Mercedes-Benz SLK 55 AMG Overview

At the top of the Mercedes-Benz 'pile' sits the SLK 55 AMG roadster, the ultimate open-top Mercedes-Benz aimed at sun-worshiping performance hedonists. Slotting above the 'mere' SL 63 AMG, the SL 65 features a 6.0 liter V12 engine that pumps out an astounding 612 horsepower, an eight horsepower bump from before. Even more impressive is the 738 lb-ft. of torque from the motor, a figure usually reserved for big rigs and maybe even tugboats. Because of all this torque and power, the SL 65 makes due to mercedes slk accessories like ultra-stout five-speed automatic transmission, rather than the six or seven-speed transmissions that seem de rigueur in high performance cars today. Still, Mercedes-Benz estimates that the SL 65 will hit 62 miles per hour in a mere 4.2 seconds. The SL 65 features the same new styling that dresses up the rest of the SL roadster lineup for 2009.
