It was Renault's need for an engine for its new flagship — the R30 — that accelerated the PRV's development. At Douvrin the lines went up in summer 1973 and everything was running by January 1974: the first Renault with a V6 was on its way.
The R30 opened with the 2,664 cc Z6V on carburettors — 131 bhp. The 30 TX then adopted K-Jetronic injection with the Z7V, at 144 bhp, an engine it shared with the early Renault 25.
Every naturally-aspirated Renault code — Z6V, Z7V, Z7W and the Alpine variants — is detailed in the Renault codes file.
Before the end of 1975, at least five different PRV models were on sale — the alliance's V6 spread fast, and the R30 carried Renault's colours.
The R25 took over with the Z7V then the Z7W — before making history in 1985 as the first car with a turbocharged PRV: the R25 V6 Turbo.
Safrane, Laguna and Espace closed Renault's PRV chapter in the 1990s — see their file.
