2009 Mercedes-Benz S-Class: Overview

Vehicle Highlights

The 2009 Mercedes-Benz S-Class adds a few new features. Four rear-wheel-drive models are offered along with one that has Mercedes' 4Matic all-wheel drive. The S550 and AWD S550 automatic have a 382-hp 5.5-liter V8. The S63 has a 6.2-liter 518-hp V8. The S600 has a turbocharged 5.5-liter 510-hp V12, and the high-performance S65 has a 6.0-liter version of that engine with 604 hp. All come only with an automatic transmission: A 7-speed in S550/S550 4Matic and S63, a 5-speed in the S600 and S65.

The S-Class suspension automatically adjusts for firmness and load leveling. Available safety features include ABS, traction control, antiskid system, curtain side airbags, and front and rear side airbags. Mercedes' Pre-Safe system is also standard; it senses an impending collision and tightens the seat belts and applies additional braking force. Also included are Mercedes' Tele Aid assistance and its 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. The S63 and S65 are tuned by Mercedes' AMG high-performance division and include sport suspension, sport exhaust and seats, and specific trim.

Available features on S-Class include ventilated and massaging front seats, heated and ventilated rear seat, and keyless access and starting. Also offered is a rearview camera and Mercedes' Distronic Plus adaptive cruise control. New for 2009 is Mercedes' Parking Guidance system--which assists drivers with parallel parking--and Blind Spot Assist, which alerts the driver to the presence of another vehicle in the car's blind spots. The S600 has a restyled optional 19-inch wheel set. All S-Class cars receive steering-wheel shift paddles, which replace gear shift buttons.
