Strong off its success with the Citroen DS, which would continue uninterrupted for another, Citroen entered into a joint venture with Maserati to produce the Citroen SM, which was made between 1970 and 1975.
To put it simply, this car had only advantages and qualities, except one, which proved to be its undoing: its gas consumption. 18 miles a gallon would simply not cut it in 1970s France and Europe as a whole.
The Citroen SM relied on the famous hydro-pneumatic suspension of its famous forebear, the DS, which was decades ahead of its time when introduced in 1955. It also had a powerful, 170 or 180 horsepower V6 engine of 2.8 or 3 liter displacement, and a precise five-speed manual transmission. Later models were available with a three-speed automatic gearbox.
The elongated, elegant styling and the inspired performance of this grande routière initially garnered many sales, but the economic reality quickly caught up, and the model was discontinued in 1975, with over 13,000 cars produced.
