in 1962 and 1963. In 1964 the Series II was introduced, which had a different body. Three such cars were made, and four older Series I cars were given a Series II body. It brought the total number of GTOs produced to 36. In 2004, Sports Car International placed the 250 GTO eighth on a list of Top Sports Cars of the 1960s, and nominated it the top sports car of all time. Motor Trend Classic placed it first on a list of the "Greatest Ferraris of all time". 250 P The 250 P was a prototype racer produced in 1963, winning that year's 12 Hours of Sebring, 1000 km Nürburgring and the 24 Hours of Le Mans. The 250 P used an engine derived from the 250 Testa Rossa, mounted in a rear mid-engine, rear wheel drive configuration. 250 LM The mid-engined 250 Le Mans looked very much the prototype racer but was intended for production as a road-going GT. Descended from the 250 P, the Le Mans also appeared in 1963 and sported Pininfarina bodywork. Ferrari was unable to persuade the FIA that he would build the 100 examples required to homologate the car for GT racing. Eventually, 32 LMs were built up to 1965. As a result, Ferrari withdrew from factory participation in the GT class of the 1965 World Sportscar Championship, allowing the Shelby Cobra team to dominate. A 250LM, competing in the Prototype category, won the 1965 24 Hours of Le Mans. Only the very early LM's were true 250 models. All the others were made as 3.3-litre models, and as such should have been named 275 LM. The early cars were converted to the 3.3-litre engine. GT cars The 250 design was successful both on the road and on the track. A number of GT models were built in varying states of road or racing trim. 250 Europa The 250 Europa, introduced at the 1953 Paris Motor Show, was the only one of the family to use a different engine, sporting the 2963 cc Lampredi V12 based on a design for Formula One 3.3 L engine. It was a square engine, with of bore and stroke, developing at 6,300 rpm, with three Weber 36DCF (or DCZ) carburettors, and mated to a 4-speed transmission. With the long wheelbase and Ferrari 375 America-style bodies, it was designed as a grand tourer. Three different rear axle ratios
