The blue Citroën SM from 1971 with Maserati motor (V6), 178 HP, 225 km/h
The Citroën SM is a high-performance coupé produced by the French manufacturer Citroën from 1970 to 1975. The SM placed third in the 1971 European Car of the Year contest, trailing its stablemate Citroën GS, and won the 1972 Motor Trend Car of the Year award in the U.S.
The SM did not find a sufficient customer base in the small European GT market, but much of the SM’s technology was carried forward to the successful Citroën CX, launched in 1974 the DIRAVI steering being the most obvious example.
The same basic engine in enlarged 3.0 L form (some in Italy had 2.0 L) was used in Maserati’s own Merak (1,800 units) and later with some modification in the Biturbo (40,000 units).
The Merak, Khamsin, and Bora, used Citroën’s high-pressure hydraulics for some functions, and the Citroën gearbox in the Merak, during the Citroën-Maserati alliance.
