Timeline of an industrial success, the result of a sustainable vision

A graduate of the École Nationale d’Horlogerie in Cluses, Yves Bontaz (1938-2018) sets up his bar turning workshop on the family farm. Initially a local subcontractor, he soon establishes direct contacts with French sub-assembly manufacturers and carmakers.

The company focuses on the production of braking systems and engine sub-assemblies, mainly for European brands. The Bontaz group strengthens its design office in Haute-Savoie and becomes a genuine partner of car manufacturers.

Having become a Tier 1 OEM supplier, Bontaz works with the world’s leading automotive manufacturers. The first subsidiaries are set up in the Czech Republic (1995), Brazil (1999), China (2000), the United States (2001), Korea and Japan (2005), and Tunisia (2008).

Now a leading global supplier of automotive hydraulic functions, Bontaz opens new subsidiaries in India (2010), Morocco (2012) and Portugal (2018). The sites enhance their versatility by integrating engineering, production, assembly and marketing activities.

Bontaz is keeping pace with changes in mobility and diversifying into high-potential markets such as electric vehicles, fuel cell engines and soft mobility. At the same time, CSR activities are being structured and accelerated with a view to achieving carbon neutrality by 2050.
