Mazda...Duratec or not??????

[SOON2BN-FOCUS]

I have been trying to figure this out, I know I have heard people say the engine in the Mazda3 is a duratec and is identical to the 2.3L in the Focus. There are all types of claims out there. I have searched and found claims stating that the 2.3L is Mazda engineered. And otheres stating that the 2.3L is Ford engineer.
Here is what I found:

The new engine family also is leading the way in modern, cost-efficient manufacturing. Four plants on three continents will build Duratec I-4s, and all will benefit from the efficiencies and quality improvements offered by flexible manufacturing techniques.

A number of Ford and Mazda brand vehicles currently offer or will offer the new engine in both "east-west" and "north-south" configurations for front- and rear-drive applications.

In addition to the Focus, these applications include:

* Ford Mondeo, with 1.8- and 2.0-liter versions, built at Valencia Engine Plant in Spain.
* Ford Ranger, with the 2.3-liter variant built at the Dearborn (Mich.) Engine Plant.
* The restyled Mazda MPV minivan built at Mazda’s Hiroshima plant in Japan.
* The all-new Mazda6 (sold as the Mazda Atenza in some countries), which is sold with displacements of 1.8-, 2.0- and 2.3-liters, depending on the market.
* Both the Ford Escape Hybrid, which will debut next summer, and Ford Futura, which will launch in 2005, will use derivatives of the 2.3-liter engine.

And here is what someone else found:

The 2.0 and 2.3L Inline 4s in the Mazda 3 are part of Mazda's MZR engine family, which is offered worldwide in displacements of 1.4, 1.6, 2.0, and 2.3L for the gasoline engines. Also offered from this line are 1.4, 1.6, and 2.0L common rail diesel engines. I believe the diesel versions are SOHC. The 2.0L 4cyl. in the current Focus is from Ford's Zetec line, and the 2.3L offered in 2004 for the ZTS and ZTW is a reworked Mazda MZR engine. Its subsequently been renamed the Duratec 23E.

The Ford engine, the Duratec23E, is found in the 2003+ Focus. It is designated a PZEV (partial zero emissions vehicle) engine. This Ford version of the Mazda MRZ engine was apparently co-developed by Mazda and Ford, using casting technologies developed by Cosworth.


What is your guys take on this? If you have links post them.
I don't wanna win any arguements, just wanna know the facts about my car.

I'm sure biker16 will chime in with good info.

My understanding is the 2.3 in the Mazda is basically the same engine as the 2.3 Focus although the 3 has variable valve timing while the Focus does not.

well... just as a comparison... the 2.0l zetec block is a Mazda block...

it's a pretty safe bet that the 2.3 duratec is identical in both cars

Thats what I've been hearing lately. So the 2.0L Zetec, 2.3L Pzev, and the 2.0L and 2.3L in the Mazda3 and 6 are mazda designed engines. And the only differences are the Pzev equipment on the Focus and the VVT on the Mazda's. But bottom line the are identical engines.

the zetec may or may not be mazda designed, but it defintely has nothign to do with the current duratec line. THere WILL be a 2.0 duratec/MZR in the focus...in 2005. ITs one hell of a performer compared to the zetec.

for all intents and purposes the duratec line IS the MZR line, just depends on whether you ask a ford guy or a mazda guy.

THe ZVH block (zetec) is actually an evolution of the CVH family as far as I know (SPIs)...

[biker16]

the ZEtec E is all ford has nothing to do with mazda.

the "Global inline" is a ford/mazda colaboration with mazda leading engineering, ford finaced the project which included 4 plants and cost 2 billion dollars.

the ZEtec is relative of the old CVH motors which lead to the SPI.

They are not Mazda designed. They are Ford designed with input from Mazda and Cosworth (the new Duratech 2.0-2.3 family of engines being use by both manufacturers)

[zedexthree]

Zetec is FORD Europe designed engine. It has no relationship with Mazda.

The new FORD engines that are called Duratec 2.0 and 2.3L are Mazda designed.
