Mercedes-Benz redesigns its flagship coupe for 2007, giving it fresh looks, more power, and added safety features. The '07 CL-Class is about 3 inches longer in wheelbase and overall length than the 2000-2006 generation. It shares its basic design with the Mercedes S-Class sedan. Two models are offered. The CL550 has a 382-hp V8 and 7-speed automatic transmission; it replaces the 302-hp CL500. The CL600 again has a turbocharged V12 and 5-speed automatic but now has 510 hp vs. 493. ABS, traction/antiskid control, front and rear side airbags, and curtain side airbags are standard. Newly standard is Mercedes' Pre-Safe system that tightens seat belts and applies additional braking force if sensors detect an impending collision. All CLs have Mercedes' COMAND system, which incorporates a video screen and console-mounted "joystick" knob to control audio, navigation, phone, and other functions; it also accepts voice commands. Newly standard on all CLs are rear obstacle detection and wireless cell phone link. Standard on CL600 and optional on CL550 is Mercedes' infrared Night View Assist, which projects onto an instrument panel screen a black-and-white image of objects beyond headlight range.
