Brief History:
Three cars were made to run at Le Mans in 1962 - one for Colonel John Simone and the other two for Briggs Cunningham.  The 151 marked a return to more traditional concepts 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.  The body was reminiscent of the Costin designed Zagato bodied 450S, but with an accentuated Kamm tail.  The mandatory doors opened half way up the side due to the longitudinal tubes of the frame and the lateral fuel tanks.  At Le Mans in 1962 the Simone car 151/1 was in the Maserati France colours of red with a tri-stripe whilst the Cunningham team white with two blue stripes.  At race end the Cunningham cars went back to the US - the Simone car to the factory for revision for 1963 which included the standard production 4941cc motor with single ignition and indirect injection, but now producing 430 bhp and now referred to as 151/2.  The car came back again to the factory in preparation for 1964 when there was a massive change to the frame, the mechanicals and the body.  Now designated 151/3 and jokingly called the 'racing van' the engine was unchanged in size.  For 1965 there was again work on the frame and the body and the displacement of the engine was increased to 5046.8 cc.  The driver Lucky Casner was killed during practice. The engine went on to power the Tipo 65 less than 2 months later.
