Affalterbach is no more a purveyor of limited-build performance cars. With up to 35 models wearing the Mercedes-AMG badge for the current year, the performance wing of the Stuttgart carmaker now has more cars in its portfolio than many mainstream automakers do. With the addition of AMG 43 and AMG 45 designations to the mix, this list is poised to grow even longer. However, to enthusiasts, the ‘real’ AMGs are still those with 63 or 65 designations. And Mercedes has added one more model to that list with the announcement of the new GLC 63.

Set to make its official debut at the upcoming New York Motor Show, the mid-size SUV will be available in three variants; the GLC 63, the GLC 63 Coupe and the GLC 63 S Coupe. All three models are powered by a 4.0-litre biturbo V8, which makes 469bhp and 649Nm in the first two and 503bhp and 700Nm in the most powerful S variant. In all three applications, the V8 is mated to a nine-speed automatic transmission that sends power to an all-wheel-drive system. All three models come equipped with limited-slip rear differentials, with the ‘regular’ duo getting mechanical units, and the S benefitting from an electronically controlled unit.

New three-chamber air suspension and adaptive dampers will be standard in all three variants, and can be adjusted by the driver by selecting from the different drive modes available. These modes will also alter the shift patterns of the transmission.

In the looks department, the GLC 63 models get the same vertically oriented Panamericana grille seen in the AMG GT R. An aggressive diffuser, wide wheel arch cladding and quad exhausts round out the cosmetic changes. We’ll bring you our first-look impressions once we get up close with it at the New York show.
