The pinnacle of the S series barchetta range is the 450 S, developed by G. Taddeucci for the engine and V. Colotti for the chassis and transmission, under the direction of Giulio Alfieri, in 1956.
The 4.5-liter inline V8 produces 400 hp at 7,200 rpm and can reach 320 km/h!

It entered the legend by winning its first race, the 12 Hours of Sebring, driven by Fangio and Behra, and would go on to accumulate 23 victories in total.

This model is a reproduction of the 450S driven by Moss and Jenkinson, which retired from the 1957 Mille Miglia.
Despite Maserati's withdrawal from competition in 1957, it raced as a private team until 1964.
