General Chatter


The regular Aston V12 uses roller rockers http://www.motoiq.com/magazine_articles/id/2684/nerds-eye-view-2014-aston-martin-vanquish.aspx

It was designed by Ford and Cosworth http://media.ford.com/article_display.cfm?article_id=4588

Cosworth assembled the V12 engines for a year http://www.astonmartins.com/factory/db9_production.htm http://media.ford.com/article_download.cfm?article_id=15421

Cosworth still casts the heads and blocks http://www.mahle-powertrain.com/C1257126002DFC22/vwContentByUNID/C807923162DF211EC12578CD00529814/$FILE/Castings%20Flyer%20EN.pdf http://www.mahle.com/C1256F7900537A47/vwContentByKey/W26FKK5C803MARSEN/$FILE/Press%20Information%20MAHLE%20Expands%20Powertrain%20Capabilities_en.pdf

Aston One-77 uses (DLC coated) DAMB cam followers like the later Duratec engines http://www.enginetechnologyinternational.com/downloads/Aston_Martin.pdf

Cosworth build the One-77 engine http://www.themanufacturer.com/articles/cosworth-engine-of-growth/ http://cosworth.com/pr-media/news-archive/automotive/aston-martin-reveal-one-77-supercar/

Guys, try to keep the chatter from hiding the "Contents" box, ok? Additions belong at the bottom of the page, or under the proper heading, not at the top, pushing everything down the page. Kythri 19:38, 1 November 2006 (UTC)[reply]

Regarding the Aston Martin V12: The description of the engine as being designed by Cosworth is in disagreement with the description on the Aston Martin V12 Vanquish page (which says the engine was designed by Ford Research).

I'm pretty sure these are several completely different engine families under one name.

The 2.5L and under v6 engines used mostly in Europe (Mondeo, X-type, etc.) was developed in conjunction with Yamaha if I'm not mistaken. It also spawned the Taurus SHO v8, which was a 2.5L with two cylinders added on. There are rumours that Ford/Yamaha may bring out a new v8 variant for use in FWD Volvo's and Fords/Lincolns.

The 3.0L and upcoming 3.5L Duratec is a North American design, and comes in many forms from the SOHC Taurus v6 to the DOHC VVT Mazda variant to the even more powerful Jaguar and Lincoln versions. The Aston Martin v12 is basically two of these engines end-to-end.

The new "Duratec" i4 engines are the new global family designed by Mazda in Japan.

The DuraTORQUE diesels are PSA designs.

I'll have to check all this tho' -- stewacide 23:50, 7 Apr 2004 (UTC)

Hi, I agree it's pretty confusing when several apparently different engines all start using the same name. There's a lot of confusion in the motoring press that is perpetuated in all kinds of places that makes it hard to estabish the actual facts. For instance, I used to think that all Zetecs were based on a Yamaha design, but I'm now fairly certain that only the enhanced Zetec-SE was Yamaha, appearing first as the 1.25.
The 3.0L is used in Europe in both the Mondeo and X-Type ranges and appears to me to be a bored out 2.5 engine, as it is very similar. Should be confirmed though.
PS I'm pretty sure that the original Duratorq engines (2.0TDDI in 2000 Mondeo) were nothing to do with PSA, but Ford did work with them when producing the new 1.6 and revised 2.0 units that are appearing now. That's why I think people are mistaking them for original PSA designs.
I'm actually of the opinion myself that the only true European Duratec is the original 2.5 V6 in the Mondeo, the rest just seem to be improved Zetec engines (re-worked by Mazda, like you say) that are re-branded. Still, if Ford call them Duratec then that is how I have to classify them..
Messy business isn't it? I prefer the GM system were engines are given well known code names *and* a brand name, it's so much more obvious what things are!
Let me know what you find! Cheers --Pete Richardson 10:02, 8 Apr 2004 (UTC)
I've also heard that the 2.5 family was designed by Porsche so I'll have to look into it. I knew the 3.0 was used in Europe (the S-type also has it, and I think the XJ in Europe does as well). There's also the question of how the Volvo i5s and i6s relate to other corporate engines. I'm also not sure what the story is with the new 3.5 v6 program - I've heard it's supposed to be very modular and can stretch anywhere between ~3.2 and ~3.8 litres.
Either way the Ford DOHC v6s are my favorites right now, the 2.5 especially. It's a tragedy we don't get the Mondeo/Cougar in North America anymore, although judgeing by the Zephyr concept the Futura may make up for it!!!
And as if things wern't complicated enough Ford has the existing ~4.0L v6 family as used in the Ford/Mercury North American minivans, a bunch of SUVs (Explorer, etc.), Ford and Mazda pickups, Mustang, and I think some upcoming Land Rover products. I'm not sure if this is ever refered to as a Duratec. I think it may be a cut down version of the Crown Vic/Town Car "Windsor" engine but again I'd have to look it all up. I'm also not sure if the new large v6s are meant to replace this family or not - they seem to have given it something of an overhaul with the new Mustang...
And we don't have to include them all under the same article if they aren't related. I'll try and find the internal designations for the families and make seperate articles for each, with this page acting as a pointer.
...when I'm done exams that is ;) -- stewacide 13:06, 11 Apr 2004 (UTC)

Duratec derivation


The original Duratec V6 was the 2.5L version, and Ford had significant design help from Porsche. The block architecture (a short block with a girdle, instead of a deep skirt block with bearing caps) is unique in Ford. It was launched in Cleveland Engine Plant #2 about 1994.

The 3.0L was the bored out version of the same engine, and they are build on the same line, you need to know your parts to distinguish them.

Subsequently Ford decided to use the Duratec name as a marketing tool and slapped it on a bunch of other engines.

In 2004 Ford expanded capacity by adding a line at Cleveland Engine Plant #1 to support the Ford Five Hundred. This is a more flexible line and can be converted to other engines in the future.

The Duratec 35 is a new design using an old name.--Pmeisel 17:45, 5 Feb 2005 (UTC)

I'm trying to work out the myriad of Ford engine rename jobs. Witness the Ford Zetec engine edits! It's frustrating - they reuse the Zetec and Duratec names frequently. Does anyone know the actual code name for the 2.5/3.0L Duratec V6? Was it Duratec? I sure hope not. Otherwise, we can disamb the engine families from the marketing name as I did on the Zetec article. Still in progress, BTW... --SFoskett 04:47, Feb 7, 2005 (UTC)
Well, I hate to disappoint you, but the the 2.5/3.0 was actually known as the Duratec from preproduction. I first heard it a couple years before the first one in a vehicle. All the other "Duratecs" are wearing a marketing label only. Zetec was the 4 cylinder replacement for the CVH. It is complicated..... Pmeisel 04:39, 8 Feb 2005 (UTC)

Separating families from marketing names


You know, I think that is a great idea. The 4 cylinder and 6 cylinder designs have nothing in common but a blue oval... I would be glad to help as much as possible.


Could anyone state what sort of engine is this ?

etis.ford.com reported on the VIN Number:

Version: Series 30

Engine: 1.25 Zetec-S / Duratec DOHC EFI (75PS)

Local Police registration authorities stated in the vehicle registration certificate: 1242 cmc Code: JH1/FUJA I

Is this engine related in any way to the paragraph on "The advanced Zetec-SE was developed in collaboration of Yamaha and Mazda, under the Sigma codename" Why is it codenamed FUJA and not Zetec ?

Support I Support the proposal to separate the engines into their respective families and leave Duratec as a disambiguation page. VX1NG (talk) 13:50, 25 June 2014 (UTC)[reply]

More name games


The Mazda MZI, Duratec ST, and Duratec SE 3.0L are all variants of the basic RFF, built down the same line, and very difficult to distinguish from one another... not sure how best to incorporate that in the article... I try to post a summary of applications here if that will help. The new Fusion/Milan/Zephyr motor is also an RFF variant.

HP Rounding


I see 232 HP for the Jag and Lincoln using DAMB...but the page claims the existence of 3.0L duratecs up to 240 HP. Is this just rounding or do such things exist?--Skunkworx 23:07, 5 September 2006 (UTC)[reply]

If you look around the 3.0L S-Type was listed at 240hp when it first came out in 2000 model year. Later, it was rated at 235hp. The Jaguars and Lincoln Duratecs have different intakes and exhaust which can make for slightly different ratings. Things of note that could be added/revised to the webpage are:

1) There are other versions of the DAMB Duratec than the 3.0L. Jaguar also uses a 2.5L DAMB in the X-Type and S-Type. The X-Type is also available with a 2.0L DAMB Duratec V6 engine. They use the same block as the 2.5L but put in a short stroke crankshaft, longer con rods, and different piston. Jaguar calls the Duratec engines in their vehicles AJ-V6. So the the 3.0L is the AJ30, etc. The 3.0L DAMB engine for the 2000-2002 Lincoln LS did not have variable cam timing. In 2003, VCT was added to the Lincoln LS.

2) The Ranger has never used the 2.5L Duratec V6. The 2.5L engine that was used in 1999/2000 was a four cylinder engine.

3) The 2.5L Duratec SVT used in the 1998-2000 Contour was also available in the 1999-2000 Mondeo. I believe it was referred to as the Mondeo ST200 at the time. The extra power of the SVT version was gained through the use of higher compression pistons, premium fuel, more aggressive camshaft profiles, and Extrudehoning of the intake tract. --Procyon5 03:03, 18 October 2006 (UTC)[reply]

6.0L GT90


The 6.0L from the GT90 was based on two 90-degree V-8 blocks, not two V-6's. --Eljamoquio 20:50, 19 October 2006 (UTC)E 05:21, 26 Mar 2005 (UTC)[reply]

Agreed, I searched around the web and found several pictures of the GT90 engine. It most definately has a 90° angle between cylinder banks instead of the 60° angle found on the Duratec V6. --Procyon5 16:53, 24 October 2006 (UTC)[reply]

Cosworth Involvement


I'm removing this section under References:

The Aston Martin V12 engine was designed at Ford Research in the USA. Cosworth Technologies was originally contracted to manufacture the engine, but had no involvement with the design. Previous articles which correctly recount this engine's development have appeared in Automotive Industries magazine.

It contradicts other information in the article, and if in fact it is valid, it doesn't belong under "References". The submitter needs to learn how to properly edit the article. Kythri 19:37, 1 November 2006 (UTC)[reply]

I'm removing it entirely. There is no reference, and the original engine was designed by Ford's Advanced Engines.--Eljamoquio 21:00, 17 November 2006 (UTC)[reply]



I am not so into this topic but have a question. The Volvo 5 cilinder engines are sometimes (and implicite also on this page) called duratec engines. Is this correct because in some places they are not called duratec? Who can clarify? Robkraai (talk) 08:41, 23 June 2008 (UTC)[reply]

Duratec HE


The European 1.8 L (1796 cc) and 2.0 L (1988 cc) units are not based on Mazda MZR engine; the displacements are the same as for the Zetec SE (Sigma family), while Mazda versions displace at 1798 cc and 1999 cc. This clearly indicates that Duratec HE uses very similar engine block, and even if it uses some technology from the MZR family, it's still heavily revised all-alloy Sigma block, not a Mazda L or Z block. Despite all the blah blah blah about "our new global engine", Ford just plays the same confusing name games with its old stuff...

There is no Focus 2.3 or EcoSport 2.3 here in Brazil, only 2.0 ones. I suggest to remove both models from the "2.3" section. —Preceding unsigned comment added by (talk) 18:17, 2 March 2009 (UTC)[reply]

Duratec 4 cylinder engines


There seems to be everlasting confusion regarding the origin of the major "Duratec" I4 engines.

If your Duratec or EcoBoost, petrol or diesel, has the following bore and stroke dimension:

78mm x 83.6mm - 1.6L
83mm x 83.1mm - 1.8L
87.5mm x 83.1mm - 2.0L
87.5mm x 94mm - 2.3L
89mm x 100mm - 2.5L
86mm x 86mm - 2.0L Diesel
86mm x 94mm -2.2L Diesel

then it is absolutely and definitively a 100% Mazda engineered long block. Not co-engineered, purely derived from the brains in Hiroshima. Cheers —Preceding unsigned comment added by (talk) 01:59, 2 November 2010 (UTC)[reply]

So, are Europe Duratec-HE and American Duratec based on the same Mazda L-engine and what are the differences, if any? We someone who has experience with Ford engines and service manuals, so we can clarify this once and for all. --Dmitry (talkcontibs ) 17:42, 5 April 2011 (UTC)[reply]

The question was "are Duratec-HE and the American Duratec are the same as Mazda L-engine" and I still can't hear the answer to that. -- (talk) 03:31, 3 June 2011 (UTC)[reply]

i've been through tons of web sites and pdf documents. and i'm shure 1.8/2.0/2.3 Duratec engines are Mazda engines, still they have few differences. 2.0 in 2007 mazda 3 produces 150 hp while in 2008 2.0 focus produces 145 hp. It's like new diesel engines made by Ford and PSA. Same engine is in new mazda 3 but it's little different cause mazda optimized it for it's own cars, same thing ford did with Mazda L engines.

so, Ford Duratec are heavily based on mazda MZR enginesZunaOFP (talk) 14:34, 6 February 2012 (UTC)ZunaOFP[reply]

heres the link that confirms that ford duratec is mazda/ford engine http://media.ford.com/article_display.cfm?article_id=13626 ZunaOFP (talk) 20:47, 21 February 2012 (UTC)ZunaOFP[reply]

When the new Mondeo was launched in 2000, Ford introduced the new Duratec engine. And instead of using the quite old Zetec-E engine for the new car they decided to use the modern Mazda MZR instead. And because Ford didn't want to tell everybody it's just a Mazda engine, they relabled it as Duratec. All Duratecs are the same, they share the same bolt pattern (which is different from the standard Ford CVH/Zetec/DOHC/Sigma) for the gearbox. That's one of the reasons why the Duratec is not a Sigma type. Although both have an alloy engine block and the inlet in front of the engine. But theres no part that is interchangeble. The Duratec is also called Duratec-HE. HE stands for homogenous engine. Why? Because Ford intended to use it all over the world. It was used in Mazda vehicles and in Ford vehicles in nearly all countries. That is what you call Global-I4. But quite confusing is the fact that Ford started to name all of their petrol engines in Europe Duratec. That's why the Duratec-HE is called Duratec-HE, although it usually is labelled as Duratec. More confusing is the fact that the Zetec-E was used until the second generation of the Focus was launched. AND it had still got the Zetec badge on the rocker cover. Why? No one knows for sure. Probably they renamed the Sigma units because they were quite new and Ford intended to use them for a quite long time and they knew that they will stop production of the Zetec-E in 2004. BUT: The european spec Focus RS (2.0 Zetec turbocharged, 215 PS) and the Focus ST170 (2.0 Zetec VCT, 172 PS) used an uprated Zetec engine, both with internals altered to their purpose (turbocharge/high-rev N/A) AND they were badged as Duratec-RS and Duratec-ST. That's why there were some 2.0 Duratec units with 1988 ccm capacity instead of the 1.999 you'd expect when you think of the MZR based Duratec-HE. Sure there were different hp figures of the engines, but that's mostly because of the use of the engines. The 145 PS 2.0 Duratec was used for Mondeo, Focus, C-Max etc. and the 150 PS version was used for the small and fast hatchback Fiesta ST (Fiesta ST150/Fiesta XR4 in oz) with a more agressive engine mapping, different camshafts and a special exhaust system. The units in the bigger cars were intended to be more comfortable with a better mpg and more low-down power. Summary: Duratec is the name for most of the petrol engines, Ford Europe fitted to their vehicles since the beginning of the new century. This includes the old 2.5 V6 24V, the rebadged Sigma units, the Zetec-Rocam, the 1.2 8V Fiat unit used in the new Ford KA, the two Zetec-E variants of the Focus RS and ST170, the Volvo I5 engines used in Focus ST (2.5) and Focus RS/RS500 (2.5) and some more. Duratec-HE is also labelled Duratec, BUT, it's the Mazda MZR based engine, used in most markets in the world.
