This special 2014 Ford Fusion features a rear window produced with polycarbonate glazing from Sabic Innovative Plastics, Pittsfield, Mass. Although still in the development stage, it’s said to be the first plastic rear window created for an actual production car. It allowed a 35% weight reduction (7.4 lb) over the 2013 model. The rear window is identical in geometry to the glass version in the Fusion production vehicle. This allowed Ford to test the two parts and compare their performance based solely on the material used.

Ford developed the lightweight concept vehicle with the U.S. Dept. of Energy’s Vehicle Technologies Program and Magna International’s Cosma subsidiary to illustrate long-term potential lightweighting solutions. Sabic contributed its Lexan PC glazing materials, advanced coatings technology, and engineering design expertise The concept’s rear window utilizes Sabic’s Exatec E9000 plasma coating for glass-like scratch and UV resistance.
