About this vehicle
The 1980 Peugeot 505 represents a significant era in Peugeot’s history, serving as the manufacturer’s final rear-wheel drive model. Produced primarily in Sochaux, France, the 505 was designed as a large family car and enjoyed a long production lifespan spanning from 1979 to 1992.
This specific vehicle features the 2.3L XD2 diesel engine, which belongs to a lineage of Peugeot diesels known for their durability in various global markets, including significant production runs in Argentina, China, Thailand, Indonesia, and Nigeria. While this model is commonly associated with robust mechanical reliability, owners often research the transition between different engine families, noting that later models moved toward XUD diesel engines.
Maintenance for these vehicles typically focuses on the longevity of the mechanical fuel injection systems and managing the cooling requirements of the large-displacement diesel engine. Because this is a rear-wheel drive vehicle from the late 70s/early 80s era, regular inspection of suspension components and drivetrain seals is a common practice among owners. Technical details regarding exact engine output should be verified through a dedicated service manual.
