List of Renault engines

Engines used by French automaker Renault SA have historically been referenced in technical specifications along two distinct systems:

Numbering systems

Numeric

The numeric engine referencing system used until the mid-1980s was simply the chronological sequence of engine development projects. Thus, variants based on the same engine block may have unrelated numbers.

Alphanumeric

The system in use since the mid-1980s is of the format XnY-zzz where

Engine families

A

The A engine was an all-aluminum overhead valve inline-four designed in the mid-1960s for the Renault 16 and produced in three variants:

B

The B family (for the Billancourt factory where it was produced,[1] also referred to as the Ventoux engine) was a cast-iron overhead valve 3-bearing crankshaft inline-4 designed in the mid-1940s for the 4CV and also used in the Renault 4 and Dauphine:

C

The C family (for the Cléon-Fonte factory where it was produced, also referred to as Sierra in early variants) was a major evolution of the B type, being also a cast-iron overhead valve inline-four but now with a five-bearing crankshaft, designed in the early 1960s for the Renault 8. An extremely sturdy, low-cost design, it was continuously refined over its 35-year career and was used in every supermini and compact Renault type up to and including the 1993 Twingo:

CH

The CH-serie was a 90° V6 engine developed by Gordini for Renault's autosport activities, the engine was used by Equipe Renault Elf in Formula One from 1973 to 1978. This François Castaing design was the predecessor of the famous EF series.

285 bhp @ 9,800rpm (1973), 300 bhp @ 10,500rpm (1977)

500 bhp @ 9,500rpm (1975–1978)

520/540 bhp @ 9,500rpm (1978)

D

Main article: Renault D-Type engine

The D family is the successor to the smaller versions of Type C, introduced in the mid-1990s, and is a cast-iron overhead camshaft inline-4 that powers the Renault Twingo:

A 1000 cc D7D version was abandoned after early development.

E

The E family (for Energy) is the successor to the larger versions of Type C. It is a cast-iron overhead camshaft inline-4 introduced on the Renault 19 in 1988 and widely used in the Clio and Mégane lineups:

EF

The EF-serie was a 90° V6 Turbocharged engine jointly developed by Renault and Gordini, the engine was used by Equipe Renault Elf in Formula One from 1977 to 1985. This engine derived from the CH series designed by François Castaing, the F1 engine was developed by Bernard Dudot.

525 bhp (1977), 530 bhp (1979), 585 bhp (1982), 650 bhp (1983)

530 bhp (1979), 585 bhp (1982), 650 bhp (1983)

760 bhp (1984–1986)

815 bhp (1985–1986), 900 bhp (1986)

F

Main article: Renault F-Type engine

The F inline-4 family (for Fonte, French for cast iron) was the successor to the A family. Launched in 1981 on the Renault 9 and Renault 11, it has been the mainstay of Renault's engine lineup through the early 2000s in a succession of increasingly powerful petrol and Diesel variants in overhead camshaft configurations. It was also Renault's first production four-valve design. It is being replaced by the M engine resp. R engine (diesel only).

G

Main article: Renault G-Type engine

The Renault G-Type was a family of naturally aspirated and turbocharged straight-4 indirect injection and commonrail diesel engines. Production started in 1993 and the engines were used over a decade until 2011, with improvements in power and torque output and fuel efficiency.

H

Main article: Nissan HR engine

The H engine is an overhead camshaft engine developed jointly with Nissan, who refers to it as the HR engine. 't' means 'turbo-charged'. And 'k' means 'kaizen' which means 'revisioned' in Japanese.

J

Main article: Douvrin engine

The J family (also referred to as the Douvrin engine) was an all-aluminum overhead camshaft inline-4 overhead camshaft design jointly developed with PSA. Introduced in 1977, it was phased out in 1996 by the F series.

K

Main article: Renault K-Type engine

The K type is a major evolution of the E type.

L

Main article: PSA ES engine

The L type is an aluminum overhead camshaft petrol V6 developed jointly with PSA, who refer to it as the ES engine:

Renault used this engine first in the Laguna in 1997, shortly after it became available in the Safrane, and the Espace rated 194 PS (143 kW). Engines after 2001 got a new injection system and variable valve timing, this variant is rated 211 PS (155 kW), was being used in the Avantime, and the Laguna II V6. The engine was also used in the Clio V6, rated 230 PS (169 kW) in the phase 1 vehicles, and 255 PS (188 kW) after the facelift.

M

Main article: Nissan MR engine

The M engine is an overhead camshaft engine developed jointly with Nissan, who refer to it as the MR engine. Two Diesel versions are in use at Renault as of mid-2009, although the petrol versions already launched by Nissan will almost certainly be used as well.

N

Renault's N designation refers to the sourced all-aluminum Volvo modular 4-valve DOHC inline-4 -5 engines fitted in the Laguna and Safrane.

P

Main article: DMAX V6 engine

The P engine is an overhead camshaft Diesel V6 sourced from Isuzu and used in the Vel Satis sedan and Espace minivan:

R

Main article: Renault R-Type engine

The R engine is a straight-4 Diesel engine based on its predecessor F9M. Production started in 2011.

RS

The RS Prefix is Renault's internal designation for their Formula 1 racing engines.

S

The S engine was a cast-iron overhead camshaft inline-4 Diesel engine sourced from Italian engine manufacturer SOFIM. It has been used in the Trafic and Master utility van and the Safrane sedan since 1981:

V

Main article: Nissan VQ engine

The V engine is Renault's internal designation for the Nissan VQ engine, an overhead camshaft V6 used in the Vel Satis sedan, Latitude and Espace minivan. The V designation is also used for an unrelated diesel V6 engine jointly developed by Renault and Nissan, used in the Renault Laguna coupé, Latitude and designated V9X.

X

The X engine (referred to as XZ and XY by PSA) was an all-aluminum overhead camshaft inline-4 jointly developed with PSA. Introduced in 1974, it powered the ill-fated Renault 14 midsize car and was phased out in 1982 by evolutions of the C series:

Z

Main article: PRV engine

The Z engine, also known as the PRV engine, was an aluminium overhead camshaft V6 developed jointly with PSA and Volvo in the early 1970s. Introduced in 1975 on the Renault 30, it also powered the 25, Safrane, Laguna, Espace, and Alpine. It also famously powered the Delorean DMC-12 sports car.
