The former F1 driver has had the official top job for the Australian Touring Car Championship / Supercars since 1987.
However, the Bathurst 1000 this weekend will be his last race in that role before it hands over to James Taylor.
“After thinking about this decision and discussing it with my loved ones, I have come to the conclusion that it is time to break up,” said Schenken.
“It was a privilege to have been in the Supercars Championship for so long and to have worked with so many wonderful people during that time.
“There are so many great memories that I will cherish and I will miss not being the race director at every event.”
Schenken will continue to work with Motorsport Australia and the FIA in other roles including serving as FIA Platinum Circuit Inspector, Chairman of the Organizing Committee of the Australian Formula 1 Grand Prix and Clerk of the Course.
“Of course I will continue to stay for them [Supercars] Race Control team, in case they want to chat or debrief, as I do with many officials around the world, ”added Schenken.
“As I still hold a leading role at the FIA and also at Motorsport Australia, I look forward to working on various projects in the coming years and looking after the next generation of officials.”
Eugene Arroca, CEO of Motorsport Australia, paid tribute to Schenken’s decades of service to supercars.
“Tim has such a big stake in the Supercars championship and is highly regarded,” said Arocca.
“He can certainly take credit for the professionalism with which these events are now being conducted and carried out.
“We saw how Tim supported Michael Masi as a mentor, who was able to seamlessly take on the role of Formula 1 race director, which proves the professionalism of Supercars race control.
“Tim deserves a sincere thank you from everyone in the motorsport community and we look forward to working with him at Motorsport Australia for years to come.”
Sean Seamer, CEO of Supercars, echoed Arocca’s thoughts.
“It was a pleasure to see Tim lead the team in race control and on behalf of everyone at the Repco Supercars Championship we congratulate and sincerely thank Tim for his contribution to our category over so many years,” he said.
“There are only a handful of people who would have competed in as many races as Tim, and his knowledge and experience has been invaluable to so many during his journey in supercars.
“Tim left such a legacy to the Supercars government and we will miss his friendship and presence on the race committee.”
