After a few dozen of 410 Superamericas produced from 1957, this 400 took over at the end of 1959. But its V12 has nothing to do with the previous one, since it is based on the Colombo block, increased to 4-litre and 340 hp, which was not the case of the 410. Out of the 47 units of 400 Superamericas produced, six received this cabriolet bodywork designed by Pininfarina.
