2012 Mercedes-Benz S-Class Review

KBB Editors

By KBB Editors

Updated December 23, 2019

Our editors drive and evaluate hundreds of new cars every single year, turning thousands of miles and countless hours behind the wheel into helpful reviews, ratings, and comparisons. They also have lives outside of work, or so they think. You’d be surprised what you can learn by hauling a dirt bike, hunting for a wayward sippy cup, or just packing the trunk full of groceries.

Pros

The Mercedes-Benz S-Class is the ultimate and universal automotive badge of style and success. With its rich interiors and plethora of amenities, the 2012 S-Class is one of the few cars that might be more enjoyable to ride in than to drive.

Cons

While the 2012 S-Class sedan’s luxury credentials are not in question, some may find the car’s image more Wall Street than Rodeo Drive. If you’re a young entrepreneur who has made it big, a more exotic Maserati Quattroporte, or even the Audi S8, might feel a little less conservative.

What's New?

Diesel power comes to the 2012 Mercedes-Benz S-Class sedan with the introduction of the new S350 BlueTEC sedan. The S550 receives a new 4.6-liter twin-turbocharged engine producing more power and better fuel economy than last year’s 5.5-liter V8.

The Mercedes-Benz S-Class sedan isn’t just a means of transport, it’s a status symbol, a message to all who look upon it that its owner has arrived and arrived big. Setting the benchmark for the industry, the 2012 Mercedes-Benz S-Class sedan comes in a variety of flavors, although the S550 is so loaded with features and power it’s absurd to classify it as a "base" model. The S-Class lineup includes a super car in the V12-powered S600, the all-new clean diesel S350 BlueTEC, the environmentally-sensitive S400 Hybrid and two Teutonic terrors outfitted by AMG, the S63 and S65 AMG. In all, the 2012 Mercedes-Benz S-Class line continues to offer the best in performance, safety, comfort and prestige. Then again, for a car with a starting price for the least-expensive model well over $90,000, one would expect no less.

2012 Mercedes-Benz S-Class Pricing

2012 Mercedes-Benz S-Class pricing starts at $12,474 for the S-Class S 400 Hybrid Sedan 4D, which had a starting MSRP of $92,725 when new. The range-topping 2012 S-Class S 65 AMG Sedan 4D starts at $25,834 today, originally priced from $216,850.

The Kelley Blue Book Fair Purchase Price for any individual used vehicle can vary greatly according to mileage, condition, location, and other factors. The prices here reflect what buyers are currently paying for used 2012 Mercedes-Benz S-Class models in typical condition when purchasing from a dealership. These prices are updated weekly.

Driving the Mercedes-Benz S-Class

When driving the 2012 Mercedes-Benz S-Class, one experiences two very distinct personalities. On the one hand, the S-Class is a surprisingly agile automobile, contradicting its enormous size with a highly responsive chassis and such clever electronic assists as MB’s Active Body Control. On the flip side, there is the passenger experience which, for some owners, means they experience the S-Class only from the back seat. The 2012 S-Class sedan floats over road imperfections and cocoons its occupants from nearly all external noise. The new 4.6-liter V8 is silky smooth, delivering its 429 horsepower through a newly-improved 7-speed automatic transmission. The 4MATIC all-wheel-drive system (AWD) is standard on the S350 BlueTEC, which offers better fuel economy and acceleration than the S400 Hybrid. Those who equate performance with prowess will likely enjoy the S600’s V12 engine or, better still, the 4.3-second zero-to-60-mph run and 186-mph top speed of the S65 AMG. Those with strong environmental concerns can still ride in luxury in the 2012 Mercedes-Benz S400 Hybrid. With its seamless mild hybrid powertrain and modest 3.5-liter V6 engine, this green luxury car offers a nice, easy feel with ride and handling similar to the S550.

Interior Comfort

Following the tradition of the great European sedans, the 2012 Mercedes-Benz S-Class interior is a study in reserved elegance and clean design. Seating in the S-Class provides exceptional head, hip and legroom plus nearly prefect seating positions and ergonomics. If you can’t get comfortable in an S-Class, you should take up walking. Technology is the buzzword for the S-Class interior, with such interesting features as an available Splitview display that allows the driver to view one source, such as navigation, while the passenger can enjoy another, such as a DVD movie. The S-Class seats are covered in premium leather with elegant sewing and stitching patterns. Rear-seat passengers can enjoy a host of amenities, including DVD entertainment and climate and audio controls.

Exterior Styling

The 2012 Mercedes-Benz S-Class is little changed from last year, retaining its athletic bulging fenders, graceful arching beltline and aero grille with stand-up hood ornament. LED-style daytime running lights (DRL) line the lower half of the headlamps, while integrated turn signals reside outside the side mirrors. Toward the rear, there is a slight hint of BMW in the raised bustle-style trunk lid, but the horizontal-striped tail lights are pure Mercedes-Benz. The S400 Hybrid and S350 BlueTEC trims wear additional badging to set them apart from the V8 trim levels.

Favorite Features

Active Body Control (ABC) with Crosswind Stabilization
The 2012 Mercedes-Benz S-Class sedan’s active suspension continually adjusts to the irregularities of the road, allowing the S-Class to optimize driving dynamics while offering an unprecedented level of ride quality. Crosswind stabilization adds further balance to the car by distributing wheel loads in order to maintain directional stability through strong lateral wind gusts.

Splitview
Located atop the 2012 S-Class’ center stack, this innovative dual-screen interface allows the driver and front passenger to view different content at the same time. For example, the front passenger can watch a movie while the driver utilizes the navigation system.

Standard Features

The roster of notable standard equipment for the 2012 Mercedes-Benz S-Class sedan begins with Mercedes’ COMAND multi-media interface with CD/DVD player, SD card slot and USB interface. Music is piped in via 14 speakers wired to a 600-watt harmon/kardon Surround Sound system. Seats are covered in rich leather, and the automatic climate control includes separate settings for the front footwell area. Standard safety features include Attention Assist, which monitors driver alertness; Torque Vectoring Brake, which initiates rear-wheel braking for greater stability through corners; a Pre-Safe pre-collision system; and a knee airbag for the driver. The S400 features a hybrid gauge and an animated flow-of-power graphic display.

Factory Options

The 2012 Mercedes-Benz S550 sedan has an enormous list of optional equipment and features, many of which fall under the category of Assistance Systems, high-tech driver aids that primarily have a focus on safety. There’s Speed Limit Assist, which recognizes speed limit signs and alerts the driver of the posted miles per hour. Crosswind stabilization counters the effects of gusty weather and helps keep the car on its intended path. Night View Assist Plus spots pedestrians in low-light situations, and radar-based Distronic Plus Adaptive Cruise Control helps maintain a safe distance with traffic ahead. This sedan is nothing short of a technological showcase and masterpiece.

Engine & Transmission

The 2012 Mercedes Benz S-Class sedans now offer the broadest range of power, performance, and fuel economy to date. The S550 will, to many, be the most appealing of the model line due to its smooth and strong 4.6-liter twin-turbocharged gasoline direct injection V8, yielding 429 horsepower and 516 lb-ft of torque, and its lower price; it’s neither under- nor over-powered. The S600 and the AMG models can be a bit overwhelming, while the S400 Hybrid feels somewhat labored during harder acceleration. A nice middle ground is the S350 BlueTEC, which features a V6 turbodiesel with 455 lb-ft of torque and an impressive 31 mpg highway fuel economy rating. For those who prefer an eco-friendlier alternative, they should opt for the S400 Hybrid, but expect a significant compromise to performance.
