sm architecture

CONFORT, PERFORMANCE AND SAFETY are the three key words Citroën used to describe the SM at it's launch at the Geneva Motor Show in 1970. The SM brings together and harmonizes a set of solutions which make it an outstanding car and a landmark in the history of the automobile. It's advanced streamlining, the safety and comfort of its hydropneumatic suspension and of its assisted return steering together with its balanced architecture give it exceptional active safety qualities. Its very complete and refined equipment, its extreme comfort under all circumstances, on any road and at any speed are seldom simultaneously found on cars capable of high performance. The Citroën SM is neither a sports car nor a luxury limousine, nor yet a prototype for tomorrow's road safety. It welds these three concepts reaching the highest levels of safety, comfort and performance.

The structure of the SM closely resembles that of the DS: a steel monocoque on a rigid steel platform with detachable front steel wings and aluminum front hood. The rear wings are an integral part of the structure and cannot be unbolted like those of the DS.
BODY: 4-seater 2-door coupe. Integrated body on rigid platform. Streamlined body with forward fairing. and air intake for engine and disc-brake cooling. Shock proof plastic fuel tank placed under the boot. between the rear wheels. Headlights and front number-plates under transparent protection across the entire width of the vehicle. Triplex (sandwich-glass) windscreen. Electric- power driven curved side windows completely retractable into the doors. Pivoting. entirely adjustable back-seat side windows.
