In 1961, Maserati produced a first series of 9 rear mid-engined cars: The Tipo 63.

The famous "Scuderia Serenissima" of the Volpi count gets two copies, one of which is rearranged by Franco Scaglione and fitted with the V12 of the 250F instead of the 4 Cylinders, after a modest 5th position at the Targa Florio.

The power is 320HP at 8200rpm, which allows a V Max of 312 km / h. But the car is quite unstable and unreliable, despite its design far ahead of its time.

At the beginning of 1962, it adopted the specifications of the Tipo 64 on the chassis, gearbox and engine side, but without the hoped-for success and failed to achieve better results.
