The Ferrari 250 Testa Rossa, or 250 TR, is a sports racing car built by Ferrari from 1957 to 1961. It was introduced at the end of the 1957 racing season in response to rule changes that enforced a maximum engine displacement of 3 litres for the 24 Hours of Le Mans and World Sports Car Championship races. The 250 TR was closely related to earlier Ferrari sports cars, sharing many key components with other 250 models and the 500 TR.
