The Citroën Traction Avant is the world's first mass-produced, semi-monocoque bodied, front-wheel drive car.[citation needed] A range of mostly four-door saloons and executive cars, as well as longer wheelbase "Commerciale", and three row seating "Familiale" models, were produced with four- and six-cylinder engines, by French carmaker Citroën from 1934 to 1957. With some 760,000 units built, the Traction Avants were the first front-wheel drives made in such (six-figure) quantity.
