Seidl said: “I am delighted to welcome James back home to Hinwil asꩵ he joins us to shape 💟the future of this team. 

“The operation he will find has changed a lot since 𒁃his time here, but the same drive, the same commitment that contributed to making the team successful in his previous experience are still the same: I am sure that, together with this very talented and committed team, we will be able to continue on the path of growth on which we have embarked. 

“James’s appointment is a crucial step on this journey: he has an outstanding amount of experience in the sport, not just as Technical Director, but also in v🌱arious other roles within the technical💝 organisation of a team. 

“He will lead the transformation process of the technical side of the team, giving us the 🦋tools and d🐲irection we need to tackle the future. 

“I also want to thank Jan for📖 his precious contribution to taking Sauber to where it is now, following our most successful season in a decade, in which we climbed to sixth place in the Constructors’ Championship.”
