Following its launch at the 1970 Geneva Show, the SM was praised for its power and its chassis, with its road holding benefiting from the engine’s positioning behind the front axle line.
In 1972 the carburettors were replaced by Bosch fuel injection, raising output to 178bhp at 6,250rpm and 172lb.ft at 4,000rpm; the following year its engine capacity was increased to 2,965cc – using the same V6 that was to power Maserati’s new Merak – with its output rising again to 190bhp at 5,750rpm and 181lb.ft at 4,000rpm although performance remained much the same to the original car. It was at this time that automatic transmission became optional.
The expensive SM, however, proved something of an anomaly: too fast for Citroen’s traditional customers but too quirky for traditional Maserati owners. As a result, when production ceased in 1975, only 12,024 had been built and this fastest and most striking of all Citroens is now very collectable.
The SM on offer today is a lovely unadulterated example of the Citroen-Maserati partnership. Complete with full English paperwork the car presents itself as a strong investment. Maintaining its original charm, poise and quirkiness and is bound to be a head-turner wherever it goes and with the Maserati V6 in full song it is a sound to behold. This car presents itself as great investment which can be driven with gusto on the open road.
