Mercedes-Benz tests switchable roof for new SLK

The panoramic vario-roof MAGIC SKY CONTROL in transparent

Mercedes-Benz will introduce a new of switchable glass roof as an extra on the new SLK next year. The vario-roof with MAGIC SKY can – aside from being a mouthful – either be darkened or transparent at the touch of a button.

on the physics of a plate condenser, the glass structure of the roof is to an electric voltage, particles in the position themselves so that is able to pass through. If is no voltage the particles position randomly, darkening the glass and blocking the light. This the transparency of the glass to be altered at the of a button located in the vehicle’s console which controls a integrated into the front of the roof.

Mercedes says the roof is to provide an “open-air experience cold weather” as well as shade to prevent the interior of the car heating up in direct sunlight. the chrome domes of people myself the roof will block UV and infrared rays in mode, while insulation increases significantly and noticeably in mode, keeping interior such as armrests cooler by up to 10 Celsius (50 F) compared with green glass.

To test the technology, Mercedes-Benz to Death Valley in the U.S. prototype vehicles fitted the switchable glass roof. temperatures there regularly hit 50 degrees Celsius (122 F) in the and test engineers made the of these conditions, heating up the SLK for four hours around

Using a device known as a pyranometer, which measures the of exposure to sunlight, the team was to measure the effectiveness of the roof. an open roof the device a load of 1,000 to 1,100 W per meter from the sun. the transparent glass roof the dropped to 200 W, and when the roof was to darkened mode it dropped to 40 to 50W – one of the original value.

As you’d expect, this translated to relief from the with thermal images that temperatures in the region of the and shoulders were immediately and reduced when the roof was to darkened mode.

But Mercedes says passengers be the only ones to benefit the technology. The switchable glass should also take of the strain of the air-conditioning system, cutting CO2 emissions.
