Mercedes-Benz S550 reviews

2009 Mercedes-Benz S550 Interior Features

The Mercedes S-Class boasts one of the most beautiful interior executions on the market today.

And it's relatively easy to learn how to operate. We solved all of the mysteries of a complicated luxury car's switch layout and control system without looking in the owner's manual. It's that easy. The COMAND system, located at the center of the dash, is used to operate the radio, telephone, entertainment system, navigation system, and vehicle systems.

The COMAND system uses a large, deeply hooded and high-mounted 16:9 ratio full-color display screen, with a console-mounted knob that twists and pushes to change categories and change settings. Everything is done with the twist-and-push controller that operates like the BMW iDrive or Audi MMI systems, only better. It's far easier to use and understand, even without resorting to reading the manual, and far more intuitive than the BMW and Audi systems. Select the vehicle systems and the display changes to a silhouette drawing of the car where you can customize 10 different settings to your preferences as easily as using a point-and-shoot camera.

The driver's door panel is packed with controls for windows and mirrors, including a folding function, and in this case they fumbled. The switches that select the left or right mirror to be adjusted or folded are so tiny that the average driver will probably hit both at once until he or she is used to it (they each light up with a red jewel to show you which side you're adjusting). The steering wheel makes the audio and other functions easy to use, with a pair of round controls in the spokes that can do up/down and left/right function selection and change, such as radio station, CD or MP3 track, volume, and muting.

Interior environment is controlled by a switch panel at the center of the dash, with four vents and an air conditioning system that is vertically layered and capable of focused, medium, or diffuse air distribution throughout the car, with two zones in front and two in the rear, each with its own controls. Oh, and that thing that looks like a folded-up wood-grained, chrome-edged cellular telephone, on the console just behind the COMAND interface, is exactly that: a telephone dialer.

Another wrinkle is a strip of ambient lighting in the cockpit that starts on the left door, goes all the way across the lower part of the dash, under the wood trim panel, and all the way back on the right door, creating a continuous ribbon of light that can be adjusted through five brightness levels by using the "Vehicle" portion of the COMAND system. A beautiful touch in a beautifully organized, visually exciting interior.

The transmission shifter operates like the one in the M-Class and R-Class SUVs: A tiny stalk on the right side of the column features up, down and in positions for Reverse, Neutral, Drive and Park modes, and all models come with three-mode shifting including Manual, Sport and Comfort shifting using the steering wheel paddles on the reverse side of the spokes, left for downshifts, right for upshifts. While we liked the brushed metallic interior panels very much, we didn't like the chrome tip on the shifter handle, because it's bright and glares like crazy on a sunny day. We prefer the brushed metal finish.

The CD/DVD system loads behind a panel under the environmental controls, and contains a slot for loading a PCM/CIA memory card to an internal hard-drive that will play up to 1,550 songs through the Harmon/Kardon 5.1 Logic 7 600-watt, 14-speaker surround sound system. The system is compatible with Apple iPod. And finally, the clock is placed at the epicenter of the instrument panel so that it's classic analog design that looks like a fine wristwatch, with bright trim and bright hands, can be seen by everyone in the car.
