At the 2013 Geneva Motor Show, Carlsson will unveil a very cool tuning kit based on the Mercedes CLS3 AMG. Named "CK63 RSR," this tuning kit takes the standard 518 horsepower V8 engine and tricks it to deliver an impressive 700 horsepower. Along with the extra power, the car also receives some pretty impressive exterior and interior upgrades that transform it into an even more amazing four-door coupe .
To deliver the extra power, the CK63 RSR received a more efficient intercooler system, additional water and oil coolers, plus an additional, thermostatically controlled oil cooler for the transmission. There is also a new high performance stainless-steel sports exhaust with 200-cell metal catalytic converters. The result is a tarmac-shredding output of 700 horsepower and 737 pound-feet of torque. With the extra power, the CK63 RSR will go from 0 to 60 mph in just 3.9 seconds, will pass the 124 mph barrier in 11.6 seconds and won’t stop until it will hits a top speed of 211 mph.
The aerodynamic package includes a new carbon-fiber front lip spoiler, black stainless-steel mesh inserts in the intake grilles, brake-cooling intakes and rear carbon valance insert. Carlsson also installed an electronically retractable rear spoiler, which extends into the airflow automatically at 62 mph to help improve downforce. For the interior, Carlsson combines the finest leather with Alcantara, carbon-fiber and natural wood.
Also, in order to handle the extra power, the CK63 RSR also receives height-adjustable coil-overs with 10-position bounce and rebound adjustment, and set of wheels sized 19 or 20 inches, depending on customer’s choice.
