It's rare to see people expressing discontent from an AMG product, but just to be safe, German tuning house Carlsson have an ambitious project - The Carlsson CK63 RS. It is based on the current Mercedes-Benz CLS 63 AMG but with a bigger bite, lower ride and a dash of exclusivity. Carlsson do mean business, for a performance bundled version of the CK63 RS is set to appear to the public at the 2012 Geneva Motor Show.

The standard CLS 63 AMG with Performance package has a 5.5 V8 biturbo engine that feeds 557 BHP and 800 Nm of torque to the AMG Speedshift 7-speed sports gearbox. After Carlsson had finished working with it, that bar had been set even higher even higher, or so they claim - 652 BHP and one thousand Nm of torque. That is why, the Carlsson engineers also saw fit to instal an additional transmission oil cooling system. All this effort translates into a time of 4.1 seconds on the 60mph sprint. A very loud sprint if we may add. The exhaust system has been replaced by a tailor-made, multi-flow, complete stainless steel setup with downpipes, metal catalysts and front and rear silencers. Of course you can tone it down to become as silent as a gentle purr, thanks to the exhaust damper system controlled manually from the driving seat. But who would leave it like that?

Few would dare to modify the handling of a Performance package AMG but the newfound power calls for some tweaks – the front axle springs have been replaced with Carlsson springs with more progressive spring characteristics. Also as a consequence the ride is now 30 mm lower. The whole car sits on 1/10-type Carlsson wheels - 9 x 20" rims at the front and 10.5 x 20" at the back.

More personality is added when we look at the aerodynamic features of the Carlsson. A front spoiler and RS carbon spoiler lip decorate the nose while at the back we have a custom diffuser and a rear spoiler for greater downforce.

The interior of the CK63 RS can best be described as a blend of mocha-brown leather, brown Alcantara, carbon fiber, natural woods and more. The leather used is wet-dyed, providing the feeling of a fine leather glove and, because the finished product is 1/1.4 millimeters thick, it is also particularly durable. Other Carlsson highlights include the foot mats, door sill panels with blue, illuminated Carlsson lettering and door-locking pins made from polished aluminum. It's not all upholstery though. We do not excel much in IT, but the Carlsson have fitted a 'Viprinet Multichannel VPN Router 500'... which sounds fast. In fact it is. The company says that with this the RS will have a stable high-speed Internet connection even at high speeds.
