List of Renault engines

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.

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:
  1. Petrol engine with single-barrel carburetor and parallel valves (a layout often but not always associated with an overhead valve design)
  2. Petrol engine with double-barrel carburetor and parallel valves
  3. Petrol engine with single- or multi-point fuel injection and parallel valves
  4. Petrol engine with four valves per cylinder
  5. Petrol engine with direct petrol injection, prior to F engine: single-barrel carburetor and crossflow valve layout (deprecated)
  6. Petrol engine with double-barrel carburetor and crossflow valve layout
  7. Petrol engine with multi-point fuel injection with half-spherical combustion chambers and two valves per cylinder (includes also an early 16-valve version of the F-type engine)
  8. Diesel engine with indirect injection (prechamber)
  9. Diesel engine with direct injection
• Y is a one-letter indicator of displacement:

  A: under 750 cc

  B-U: from 750 to 2,250 cc in 50 cc, then 100 cc increments as displacement increases

  V-Z: above 2250 cc in increments larger than 100 cc

• 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. An odd number refers to an engine configured for automatic transmission, while an even number is meaning manual gearbox.)

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:

• A1K: 1,470 cc
• AxL: 1,565-1,605 cc (also used in the R15 and R17 models).
• AxM: 1,647 cc

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

• 748 cc (out of production before alphanumeric codes were introduced)
• 782 cc (out of production before alphanumeric codes were introduced)
• B1B: 845 cc

The new B family three cylinder petrol engine appeared from 2016. NMKV developed the BR06 engine based on this engine for Nissan and Mitsubishi Kei car

• B4A: 799 cc Renault Kwid, Datsun redi-Go
• B4D: 999 cc (71x84); Renault Kwid, Renault Twingo, Renault Clio, Renault Triber

The C family (for the Cléon-Fonte factory where it was produced, also referred to as Sierra in early variants), 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:

• C1C (689): 956 cc (65x72); 32 kW
• C1E (688): 1,108 cc (70x72); 28-34 kW
• C1G: 1,237 cc (71,5x77); 40 kW
• C3G: 1,239 cc (74x72); 40 kW; monopoint injection
• 810: 1,289 cc (73x77; out of production before alphanumeric codes were introduced); 32-47 kW
• C3J: 1,390 cc (75,8x77); 43 kW; monopoint injection.
• C1J/C2J (847): 1,397 cc (76x77); 43-52 kW normal aspiration / 77-88 kW turbo
• C6J (840): 1,397 cc (76x77 with hemispherical head); 68 kW normal aspiration, 79-116 kW turbo
• C7K: 1,430 cc (76x79)

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.

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: 1149 cc 16v 75bhp - 2001 (petrol engine used on Dacia Sandero II, Dacia Logan II, Renault Clio and the Proton Savvy)

• D7F: 1149 cc 8v 54bhp - 1996 (uprated to 57bhp in 2001)

A 1000 cc D7D version was abandoned after early development.

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: 1171 cc

• E7M/E4M: 1598 cc

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.

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).

• F1N/F2N/F3N: 1721 cc
• F7P: 1764 cc (injection R19 16V 138HP)
• F3P: 1794 cc
• F4P: 1783 cc (evolution of the F3P, 16V with variable valve control on the inlet camshaft)
• F3R/F4R/F7R: 1998 cc
• F5R: 1998cc (direct fuel injection - IDE - only 2 years in production, used in the Megane Coupé and the Laguna II)
• F8Q/F9Q: 1870 cc (indirect injection/direct injection/common rail)

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 same lines. The group decided to cancel the petrol versions, but diesel production started in 1993 and they were built for nearly two decades, until 2011. Despite the breakdown of the merger in 1993, Renault did use Volvo petrol engines (Type N) in its mid- and full-size models until the early 2000s.

• G8T/G9T: 2188 cc
• G9U: 2464 cc

H engines summarize two families of gasoline engines, the smaller with a max. cylinder bore of 72.2 mm and a larger family with typically 78 mm bore:

1. The smaller family covers 0.9 - 1.33 litres of swept volume and was co-developed by Renault, Mercedes-Benz and Nissan. The largest naturally aspirated version has three cylinders and 1.0L, four cylinder engines are not known without turbocharging. In most cases Renault or Mercedes introduced these engines into their cars.

1. The bigger family covers 1.0 - 1.6 litres of swept volume and are co-developed by Renault and Nissan with no known involvement from Mercedes-Benz and Mercedes-Benz does not utilize any one of these engines. Engines are mostly naturally aspirated while some versions with turbo or super charging are available. Most engines had been introduced by Nissan.

Multiple usage of the Renault H series resp. Nissan HR name plates may cause some confusion because both families offer a three-cylinder 1.0L version and another 1.2L version with 3 resp. 4 cylinders. It appears to be that the earlier engine was named HR10 (bore 78mm x 69.7 mm stroke) while the later got HRA0 (72.2 x 83.1) resp. the earlier was named HR12 (78 x 83.6) and the later got HRA2 (72.2 x 73.1). Renault may not suffer from this because they never utilized the bigger three cylinder engines. Nonetheless both families have DOHC and an aluminium alloy crankcase and cylinder head. For this engine family some of the naming system has been taken over from Nissan: 't' means 'turbo-charged' and 'k' stands for 'kaizen' which means 'change for better' or 'continuous improvement' in Japanese.
