This was a tribute to the modified Safety Car version used in Formula One during the and seasons. The engine was a naturally-aspirated 5.4-liter V8 delivering 354 bhp at 5,500 rpm, and 391 ft lbs torque at 4,100 rpm. This was the first road car to feature full Ceramic Brembo Vented and Cross Drilled Disc Brakes. From 2000 through 2002, the V12-equipped cars featured a cylinder deactivation system called Active Cylinder Control. The feature was dropped when the Bi-Turbo V12 was introduced.

Car & Driver's acceleration test delivered a 0-60 time of 4.3 seconds. The more powerful CL 65 (2004-2006) produced . The top speed of the CL 65 was limited to .
