After 6 years of production (1969-1975) only 12,920
SM’s had been built, and unsurprisingly, there was no
replacement. Citroen was never one to follow
conventional wisdom. The SM incorporates Citroen’s
hydra-pneumatic suspension, inboard front disc brakes,
front-wheel drive, swivel headlamps, and an odd power
steering set up that required drivers to re-think their
steering input choices.
The Maserati derived 2.7 liter 60 degree V6 was an
engineering marvel, though prone to timing chain
problems. The top speed was reported to be 137 mph.
