2013 Mercedes-Benz SLK-Class Reviews

2013 SLK-Class New Car Test Drive

The following review is for a 2012 Model Year. There may be minor changes to current model you are looking at.

Introduction

The 2012 Mercedes Benz S-Class remains the prototypical full-size luxury sedan, and the complete luxury package. It's suitable for quiet, rock-steady cruising at Autobahn mega-speeds, spirited drives through the countryside, unflustered dawdling through heavy traffic or chauffeured escape from the grind. S-Class safety systems are unparalleled, and this sedan is huge inside. 

The 2012 S-Class introduces some substantial changes. Among them: three new engines and a redesigned 7-speed automatic, all intended to improve fuel economy while preserving the requisite power and verve. However, the biggest news for 2012 is introduction of the first diesel-powered S-Class for North America since 1996. 

The S-Class competes with the Audi A8L, BMW 7 Series and, to a lesser extent, the Lexus LS, but the S-Class offers more model choices than any of those other models. The sport-tuned S63 AMG matches up with BMW Alpina B7, and the smaller but sportier-handling Maserati Quattroporte, Porsche Panamera and Aston-Martin Rapide. The S65 makes a less-ostentatious (and faster accelerating) alternative to Bentley's Flying Spur Speed. Mercedes offers the most engine choices in this class, and optional 4MATIC all-wheel drive. 

The 2012 Mercedes-Benz S350 BlueTEC is powered by a high-tech, low-emissions 3.0-liter turbo-diesel V6. It's arguably the smoothest, quietest diesel engine ever, almost imperceptible from the driver's seat, and its 455 pound-feet of torque allow the Mercedes-Benz S350 to scoot from 0-60 mph in 7 seconds. Based on the EPA's projected ratings of 20/31 mpg City/Highway, the S350 BlueTEC beats the next highest mileage car in this class by 20 percent (including a couple of hybrids), and that's with 4MATIC all-wheel drive as standard equipment. 

The 2012 Mercedes-Benz S400 Hybrid combines a gasoline V6 with an electric motor for nearly 300 horsepower, powering the car to an electronically limited top speed of 130 mph, and surpassing all but the new BlueTEC diesel in fuel economy. This mild hybrid won't run strictly on electric power. The motor assists the gasoline engine to conserve fuel and converts braking energy into electricity to power accessories The S400 Hybrid is EPA-rated 19/25 mpg. 

The 2012 Mercedes-Benz S550 gets a new, smaller twin-turbo V8, with more power (0-60 mph in 5.4 seconds), better mileage and optional all-wheel drive. The S600 is the most luxurious S-Class, powered by a 536-hp, 5.5-liter twin-turbo V12 fitted with a 5-speed automatic. 

The S63 AMG is finished by the in-house tuning department with appearance tweaks, 20-inch wheels and firmer sport suspension. The 2012 S63 AMG is powered by a 5.5-liter twin-turbo V8 generating 536 horsepower and 500 lb-ft of torque. It also features a unique clutch-operated 7-speed automatic. The S65 AMG is AMG's treatment on the V12 S-Class, with a 6.0-liter engine delivering 621 horsepower and 738 lb-ft of torque. It's one of the most powerful four-door cars in the world. 

The S600 V12 and the S63 AMG are both a second quicker than the S500, while the S65 AMG is quickest of all (0-60 in 4.2 seconds). Approaching its 186-mph speed limiter, the S65 is still pulling like a freight train. 

We've found all the S-Class models handle well for big luxury sedans. They are composed, responsive and stable at any speed. The Airmatic air suspension system has both automatic and manual controls for ride height and firmness. The transmissions offer multiple operating modes, for best comfort and economy or maximum driver involvement and performance, while brakes bred for the Autobahn have massive reserves at more pedestrian American speeds. 

Technophiles may revel in the best night vision system on the market, cruise control that will maintain following distance up to 125 mph or stop the car automatically, and seats that massage, cool and self-inflate under lateral loads. Even the least expensive model comes with everything most buyers want, including a navigation system and a high-grade, high-watt harman/kardon surround system with all the right hardware. 

Inside, occupants are surrounded by wood, leather and finishes befitting an expensive car, not to mention serene quiet at cruising speeds. The trunk is one of the largest in this class, and perfectly shaped for maximum storage, and the rear seat is truly expansive. It's also loaded with standard niceties, including lit vanity mirrors, ambient lighting and multiple air vents. The rear cabin can also be upgraded with adjustable, ventilated seats and a killer two-screen video system. 

The S-Class rolls near the tip of the luxury pyramid, at a premium but largely justifiable price. Whether you prioritize hybrid cleanliness or incinerating power, its general air of superiority makes a compelling argument to anyone shopping a true luxury sedan. The Mercedes-Benz SLK350 is the smaller and less-expensive of the marque's two-door roadsters. The SLK350 features a retractable hardtop that shuts out the weather when up and allows for the freedom of open-air driving in just 20 seconds. In price and performance the SLK350 competes with the Audi TT, BMW Z4, and Porsche Boxster. 

The 2012 Mercedes-Benz SLK-Class features fresh looks inside and out and a new engine, though the platform isn't substantially new. 

Initially, a new 3.5-liter V6 is the only engine available. It replaces another 3.5-liter V6, but adds direct engine and changes from a 90- to a 60-degree configuration, which is the ideal design geometry for a V6. Horsepower and torque are up slightly, but fuel economy is improved by 12 percent. The lone transmission is a 7-speed automatic that can be shifted manually with steering wheel paddles. 

Due in early 2012 is the SLK250, which will feature a 201-horsepower turbocharged 1.8-liter four-cylinder. Following soon thereafter will be the SLK55 AMG, which will get a new 415-horsepower 5.5-liter V8. 

In basic V6 form, the SLK350 is quite quick, but not as fast as higher end models from its competitors. The new engine has a pronounced exhaust note that is probably the rawest aspect of the car. 

Handling is impressive, though not quite as sharp as that of the Porsche and BMW competition. The steering isn't razor sharp just off center but it gets quicker as the steering wheel is turned thanks to Mercedes-Benz's Direct Steer. It's a great system that aids handling in sharp turns. While the Boxster and Z4 may be sportier, the SLK-Class is the most comfortable car in its class, with a quiet, stable ride. 

Inside, the SLK-Class offers the typical high-quality Mercedes-Benz cabin featuring an attractive design and top-notch materials. Room is good for all but tall drivers, who will want more seat travel. The folding hardtop limits trunk space, but there is still enough room for a weekend away. 

The 2012 Mercedes-Benz SLK350 delivers agile handling, ready power and a smooth ride. Driving enthusiasts, however, will be better served by the Porsche or the performance version of the BMW. 

Lineup

Safety related options include Attention Assist, which identifies the erratic steering corrections drivers make as they begin to get drowsy and triggers an audible warning. Active Lane Keeping Assist warns when the S-Class drifts from its lane, while Active Blind Spot Assist identifies vehicles not visible over the driver's shoulders. Both incorporate an intervention feature, helping correct the car's course if the driver doesn't heed the initial warning. Distronic Plus cruise control can automatically stop the car from up to 125 mph. Night View uses an infra-red camera, creating a black-and-white image of the road and people ahead in darkness, and projecting that image in the center of the dash. 4MATIC all-wheel drive improves stability in slippery conditions. The 2012 Mercedes-Benz SLK-Class is initially offered in only one model: the SLK350 ($55,675), powered by a new 3.5-liter V6 engine that makes 302 horsepower and 273 pound-feet of torque. The lone transmission is a 7-speed automatic that can be shifted manually with steering wheel shift paddles.
