Maserati Tipo 61
The Maserati Tipo 60/61 is a racing car that Officine Alfieri Maserati SpA built for customers in Modena from 1959 to 1961. There was no factory assignment at racing events because of the tense economic situation of the company at the time. 22 vehicles were produced.
construction
The car became known as the Maserati “Birdcage” (“bird cage”), an allusion to the unusual, only 30 kg heavy tubular space frame by Giulio Alfieri, which consists of more than 200 relatively thin-walled steel tubes with a small diameter. With this construction, Maserati achieved a strength similar to that of a much more expensive monocoque. A special feature of this Maserati frame is that it shows the shape of the vehicle even without a body.
The bonnet of the "Birdcage" is extremely flat despite the front engine; because the in-line four-cylinder is installed at an angle of 45 degrees so that the air flow is favorable, also because of the tightly enclosed front wheels and the spoiler lip at the rear.
The wheels (wire-spoke wheels) are suspended at the front on double triangular wishbones with coil springs and telescopic shock absorbers, a De-Dion axle with transverse leaf springs and telescopic shock absorbers is installed at the rear . The car has disc brakes on all four wheels (made by Maserati according to Girling's plans).
The body was made by hand by the supplier Allegretti e Gentilini .
In 1961 the successor Maserati Tipo 63 was also built according to the birdcage principle, but with a mid-engine.
