The Peugeot 504 is a mid-size, front-engine, rear wheel drive automobile manufactured and marketed by Peugeot from 1968-1983 over a single generation, primarily in four-door sedan and wagon configurations – but also as twin two-door coupé and convertible configurations as well as pickup truck variants.

The sedan/berline was styled by Aldo Brovarone of Pininfarina, and the coupé and convertible twins were styled by Franco Martinengo at Pinifarina, with sketches produced in-house at Peugeot.

The 504 was noted for its robust body structure, long suspension travel, and torque tube drive shaft – enclosed in a rigid tube attached at each end to the gearbox housing and differential casing, relieving drive train torque reactions. The 504 ultimately achieved widespread popularity in far-flung rough-terrain countries – including Brazil, Argentina, Australia, Ivory Coast, Ghana, Cameroon, Benin, Kenya and Nigeria.[6]

More than three million 504s were manufactured in its European production, with production continuing globally under various licensing arrangements – including 27,000 assembled in Kenya[7] and 425,000 assembled in Nigeria, using knock-down kits – with production extending into 2006.[8][6]

Having debuted as Peugeot's flagship at the 1968 Paris Salon, the 504 received the 1969 European Car of the Year. In 2013, the Los Angeles Times called it "Africa's workhorse.
