The Maserati Quattroporte () is a four-door full-size luxury sports sedan produced by Italian automobile manufacturer Maserati. The name translated from Italian means "four doors". The car is currently in its sixth generation, with the first generation introduced in 1963. Quattroporte I (AM107, 1963–1969) The original Maserati Quattroporte (Tipo AM107) was built between 1963 and 1969. It was a large saloon powered by V8 engines—both firsts for a series production Maserati automobile. History The task of styling the Quattroporte was given to Turinese coachbuilder Pietro Frua, who drew inspiration from a special 5000 GT (chassis number 103.060) which he had designed in 1962 for Prince Karim Aga Khan. While the design was by Frua, body construction was carried out by Vignale. Series I (1963–1966) The Quattroporte was introduced at the October–November 1963 Turin Motor Show, where a pre-production prototype was on the Maserati stand next to the Mistral coupé. Regular production began in 1964. The Tipo 107 Quattroporte joined two other grand tourers, the Facel Vega and the Lagonda Rapide, capable of traveling at speeds of up to on the new motorways in Europe. It was equipped with a 4.1-litre () V8 engine, rated at DIN at 5,000 rpm, and equipped with either a five-speed ZF manual transmission or a three-speed Borg Warner automatic on request. Maserati claimed a top speed of . The car was also exported to the United States, where federal regulations mandated twin round headlamps in place of the single rectangular ones found on European models. Maserati manufactured 230 of its first generation Quattroportes Between 1963 and 1966. Series II (1966–1969) In 1966, Maserati revised the Tipo 107, adding the twin headlights already used on the U.S. model. A leaf-sprung solid axle took the place of the previous De Dion tube. The interior was completely redesigned, including the dashboard which now had a full width wood-trimmed fascia. In 1968 alongside the 4.1-litre a 4.7-litre version became also available (AM107/4700), developing DIN. Top speed increased to a claimed , making the Quattroporte 4700 the fastest four-door sedan in the world at the time. Around 500 of the second series were made, for a total of 776 Tipo 107 Quattroportes. Production ended in 1969. Specifications The first generation of the Quattroporte had a steel unibody structure, complemented by a front subframe. Front suspension was independent, with coil springs and hydraulic dampers.
