This paper presents an overview of the world automotive market in terms of: vehicle production, estimated values of metal formed products and steel tonnage for body parts, engines, transmissions, steering and suspension. Twin factors of globalisation and product modularisation are discussed and their likely implications for metal forming. The need/opportunities ratio for novel automotive metal formed products is introduced and the case is developed using the rotary forging process as an example. Some of the coclusions are: High volume metal formed products will only be manufactured competitively by those companies who invest in low cost production equipment. To have any chance of competing for automotive metal forming business, companies without the large volume production equipment will need to specialise in lower volume, high added value products. Rotary forging technology can produce novel shapes of high value metal formed products in flexible volumes, cost effectively. Typical value added components for specialist rotary forging manufacture are circular, have large changes in material cross section and significant changes in diameter.
