1972 Citroen Sm Presidential
Citroen SM Presidential
The Citroën SM was a gamy execution takeoveré produced by the French producer Citroën betwixt 1970 and 1975. The SM located thirdly in the 1971 European Car of the Twelvemonth competition, tracking its stablemate Citroën GS, and won the 1972 Motive Drift Car of the Class accolade in the US in 1972.
In 1961, Citroën began process ‘Externalise S’ – a sports version of the subverter Citroën DS. As was wonted for the fast, many working conception vehicles were highly-developed, progressively composite and upmarket from the DS – finally comely a nimbus fomite for the blade. Citroën purchased Maserati in 1968 with the aim of harnessing Maserati’s gamey operation locomotive engineering to farm a straight Granny Turismo car, compounding the advanced Citroën reprieve with a Maserati V6 locomotive.
The resolution was the Citroën SM (Mutant Maserati), beginning shown at the Hollands Motive Prove in March1970. It last went on sale in France in September of that twelvemonth. All produced were left-hand-drive, although around RHD conversions were through in the UK.
The SM was Citroën’s flagship fomite, competing with former highschool functioning GTs of the metre from manufacturers such as Panther, Lotus and Porsche. It was likewise Citroën’s way of demonstrating equitable how often might and operation could be accommodated in a front-wheel campaign invention.
The SM innovated a new typewrite of varying aid mightiness guidance that has since bedcover end-to-end the fomite universe. It allowed expectant aid to the automobilist spell parking, but piddling aid at superhighway speeds. The direction really had the like “aid” at all speeds – the guidance was hydraulicly locked against direction crusade of the wheels from the route (“feedback”) capable the content of the whole. Hit a pothole at mellow swiftness would not turning the wheel in the driver’s custody! The hydraulic pressing to the superpower focus whole increased with velocity, bounteous the effect of less and less might “assistance.” Adequate force was admitted to the snap whole to restitution the wheels to the neat forrader berth when the car was not moving. The focussing force was regulated by a flyweight motor regulator goaded by the quill (lowly) lance of the manual gearbox and by a proportioning valve machine-accessible to the insistence in the machinelike gearbox, which insistence was relative to the fastness of the outturn cock.

Contemporaneous self-propelling journalists were well-nigh burbly some the SM’s active qualities, which were different anything they had experient anterior. The SM provided a compounding of comfortableness, shrill treatment, and eminent execution not usable in any early car at the clock. Democratic Skill celebrated that the SM had the shortest fillet outdistance of any car they had time-tested. To this day this fillet space clay prominent.
Unluckily, the SM did not receive a sufficient client foot in the European GT grocery, but practically of the SM’s engineering was carried ahead to the successful Citroën CX, launched in 1974 – the DIRAVI guidance beingness the about obvious representative. The like canonic locomotive in blown-up 3.0 L manakin (around in Italy had 2 liter) was put-upon in Maserati’s own Merak which, collectively the Khamsin, victimized Citroën’s highschool force hydraulics.
The expression of the car was rather clear-cut. Intentional in-house by Citroën’s chieftain architect Robert Opron, the SM eager a shadowy kinsfolk resemblance to the DS. Seen from supra, the SM resembled a tear, with a practically wider racetrack at the strawman.
The SM was remarkably flowing for its era, with a really low pull coefficient. European critics marvelled at the resulting power to move for hours at 200 km/h (120 mph) in puff. In plus, many of the details reflected Robert Opron’s American desktop, notably the abbreviated ‘fins’ at the bum.
The SM combined many strange features – lights that swivelled with the direction (exclude in the USA where such was illegal), unequaled self-centering and amply powered steerage, self-leveling headlights (exclude in the USA where such was illegal), a wiper mechanics that was ‘sore’ to rainfall, and many early features that are now humdrum on the cars of tod.
The SM’s figure was dateless; the car was eve victimized in a 1999 video advertising for British Crude of Spain, where ‘a futurist car was requisite’. It set 11th on Auto Cartridge’s 2005 “100 Coolest Cars” itemization.
In 1970, it was a car of the futurity and the quickest front-wheel ride car to be made. It was an lesson of the car as a symbolisation of optimism and liberal engineering, like to the SM’s modern-day, the Concorde aircraft.
The chief exportation commercialize for the SM was the Joined States. In the US, the commercialize for personal lavishness cars was practically bigger than in Europe, with competitors care the Cadillac Eldorado, Lincoln Crisscross IV and Crossing Thunderbird aboard a great extract of Italian, English, and German imports. Notwithstanding, the unparalleled invention of the SM made quite splattering and won the Drive Tendency mag Car of the Class honor in 1972: unheard of for a non-US fomite at the meter.
The SM’s six headlamp set was illegal in the Joined States and accordingly, US spec cars were fitted with quatern frozen troll uncovered lamps.
Contempt initial achiever, US sales ceased abruptly – Citroën expected (but did not experience) an immunity for the 1974 example class 5 mph bumper regularization imposed by the NHTSA. The intact varying meridian hanging of the SM made deference unacceptable. The law as scripted called for bumpers to be an accurate stature off the reason at all multiplication, yet according to the laws of physics, cars dip at the pry on braking. Vehicles classified as trucks were forever excuse and the stallion law was finally repealed in 1981. The last deal of 134 now illegal 1974 US modeling SMs were shipped to Japan.
The SM was sold with leash selfsame interchangeable, modest, whippersnapper engines, all derived from the modern-day Maserati V8 fitted to the Quattroporte. Because of the V8 descent, this locomotive sported an strange 90 arcdegree lean ‘tween cylinder banks – a trait divided with the PRV V6.
The engines – ever mounted bum the movement axle were:
The sizing of the 2.7 L locomotive was special by French puissance fiscale revenue, which efficaciously prohibited prominent deracination vehicles. The locomotive was too exploited in the Maserati Merak from 1973 to 1982 and the Ligier JS2 sports car. The terminal SMs were produced in the Ligier mill in Vichy.
5 swiftness manual and 3 hurrying Borg Warner full reflex transmissions were fitted, but with the relaxation of the humankind remote Northwards America solitary acquiring the full reflex in 1974 & 1975.
The C114 is a comparatively stout whole, provided sure modifications are performed to extinguish washy points star to ruinous wrong:
