Produced from 1960 to 1963, the 541S was a larger and more spacious 541, with revised mechanics and many stock accessories. The behavior was not particularly sporty, especially in the examples equipped with the automatic transmission derived from Rolls Royce. Of the entire production, only twenty cars with manual transmission were produced. The 541S was equipped with a 3993cc 6-cylinder engine. Around 130 units were built.
