Vehicle industry researchers still know surprisingly little about what happens to a foetus in a car crash so, to expand engineers' and designers' understanding in this area, Volvo Car Corporation has developed the world's first official computer model of a pregnant crash dummy. This 'virtual' crash dummy is a woman at a late stage of her pregnancy, since that is when the unborn baby is at greatest risk in an accident. The basic geometry was completed in January and much time has been devoted since then to refining the model.
