Renault F1 V10 Engine
Amabella Batton
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 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:
The C family (for the Clon-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:
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 Franois Castaing design was the predecessor of the famous EF series.
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 Mgane lineups:
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 Franois 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).
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.
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.
The J family (also referred to as the Douvrin engine) was an all-aluminum overhead camshaft inline-four design jointly developed with PSA. Introduced in 1977, it was phased out in 1996 and replaced by the F series.
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 the mid-2000s, although the petrol versions already launched by Nissan will almost certainly be used as well.
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:
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 coup, Latitude and designated V9X.
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:
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 sports car.
If im correct nissan are owned by Renault. Difference is ours is built in japan not France. Build a Renault in japan and see how good it is. Ive heard very little complaints about renaults from ppl I know with megane sports and Clio sports.
I work for Nissan, and can confirm it is an entirely Nissan designed, developed and manufactured engine. Because of the Renault alliance, they use it in a few of their larger cars, just as we use their diesels for some of our smaller cars, but the VQ35 in all it's guises is in absolutely no way a Renault engine. I'm just amazed how a few words from Jeremy Clarkson seems to overrule what used to be a very well known fact.
Even if it was a Renault engine - what about it. Renault have brought out some fine engines themselves and I seem to remember them winning an F1 championship or two with their own engines - surely thats as good if not better pedigree than Nissan?
I teach motor engineering and the number of times I hear 'but I heard on Top Gear', I then have to explain to them that top gear is the automotive equivalent of a lads mag and contains very little in the way of accurate facts.
Yeah its retarded, especially when considering torque is measured in so many ways on a car, normally newton meters or lb/ft but you even see it in kg/m and all sorts these days. The other one that annoys me is when journos or yanks describe torque in 'foot pounds' what the hell is that? How many feet you can get in a pound?
A breakthrough from France will bring about a more powerful, more compact and cleaner electric motor: Renault Group and Valeo are combining their expertise to create a new electric motor generation. As a result of the regular conversations between the carmaker and the equipment manufacturer, this partnership that started in 2021 soon grew into a co-development journey. They each pooled one key part (Renault Group the rotor, Valeo the stator) as well as their expertise in technology development and production. The are currently fine-tuning their E7A high-tech motor.
This third-generation motor will also help shorten battery charging times as the system will be built for 800 volts instead of 400 volts, the standard today. And the stator by Valeo will boost power and efficiency. The new E7A motor, as a result, will unleash up to 200 kW. It will also supply more power without consuming more electricity. And the E7A motor uses hairpin technology to assemble copper wires, a Valeo specialty since 2010.
At this stage, the engine is still under development. There are other stages to go through before it can reach serial life. The mass production of this new-generation engine will start at Renault Group's Clon factory at the end of 2027.
Was wondering if anybody had any info on the Renault 6 cylinder diesels that Mack put into their small cabovers from the early 80's on? I am looking to repower a GMC 1 ton crew cab and theought this might be a way to go. Any guidance? Let me know
I had one in an 89 CS-300P truck that I put a 22 ft. steel rollback bed on. It gave very good service as far as reliability. Good starting engine without being plugged in on winter nights, backed by a close ratio 6 speed overdrive transmission.
i had one for 8 yrs, i got the truck at a sale for the bed but i ran it until the cab rotted off, the motor got good fuel mileage and ran like a top, i still have it, dumb me got a late model truck with a cat in it and switched the bed over, the 1st trip out it was on the big hook coming home with 2 broken pistons, Mack is not no higher than cat when it comes to parts
Thanks guys for the replies. I realize that nothing is cheap anymore no matter what you are doing. I figured that if I could start at a reasonable cash outlay it would make life easier. It sounds like the Renault may be a good way to go then. I will keep checking here to see if anybody else has any more input Greg
