Within the corporate structure, the German Tech Centre will focus on ‘transversal technological topics’ and, in particular, vehicle development for the Opel and Vauxhall brands.These ‘transversal technological topics’ include advanced driver-assistance systems (ADAS), virtual development, AI and tools for efficiency enhancement, the Digital Lightning Hub, battery development – including battery safety – as well as software module development for the STLA Brain architecture. Developments from Rüsselsheim will be utilised across the entire Stellantis brand portfolio.As part of this restructuring, job reductions are also planned. “Of the current 1,650 engineers, around 1,000 employees will continue to be responsible for strategic topics at the Rüsselsheim Tech Centre based on their areas of expertise,” the statement said. Ralph Wangemann, Managing Director of Human Resources and Labour Director at Opel Automobile GmbH and Head of HR for Stellantis in Germany, informed the works council of the planned restructuring late last week. However, the measures will only be implemented ‘after the works council has been fully informed and consulted, and a constructive dialogue with the social partner has taken place.’According to Wangemann, the planned transformation of the development centre, despite the reduction of 650 engineering positions, is part of Stellantis’ strategic commitment to the Rüsselsheim site. “Our goal is to establish a strong German Tech Centre with sustainable responsibilities and a clearly defined purpose within the group’s global development network,” the HR Managing Director stated.Stellantis is currently developing the ‘grEEn campus’ in Rüsselsheim, the new home for Opel and Stellantis Germany. This modern and sustainable campus will include a research and development building, complete with a design centre. This investment underscores the company’s commitment to Rüsselsheim and to Germany as an industrial location.In 2018, Opel sold parts of its development centre, including 2,000 employees, to the French engineering service provider Segula Technologies. However, the majority of the affected Opel staff ultimately accepted severance packages, resulting in only 700 Opel developers transferring to Segula. In 2025, Segula Deutschland entered self-administered insolvency proceedings and further reduced its workforce in Rüsselsheim.stellantis.com
