What SIO Automotive does

SIO Automotive is a Turkish automotive parts manufacturer founded in 1991, specializing in the design, production, and sale of steering and suspension system components for cars and light commercial vehicles. The company operates a single-product-line business centered on chassis components, with a portfolio of 5,000+ reference products serving both automotive OEM manufacturers and the aftermarket distribution channel. Its production is anchored at a 30,000 m2 closed manufacturing facility in Ergene 2 OSB, Tekirdağ, integrating robotic and environmentally conscious automation systems, and is supported by an R&D Innovation Center operating for over 5 years.

The company operates as a wholly-owned subsidiary of German automotive parts conglomerate Wulf Gaertner Autoparts AG, which provides corporate backing and international aftermarket distribution reach. SIO Automotive holds the full suite of automotive-grade certifications — IATF 16949, ISO 9001, ISO 14001, ISO 10002, and ISO 45001 — enabling it to participate in OEM supply programs globally. It employs 600+ staff across production, engineering, and administrative functions and has positioned sustainability as a strategic pillar, with 10+ documented environmental initiatives.

Revenue is generated through direct B2B sales of manufactured steering and suspension components to OEM customers and aftermarket distributors; pricing is quote-based and not publicly disclosed. The go-to-market motion combines direct enterprise sales with content-driven demand generation via its corporate website, downloadable product catalog, and industry event participation. Geographic reach is concentrated in Europe with Turkey-based production, and the aftermarket channel extends reach through the Wulf Gaertner parent group's distribution network.
