No production figures recorded yet.
History
The 450S was an evolution of the 300S chassis, fitted with a new V8. At 4.7 litres it was the largest engine Maserati had produced up to that time, and it was the company's most powerful sports car of its period.
In 1957 the 450S won the Sebring 12 Hours with Fangio and Behra. Of the ten cars built, seven were sent to the United States.
