2007 Mercedes-Benz S600

Completely redesigned for 2007, the S600 is now almost two inches longer than the previous year's S-Class models, and taller as well, providing more interior room. New design features include a V-shaped grille, distinctive wheel arches, and taut lines designed to project a more muscular and athletic profile.

But it's what's under the hood that makes the S600 the true the king of the hill in the Mercedes lineup. Power is provided by a 5.5-liter, 32-valve, turbocharged V12 engine that pumps out 510 horsepower, with plenty of low-end torque to ensure fast starts and aggressive driving, no matter the location or conditions. Shift buttons for the five-speed automatic transmission are located on the steering wheel, leaving the center console free for the communications systems.

In fact, the COMAND system controller, located on the center console, is one of several new features for 2007. A mouse-like device used to access a number of the S600's systems, the controller rotates clockwise and counterclockwise, as well as moving left, right, backward, and forward, enabling the driver to access and control the car's audio system, navigation system, telephone, climate control system, and some seating functions.

Also new are the advanced Bi-Xenon headlights with Active Curve Illumination. They provide enhanced safety by turning to follow the driver's steering wheel movements. In addition, the S600 is equipped with a Night View Assist night-vision system, which uses infrared technology to project an image of the road ahead onto a screen on the instrument panel.

Another new feature is the Distronic Plus adaptive cruise control system, an optional system that will automatically slow the vehicle if it gets too close to a vehicle ahead, and then return the vehicle to the set speed limit when the way ahead is clear. The Distronic Plus system will even bring the S600 to a complete stop if you reach a congested area.

Inside, such features as 14-way power-adjustable seats with four massage settings, leather upholstery, Burl Walnut trim, a wood- and leather-trimmed steering wheel, and four-zone climate control raise the level of luxury.

The safety features of the S600, as well as its comfort, styling, performance, and handling, draw high marks from drivers. Some even go so far as to call it the best luxury car in the world. Not everyone is impressed with the car's styling, however, with some calling it unimpressive, and even boring. But everyone seems to rave about the comfort of the back seats, noting that if you sit there, you'll never want to leave.
