The car developed from the cooperation with the company Maserati, taken over in 1968. The engine came from there and is actually an eight-cylinder decimated by two cylinders. This was not without problems for the firing intervals, if it would remain at 90į cylinder angle and two connecting rods on a crank pin. Whether therefore the somewhat harsh sound?

The SM was otherwise one of the most elaborate projects of the time. A sports car company supplied the 4-camshaft engine for a limousine, which had already innately a very cleverly devised chassis. Sporty engine came into comfortable and in total not lightweight body. CitroŽn thereby took up the pre-war time with Bugatti, Delage, Delahaye, Voisin and others. It should be the fastest front-wheel drive and the only French six-cylinder of its time



The difficulties to keep running that all without repair, one can only guess. After all, this was once again a typical CitroŽn product, which enthused and made you despair. And in addition an engine necessarily dependent on regular maintenance.

It took courage to bring out a top-class model with two doors and a large hatchback. After all, it was fairly streamlined, e.g. by a fully (glass) cased front and largely covered tyres, which the aerodynamics engineers had always dreamed of. Helpful is here the flat, behind the front axle mounted engine.

The car had enough technical goodies on board. Today the speed-controlled power steering is no problem, but here the control had to be handled with a governor due to lack of electronics. The cornering light was, after all operated hydraulically. Many wonderful details that made driving with this car to an experience. Have a look what the US regulatory authorities have done at the front.



If it really drove and not devoured huge running costs. Obviously, the timing chains made problems, if they have not adjusted in time. That was difficult between the engine and bulkhead. From a shaft relatively near the top in the V were driven each the two camshafts of one cylinder bank. And this included a tensioning pinion. The exchange of even only one of the chains was not possible without engine and transmission disassembly.



Here you can see the SM as a convertible. There were only very few of it, so complicated and costly was the change. Figure 1 shows even one of the two state limousines.



This SM was successfully returned from a Paris-Beijing Tour. Perhaps the SM was tested even more at the Rallye du Maroc, which was finished victorious with the drivers Jean Deschazeaux and Jean Plassard in 1971.



Here still a redesigned SM from modern times by the French tuning company Parotech. Then one knows only really to appreciate the former, classically beautiful form. It was one of the last great deeds of the company CitroŽn. Even at the time of the SM, Fiat had bought into Citroen with 15 percent and the company was no longer independent under the umbrella of the PSA since 1976. This happened together with the production stop of the SM after the production of about 12,000 units, 2,000 exported to USA. 05/15
