Last year, Schmitz revealed that she had been battling cancer since 2017.
The Nurburgring confirmed the racing driver’s death on Twitter.
They said: “The Nurburgring has lost its most famous female racing driver.
“Sabine Schmitz passed away far too early after a long illness. We will miss her and her cheerful nature. Rest in peace Sabine!”
Speaking of her cancer battle last year, Sabine said on social media: “Many of you have probably wondered why I was on the list of participants on our Porsche in the NSL and then didn’t drive after all.”
