Carlsson has just unveiled its CK60 coupe, which is based on the Mercedes-Benz CL-Class. This revamped model sports a tuned V12 engine that produces an impressive 600hp @ 5000rpm and 1024Nm torque @ 3500rpm — rocketing it from 0-60mph in just 4.4-seconds. Other upgrades include a sports exhaust system and ultralight forged wheels. Few more pics after the jump. [via AutomotoPortal]
