2008 Mercedes-Benz S-Class Review

High-tech luxury sedan blends power and prestige.

Reviewed by Automotive on


Given the success of its flagship sedan, it’s no surprise that Mercedes-Benz has changed very little in its 2008 S-Class line. Standard satellite is the only new feature for the illustrious S-Class, which continues to attract luxury-oriented buyers with its elegant design, powerful engines, and state-of-the-art engineering.

The S-Class is offered in four increasingly-sporty trims, each with a unique engine. The base S550 comes with a 5.5-liter V-8, the S63 AMG is equipped with a 6.2-liter V-8, the S600 with a twin-turbo, 5.5-liter V-12, and the S65 AMG with a six-liter V-12 making an impressive 604 horsepower. Front-wheel drive is standard; however, the S550 is also available with all-wheel drive. Inside the cabin, premium leather, adaptive seats, and a long list of standard technology features make for a comfortable ride. While the S-Class can’t match the agile driving dynamics of top-of-the-line sport sedans, its air suspension and sharp handling make it one of the best performers in the luxury sedan segment.

What's New

With the exception of standard satellite radio, nothing is new about the 2008 Mercedes-Benz S-Class.


The 2008 Mercedes-Benz S550 comes equipped with 18-inch wheels, a chrome grille, bi-xenon headlights, foglights, a remote-operated power sunroof, a power rear sunshade, variable intermittent rain-sensing windshield wipers, a rear defogger, cargo tie-downs, and an air spring suspension. An AWD system and Mercedes’ Active Body Control (ABC) active suspension are optional. Upgrading to the S63 AMG adds the larger V-8, 20-inch wheels, performance tires, bigger brakes, the ABC suspension, and distinctive exterior details.

Both V-8 trims are available with optional keyless entry and ignition and an infrared night-vision assistance feature. An AMG package outfits the S550 with the S63 AMG’s wheels and trim, while a performance package provides the S63 with a limited-slip rear differential and increases the top-speed governor from its normal 155 mph to 186 mph. The S600 and S65 AMG come with all the features of the V-8 trims, plus its respective V-12 engines. The S600 also adds a fixed-glass rear sunroof.


Trimmed in premium leather and high-quality wood, the cabin of the 2008 Mercedes-Benz S-Class is elegant and refined. Seats are well-bolstered and controls and equipment are laid out intuitively, though some have complained that the low-set turn signal stalk can be difficult to reach.

Standard interior features on the base S550 include leather upholstery, a leather tilt-and-telescopic steering wheel with transmission and audio controls, an alloy-trimmed shift knob, 14-way adjustable front seats with lumbar support and multiple heat settings, memory settings for three drivers, a reverse-tilt passenger mirror, power-adjustable heated mirrors, power locks, one-touch power windows, retained accessory power, a universal remote transmitter, 12-volt power outlets, interior air filtration, dual-zone climate control, extended cabin heating, a trip computer, a compass, and an external temperature display. Technology features include a hard-drive-based navigation system, a COMAND multimedia interface, Bluetooth, a voice-activated phone, Mercedes’ TeleAid emergency communications system, satellite radio, and a 14-speaker 600-watt Harman Kardon surround-sound system with a CD player and MP3 playback.

The S63 AMG adds sport seats and aluminum trim. Both V-8 models are eligible for available ventilated front seats with massage settings or a Rear Seat Package, which adds four-zone automatic climate control and heated and cooled rear seats. All of the above features come standard on the S600 and S65 AMG.

Performance & Handling

The 2008 Mercedes-Benz S550 comes fitted with a 5.5-liter V-8 producing 382 horsepower and 391 lb-ft of torque, while the S63 AMG features a 6.2-liter V-8 making 518 horses and 465 lb-ft. Both V-8s are matched to a seven-speed automatic transmission, but the AMG version has been tweaked for faster gear changes. Upgrading to the S600 adds a 5.5-liter, twin-turbo V-12 churning out 510 hp and 612 lb-ft. The top-of-the-line S65 AMG is powered by a six-liter V-12 producing an eye-popping 604 horsepower and 738 lb-ft of torque. Each V-12 is paired to a five-speed automatic gearbox.

At 4300 pounds, even the lightest of S-Class models is still undeniably hefty. However, the S-Class’ high-tech air suspension manages to minimize body roll and bumps while its sharp steering lends a sporty feel.


As with most everything else about the 2008 Mercedes-Benz S-Class, safety features are state-of-the-art. Standard safety equipment on all S-Class models includes front and rear head airbags, dual front and rear side-mounted airbags, front whiplash-reducing head restraints, cornering lights, dusk-sensing self-leveling headlights, night-vision assistance technology, stability control, traction control, anti-lock brakes, emergency braking assist, brake drying, tire pressure monitoring, and pre- and post-collision safety systems.
