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

EF series. • CH1 (N/A): 1,997 cc Bore 86.0 mm (3.4 in) Stroke 57.3 mm (2.25 in) 285 bhp @ 9,800rpm (1973), 300 bhp @ 10,500rpm (1977) • CHS (Turbo): 1,997 cc Bore 86.0 mm (3.4 in) Stroke 57.3 mm (2.25 in) 500 bhp @ 9,500rpm (1975–1978) • CHS 2 (Turbo): 2,138 cc Bore 89.0 mm (3.5 in) Stroke 57.3 mm (2.25 in) 520/540 bhp @ 9,500rpm (1978)
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: 1149 cc 16v 75 bhp - 2001 (petrol engine used on
Dacia Sandero II,
Dacia Logan II,
Renault Clio and the
Proton Savvy) • D4Ft: 1149 cc 16v 100 bhp - 2007 (A turbocharged version of the D4F, with uprated internals to support the extra power produced) • D7F: 1149 cc 8v 54 bhp - 1996 (uprated to 57 bhp in 2001) 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: • E5F/E7F: 1171 cc • E5J/E6J/E7J: 1390 cc (E7J 260 with gearbox JH3 050 - is used in Dacia SuperNova. Solenza has E7J 262) • E7M/E4M: 1598 cc
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. • EF1 Turbo: 1,492 cc Bore 86.0 mm (3.4 in) Stroke 42.8 mm (1.7 in) 7.0:1 Compression 525 bhp (1977), 530 bhp (1979), 585 bhp (1982), 650 bhp (1983) • EF1 Bi-Turbo: 1,492 cc Bore 86.0 mm (3.4 in) Stroke 42.8 mm (1.7 in) 7.0:1 Compression 530 bhp (1979), 585 bhp (1982), 650 bhp (1983) • EF4(B) Bi-Turbo: 1,492 cc Bore 86.0 mm (3.4 in) Stroke 42.8 mm (1.7 in) 7.0:1 Compression 760 bhp (1984–1986) • EF15(B, C) Bi-Turbo: 1,494 cc Bore 80.1 mm (3.2 in) Stroke 49.4 mm (1.9 in) 7.5:1 Compression 815 bhp (1985–1986), 900 bhp (1986)
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 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)
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 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 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: • 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. • 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. • late 2008- :
