Trailblazing racing driver Sabine Schmitz, the only female winner of the Nurburgring 24 Hours, has died aged 51.
Schmitz, who was widely known as 'Queen of the Nurburgring' and became a presenter on Top Gear, said last year she had been diagnosed with cancer in 2017.
She won the German circuit's endurance race, which takes place in part on the fearsome original banked Nordschleife, in 1996 and 1997 for BMW.
"The Nurburgring has lost its most famous female racing driver," the German circuit said in a statement.
"Sabine Schmitz passed away far too early after a long illness. We will miss her and her cheerful nature. Rest in peace Sabine!"
Formula 1 paid tribute to her on Twitter.
