Introduction: evolving strategies

� OEM focused on integration and marketing of complete vehicle

� Standardization of components but plurality of vehicle categories � integration effort

� Development of new key technologies

� Management of supplier organizations

� New competences

� Innovative solutions for production and processes

� Innovative products

� Management of the product integration in customer’s vehicle – extended competences

Increased pressure on OEM’s and automotive suppliers

The Driveline as complete System

Fonte: Internet

Mechanics, hydraulic, electronicClassic and innovative development methodologiesSingle components know howInteraction between components, interfaces managementComponents integrationKnowledge of the market, technical solution, Production technologies know how

Competences of the powertrain development partner :

The whole is greater than the sum of its parts



The Driveline as complete SystemThe whole is greater than the sum of its parts

The holistic view of powertrain development that includes engine, transmission and driveline is now well accepted. Current trends indicate an increasing range of engines and transmissions in the future with, consequently, a greater diversity of combinations. Coupled with the increasing introduction of hybrid vehicles, the scope for research, novel developments and new products is clear.
