The Citroën Traction Avant was an automobile produced by the French manufacturer Citroën. About 760,000 units were manufactured from 1934 to 1957.
The Traction Avant, designed by André Lefèbvre and Flaminio Bertoni in late 1933 / early 1934, was the first front wheel drive car in large scale production. Cord had built front wheel drive vehicles a few years earlier in limited quantities at high prices.
The car introduced the use of an arc-welded monocoque frame, where other cars of the era were based on a frame onto which the body (“coachwork”) was built. Monocoque construction results in a lighter vehicle, and is now used for virtually all car construction, although body-on-frame construction is still suitable for larger vehicles such as trucks.
This method of construction was viewed with great suspicion in many quarters, with doubts about its strength. A type of crash test was developed, taking the form of driving the car off a cliff, to illustrate its great inherent resilience.
The novel design made the car seem very low-slung relative to its contemporaries — the Traction Avant always possessed a unique look, which went from appearing rakish in 1934 to familiar and somewhat old fashioned by 1955.
The suspension was very advanced for the car’s era. The front wheels were independently sprung, using a torsion bar and wishbone suspension arrangement, where most contemporaries used live axle and cart-type leaf spring designs. The rear suspension was a simple steel beam axle and Panhard rod with unequal trailing arms, to allow the two torsion bars to run parallel to each other, across the car’s width.
