1954 Ferrari 375 Plus

After winning the Auto Sport World Championships in 1953, Enzo Ferrari decided to build a small series of spiders that would spearhead the Scuderia's latest assault on the World title. These cars were to be known as the 375 PLUS for which Aurelio Lampredi developed a truly powerful V12 engine of nearly five litres while Pinin Farina took care of the coachwork. The results lived up to all expectations and the car also triumphed at Agadir, Silverstone and Le Mans. However, its most significant victory of all was Umberto Maglioli's at the Carrera Panamericana.

The 375 Plus were factory team cars and were not raced by private entrants before the mid-season of 1954, the chassis was the same as the 375 MM, but the engine was using the crankshaft from the 375 GP car increasing the stroke to 74,5mm and the displacement to 4954,34cc. The compression was raised to 9:21 and the carburetors were changed to 3 46 DCF3 twin choke Webers. The horsepower gain was so small 344 @ 6500 rpm (340 @ 7000 rpm), but the mid-range power and the flexibility were greatly improved.
