Carlsson takes the Mercedes-Benz SL 63 AMG and adds 75 hp and a very intense matt black color varnish. The car gets a boost in torque too by 75 Nm and performance is boosted by suspension lowering of 30 mm and custom brakes and tires.

Performance tuner Carlsson has unleashed the SL CK63 RS, a 600 hp and 705 Nm of open-air driving pleasure version of the Mercedes Benz SL 63 AMG.

But don't call Carlsson a mere tuner. They prefer to be referred to as an "automobile manufacturer" specialising in Mercedes Benz models.

Their contributions to the SL 63 AMG include engine tuning the 6.2 liter V8 to increase both horsepower and torque by 75 points. Speed is cumbersomely limited to only 325 km/h. Because, you know, 326 km/h is where the fun really starts.

In any case, the C-Tronic Suspension takes this car 30 mm closer to the ground and a new super-stopping braking system is added. The performance package is rounded out with 255/30 ZR20 Dunlop SP SportMaxx tires at the front and 305/25 ZR20 on the rear wheels.

Although, the CK63 RS provides a considerable boost in overall performance over the SL 63 AMG, the exceptional work being done here is on the outside. The car comes varnished with "Stealth Titanium Graphite", a most intense matt black color which Carlsson claims is five times less glossy than conventional matt finish.

The interior also gets a low-volume coloring, with charcoal ultra suede lining the inside door panelling and the cockpit hood scoop.

Price is 272,500 euros including V.A.T..
