The 1973 Citroën SM, a high-performance coupé produced by the French manufacturer Citroën from 1970 to 1975.
In 1961, Citroën began work on ‘Project S’ — a sports variant of the revolutionary Citroën DS. As was customary for the firm, many running concept vehicles were developed, increasingly complex and upmarket from the DS.
Citroën purchased Maserati in 1968 with the intention of harnessing Maserati’s high-performance engine technology to produce a true Gran Turismo car, combining the sophisticated Citroën suspension with a Maserati V6.
The result was the Citroën SM first shown at the Geneva Motor Show in March 1970. It finally went on sale in France in September of that year. All produced were left-hand-drive, although three official RHD conversions were done in the UK, and recently also Australia.
