The Mercedes COMAND system, a centralized computer interface with a dash-mounted flat panel screen, is also standard. It enables access to many of the car's accessories including GPS navigation, phone, climate controls, and other customizable features (exterior courtesy lights, seat settings and voice command setup). Bi-Xenon headlights are standard, too, as is Parktronic, a distance sensing parking aid. All CLs are equipped with ABC active suspension, which utilizes electro-hydraulic cylinders to control body roll and some damping functions.
The optional Premium 2 Package ($3370) for the CL550 4MATIC includes heated and ventilated front seats, a keyless entry system, multi-adjustable front seats fitted with pneumatic chambers that adjust cushion firmness and lumbar support, a night vision system with an in-dash screen, and a rear backup camera. A heated steering wheel ($470) is also available. A Sport Package ($5690) adds special aerodynamic pieces and larger, 19-inch wheels (18-inch wheels are standard). Or choose 19-inch wheels by themselves ($1230).
The CL63 AMG has the heated steering wheel, and the body kit, and includes 20-inch wheels as standard; Premium 2 equipment is optional ($2120). Optional for both V8 models are Distronic Plus distance monitoring cruise control with Parking Guidance and Blind Spot Assist ($2880), and an iPod integration kit ($425). Buyers seeking even more exclusivity can choose among two designo edition combinations of exterior color and interior leather and trim (Espresso or Graphite).
Most of the above are standard on the CL600. The only options it offers are the iPod kit, the two optional wheel choices, and the designo editions. Ditto the CL65 AMG, except that it, like the CL63 AMG, already comes with 20-inch wheels.
Safety features on all CLs include a pair of two-stage front airbags, a driver's-side knee airbag, two front side airbags, two rear side airbags, and side head-curtain airbags for front and rear passengers. There are seatbelt pre-tensioners for the front passengers' belts. Windows close automatically in a crash, and a sunroof closing feature activates in rollovers. Also standard: ABS with electronic brake-force distribution and automatic wet-weather drying, dynamic stability control, traction control, and Distronic cruise control. Optional safety equipment includes Distronic Plus distance-sensing cruise control with Parking Guidance and Blind Spot Assist. Next Page
