Tuned to deliver 700 horsepower, the Carlsson CLS63 AMG is capable of hitting 212 mph.
German tuner Carlsson will reveal its CLS63 AMG at next month's Geneva Motor Show. Dubbed the CK63 RSR, it's a project that's been months in the works. The headline figures are 700 horsepower and 737 pound-feet of torque - electronically limited to preserve the gearbox and drivetrain, which can only take so much abuse. A new intercooler system and additional water and oil coolers help manage all the extra power, while the seven-speed transmission comes with a thermostatically-controlled oil cooler.
0-62 mph comes in at 3.9 secs, 124 mph is passed after 11.6 secs, and top speed is rated at 212 mph. A high-performance stainless-steel sports exhaust with catalytic converters comes with a remote-controlled sound valve, so whether cruising through town or thrashing along country lanes, the right noise can be enjoyed at the push of a button. Handling has been brought in line with the power increase by fitting a bespoke adjustable suspension, lowering the car by 30mm and widening the front track by 25mm. Carlsson monoblock 1/10 alloys come in 19- and 20-inch diameters, while upgraded brakes help bring the rapid sedan back under the speed limit.
The styling of the four-door coupe is accentuated by a carbon-fiber front lip spoiler, black stainless-steel mesh inserts in the intake grilles, and a rear carbon valance insert. Also at the rear is an electrically-retractable spoiler, extending automatically at 62 mph and manually at any speed. Mocha Brown Leather, Brown Alcantara, carbon fiber and natural wood are used in the handcrafted Carlsson Signature Line interior, which also boasts aluminum sill plates with blue illuminated logos and aluminum door locking pins.
