2012 Mercedes-Benz S-Class Reviews

Vehicle Overview

Mercedes' flagship S-Class full-size sedan seats five in two luxurious rows. A number of different powerful engines are available, as are high-performance AMG editions. The S-Class shares luxury-sedan real estate with competitors like the Audi A8, BMW 7 Series and Bentley Continental Flying Spur.

New for 2012
For 2012, a diesel-powered S350 Bluetec all-wheel-drive version is available, and the S550 features a new 4.6-liter V-8 with direct injection that makes 429 horsepower.

Exterior
The S-Class receives no major styling changes for 2012. Exterior features include:

  • S400 Hybrid has 18-inch 10-spoke wheels
  • S63 AMG has 20-inch twin five-spoke wheels
  • Available LED daytime running lights


Interior
Chrome and wood accents adorn the inside of the S-Class, which has room for up to five people. As opposed to a console-located gearshift, the driver selects Park, Drive and Reverse via a stalk on the right side of the steering column. Drivers who wish to manually control the automatic transmission can use shift paddles on the steering wheel. Interior features include:

  • Standard "mbrace" telematics system
  • Comand system with 7-inch dash screen and center-console control knob
  • Split-view dashboard screen can show different content at same time for driver and passenger
  • Optional massaging front seats
  • Massive backseat
  • Optional infrared night-vision system projects black-and-white video image on instrument cluster display
  • Optional lane departure warning system and driver drowsiness monitor


Under the Hood
In addition to the hybrid V-6 and diesel V-6, available engines include two V-8s and two V-12s, all of which team with automatic transmissions. Mechanical features include:

  • S400 Hybrid has a 3.5-liter V-6 and a seven-speed automatic with a total system output of 295 hp
  • S350 has a 240-hp, turbocharged 3.0-liter diesel V-6 and a seven-speed automatic
  • S550 features a new 429-hp, 4.6-liter direct-injection V-8 and drives a seven-speed automatic
  • S600 powered by a 510-hp, twin-turbo 5.5-liter V-12 and features a five-speed automatic
  • S63 AMG has a twin-turbo 5.5-liter V-8 that makes 536 hp, works with a seven-speed automatic and includes a start/stop feature (optional Performance Package increases output to 563 hp)
  • S65 AMG uses a 621-hp, twin-turbo 6.0-liter V-12 and a five-speed automatic
  • Rear- or all-wheel drive


Safety
Safety features include Mercedes-Benz's Pre-Safe system, which can tighten the front seat belts, close the sunroof and side windows, and adjust passenger seats for optimal safety when it senses an impending collision. The S-Class can also get Distronic Plus adaptive cruise control and Pre-Safe Brake. Pre-Safe Brake works in conjunction with Distronic Plus radar signals and can slow the car automatically to lessen the severity of a collision. Standard safety features include:

  • Antilock brakes
  • Front and rear side-impact airbags
  • Side curtain airbags
  • Active front head restraints

Warranties Explained

Bumper-to-Bumper

Often called a basic warranty or new-vehicle warranty, a bumper-to-bumper policy covers components like air conditioning, audio systems, vehicle sensors, fuel systems and major electrical components. Most policies exclude regular maintenance like fluid top offs and oil changes, but a few brands have separate free-maintenance provisions, and those that do offer them is slowly rising. Bumper-to-bumper warranties typically expire faster than powertrain warranties.

Powertrain

Don't be misled a 10-year or 100,000-mile powertrain warranty doesn't promise a decade of free repairs for your car. It typically covers just the engine and transmission, along with any other moving parts that lead to the wheels, like the driveshaft and constant velocity joints. Some automakers also bundle seat belts and airbags into their powertrain warranties. With a few exceptions, powertrain warranties don't cover regular maintenance like engine tuneups and tire rotations.

Roadside Assistance

Some automakers include roadside assistance with their bumper-to-bumper or powertrain warranties, while others have separate policies. These programs cover anything from flat-tire changes and locksmith services to jump-starts and towing. Few reimburse incidental costs like motel rooms (if you have to wait for repairs).

Free Scheduled Maintenance

Some automakers include free scheduled maintenance for items such as oil changes, air filters and tire rotations. Some include consumables including brake pads and windshield wipers; others do not. They are typically for the first couple of years of ownership of a new car.
