At the Frankfurt motor show, German tuner Carlsson premiered the Carlsson CK63 RS - based on the Mercedes-Benz CLS 63 AMG with Performance Package.
To knock the 0 to 100 km/h sprint time of Performance Package CLS 63 AMG from 4.3 seconds down to 4.1 seconds, Carlsson adds some output to the series 557 PS (410 kW / 550 bhp) to take maximum horsepower and torque up to 649 PS (477 kW / 642 bhp) and 800 Nm (590 lb-ft).
Carlsson fits a carbon fiber aerodynamic kit too, which includes a new front spoiler and RS front spoiler lip, black-colored stainless steel grille inserts, rear boot-lid spoiler, rear skirt insert and RS rear diffuser.
A stainless-steel sport exhaust system with four oval pipes is also added, along with rim offerings up to 20-inch in size and an adjustable suspension kit which can lower the ride-height up to 30 mm for the CLS models equipped with the Airmatic suspension.
For the interior, Carlsson adopts Nappa leather in Mokka brown color along with carbon inlays in dark brown/matte. Other features include the illuminated door sill panels, soft velour floor mats with the Carlsson logo and door pins of brushed aluminium.
