The new Mercedes-Benz SLK55 AMG, the most powerful car on the SLK class with 5.5-liter V8-cylinder engine that combines performance and modest fuel consumption. forms a sporty and aerodynamic body makes SLK 55 AMG can be sped up. with an impressive blend of white color is luxury cars. driving performance ensured thanks to the AMG sports suspension with Direct-Steer system, Brake Torque vectoring and 3-stage ESP ®, as well as high-performance AMG braking system
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).
Feature of SLK55 AMG :
SLK55 AMG has a feature that uses high-tech. performance has a direct injection gasoline engines other features at 2900 psi pressure, combustion and piezo injectors, all in conjunction with map-controlled shut-off cylinder technology, an all-aluminum crankcase with sharpening. stop / start system and power management – while revving to a maximum speed of more than 7,000 rpm. All these features lead to a high thermodynamic efficiency is important for high fuel efficiency and low exhaust emissions.New AMG Engine :
on a new engine the AMG 5.5-liter V8 engine uses an aluminum construction, weighing only 412 pounds is the result of compromise lightweight construction methods. Bearing cover for the crankshaft main bearings are gray cast iron, and bolted to the crankcase, as well as on the side, for high rigidity.optimize efficiency:
- weight-optimized cast aluminum pistons with special piston skirt coating
- special ventilation holes in the crankcase
- oil pump with electrically controlled pressure stage
- separate oil pump for cylinder shut-off as a controllable, low-friction vane cell pump
- engine cooling using especially efficient cross-flow principle
- electronically controlled fuel pressure, fully variable and demand-related between 1,450 and 2,900 psi
- Transmission of AMG system :
the AMG SPEEDSHIFT PLUS 7G-TRONIC automatic transmission which features three transmission modes: “Controlled Efficiency” (C), Sport (S) and Manual (M). The automatic rev-matching function when downshifting as well as the brief, precisely defined interruption of ignition and injection when upshifting under full load shorten shift times and increase emotional appeal. A double turbine torsional damper with centrifugal pendulum adapts to engine speed and helps minimize vibrations in four-cylinder operation as well as enhances comfort.
