Ford didn't change the engines on anything, Mazda changed the Ford engines to suit their purposes.

The MZR2.0 And MZR2.3 for the Mazda3 are indeed made in JPN.

Sorry, but I'm still confused.....are the engines Ford engines or not? I was under the impression that the 2.3 was a Mazda engine from start to finish. Please clarify.

hmmm

I don't know who designed the engine, but my sticker says that 90% of the car was made in Japan, and final assembly was in Hiroshima.

previous threads indicate that ford is using similar engine components in the Focus. Also, I believe that the chasis will be shared not only with the Focus, but with the next Volvo S40 as well.

I was VERY skeptical about buying a product associated with Ford, I have had two Ford Pickups (still own a 95 Ranger) and the accronym "Found on Road Dead" is VERY close to the truth.

After a few days of research, I believe that Mazda still has enough independence and japanese strength to make this car reliable.

Mazda designed all MZR 4_inline engines, even for the block. Though they uses the Ford technology (Castworth) for casting process and have to build the new plant for that. The engine supposes to be flexible, i.e., Mazda/Ford/Volvo can build with specific perepheric components. Both 2.0 and 2.3L are 100% Mazda design.

As bloung said, they use Ford technology including the block.....
That's not what he said. He said Mazda designed the engine even the block. The collaborating company; now a division of Ford, was Cosworth Engineering. They are an old and highly experienced company who have worked with many major players in racing and production pieces. Their work includes Formula1 engines and some of the block casting technology from this area was utilised and improved upon by mazda according to Automotive News.[/

Is Cosworth Engineering a European Company? I know there was a sweet model on the old European Ford line-up that's called the Escort Cosworth. It was Ford's version of the Rally Car I think. Does that Cosworth have anything to deal with Cosworth Engineering?

Cosworth is like Ralliart is to Mitsubishi.

I believe Cosworth Engineering is the R&D department of Cosworth Racing.

Also known as Cozzie.

Cosworth Technology Ltd is an England company. The Cosworth casting process is invented by them. I know the Ford Sierra Cosworth (size wise, the Sierra is like the Mazda6, and Escort is like the 3). They also build Formula 1 engines.

That's nice to know. I have no doubt about the quality of Cosworth product. This engine should be a good product as well with the Cosworth Technology

So .. do we have a conclusion that the engine is designed and manufactured in Japan? And it only uses some of the manufacturing processes such as casting from Ford?

I have another question. Someone mention the MZR engine. I've read somewhere that the MZR engine is the one with continuous variable valve timing technology similar to the i-VTEC of Honda. So, is it a MZR engine or a simple variable valve timing engine on our 3's? I think it is not a MZR engine because it would be much more expensive.

Ford specifically gave Mazda the responsibility of designing the 4-cylinder Duratec engines to be used across all Ford devisions. Design goals were reliability, smooth operation, and high efficiency. I remember reading in an Automotive News article a few years ago that the engine was supposed to be 10% more efficient than most engines in its class or something along those lines. I'm sure not seeing this in my 2.3L 3, but it is a nice engine, and I like the fact that it has a timing chain instead of a belt.

In designing the second gen Focus platform, in particular, Mazda was given the responsibility of engine development, Ford was supposed to be doing chassis/suspension design, and Volvo the safety aspects. Each of the three cars sharing the platform at this time (Mazda3, Volvo S40, and European/world market second gen Focus) have their own division customizations to the handling to give them their own brand feel.

From Bruno Luong:

The Mazda3 2.3l (and 2.0l for that matter) are assembled at Mazda's Hiroshima Japan engine plant.

Being part of the Ford's global 4-cylinder engine family, there is more than one plant assembling this family of engines. Ford's Chihuahua Mexico plant indeed assembles this engine, but only for N. American-assembled vehicles (e.g. the N. American Mazda6 2.3l, Focus, and Ranger). And from a business perspective, this makes total sense. Oh yeah, the Mexican plant began assembling this family of engines even before Mazda's Japanese plant, so those Mazda6 owners have nothing to worry about.

^^^ BTW this topic pre-dates most of your links (so if you were implying it is a re-post). take a look at the year.

It's a Ford/Mazda (Focus block and internals with various Mazda-specific parts, notably the S-VT) design, made in Japan for the 3.

The 3.0L Duratec V6 in the Mazda 6 is an original Ford engine, and a great one at that. It was initially introduced in the Taurus and Sable in 1996. Mom's 1996 Sable LS has 160,000 miles on it and that engine still runs great, even after the beating I gave it back in my High School days. (I couldn't help the fun in embarrassing ricers by beating them in your mom's station wagon:D). I hope the 4 cylinder Duratecs are as smooth and reliable.
