1957 Maserati 450S

Built to contest the 1957 World Sportscar Championship, the 450 S was the biggest threat to Jaguar, Ferrari and Aston Martin. At the forefront of its competitor’s minds was the awesome 400 bhp V8.

Maserati had repeated success with the 3-litre 300S, when they decided to take advantage of the displacement limits. Engineer Guilo Alfieri decided to depart from the inline-6 and instead turn to a V8 by the fact that it would “have to reach certain power limits and possess indispensable harmony among stress levels and thermal loads of consumption.”

Motivated by Tony Parravano and need for an engine that could contest Indianapolis, the V8 was first tested in a car in late 1956. With a quad cam, twin spark V12 power was an impressive 390 bhp or 400 bhp on a good day. This left Ferrari scrambling to come up with a competent alternative.

This engine was fitted into a modified 300/350S chassis with inadequate braking for the V8’s power. None-the-less factory driver Juan Manuel Fangio out accelerated the competition and could win if the car kept running.

Maserati entered the 450 in all seven races for the World Sportscar Championship. In the end, it was a dead tie between Ferrari and Maserati at the final round, and Ferrari took the cake once almost all the Masers dropped out.

The 450S only achieved two notable victories at the 12-Hours of Sebring and Swedish GP in 1957. Many times it failed but not due to engine failure. At the same time Maserati was actively involved in F1, giving Fangio his fifth Driver’s Championship so many resources and time were diverted from the 450 to the legendary 250F.

Stirling Moss convinced Maserati to build a special Coupe for LeMans using plans by Frank Costin. The body was finished by Zagato and painted bright red. During the 24 Hours, the Maserati suffered from overheating problems and retired with a broken drive shaft. It was later converted into a road car by Maserati

After 1957 Maserati decided to retire from racing all together, leaving the 450S as their last great sports racing car. Many of the 10 cars produced made their way to America, and won even more events driven by Carroll Shelby, Jim Hall, and Temple Buell.
