In the late 1990s, a new type of Mercedes-Benz roadster hit U.S. showrooms: the SLK. Smaller than the SL, it offered more affordable entry to drop-top motoring, and also led the convertible segment's trend to retractable hardtops.
A 2012 redesign brought the SLK into its third generation, which features three models. The SLK55 AMG is the most powerful and quickest of the trio. It builds on the standard equipment of its SLK350 sibling with the enhanced performance of a 415-horsepower 5.5-liter V8, AMG wheels, sportier suspension and steering systems, stronger brakes, unique styling elements and sport seats. So equipped, this beast blazes to 60 mph in only 4.5 seconds.
