The Ferrari 250 is a series of sports cars and grand tourers built by Ferrari from 1952 to 1964. The company's most successful early line, the 250 series includes many variants designed for road use or sports car racing. Notable variants include the Ferrari 250 GTO, which holds the record for the highest price paid at auction, and GT cars such at the 250 GT/E, the first mass produced four seater in Ferrari's history. Most 250 series cars are characterized by their use of a 3.0 L (2,953 cc) Colombo V12 engine designed by Giaoccino Colombo. They were replaced by the Ferrari 275 and 330 series cars.
