1973 Citroën SM
Created during a period of extraordinary innovation, the Citroën SM emerged as arguably the most technically advanced automobile of its era. Initially it was powered by a 2.7-liter Maserati V-6. For 1973 the SM was powered by a 3.0-liter Maserati V-6, as also used in Maserati’s Merak.
The 180 bhp DOHC V-6 engine featured fuel injection and was positioned far back in the chassis for optimal weight distribution, providing excellent handling characteristics despite the front-wheel-drive configuration. With a top speed approaching 140 mph, it was the fastest front-wheel-drive car of its time.
The SM’s groundbreaking hydro-pneumatic suspension system could be adjusted to match road conditions, delivering a remarkably smooth ride while maintaining impressive handling. This sophisticated car also featured speed-sensitive power steering, self-leveling headlights that turned with the wheels, and aerodynamic bodywork so effective that rain would flow off the windshield at highway speeds.
Available with either a five-speed manual or automatic transmission, the SM featured a 116-inch wheelbase and distinctive styling that still appears futuristic today. Between 1970 and 1972, approximately 12,920 examples were produced, with only about 2,400 delivered to the United States market.
