In the late 1950s Citroen's Bureau Des Etudes began a design study called Project S (also known as the DS Sport program). Several prototypes based on the DS were produced to explore styling and performance enhancements for a projected grand touring version of the model. Then, when in 1968 Citroen acquired a controlling share in Maserati, it exploited the technical prowess of the prestigious Italian sports car maker to develop a high-output engine for its new front-drive sports coupe. Project S was married to an M (Maserati) engine and the Citroen SM was born.
The SM debuted at the 1970 Geneva Motor Show featuring an elegant body created by Citroen designer Robert Opron, and a 2.7-liter, 170-hp V6 mated to a conventional five-speed box. The 90-degree engine, designed by Maserati's Giulio Alfieri, derived from the company's Indy V8. Creating a six-cylinder engine for the SM was tricky, requiring Alfieri to make the unit fit the tight confines of Citroen's preexisting design and not exceed 2700 cubic centimeters (165 cubic inches) to avoid French taxes on engines above this displacement.
Early SMs were fed by three dual Weber carburetors. Halfway through 1972 Bosch D-jetronic fuel injection became standard on cars like this one, owned by Daniel Kunz of Zurich, Switzerland. Automatic transmissions were also offered (mainly for the American market) and in 1973 the SM's V6 was enlarged to 3.0 liters, a powerplant shared with the Maserati Merak.
Kunz's sharp black 1972 SM is packed with all the innovations these Citroen standouts were known for. SMs featured the ingenious independent hydropneumatic suspension system that originated on the DS. Fluid/gas-filled spheres, connected via an integral piston to linking arms at the corners, absorb shocks marvelously, giving the SM the luxurious ride qualities the DS was renowned for. Discs front and back are linked to the suspension a la the DS, and the hydraulics allow braking effort to be distributed automatically between the SM's wide front end and its svelte rear.
