Maserati Tipo 61

The Maserati Tipo 60/61 are a series of sports racing cars produced between 1959 and 1961 by Italian automobile manufacturer Maserati for privateers racing in sports car events including the 24 Hours of Le Mans in the 2-litre and 3-litre racing category. It used an intricate tubular space frame chassis, containing about 200 chro-moly steel tubes welded together, arranged triangular formation at high stress areas of the chassis, hence the nickname "Birdcage". This method of construction provided a more rigid and, at the same time, lighter chassis than other racing cars of the time.
