The Peugeot 504 has been a strong presence in African countries since the early 1970s and was actually still produced on that continent until 2005 due to its cheap price and high level of ruggedness.

The 504 coupé V6 model was homologated as a Group 3/4 car on July 1st 1975 and has been a mainstay of African endurance “safari” type events ever since its introduction. It enjoyed so much successes that it was quickly nicknamed “The Queen of Africa”. When the 1982 regulations took effect, per the FISA transition and stability rules, the 504 Coupé V6 was transferred into Group B (homologation #3069).
Peugeot would subsequently also homologate the 504 model in its pickup variant on December 1st 1982 and the four-door TN variant on August 1st 1983. It is notable to mention that Group A & N had a minimum interior space requirement and if that figure wasn’t met the car was automatically transferred into Group B. Although it was massively produced with tens of thousand of units, which would have easily made the Peugeot 504 pickup eligible to be homologated in Group A, this minimum interior space rule can be credited with the forceful Group B homologation.
It is a given that under normal circumstances the low powered 504 would stand no chance against the Group B/12 supercars. However, the new Group B regulations were divided in multiple engine displacement classes and could give the less powerful cars a chance at a class win. As such, contrary to some beliefs, the Group B 504 pickup used the European 1971 cc 4 cylinder petrol engine with performance internals as opposed to the V6 version.
Therefore the car was in the B/11 class for engines under 2000 cc and could favourably compete against similar low powered cars. Another myth is that the Group B 504 pickups were 4WD. In fact, the homologation papers clearly show that they were only rear wheel drive (2WD/RWD) – a system less likely to break down and provide better fuel mileage.
As such, many of the early entry and result sheets of the period badly identified the cars as “V6” since the officials were too accustomed to seeing the 504 in its Coupé V6 variant.
In the Group B era, the World Rally Championship (WRC) calendar included two African endurance venues; the Kenya “Safari” Rally and the Côte d’Ivoire Rally. As such, the humble-appearing 504 pickup would eventually line up alongside the famed Group B supercars.
In its first WRC outing, a 504 pickup finished in 8th place at the 1983 Safari Rally in the hands of Johnny Hellier and John Hope. The same duo would bring the car in 15th place at the 1984 edition. The best ever WRC finish for the 504 pickup would be a 5th position at the 1984 Côte d’Ivoire Rally in the capable hands of David Horsey and David Williamson (albeit there were only 12 entries). However, Horsey and Williamson would win the 1984 African Rally Championship while driving the same car.
Although it is a far cry from the Peugeot 205 T16 supercar, speed and horsepower wasn’t everything when it came to endurance rallies: the 504 is the embodiment of that statement.
