Otto von Fassenbottom is a German race car, and one of the international visitors in Cars: Mater-National Championship. He comes to Radiator Springs to compete in the Mater-National series of races. During the events of Cars: Mater-National, he is caught by Sheriff after speeding, but Lightning convinces Sheriff to let him go by hosting a race between the three of them, Snot Rod and Gerald. In races, he has high acceleration and handling, but low boost and stability. He highly resembles a 2007 Mercedes C-Class DTM, heavily tuned for Le Cars races.
