TopGear.com.ph Philippine Car News - Mercedes-Benz launches SLK 55 AMG

It hasn't even been a week since Mercedes-Benz revealed the SLK roadster is getting a diesel engine that the German luxury carmaker announced it has created the most powerful SLK ever by squeezing the 5.5-liter AMG V8 engine under the car's bonnet.

With a peak power output of 422hp and a maximum torque of 540Nm, the SLK 55 AMG outperforms all its competitors as it can accelerate from zero to 100kph in 4.6 seconds before it reaches its electronically limited top speed of 250kph.

Despite these impressive performance figures, the SLK 55 AMG can run 11.905 kilometers per liter while emitting only 195g/km of carbon dioxide. The V8 engine also utilizes the Cylinder Management cylinder shut-off system to give the SLK 55 AMG the ultimate in performance with the lowest possible fuel consumption.

Other fuel-saving measures employed by the SLK 55 AMG are the Controlled Efficiency start/stop function and a generator management system, which uses the kinetic energy generated by braking or when the V8 engine is overrun to charge the battery instead of being wasted as heat in the usual way.

Putting the AMG engine's power down to the rear wheels is an AMG Speedshift Plus 7G-Tronic automatic transmission, which features three transmission modes: controlled-efficiency, sport and manual.

For the first time AMG is using an exhaust system that features an exhaust flap on each side to give the car an emotional sound when driven in a sporty manner and a more discreet engine note when driven conservatively.

To distinguish the range-topping SLK 55 AMG from the entire SLK lineup, it features a new AMG front apron with large air inlets and AMG-specific LED daytime driving lights. Inspired by the SLS AMG, the wide radiator grille features a large, centrally-positioned Mercedes star with the slats in the radiator grille and the lower cross strut on the front apron painted in a high-gloss black finish. Darkened clear-lens headlamps and darkened bicolour tail lamps also come as standard along with the distinctive AMG light-alloy wheels and specific AMG body styling like an AMG spoiler lip and two chrome-plated twin tailpipes at the rear to complement the car's classic roadster proportions while adding a markedly athletic touch.

The SLK 55 AMG also gets the the panoramic vario-roof with "magic sky control," which switches the glass roof's tint from light to dark at the press of a button.

The SLK 55 AMG is slated to hit the global market in January 2012.
