The new “smart fortwo” epitomizes urban mobility and, with its low fuel consumption and low CO2 emission levels, is a shining example of environmental friendliness. One of the car's highlights is its lightweight roof module made of Makrolon® AG2677, a polycarbonate (PC) from Bayer MaterialScience AG that is tailor-made for automotive glazing. “With an area of around 1.2 square meters, this is to date the largest polycarbonate roof module fitted in a production-line vehicle anywhere in the world,” says Dr. Sven Gestermann, Key Account Manager Automotive Glazing for Europe at Bayer MaterialScience. The plastic module is manufactured by Webasto AG, which is based in Stockdorf near Munich and is one of the world's leading manufacturers of roof modules and sunroofs for the automotive industry.
