The Ferrari TR, or 250 Testa Rossa, is a race car model built by Ferrari in the 1950s and 60s. These cars dominated their arenas, with variations winning the 24 Hours of Le Mans in 1958, 1960, and 1961. They were closely related to the rest of the Ferrari 250 line, especially the legendary 250 GTO. In all, thirty-four 250 Testa Rossas were built, from 1956 through 1961. The phrase “Testa Rossa” means “red head.” The most well known, the 250TR, was produced from 1957 to 1958; only 2 factory cars and 19 customer cars were built. After the 250 GTO, the 250 Testa Rossa is the second most valuable Ferrari model, often valued at more than US$8,000,000. A 1957 250 Testa Rossa sold on August 20, 2011 for $16,400,000, a new world record auction price for a car when inflation is ignored.
