The second generation CL-Class used the C215-chassis designation and was manufactured and marketed by Mercedes from 1998–2006 as the company's flagship model, a two-door, four-passenger coupé.

Based on the 1998–2005 Mercedes-Benz S-Class (W220), it uses an 8 in shorter wheelbase. Its unique unibody construction used a steel floor pan, chassis rails and A pillars along with a bonded aluminium roof and rear wing sections, magnesium door frames and composite plastic used for the boot/trunk and front wings.

Sales in Germany started in August 1999 for the CL 500 V8.

The C215 exterior design and active suspension was previewed by the Mercedes-Benz F200 concept in 1996.

 * naturally aspirated (NA) V8-powered CL 500
 * NA V8-Powered CL55 AMG, the supercharged V8-powered CL55 AMG

Features and equipment
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.

Standard equipped included hydropneumatic suspension, the Active Body Control or 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. Driver controls can enable the system to increase the car's ground clearance in three increments for driving on difficult terrain. The suspension will lower the vehicle 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 on introduction of the 500 PS bi-turbo V12. This system allowed the CL 600 to achieve better fuel economy than the comparable CL 500 when not istself [sic] (option for the V8), especially on the road when six-cylinder operation could be activated. Conceptually, the engine is two Mercedes six-cylinder series engines mated to a common crank with separate engine monitoring systems.

Cars with the Designo option were available in exclusive colours and with custom interior appointments, including an optional natural stone veneer.

Safety
In 2003, engine availability was revised, and the cars were upgraded with Pre-Safe precrash system and a DVD-based navigation system vs CD-based COMAND system. The CL 55 AMG became supercharged allowing the car to accelerate from 0-60 mph in 4.27 sec according to Motor Trend and the V12 CL 600 had turbochargers added and a slight engine capacity reduction, from 5786 cc to 5513 cc. Both cars produced 500 PS. Albeit the CL 600 Bi Turbo official power figures were understated to preserve sales of the CL 55 AMG Kompressor models. The more powerful CL 65 produced 612 PS. The top speed of the car was limited to 250 km/h.

Standard equipment included front and rear side curtain airbags. In total, the C215 features 8 airbags: 2 frontal (driver and passenger), 4 side airbags (one for each passenger, optional for rear seats) and 2 window-airbags. LED brake lights became standard.
