Magic Sky Control

For the first time there will be said of Mercedes -Benz Magic Sky Control of automotive mass production. It is a switchable glass roof, which was previously only known from the Maybach. The difference between normal glass roofs is that the Magic Sky Control keeps the heat and the sun's rays from the interior; you can darken or variable but also brighten. In the on mode, the temperature on interior parts such as armrests by up to 10 degrees Celsius compared with conventional green glass. The roof works by the physics of a plate condenser: When a voltage is applied to the glass structure to align particles in the glass structure made so that light can pass through the glass. If the voltage remains switched off, however, the particles remain randomly oriented. Thus, the light is partially blocked, and the glass remains dark. Accordingly, the interior heats less and the air conditioning system is reduced when the roof is dark.


As an alternative to normal wind deflector, a new wind deflector system called Airguide was developed for the third -generation SLK roadster. This is strictly a pivoting draft- Schott, consisting of attached to the roll bars clear plastic discs; to prevent air currents, they are pivoted towards the vehicle center.


At launch there are three petrol engines with direct injection to choose from. The two 1.8 -liter, turbocharged inline four- cylinder petrol engines in the SLK 200 and SLK 250 make 184 hp and 204 hp. The preliminary top model SLK 350 comes to a power output of 306 hp from 3.5 liters capacity. Except for the entry-level model SLK 200, which comes standard with a 6- speed manual transmission, have the two more powerful models in the market starting on the advanced 7-speed automatic transmission 7G- Tronic Plus, which is available on request for the SLK 200; from December 2011, the SLK 250 is delivered from the factory with the 6- speed manual transmission. In addition, all models come standard with the ECO start -stop system. An AMG version was presented at the IAA 2011, this version has a development of cylinder deactivation on. .
