1966 Citroen DS 21

Such a stunning creation as the DS deserved better engines than those which had been used in the Traction Avant before the war and, from 1965, it started to get them. In that year, the Citroën DS21 was launched with a 2175cc engine of 109bhp. After the very successful restyle of the vehicle in 1967 – with swivelling headlamps and a shark-like nose – the DS19 was replaced by the DS20 (1985cc and 90bhp). But it was in the 1970s that the Goddess reached its ultimate genesis, with a 2347cc unit dropped in to create the DS23. In fuel injected form, this pumped out 141bhp. At last the performance matched the appearance.
