Added to the list of standard equipment on the CL500 and CL600 for 2006 is the AMG Sport package, which consists of an AMG-designed body kit (side skirts, front and rear fascias) and 18-inch double-spoke alloy wheels with high-performance tires. In addition, Keyless Go (which allows the driver to enter and start the vehicle without removing the key fob from their pocket), a heated steering wheel, and an electronic trunk closer are now standard on the 2006 CL600.
