    You are right, the Windstar uses the Vulcan engine, not the Duratec. The only minivan with the Duratec is the MPV.

    The new Mazda 6 also offers a higher performance gasoline engine, a 3.0-liter aluminum V-6, optimized for low-friction efficiency and high power and torque output. The 24-valve engine also is equipped with sequential valve timing.


    Powered by the 222-PS / 163 kW (219 HP) V-6 with S-VT, the engine achieves its peak horsepower at 6,250 rpm. Torque output peaks at 273 Nm (202 foot-pounds) at 4,500 rpm.


    "The new V-6 with sequential valve timing gives Mazda 6 uncompromised power and torque," Saruwatari said. "We believe it is the ideal complement to the refined, fun-to-drive nature of the Mazda 6 chassis."


    For maximum fuel efficiency, the new V-6 incorporates friction-fighting features. Roller finger cam followers, with bucket-style tappets, minimize valvetrain friction that could negatively impact fuel efficiency.


    The V-6 also takes advantage of the same air cleaner with variable duct and reduced back-pressure exhaust strategies as the four-cylinder engine range.


    The aluminum cylinder block is manufactured with iron cylinder liners for durability. Four main-bearing caps and two longitudinal stiffening rails are combined in one girdle casting that is bolted to the cylinder block. This girdle has nodular iron-stiffening inserts surrounded by die-cast aluminum.


    A structural cast-aluminum oil pan strengthens the bottom of the block and provides a rigid engine-to-transmission connection.


    Cast aluminum alloy cylinder heads feature a pentroof-shaped combustion chamber that provides a 10.0:1 compression ratio. Intake valves are 33.5 mm in diameter and exhaust valves are 28 mm in diameter for excellent breathing properties.


    The engine's forged steel crankshaft has nine fully machined counterweights. Connecting rods are sinter-forged for fracture-splitting. Pistons are a lightweight design with a graphite and molybdenum coating that minimizes piston skirt-to-cylinder-wall friction.


    A single silent chain - with hydraulic tensioning - drives both camshafts in each cylinder bank. Each tubular steel camshaft is assembled with sintered high-carbon steel lobes.


    The intake manifold is a two-piece composite-plastic design lower component that is integrated with the fuel delivery rail.


    Twin-spray top-feed injectors are supplied by a returnless fuel system and triggered sequentially in synch with each cylinder's intake valve opening. The fuel pump is located in the fuel tank and computer controlled to deliver a robust range of pressures, depending on demand. A rear electronic module commands the pump and monitors fuel-rail temperature to guard against vaporization; if the fuel is warm enough to verge on vapor formation, output pressure is raised to maintain mass flow at the injectors.


    A coil-on-plug ignition system eliminates secondary leads by positioning one coil triggered by the powertrain control module immediately above each spark plug.

    By adding Sequential Valve Timing to the Ford V6 Duratec ...

    So is there a Cosworth Mazda 6 in the future? That would definitely be nice:)

    HOW MUCH IS IT GOING TO COST
  • azstanazstan Member Posts: 74
    DOES IT USE REGULAR UNLEADED GASOLINE?
  • vocusvocus Member Posts: 7,777
    What is with all the yelling in here?

    Prices are not officially released yet, but the car will probably cost a little more than the 626 it replaces.

    A couple of posts above said regular gas can be used in the V6 engine.
  • ickes_mobileickes_mobile Member Posts: 675
    according to Mazda's specs.
  • kenokakenoka Member Posts: 218
    Mazda is using Cosworth's new sand casting process for aluminum blocks. This is the extent of Cosworth's involvement so far.


    This plant has introduced the "Cosworth casting process," which is also used for the peak performance F1 auto-racing engine. This casting process technology has been provided by Ford and Cosworth from England, and then matured and innovated by Mazda-specific technology. Through this, the mass production of quality, lightweight, and compact engines has been attained, and an epoch-making production process, producing at a lower cost than cast iron engines, realized.

    Scroll back a bunch of posts to a link about the demonstrated concept MazdaSpeed 6 - 270+HP, lots of torque and AWD (IIRC). There are links and photos.

    I don;t remember if it was turbocharged or NA.
  • kenokakenoka Member Posts: 218
    Turbo. Definitely turbo. You recalled correctly about the AWD. Can you imagine 276hp and front wheel drive? *shudder*. Don't forget the 6 speed manual tranny.
  • slickdogslickdog Member Posts: 225
    Nice post, chikoo. Good to see some dirty details on the guts instead of the fluff. I'm feeling better about the Duratec all the time, especially since it won't be bolted to a Ford tranny. I'm not really too keen on Fords (new or old), but they have had a few good engines in the past (excepting the 3.8L V-6 of course). I was initially concerned about a lack of new technology in the engine because Ford tends to carry old engine technology longer than other automakers (they were still using distributors on some engines into the '90's!), but it looks like Mazda is taking care of that.

    The 2.5L V-6 in my '00 626 is very well engineered, but both these new 6 engines appear to be even better. Anyone here on the board ever work on a Duratec? How easy are they to work on? The under-hood layout and design of the 2.5L in my 626 make working on it rather painless most of the time. Mazda seems to have good attention to detail in that regard. I can't say that much for the manufacturers of many other FWD cars I've worked on, however (especially domestics). Hopefully the new 6 will be comparable to the 626 in that respect, although I am a bit concerned that the larger Duratec will be a rather tight fit under that sleek looking sheet metal.

    Most pictures of the Mazda6 show the car with Mazda's now typical "five point" chromed front grille (like an open mouth) but some others pictures out there show a different more aggresive style of grille with horizontal "blinds". What's up with that?


    http://www.mazdaatenza.com/images/imggal/pages/yellow3.htm

  • the_big_hthe_big_h Member Posts: 1,583
    that will be available, for that 'performance' aggressive look.

    stock will be the 5 poing grill with the chrome bar across the top.
  • mazdafunmazdafun Member Posts: 2,329
    They're available on any trim level in Japan, I think. You can get matching trim pieces for the interior and the headlamps too, I think.

    I think for NA, they're reserved for the Mazdaspeed version (and aftermarket add-ons available through the select dealerships, of course).
  • alternatoralternator Member Posts: 629
    I think the "horizontal blinds" front look is copycat looking and ugly! The base model look is much cleaner.
  • pda97pda97 Member Posts: 91
    220hp out of a 3.0L V6 running on regular gas is a BIG deal. If not, then it's JUST another 3.0L V6....like everyone else has......with the exception of the new Accord 3.0L V6. That puppy puts out 240hp on regular gas ! Now THAT'S superb engineering !!
  • ashutoshsmashutoshsm Member Posts: 1,007
    This topic has been beaten into the ground already, but someone please explain how tangible, useful and important 20 extra hp is, especially when it is in a heavier car (Altima or Accord).
  • pda97pda97 Member Posts: 91
    OK, I just checked the Mazda site. The recommended fuel for the 6's V6 IS indeed regular unleaded. I'm impressed ! Sign me up for one. The 03 Accord's V6 is still superior though. Unfortunately, it's wrapped in a hideous shell.
  • pda97pda97 Member Posts: 91
    What is it you don't understand ? One 3.0L V6 puts out 240hp vs 220hp for another (of identical displacement). Strictly from an engine design/enginering point of view, which one is superior ??? How do YOU grade an engine ?
  • reward72reward72 Member Posts: 11
    Bragging rights... and probably ignorance.

    No car *needs* more than 150 hp or so. Period. That is more than enough to reach speed limits and pass trucks on the highway. More than that is just for fun... or to compensate for something else!!

    Many people think that only hps make a car fun to drive. It's not, it's the whole experience... It's the handling, the sound of the engine, how it communicates the feeling of the road, how it corners, how it makes you feel the speed... It's not about how fast it can go or how quick it can reach 60, it's how it makes you feel getting there.
  • ashutoshsmashutoshsm Member Posts: 1,007
    No, more hp from an engine of comparable displacement is not necessarily a sign of better design. You need to compare the torque curves and eagerness (insert appropriate tech term) to rev as well.

    And my question was "Why is 20hp more in a heavier (and uglier, but that's personal opinion) vehicle (such as the Accord or Altima) such a big deal?" I merely do not share this silly fascination with larger numebrs that the masses seem to have, when it comes to large numbers in the hp column.

    Drivability is a whole different issue, and in almost all cases, the lack of 20hp (around 8%) in a car over 5% lighter will be impossible to notice, whereas higher torque will make a huge difference, particularly in city driving. Add the amazing handling the 6 offers to the package, and I just don't see the logic behind the hp fanatics' case!
  • ashutoshsmashutoshsm Member Posts: 1,007
    I agree with reward - if I were to buy the Mazda 6, I would ONLY consider the 160hp 4 cylinder Mazda 6i. More than enough, with a much better (I would expect) front-rear weight ratio, and lower overall weight. Although, strangely, the website lists 60/40 as the weight distribution in boh versions.

    I've driven my fair share of large displacement 6 cylinder vehicles - rentals, borrowed cars etc - and none of them has the sprightly feel that 4-cylinder sedans offer!
  • mazda6smazda6s Member Posts: 1,901
    Sure, the Accord V6 makes 20 more HP, but it's at a gazillion freakin RPMs! Who drives around at 5000-6000 RPMs all day? Anyone who has ever driven a Honda 4 OR 6 knows that they are all high RPM engines, and are not blessed with a lot of power or torque at lower RPMs, VTEC or not.
  • the_big_hthe_big_h Member Posts: 1,583
    actually, I am quite impressed with Honda's engine technology, the new 3.0L for the Accord, in addition to more power, also has better gas mileage (EPA 21/30), and runs on regular gas!

    but the body that wrap around this impressive piece of engineering.... um.... eh...... yeah....

    I think we should move this engine discussion over to the comparison board before Pat come around and putting the law down :-)

    If BMW non-M motors were only judged by their peak hp number, then they wouldn't be so sweet.
  • pda97pda97 Member Posts: 91
    Let's see....the 6's V6 is rated 220hp @ 6000 RPM and 192lb-ft @ 5000 RPM. The Accord's V6 is rated at 240hp @ 6250 RPM and 212lb-ft @ 5000 RPM. Now, I hate to sound like one of them "Honda drones", but I will give credit where credit is due. While the Mazda's V6 is very impressive, the Honda V6 is clearly superior !
  • panamaltd2panamaltd2 Member Posts: 162
    The truth of the matter is the Mazda6 is overall superior to the accord plus the Mazda is smaller and most likely lighter so there is your trade off. Also the Mazda6 will undoubtedly have far superior handling than the Accord. Plus Mazda is planning a "hot" 6 that is said to make at least 270 hp. Just giving credit where credit is very overdue.
  • magnetophonemagnetophone Member Posts: 605
    pda97, there are many more factors to whether a car is better, and the engine is only one of them. The Mazda6 could have a creamier engine sound, smoother gear changes (entirely likely), etc. etc. Also, the Mazda6 will be offered with a manual.

    For a true auto enthusiast, the handling, looks, chassis, ride, steering, gearchange, engine, etc. etc. ALL contribute to whether the car is right for them.

    I did not buy my ZX3 because of its engine, I bought it because of all the other reasons which made the car so much fun to drive. As long as the engine doesn't impede on the fun (which it doesn't), it's only one issue to be considered and nothing that can really rule out the purchase.
  • magnetophonemagnetophone Member Posts: 605
    And, being purely subjective, the new Accord looks sort of ugly. The Mazda 6 is gorgeous!
  • pda97pda97 Member Posts: 91
    YES ! I agree with you wholeheartedly with everything you said in posts #1483 & 1484. I'm ONLY talking ENGINE and ENGINE alone ! Let's clear the air right now. Didn't expect this to be another Honda vs. XXXX debate here. Just turned out that way. FYI, I'm gonna avoid the new Accord as if it were the plague just because it's so darn UGLY. I don't know who was responsible for the design of the 6. But give that person(s) a million bucks for me :)
  • ashutoshsmashutoshsm Member Posts: 1,007
    So basically what you're saying is if Mazda had put the Honda V6 under the hood of the Mazda 6s, or conversely, if Honda had had the good sense to wrap the Accord V6 in something like a Mazda exterior design, with handling and other characteristics befitting a non-lemming buyer, then you would have been truly happy.

    But as things stand, you recognize the superior overall value of the Mazda package vis-a-vis the Accord ;)
    ie: The (relatively benign, and harmless, in this case) Ford-ness of the Mazda 6s engine is easily overcome by the vehicle's design, performance and handling! Just what we've been saying all along, just not in so many words! Glad we're on the same page now :-)
  • newcar31newcar31 Member Posts: 3,711
    Is it just me, or has Mazda always been on top of things as far as styling is concerned? I honestly cannot think of any Mazda recently that has had offensive styling. The last 626 wasn't exactly beautiful, but it wasn't ugly either. IMO, the Millenia, 929, RX7, Miata, and Protege are all good looking cars. Can't say the same thing about ANY other Japanese manufacturer. The new 6 looks so good, it's almost inconceivable that it came from a Japanese company. Subarus look weird and Toyota, Honda, and Nissan stylists have been tripping out recently. Mitsubishi makes some good looking cars (trucks are another story), but they are Mitsubishis.
  • adbsadbs Member Posts: 5
    Is the 6 going to be available in a automatic? I only read something about a manual. Also, any idea on price?
  • newcar31newcar31 Member Posts: 3,711
    Of course it is. What company would introduce a car into this segment without an available automatic?
  • maltbmaltb Member Posts: 3,572
    Of course there will be an auto trans. I think most of the people that post on these boards are automotive enthusiasts and prefer a manual trans.

    Still not sure about The_big_h though.
  • vocusvocus Member Posts: 7,777
    Of course the 6 is coming with an automatic, it's a family car for crying out loud! :)

    4-speed with the 4-cylinder engine, 5-speed auto with the V6 from what I have heard.
  • mazda6smazda6s Member Posts: 1,901
    Here's the deal - Honda won't take the chance of turning anyone off with styling, so they take the safe course with generic (boring but not offensive) styling. They know generic people will buy the generic Accord because it's a Honda. Ah yes, like lemmings following each other into the sea. So, why should Honda take any chances when they don't have to? Mazda, on the other hand, has their back against the wall and they're fighting for their survival, so they have to offer something more. That "something more" is what will steal buyers away from Honda, Toyota, and to a lesser extent, Nissan. It worked with the first generation FWD 626 back in the 80s (I owned one), and it will work again. It should be a good show, and I'm going to enjoy it.
  • the_big_hthe_big_h Member Posts: 1,583
    even though i drive an automatic, I am as enthusiastic about cars as any manual-driving fanatics!!!! :-D
  • ashutoshsmashutoshsm Member Posts: 1,007
    ... for the fact that you drive an auto!
    Although, in your defense (and mine too ;) it certainly IS possible to be an enthusiast with an automatic transmission car!
    But I so wish I had a 5 speed! Next time, I guess :0
  • maltbmaltb Member Posts: 3,572

    "Honda won't take the chance of turning anyone off with styling, so they take the safe course with generic (boring but not offensive) styling"

    I agree with that statement 99%. IMO, the new Accord's styling is as offensive as Andrew Dice Clay performing at a Feminist's convention. The styling is definately a turn off. Even if I was fall down drunk, it still wouldn't look good.
  • wishnhigh1wishnhigh1 Member Posts: 363
    Horsepower and torque numbers are pretty meaningless in comparisons. There are certain engines where I would rather have the smaller horsepower numbers because the engine responds so much better. An example would be the VW 1.8T versus the 2.8 V6.

    I think it would be great if magazines would start publishing the integral values of the horsepower curve from about 800 RPM to the peak HP RPM. That would be a very valuable number. Well..at least to me and those who can still remember calculus.
  • csuftitanscsuftitans Member Posts: 215
    Check out this link for Mazdaspeed 6 aka Mazda 6 MPS. Looks like they'll be using the new 2.3L MZR engine, design, enginereed and built by Mazda, plus a turbo off-course. I think they're talking about the 4-cyl model. I still don't get how they can squeezed 280ps (I think about 275HP) out of a 2.3L 4-cyl engine though.


    BTW, they'll show the car at the Paris Auto Show in about three weeks.

    I'm glad to see you give some credit to Mitsubishi on styling, but the dig that it's a Mitsubishi?

    As the owner of a 3 year old Galant V6 I can tell you I've never been happier with the performance and reliability of a car and that includes the Hondas and Toyotas I've owned in the past.

    My car has knock out looks, good performance and has been near trouble free for three years. I recently completed a 1500 mile trip where my 190hp V6 got 32 mpg on the highway with the air conditioning running all the way. If you think a good looking Mitsubishi should be disqualified from consideration for other reasons you might want to think again. This Mitsubishi has been "so dissappointing" to me that I plan on buying the car when it comes off lease in November. I've never condsidered doing that with any other car in the past. Yes, it is a Mitsubishi and that's not a bad thing. The 6 may well get my consideration a year or two out when I decide to sell my Galant, but for now I look forward to continuing to enjoy it.
  • newcar31newcar31 Member Posts: 3,711
    All of my experience with Mitsubishi is anecdotal. I had a buddie with an old Dodge/Mitsu Colt that help up very well and withstood tons of abuse. I also know a guy with a 96' Eclipse Turbo bought new that was a nightmare. Also, after almost 7 years working at oil change joints (through high school and college), I didn't see too many Mitsus with 200,000 miles on them. So I guess there are good ones and bad ones, as with any auto manufacturer. I do like the looks of some of their cars, mainly the sedans.
