The Maserati Tipo 151 marked a return to more traditional concepts of car design and used a frame comprising a trellis of both round and oval large tubes, an independent front suspension and a De Dion axle which had many similarities to that used on the Type 64 completed a month or so before. The engine was derived from the 450S with a reduced displacement of just under 4.0 Litres. Giulio Alfieri designed the body shape and refined it using a wind tunnel at Milan University. The body was reminiscent of the Frank Costin designed Zagato bodied 450S, but with an accentuated Kamm tail. The mandatory doors opened halfway up the side due to the longitudinal tubes of the frame and the lateral fuel tanks. At Le Mans in 1962 the Johnny Simone car was in the Maserati France colours of red body with a tri-stripe whilst the Cunningham team cars had a white body with two blue stripes. At race end the Cunningham cars went back to the US.
