The Ultimate Car Collection #38; 1954 Citroen Traction Avant 11CV
The Traction Avant (French for front
wheel drive) was designed by André Lefèbvre and Flaminio Bertoni in
late 1933 / early 1934. While not the first production front wheel
drive car it was the most successful.
Not only was the Traction Avant's drive train innovative, so was its arc-welded monocoque (unitized body). Most other cars of the era were based on a separate frame (chassis) onto which the non-structural body (coachwork) was built. Monocoque construction results in a lighter vehicle, and is now used for virtually all car construction.
