PEUGEOT MODELS
From the carburetted 504 Coupé to the fuel-injected 605, the lion's PRVs wore their own codes — a family that also slipped under the bonnets of the Lancia Thema and, most famously, the DeLorean DMC-12.
Peugeot fitted the Douvrin V6 across four generations of flagships: the 504 Coupé & Cabriolet and the 604 opened the account among the very first PRV cars, the 505 and then the 605 carried it into the 1990s. Each evolution wore a new code — ZM and ZMS on carburettors, ZMJ, ZNJ and ZN3J on injection, ZPJ on the 605 era shared with the Citroën XM.
The most famous of the family never wore a lion: the ZMJ-159, a 130 bhp 2.8, powers the DeLorean DMC-12 of Back to the Future.
The 24-valve summit of the PSA line — the 200 bhp ZPJ4 with its ACAV variable intake, pushed to 408 bhp by EIA for the Venturi 400 GT — has its own file: ZPJ4.
The 504, 604 and 505 have their own file — and so does the 605/XM pair.
