Mercedes has released the first teaser images of the 2012 SLK.

While the company didn't go into detail about the car, they announced it will offer an optional electrochromic glass roof dubbed Magic Sky Control.

When ordered, customers can darken the top glass panel in a matter of seconds via a switch located on the overhead console. As Mercedes explains, "The operating principle is based on the physics of a plate condenser: if the glass structure is subjected to an electrical voltage, particles in the structure position themselves so that light is able to pass through the glass. If the voltage remains switched off, however, the particles position themselves randomly. This partially blocks the light, and the glass remains dark."

Furthermore, even in transport mode, the roof blocks UV and infrared light which helps to keep cabin components (shifter, armrest, etc) up to 10 degrees Celsius (50 degrees Fahrenheit) cooler.
