During the 2011 Geneva Motor Show, Carlsson unveiled the first upgrade package for the 2012 Mercedes CLS63 AMG, but it seems they opted out of taking a vacation over the summer to present us with something new. For the 2011 Frankfurt Show, the tuner has revealed the CK63 RS; a new package with even more impressive exterior modifications and an extra 50 HP over the previous package.
The new CK63 RS starts off with the new CLS63 AMG equipped with the AMG Performance Package which increases the V8’s engine output to 557 HP and 589 lbs-ft (up from 525 HP and 516 lbs-ft of torque). After a few tuning tweaks, the new CK63 RS delivers a total of 649 HP and 663 lbs-ft of torque, sprinting the Mercedes from 0 to 60 mph in 4.1 seconds.
The exterior design for the new generation Mercedes CLS isn’t ho-hum by any means, but the added muscle provided by Carlsson warranted some changes. For that the tuner added a new front spoiler, a carbon fiber front spoiler lip, painted stainless steel grille inserts, a discrete trunk lip spoiler, and a new rear bumper. There is also a new set of 20" wheels in a double spoke design (available in Brilliant Edition, Graphite Edition, and Titanium Edition) and a new stainless steel sport exhaust system with 4 oval end pipes.
The Mercedes can also be lowered by about 30mm with a Carlsson patented suspension with two sport springs. This suspension reads the road conditions every 150 milliseconds and adjusts accordingly.
For the interior, customers can choose between wood, leather, Alcantara, and carbon fiber. The vehicle’s door panels, seats, and the rear seat bench are covered in Mokka brown Carlsson nappa leather and the dashboard, door panels, and center console have dark brown/matte carbon inlays. Other features of the interior include illuminated door sill panels, soft velour floor mats with a Carlsson logo, and brushed aluminum door pins.
