider wheel arch claddings at front and rear lend emphasis to the muscular looks. The new side sill panels make the SUV and Coupé appear to sit lower on the road while elongating the overall lines. On the S-model variant, matt iridium silver inserts make for a distinctive appearance. The muscular rear end is dominated by the wide rear apron and diffuser in grained black. The trim on the diffuser board of the S-model variant is in matt iridium silver. The SUV is for the first time provided with a spoiler lip on the roof, while the spoiler lip on the Coupé is familiar from the GLC 43 4MATIC. The exhaust system is terminated by two high-gloss chrome-plated twin tailpipe trims.
