AI Overview
The alphanumeric code "ST-SM 1970" most likely refers to the Citroën SM, a high-performance coupé that debuted in 1970. The "ST-SM" could be a typo or an alternative designation for the "SM".
The SM was known for its unconventional design and advanced technology for the time.
Features and significance of the Citroën SM
Engine and speed:
It was powered by a Maserati V6 engine, a product of Citroën's purchase of the Italian car company in 1968.
The SM was the fastest front-wheel-drive car in the world at its launch, with a top speed exceeding 220 km/h (137 mph).
Innovative technology:
It inherited the revolutionary hydropneumatic self-leveling suspension system from the Citroën DS.
Other unique features included variable-assist power steering (DIRAVI), swiveling directional headlights, and powerful all-around disc brakes.
Design:
Designed by Robert Opron, the SM had a sleek, aerodynamic, and futuristic look.
Its exterior was characterized by a distinctive teardrop shape, a wide front track that narrowed at the rear, and covered headlights.
Legacy:
The SM was short-lived, with production ending in 1975 following Citroën's bankruptcy and takeover by Peugeot.
Despite its unreliability and high maintenance costs, the SM was highly influential and is considered a cult classic for its innovation.
