The material is said to have a lower infrared transmission than glass which consequently helps keeping the passenger compartment comfortably cooler. This aside, PMMA is also been used in side and rear windows, roof panels, and more. Lotus Exige body parts made of CFK and ROHACELL® structural foam and plastic charge air ducts were fitted in the car engine.

PMMA-Based Racing Car Windshield
In an effort to provide light-weight and reliable protection to cars, Evonik’s PLEXIGLAS® polymethyl methacrylate (PMMA) is now used to make windshield in RED Motorsport’s Lotus Exige race car. Stone chip resistance in these windshields is claimed to be better than glass-made windshield. PMMA also reduces the weight of the windshield by as much as 40 percent, yet provide rigidity, transparency, acoustic properties and high UV and weathering resistance.
