List of Renault engines
From Wikipedia, the free encyclopedia
Engines used by French automaker Renault SA have historically been referenced in technical specifications along two distinct systems:
- a purely numeric system used from the origins of the company until the mid-1980s
- an alphanumeric system in use since then

[edit] Numbering systems
[edit] 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.
[edit] Alphanumeric
The system in use since the mid-1980s is of the format XnY-zzz where
- X is a letter specifying the engine family
- n is a one-digit code specifying the engine architecture as follows:
- Petrol engine with single-barrel carburetor and parallel valves (a layout often but not always associated with an overhead valve design)
- Petrol engine with double-barrel carburetor and parallel valves
- Petrol engine with single- or multi-point fuel injection and parallel valves
- Petrol engine with four valves per cylinder
- Petrol engine with single-barrel carburetor and crossflow valve layout
- Petrol engine with double-barrel carburetor and crossflow valve layout
- Petrol engine with single- or multi-point fuel injection and 2 or 3 valves per cylinder in a crossflow layout (includes also an early 16-valve version of the F-type engine)
- Diesel engine with indirect injection (prechamber)
- Diesel engine with direct injection
- Y is a one-letter indicator of displacement:
- A: under 750cc
- B-U: from 750 to 2250 cc in 50-cc, then 100-cc increments as displacement increases
- V-Z: above 2250 cc in increments larger than 100cc
- zzz is a three-character alphanumeric code (usually starting with 7 or A) referring to key details of the variant's configuration (e.g., turbocharged, implemented in a specific vehicle, manual or automatic transmission, catalytic converter or not, etc.)
[edit] Engine families
[edit] 6DE
The 6DE engine is an overhead camshaft Diesel V6 sourced from Perkins and used in the Vel Satis sedan and Espace minivan:
- 6DE1: 2958cc
[edit] A
The A engine was an all-aluminum overhead valve inline 4 designed in the mid-1960s for the Renault 16 and produced in three variants:
- A1K: 1470cc
- A1L: 1565cc
- A2M/A3M: 1647cc
[edit] B
The B family (for the Billancourt factory where it was produced) was a cast-iron overhead valve inline-4 designed in the mid-1940s for the 4CV and also used in the Renault 4 and Dauphine:
- 748cc (out of production before alphanumeric codes were introduced)
- 782cc (out of production before alphanumeric codes were introduced)
- B1B: 845cc
[edit] C
The C family (for the Cléon factory where it was produced, also referred to as Sierra in early variants) was a cast-iron overhead valve inline-4 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 1992 Twingo:
- C1C: 903cc
- C1E: 1108cc
- C1G/C3G: 1237cc
- 1289cc (out of production before alphanumeric codes were introduced)
- C1J/C2J/C3J: 1397cc
[edit] D
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:
- D4F: 1149cc
- D7F: 1149cc
A 1000-cc D7D version was abandoned after early development.
[edit] 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:
- E5F/E7F: 1171cc
- E5J/E6J/E7J: 1390cc
- E7M/E4M: 1598cc
[edit] F
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.
- F1N/F2N/F3N: 1721cc
- F7P: 1764cc
- F3P: 1794cc
- F3R/F4R/F7R: 1998cc
- F8Q/F9Q: 1896cc
[edit] G
The G engine was designed in the late 1980s to be a modular family of overhead camshaft inline 4- and 5-cylinder petrol and Diesel engines. A G7R petrol and a G8T Diesel variant were in development when Renault announced a merger with Volvo who was designing its own modular family along the exact same lines. The group made the business decision to cancel all G development save for Diesel versions. Despite the breakdown of the merger in 1993, Renault used Volvo petrol engines (Type N) in its mid- and full-size models until the early 2000s
- G8T/G9T: 2188cc
[edit] H
The H family is a major evolution of the F family.
- H4R: 1998cc
[edit] J
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.
- J5R/J6R/J7R: 1995cc
- J6T/J7T: 2165cc
- J8S: 2068cc
[edit] K
The K type is a major evolution of the E type.
- K4J: 1390cc
- K4M: 1598cc
- K9K: 1461cc
[edit] L
The L type is an aluminum overhead camshaft petrol V6 developed jointly with PSA, who refer to it as the ES engine:
- L7X: 2965cc
[edit] M
The M engine is an overhead camshaft engine developed jointly with Nissan, who refers to it as the HR engine. Only one Diesel version is in use at Renault as of mid-2006, though the petrol versions already launched by Nissan will almost certainly be used as well
- M9R: 1995cc
- M4R: 1997cc (petrol engine used on Renault Clio III; launched november 2006)
[edit] N
The N engine is Renault's internal designation for the modular overhead camshaft inline-4 and inline-5 sourced from Volvo in the 1990s and used on the Laguna and Safrane sedans:
- N7Q: 1948cc
- N7U: 2436cc
[edit] S
The S engine was a cast-iron overhead valve 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:
- S8U/S9U: 2445cc
- S9W: 2799cc
[edit] V
The V engine is Renault's internal designation for the Nissan VQ engine, an overhead camshaft V6 used in the Vel Satis sedan and Espace minivan
- V4Y: 3498cc
[edit] X
The X engine (referred to as XU 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:
- X1G: 1219cc
- X2J: 1360cc
[edit] Z
The Z engine, also known as the PRV V6, was a cast-iron 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, Espace, and Alpine.
- Z7U: 2458cc
- Z6V/Z7V: 2664cc
- Z7X: 2975, then 2963cc
