Multiple people said Jungwirth’s position had been tenuous since Matthias Mueller was ousted as chief executive in April 2018. JJ, as he is known, oversaw “moonshot” projects such as Cedric, a concept autonomous van showcased at the world’s auto shows. He was Mueller’s choice to run autonomous projects and worked directly for VW Group rather than one of its 12 brands. CEO Herbert Diess was never fond of the structure, and in January he poached Alexander Hitzinger, a former executive at Porsche then at Apple’s “Titan” car project. Hitzinger now runs VW’s autonomy projects, including its “transportation as a service” work within the Volkswagen commercial vehicles unit.
