When our man Jonathon Ramsey sampled the Mercedes-Benz SL63 AMG last year, he found it to be "just right." So we have to cringe a little when a tuning company getting their hands on one. Why alter a car that needs nothing? To Carlsson's credit, it's hard to argue against more horsepower (600), more torque (520 lb-ft), a higher top speed (202 mph), and larger carbon composite brakes. Other modifications, like the new grill with the prancing Carlsson horse and the butterfly doors are more likely to draw criticism. The same goes for the paint, which Carlsson calls Stealth Titanium Graphite and claims is the "most matte" color ever produced. If all of that sounds like your cup of tea, Carlsson is offering complete cars for a mere 272,500 Euros, or about $355,000 for us Statesiders. More details are available in the press release after the jump.

PRESS RELEASE:

With its CK63 RS refinement, Carlsson brings significantly more pressure on the streets than the Mercedes Benz SL 63 AMG which provides the basis for the new vehicle. More performance, a complete aerodynamics kit, finest leather in the interior and an exclusive varnish are the hallmarks of the new roadster from the Merzig-based company.

Carlsson, the automobile manufacturer specialised on Mercedes Benz models, invigorates the eight-cylinder with significantly more performance. Although the cubic capacity with 6,208 cc has not been changed, the refined power engine renders up to 600 hp (441 kW) instead of the serial 525 hp (386 kW) with the AMG.
Also the maximum torque rises from 630 Newton metres at 5,200 rpm to 705 at 5,100 rpm. With the Carlsson refinement, the sprint from zero to a hundred only takes 4.1 seconds and is therefore half a second faster than the AMG-model. The acceleration is electronically limited at respectable 325 km/h instead of 250 km/h.

In order to convey the power of the engine to the road, an extensive aerodynamic kit presses the CK63 RS onto the tar and provides an optimal grip. The air which is aspirated at the car front flows out through specially formed outlets at the car wings. Front apron and rear diffuser are made of polyurethane (PU) and are refined with carbon fibre elements which direct the air-flows for the best possible road grip.

C-Tronic® SUSPENSION – intelligent lowering

Moreover, the best road holding is guaranteed by the electronic lowering kit C-Tronic® SUSPENSION by Carlsson combined with the ABC-sports running gear by AMG. This enables to lower the roadster up to 30 millimetres. The high-performance brake system Carlsson Carbon Composite takes over the negative acceleration. At the front axle, 6-piston callipers carve into the 398x36 millimetre carbon composite brake discs. At the rear axle, two 4-piston callipers grab the 330x35 millimetre brake discs and stop the forged Carlsson 1/16 Ultra Light wheels sized 9.5x20 inches at the front and 11x20 inches at the back within the shortest time. As far as the last centimetres to the road are concerned, Carlsson chose the high- performance Dunlop SP SportMaxx with 255/30 ZR20 at the front- and 305/25 ZR20 at the rear axle.

Even when the CK63 RS is parked, it impresses with its breathtaking varnish called "Stealth Titanium Graphite", the far-most matt black colour that was ever produced. The co-operation between the internationally successful Mercedes-Benz refiner Carlsson and the expert for varnishes, Standox from Wuppertal, has led to a striking result. "Matt black was not enough for us" says Stafan Müller, responsible for Marketing at Carlsson. "We wanted a black varnish with such an extensive matt degree as it has never been seen before". This intention was more than successful with the CK63 RS. Normally matt varnishes reach a degree of 20 to 25 gloss units, but the particular colour which has been especially developed for Carlsson, only has five gloss units. "And the colour shade still remains brilliant and is neither blurred nor milky" ensures Sascha Pfeffer, application technology manager at Standox.

Apart from alterations for the varnish, engine and running gear, Carlsson also equipped the CK63 RS with a new interior. The seat sides, the inner lining of the doors and the cockpit hood scoop are made of charcoal-coloured ultra suede. The light ornamental seam renders an elegant contrast on these component parts. The soft velour car mats and the headrests are adorned with the prancing Carlsson horse. The driver enters the cock-pit by opening the gull-wing RS doors and by stepping over the door sill protectors with the illuminated manufacturer logo.

With the CK 63 RS, Carlsson once more affirms its expertise as an exclusive manufacturer of high-quality Mercedes automobiles. The new model is offered for 272,500 euros including V.A.T.
