As we previously reported, its new AMG 5.5-liter V8 engine featuring cylinder shutoff combines the highest level of performance with the lowest possible fuel consumption. The SLK AMG engine offers a peak output of 415 hp and maximum torque of 398 lb-ft, the 2012 SLK55 AMG is positioned to outperform all of its direct competitors. Thanks to the AMG sports suspension with Direct-Steer system, Torque Vectoring Brakes and 3-stage ESP, as well as the AMG high-performance braking system, high performance driving is guaranteed every time you get behind the wheel. The 2012 SLK55 AMG will arrive in U.S. showrooms in early 2012.

Forming part of the third-generation of the SLK launched in June, the new AMG model catches the eye at first glance: distinctive AMG light-alloy wheels, exclusive AMG body styling with AMG spoiler lip and two chrome-plated twin tailpipes at the rear complement the classic roadster proportions, while adding a distinct athletic touch. The expressive design of the 2012 SLK55 AMG is both eye-catching and unmistakable.

The SLK55 AMG is the perfect embodiment of the new AMG brand claim of “Driving Performance”: in the compact high-performance Roadster segment there is nothing to compare to its combination of tangible driving dynamics, superior sportiness, unique high-technology and low fuel consumption. The SLK55 AMG accelerates from zero to 60 mph in 4.5 seconds, and reaches a top speed of 155 mph (electronically limited).

Helping to set new fuel efficiency standards for V8’s, the 5.5 liter engine combines low consumption figures with superior power delivery and the typical exhaust growl which only a large-displacement eight-cylinder engine can produce.

In line with its “AMG Performance 2015″ strategy, the new V8 engine continues to reduce both the fuel consumption and emissions of new models over the next few years – while reaching new heights with the central brand claim of “Driving Performance”. At the same time, AMG is also demonstrating its social responsibility with the M152 engine.
