90°
PRV V-ANGLE
In the mid-size saloon, the Safrane's 3.0-litre Z7X takes code 760 — phase 1 only. It is the most frequent confusion in the whole family: the 24-valve phase 2 Laguna gets the 60° L7X, which is not a PRV.
Six cylinders in a 90° V, transverse, 2,963 cc, 9.6 compression ratio: the 1993 Pub et Trade workshop sheet gives 125 kW (170 bhp) at 5,500 rpm and 24.5 daNm at 4,500 — one daNm more than the Safrane, on the same engine. Closed-loop, catalysed Siemens multipoint injection, 55-way S 103 715 100 ECU housed behind the right headlamp, PK1 gearbox or AD8 automatic. The rest of the family is on the Z7X file.
From mid-1997 on the Laguna — and only April 1999 on the Safrane — the 60° « PR » V6, L7X at Renault and ES9 at Peugeot, replaced the PRV. It is a completely different, 24-valve engine, and only the PRV versions belong on this site. The Laguna kept the choice between manual and automatic with the L7X, while the Safrane lost its manual.
The full table of Z7X variants — from the 150 bhp American versions to the 268 bhp Safrane Biturbo — is on the Z7X file; PSA's 24-valve, for its part, is the ZPJ4.
That is how the Library presents the Z7X 760 sheet: the last production PRV V6 Renault, six cylinders in a 90° V mounted transversely. The last Douvrin V6 left the line on 15 June 1998, after 970,315 units; the phase 1 Laguna had left the PRV a year earlier.
Around 1995, Hartge built a Laguna Biturbo prototype on the same block: the twin-turbo 3.0 L PRV taken to 280 bhp in a much lighter front-wheel-drive car, 0-100 km/h in about 7 seconds. Burned by the Safrane Biturbo's flop, Renault refused production — about five to seven cars were built. The story is in the Journal article « Safrane Biturbo — the German rival, prepared in Germany ».
On cars fitted with the PRV V6, the engine mounts are not hydraulic. The dome-shaped hydraulic mount with its fluid section that turns up among « Laguna 1 » parts belongs to the G8T diesel Laguna — not to the V6.
The figures from the 1993 workshop sheet (REN-75D), six pages readable page by page in the Library — and two answers from the FAQ.
The Laguna sheet, and — for the same Z7X — the phase 1 Safrane sheet and manual: Laguna V6 (Z7X-760) — 1993 Pub et Trade sheet · Safrane RT/RXE V6 (Z7X-722/723) — Pub et Trade sheet · M.R.302 Safrane — engine and fuel system
The Laguna has its own section on the forum — presentations, restorations, questions to members who drive one. Renault Laguna section →
The Safrane and the Espace close the chapter with her — and the Z7X has its file, from 150 to 268 bhp.
