Toyota Motor Manufacturing France is planning a major development project at its Onnaing site (59) including the adoption of a new platform developed by the Toyota Group. In addition to significant investments over the period 2017-2021, the company would consider creating jobs in the order of 300 new CDI contracts in addition to the current 3,000 employees. Indeed, the challenge will be to ensure the production of two models with the latest technologies while retaining, or even developing, the advantages of the site: flexibility, compactness, environmental footprint, quality of working life and skills development. Meeting such a challenge will require the use of many developments, tests and innovations in both processes and organisation.
