The 40-year-old will call time on a decade-long partnership with the German manufacturer after this month’s final round of the Italian GT sprint series at Mugello.
“Every end is a new beginning!,” wrote Glock on his Instagram handle.
“Thank you BMW Motorsport, spending 10 years together around the world on the best race tracks you can dream of.
“I really enjoyed the intense time in DTM with those wonderful Class 1 cars and great wins and podiums.
“One of the highlights for sure was the 24h race at Spa-Francorchamps with Alex Zanardi! One of those Races I will never forget! #forzaalex
“I think everyone remembers the iconic battle against Gary Paffett @hockenheimring 2018! Everyone who has seen it knows that I am still burning for this sport and always will!
“Now it is time to move on.
“A special thanks goes to Jens Marquardt who was the key person behind this journey.
“Thanks to all my BMW Teammates in those 10 years. Lots of stories to tell but maybe later… in a book ;-)
“I will enjoy my last race in Mugello with @ceccatoracing and the legend Roberto Ravaglia @ravaglia.roberto
“So I close my eyes to old ends and open my heart for new beginnings.
“See you soon, Timo #glockmeifyoucan.”
Glock has spent the majority of his post-grand prix racing career with BMW, first linking up with the Bavarian marque in 2013 as part of its DTM programme.
The German was immediately up to pace in the popular touring car series, scoring a podium in only his third race and claiming a victory later in the year in the Hockenheim finale.
He went on to become a mainstay of BMW’s factory assault on the DTM, securing a best finish of fifth in the championship in 2018 and repeating that result three years later in 2020, the last season of Class One regulations.
However, Glock struggled for results in the DTM’s first campaign with GT3 cars in 2021, scoring just nine points all season and ending a distant 17th in the standings.
This marked the end of Glock’s nine-year stint in the DTM, although he did make a wildcard appearance at Imola in June with the blessing of BMW.
For most of the 2022 season though he has focused on his commitments in Italian GT with Ceccato Racing, where he is currently placed third in the standings with victory in the Monza season opener - and with a real shot of taking the title.
Over the years, Glock also represented BMW in a wide variety of enduros including the Spa 24 Hours, Bathurst 12 Hour and the Rolex 24 at Daytona.
