Maserati had risen to the pinnacle of motorsports during the 1950s, with Juan Manuel Fangio earning his fifth World Championship - at the wheel of a 250F - and the runner-up spot in the World Sportscar Championship with the 450S, both in 1957. The racing success did not ensure financial prosperity and the company's future was in jeopardy as the parent company's financial difficulties eventually forced withdrawal from racing.
A new era began for Maserati in 1957 with the launch of the Touring-bodied 3500 GT, its first road-going model built in significant numbers. The luxury '2+2' employed a tubular chassis frame derived from the company's competition experience and an engine from the 350S sports car unit of 1956. The twin-overhead-camshaft, six-cylinder engine was a close relative of that used in the 250F and developed around 220bhp. The coupe body style rested on a 102.4-inch platform while the spyder used a shorter 98.4-inch wheelbase. Production lasted from 1957 through 1964 with 2,226 examples built during that time with 245 wearing convertible coachwork by Vignale. The lion's share of the coupes was bodied by Touring.
When Maserati set about designing the 3500's replacement during the 1960s, it did so with a new two-door 2+2 coupe called the Sebring and a 2-seat gran turismo called the Mistral. The Sebring was produced from 1962 through 1968 with 593 examples built while Mistral production lasted from 1963 to 1970 with 953 units built. The Sebring rested on a 98.4-inch platform, the same as the 3500 GT Spyder, and the Mistral used a shorter (Tipo 109) 94.5-inch wheelbase. Both were equipped with the 3,485cc double overhead camshaft, twin-spark inline-6 cylinder engine of the predecessor that had earned the 250F cars eight Grand Prix victories between 1954 and 1960 and the F1 World Championship in 1957. The engine used hemispherical combustion chambers fed by a Lucas indirect fuel injection system and developed approximately 235 horsepower at 5,500 RPM. Maserati would later switch to V8 engines for their later production vehicles in response to increasing horsepower output by other manufacturers throughout the industry.
The Mistral was powered by a 3.5-, 3.7-, and 4.0-liter version of the inline-6 with horsepower outputs of 235, 245, and 265 bhp, respectively. Twelve examples of the Spyder received the 3500 engine, 76 with the 3.7 L, and 37 Spyders with the 4.0-liter engine. Early Mistral models used the 3500 engine while the final examples had the larger, 4.0-liter unit. 383 examples received the 3.7-liter engine. A five-speed ZF transmission directed power to the rear wheels and four-wheel solid disc brakes provided the stopping power. The front suspension was independent and the back used a solid axle. The body was formed from aluminum and, from 1967, in steel. Pirelli Cinturato 185VR16 CA67 was initially fitted, then later replaced by 205VR15 tires (CN72) on Borrani wire wheels.
The body was designed by Pietro Frua and built by Maggiora of Turin, featuring a curved rear window serving as a tailgate that was cleverly and discreetly incorporated into the flowing shape of the car, an original concept at the time. Originally called the 'Due Posti' (two seats), it was at the suggestion of Col. Simone, the French Maserati Concessionaire, that the Due Posti should be renamed 'Mistral' after a cold northerly wind of southern France (the first of many Maseratis to be given the name of a wind). The Mistral was first shown in a preview at the Salone Internazionale dell'Automobile di Torino in November 1963 and entered production in 1964.
