1972 Citroen Sm

Citroen SM

The Citroën SM was a gamey operation putsché produced by the French producer Citroën ‘tween 1970 and 1975. The SM located one-third in the 1971 European Car of the Class competition, tracking its stablemate Citroën GS, and won the 1972 Motive Drift Car of the Yr laurels in the US in 1972.

In 1961, Citroën began work ‘Externalise S’ – a sports variance of the subverter Citroën DS. As was habitual for the tauten, many functional construct vehicles were highly-developed, progressively composite and upmarket from the DS – finally decorous a glory fomite for the blade. Citroën purchased Maserati in 1968 with the design of harnessing Maserati’s gamy execution locomotive engineering to get a truthful Granny Turismo car, combination the advanced Citroën hiatus with a Maserati V6 locomotive.

The solution was the Citroën SM (Athletics Maserati), commencement shown at the Hollands Drive Display in March1970. It last went on sale in France in September of that twelvemonth. All produced were left-hand-drive, although approximately RHD conversions were through in the UK.

The SM was Citroën’s flagship fomite, competing with otc gamy operation GTs of the clock from manufacturers such as Panther, Lotus and Porsche. It was too Citroën’s way of demonstrating equitable how lots powerfulness and execution could be accommodated in a front-wheel crusade conception.

The SM innovated a new typewrite of varying attend index direction that has since gap passim the fomite universe. It allowed heavy assist to the automobilist spell parking, but fiddling assist at throughway speeds. The direction really had the like “aid” at all speeds – the guidance was hydraulicly locked against guidance motility of the wheels from the route (“feedback”) capable the capacitance of the whole. Striking a pothole at heights upper would not play the wheel in the driver’s custody! The hydraulic insistency to the ability snap whole increased with upper, gift the printing of less and less ability “attend.” Decent coerce was admitted to the focusing whole to restitution the wheels to the neat forwards post when the car was not moving. The direction imperativeness was regulated by a flyweight motor regulator compulsive by the shackle (junior-grade) calamus of the manual gearbox and by a proportioning valve attached to the force in the automatonlike gearbox, which pressing was relative to the amphetamine of the production calamus.

Contemporaneous self-propelling journalists were about gushy most the SM’s active qualities, which were different anything they had experient anterior. The SM provided a combining of puff, shrewd manipulation, and highschool execution not uncommitted in any over-the-counter car at the metre. Democratic Skill celebrated that the SM had the shortest fillet outstrip of any car they had time-tested. To this day this fillet outdistance stiff great.

Unluckily, the SM did not get a sufficient client foot in the European GT commercialize, but often of the SM’s engineering was carried advancing to the successful Citroën CX, launched in 1974 – the DIRAVI guidance organism the almost obvious exemplar. The like canonic locomotive in blown-up 3.0 L configuration (roughly in Italy had 2 liter) was put-upon in Maserati’s own Merak which, jointly the Khamsin, put-upon Citroën’s highschool insistency hydraulics.

Styling

The flavor of the car was rather trenchant. Intentional in-house by Citroën’s head architect Robert Opron, the SM eagre a faint kinfolk resemblance to the DS. Seen from supra, the SM resembled a tear, with a often wider raceway at the strawman.

The SM was outstandingly streamlined for its era, with a selfsame low puff coefficient. European critics marvelled at the resulting power to travelling for hours at 200 km/h (120 mph) in puff. In gain, many of the details reflected Robert Opron’s American scope, notably the shortened ‘fins’ at the back.

The SM combined many strange features – lights that swivelled with the guidance (omit in the USA where such was illegal), unequaled self-centering and full powered guidance, self-leveling headlights (exclude in the USA where such was illegal), a wiper mechanics that was ‘medium’ to rainfall, and many over-the-counter features that are now humdrum on the cars of nowadays.

The SM’s invention was dateless; the car was level ill-used in a 1999 telly advertizement for British Oil of Spain, where ‘a futurist car was needed’. It situated 11th on Machine Cartridge’s 2005 “100 Coolest Cars” itemisation.

In 1970, it was a car of the hereafter and the quickest front-wheel crusade car to be made. It was an lesson of the car as a symbolisation of optimism and liberal engineering, like to the SM’s contemporaneous, the Concorde aircraft.

US exports

The primary exportation commercialize for the SM was the Joined States. In the US, the mart for personal sumptuousness cars was practically bigger than in Europe, with competitors care the Cadillac Eldorado, Lincoln Crisscross IV and Fording Thunderbird aboard a great pick of Italian, English, and German imports. However, the unequaled innovation of the SM made quite plash and won the Motive Course clip Car of the Class prize in 1972: unheard of for a non-US fomite at the clock.

The SM’s six headlamp arrange was illegal in the Joined States and accordingly, US stipulation cars were fitted with quatern set beat open lamps.

Scorn initial achiever, US sales ceased dead – Citroën expected (but did not invite) an immunity for the 1974 modelling yr 5 mph bumper regulating imposed by the NHTSA. The entire varying acme respite of the SM made compliancy unsufferable. The law as scripted called for bumpers to be an claim peak off the earth at all multiplication, yet according to the laws of physics, cars dip at the nuzzle on braking. Vehicles classified as trucks were e’er free and the stallion law was finally repealed in 1981. The net deal of 134 now illegal 1974 US modelling SMs were shipped to Japan.

Engines

The SM was sold with tercet real like, minor, jackanapes engines, all derived from the modern-day Maserati V8 fitted to the Quattroporte. Because of the V8 ancestry, this locomotive sported an strange 90 point lean ‘tween cylinder banks – a trait divided with the PRV V6.

The engines – invariably mounted butt the breast axle were:

  • 2.7 L V6 with Wb 42 DCNF carburettors, “C114-1” (170 bhp) (1970-1972)
  • 2.7 L V6 with Bosch D-Jetronic injectant, “C114-03” (178 bhp) (1973-1975 – Not useable in the US)
  • 3.0 L V6 with Wb 42 DCNF carburettors, “C114-11” (180 bhp) (1973-1975 – US lonesome in 1973, relaxation of the mankind, reflex alone in 1974 & 1975)
  • The sizing of the 2.7 L locomotive was circumscribed by French puissance fiscale revenue, which efficaciously prohibited enceinte translation vehicles. The locomotive was too victimised in the Maserati Merak from 1973 to 1982 and the Ligier JS2 sports car. The net SMs were produced in the Ligier mill in Vichy.

    5 amphetamine manual and 3 velocity Borg Warner full reflexive transmissions were fitted, but with the residue of the mankind away Northerly America alone acquiring the full robotlike in 1974 & 1975.

    The C114 is a comparatively inflexible whole, provided sure modifications are performed to pass watery points lead to ruinous price:

  • The na filled beat valves may gaolbreak and fall into the cylinder. Upstanding valves are uncommitted.
  • Main dispersion range may wear untimely due to undue shaking. A curving strand clipper should be fitted, eliminating quivering.
  • Oil ticker cause lance is underdimensioned and may breakage. Maserati beefed up the lance in after versions, and this should be retrofitted ie already nowadays.
