An incredibly rare Ferrari racing car which won a string of famous races in the 1950s has been tipped to set a world record by selling for £10 million The Ferrari 375 Plus was among the quickest and most powerful racing cars of its time, notching up victories at Le Mans and Silverstone in 1954 The rare Ferrari 375 Plus waits to set off at Mille Miglia, Italy in 1954 The supercharged red motor, which boasts a 4.9-litre 330bhp V12 engine and a top speed of 175mph, was entrusted to only the best and bravest drivers of the time. Its most famous victory was in the Carrera Pan-Americana road race through Mexico at the hands of Umberto Maglioli. The Italian star drove the 2,000-mile course at an incredible average of 107mph and during one five hour period towards the end of the race he averaged 150mph. After passing through the hands of several collectors it was bought in the 1990s by Ferrari importer Jacques Swaters, a close friend of Enzo Ferrari, who restored it to its former glory. The red motor being driven by Hively at Kansas City in 1955 The infamous motor pictured at the front in the 1954 Le Mans race which it went on to win It is now being sold by Swaters' family following his death three years ago. The car is tipped to fetch 10 million pounds, which if realised would break the world record for a racing Ferrari at auction. Philip Kantor, motoring expert at auctioneers Bonhams, said: 'This is a very special car indeed. It is a works racing car which is rare in itself but on top of that only four racing models and one road version were ever built. This car is the first, and only four still remain. The Ferrari pictured at break-neck speed on the track at Mille Miglia in 1954 'It has participated in some of the world's greatest racing events driven by some of the world's best drivers. Very importantly it has an undisputed chassis number - there is no other car in the world like it and its identity has never been called into question. In the 1990s it was beautifully restored by Jacques Swaters, a close friend of Enzo Ferrari, and it has since taken part in Le Mans Classic twice. It is being sold without reserve and we expect it to fetch at least 10 million pounds which would be a world record for a racing Ferrari at auction. The auction will take place at Goodwood Festival of Speed in Chichester, West Sussex, on June 27.
