Our more cosmopolitan readers are no doubt aware that “S/M” can be shorthand for sadomasochism (the enjoyment of inflicting and receiving pain). That alternate meaning makes the designation of the Citroen SM all the more piquant, for although the goal of this ne plus ultra of Citroens was high-speed comfort, its design was every bit as adventuresome (and as kinky) as the name implies. And, as we’ll see, it also involved more than a little pain for everyone involved.
The word “new” is much abused in the automotive business. If you believe the ad writers and press releases, cars are all-new almost every fall, but the reality is that most cars are the product of a gradual evolution stretching back decades. Well into the 1960s, there was little on the average car that would seriously puzzle a mechanic from before World War I. Every so often, though, an automaker takes the plunge on a design that really breaks the mold, a car like the Mini, the Corvair, or this one: the startling 1955-1975 Citroen DS.
If you make a list of the most noteworthy, technically innovative, and memorable cars of the 20th Century, many of them have one thing in common: the twin-chevron emblem of Automobiles Citroën SA. Founded by an inveterate gambler, Citroën developed a reputation for bold engineering that beggared almost every other automaker in the world, building cars that were decades ahead of their time. Let’s look at the first great Citroën, the car known in France as “La Reine de la Route” (queen of the road): the 1934-1957 Citroen Traction Avant.
