"Over the past couple of months, my thoughts of retiring have been stronger, and therefore, it feels right to inform you today that I am retiring from motor racing," Kristensen told Autosport. "I still feel I am in peak physical form and possess the necessary mental toughness both in and outside of the car: it has been important for me to stop while I am still strong and able to deliver top performances at Audi."
While the World Endurance Championship's season-ending race at Interlagos on November 30 will be Kristensen's last as a driver, it won't be the end of his long-running association with Audi. According to Autosport, TK will take on a new role as an ambassador for the German marque and will work with team's drivers in an unspecified role.
While best known for his time with Audi, Kristensen also scored Le Mans victories behind the wheel of Porsche and Bentley racers, and campaigned two 24-hour races with BMW.
