The 402 was characterized by what became during the 1930s a "typically Peugeot" front end, with headlights well set back behind the grille. The style of the body was directly modelled on the
Chrysler Airflow, which was seen as revolutionary at the time. Peugeot bought one or two Airflows to disassemble and study. Thus, the 402 received the
soubriquet:'' 'Fuseau Sochaux' ''in France – this loosely translates to the "
spindle or axis of Peugeot's
main plant in Sochaux".
Streamlining was a feature of French car design in the 1930s, as can be seen by comparing the
Citroën Traction Avant or some of the
Bugattis of the period, such as the
Type 57, with predecessor models such as the
Citroën Rosalie. Peugeot was among the first volume manufacturers to apply streamlining to the extent exemplified by the 402 and smaller
Peugeot 202 in a volume market vehicle range. Recessed ‘safety’ door handles also highlighted the car's innovative aspirations, as did the advertised automatic transmission and diesel engine options. Comparisons with Citroën's large family car of the time, the
Traction Avant were and remain unavoidable. In that comparison, the basic underpinnings of the 402 remained conventional, based on known technologies, and presumably were relatively inexpensive to develop and manufacture: it was
Citroën that in 1934 had been forced to sell its car manufacturing business to its largest creditor,
Michelin. Sticking to a traditional separate chassis configuration also made it much easier for Peugeot's 402 to be offered with a wide range of different bodies. The amount invested in developing the car and in tooling up to produce it, as well as the aggressive way in which it was priced, suggest that Peugeot always intended the 402 to be a big seller by the standards of the time. Nevertheless, it was also a big car at the high end of the volume car market, and in advertising material of the time Peugeot evidently thought it important to highlight one or two tempting standard features, such as the twin windscreen wipers powered by their own electric motor, the semaphore-style
trafficators, the clock included on the instrument panel, the twin sun visors and the switchable reserve section of the fuel tank. ==The range==
