The Mercedes-Benz CL 65 AMG is the flagship model of the second generation CL Class, codenamed C215.
The CL-Class coupés come equipped with the very latest in Mercedes-Benz technology, and along with the S-Class sedans the CL coupés receive new technological features.
C215 was the second car (after the W220 S-Class) with Distronic: the first worldwide radar-assisted Autonomous cruise control system. It was the first car in the world with both low beam and high beam (Bi-Xenon) High Intensity Discharge headlamps.
The C215 was standard equipped with the hydraulic Active Body Control (ABC) system. It is technically more advanced than standard Airmatic air suspension found on the W220 S-Class sibling, and keeps the car level even in fast corners, provides a comfort and sports setting. Also, the car height can be increased by using a button, increasing ground clearance (3 settings) for driving on difficult terrain, lowers automatically at higher speeds.
From 1999 through 2003, the V12-equipped cars featured a cylinder deactivation system called Active Cylinder Control. The feature was dropped when the 500 PS (368 kW; 493 hp) bi-turbo V12 was introduced. This disactivation feature allowed the CL 600 to get better fuel economy than the comparable CL 500 (when not equipped with ACC itself, an option for the V8), especially on the road where the six-cylinder operation could be effectively used. Essentially, the engine is two Mercedes six-cylinder series engines mated to a common crank with separate engine monitoring systems.
