Our experience in using plastics in car design. New applications, Alfa Romeo Alfasud, VW Rabbit and Scirocco, Lotus Esprit, Lancia Delta, B M W Ml, Fiat Panda, D M C De Lorean, Medusa. The use of plastics makes the designer's work easier and contributes to weight reductions in the face of energy problems. The passenger compartment must not suffer because of drag problems. Plastics play a leading role but not an absolute one. They must progress step by step through quality improvement, especially as far as versatility, aesthetics, functionality, weight and costs are concerned.
