Everything people ask about the PRV V6 — origins, architecture, generations, engine codes, the cars that used it — answered in a few factual sentences, sourced from this site.
The PRV V6 is a 90° petrol V6 engine born of the alliance between Peugeot, Renault and Volvo. It was built from 1974 to 1998 at Douvrin, in northern France, by La Française de Mécanique — 970,315 units in total.
Because it descends from an aborted V8: the 3,550 cc 90° V8 developed by Peugeot and Renault for the Renault “Project H” luxury saloon. After the 1973 oil crisis buried the V8, engineers removed two cylinders and kept the 90° architecture — unusual for a V6, whose norm is 60°.
The first generation (1974–1985) has non-offset crankpins and uneven firing, fed by carburettors or mechanical injection. The second generation (1985–1998), introduced with the Renault 25 V6 Turbo, gains offset crankpins for smooth running, electronic injection and, from 1990, 24-valve heads. R25 V6 Turbo file →
Five displacements: 2,458 cc (turbo), 2,664 cc, 2,849 cc, 2,963 cc and 2,975 cc — with outputs from 125 bhp (Volvo 264) up to 408 bhp (Venturi 400 GT) on road cars.
At Renault, Peugeot and Citroën, PRV V6 units carry Douvrin “Z-codes”: Z6V and Z7V (2.7 L), Z7U (2.5 L turbo), Z7W (2.8 L) and Z7X (3.0 L). Volvo used its own B-codes: B27, B28 and B280. Each family has its own file: Z7U, Z7X, ZPJ4, Peugeot codes, Renault codes and Volvo B-codes.
Only the phase 1 Laguna 3.0 V6 12-valve (Z7X, 167 bhp) is a PRV. From 1997, a 60° “PR” V6 — L7X at Renault, ES9 at Peugeot — replaced the PRV on the Safrane, Laguna, Espace, 605 and XM. That engine is not a PRV. Safrane · Laguna · Espace file →
ACAV stands for “Admission à Caractéristiques Acoustiques Variables”: a variable-geometry intake on the PSA ZPJ4 3.0-litre 24-valve (200 bhp) that changes runner length with engine speed, giving nearly 80% of the torque from low revs on a naturally-aspirated V6. ZPJ4 file →
PRV stands for Peugeot-Renault-Volvo: the three carmakers of the alliance behind this V6, Volvo joining Peugeot and Renault in 1971 as an equal partner. The full story is in the History section.
At Douvrin, near Lens in northern France, by La Française de Mécanique (founded in 1969). All 970,315 units were built there.
In October 1974, in a Volvo 264 — the Douvrin lines had been running since January 1974. Volvo file →
On 15 June 1998, at Douvrin, after a total of 970,315 units across 24 years of production.
A Renault luxury saloon abandoned in July 1967. Its 3,550 cc 90° V8, developed jointly by Peugeot and Renault, passed its architecture on to the PRV when the 1973 oil crisis steered the project towards a V6.
Because its crankpins are not offset: on a 90° V6 this gives uneven firing. The second generation (1985) adopted offset crankpins and finally ran smoothly.
The 2,458 cc Z7U, launched in 1985 by the Renault 25 V6 Turbo — which also opened the second generation. Z7U file →
Yes, from 1990 at PSA: the ZPJ4 of the Peugeot 605 SV24 and Citroën XM V6 24S, 200 bhp naturally aspirated thanks to the ACAV variable intake. ZPJ4 file →
Around 5,200 rpm: below that, the long runners exploit resonance to swell torque (nearly 80% from low revs); above it, the geometry opens to free top-end power.
Around 910 bhp for the twin-turbo ZNS5 of the WM P88 in racing (1988). On the road: 408 bhp for the Venturi 400 GT.
Yes: despite the divorce pronounced in 1992, Volvo saloons kept fitting the PRV until 1997.
The 60° “PR” V6 that succeeded the PRV from 1997 (L7X at Renault, ES9 at Peugeot) on the Safrane, Laguna, Espace, 605 and XM. It is not a PRV.
Carburettors (including SU-HIF6), K-Jetronic mechanical injection, then Renix, LH-Jetronic, Bendix and Fenix electronic injection depending on the variant.

26 road models plus the Peugeot P4 V6 civilian series, across 11 marques: Peugeot (504, 505, 604, 605, P4 V6 civil), Renault (25, 30, Safrane, Laguna, Espace), Volvo (260, 760, 780), Alpine (A310, GTA, GTA Le Mans, A610), Venturi (200, 260, 400 GT), Citroën XM, Talbot Tagora, Lancia Thema, DeLorean DMC-12, Dodge Monaco, and Eagle (Medallion, Premier).

The DeLorean DMC-12 — the 1985 Back to the Future time machine — is powered by the PRV V6: a 2.85-litre, 130 bhp unit (code ZMJ-159) mounted at the rear. In the first film its engine roar was dubbed with a Porsche 928 V8, but the real engine is the PRV. DeLorean file →
The Venturi 400 GT, nicknamed “the French F40”: its 2,975 cc 24-valve PRV, twin-turbocharged by EIA, delivers 408 bhp — the highest output ever reached by the Douvrin V6 in a road car. 400 GT file →
On 11 June 1988, the WM P88 — powered by a 910 bhp twin-turbo PRV — was clocked at 407 km/h on the Mulsanne straight, driven by Roger Dorchy. The chicanes added in 1990 mean this all-time Le Mans speed record still stands. Record file →

Yes — in a very limited civilian series of around fifteen examples, produced around 1991–1992 by FAM. These P4s were fitted with the ZN3J, the 2.8-litre fuel-injected PRV V6 of the Peugeot 505 (170 bhp). They are among the rarest PRV-powered vehicles in existence. Separately, Peugeot Talbot Sport used a bored-out version — the ZN3J3 (2,975 cc, ≈ 220 bhp) — as a rapid-assistance vehicle at the Dakar rally from 1987. See the Tuners page.

The driver of the WM P88, clocked at 407 km/h on the Mulsanne straight on 11 June 1988 — the highest speed ever recorded at Le Mans.
Two Peugeot designers, founders of the WM team, entered at Le Mans every year from 1976 to 1989 — always on PRV power.
To coincide with the launch of the new Peugeot 405. The speed actually measured was 407 km/h.
Two chicanes were added to the Mulsanne straight in 1990, capping speeds well below 400 km/h: the record became eternal.

A Hartge prototype from around 1995: the 3.0-litre bi-turbo PRV lifted to 280 bhp in a far lighter front-wheel-drive car. Burned by the Safrane Biturbo's flop, Renault refused production — around five to seven were built.
