Anyway, I'm smiling big because I think by now that $6 million in engine development for the original Duratec has definitely paid off. My lust is based on the numbers. Let's see, an extra 1.2 liters of displacement, 135 more HP, 115 more ft/lbs of torque, 3 seconds faster to 60... ...and the same gas mileage... ...in a car that weighs about 500 lbs more.

Like I said... I want a bolt on hardtop 3.7L 2012 MX5 Miata with the six speed, big brakes and lightweight alloys with grippy tires... and a warranty ;)

The 3.7L, 5L and 5.4L blocks are aluminum.

Nice to see that Motor Trend pays attention. Oops- they don't The 3.5/3.7 in a unique architecture to the 3.0l Duratec. Maybe the same name, but totally different engine family.

(on a side note- much of the development on the Duratec was to fix what Porsche Engineering didn't get right..... P = over rated, much like most contract engineering companies).

But you are right, the 2.5/3.0 shares nothing with the Mazda 1.8/2.5l V6. Not even close to the same.

Just wanted to get that right.

i had a 2011 mustang convertible rental in san diego for a weekend not too long ago, and was very impressed. it had plenty of power, rode nice, except when the live axle got wobbled by some railroad tracks - the sworn enemy of any live axle rear end, no matter how sorted. the car handled nice, and was just the ticket for a weekend in socal. only $8/per day more for the upgrade, btw.

this might make the earlier 4.6 GTs drop in price pretty quick-like too, no?

Do the 2.5/3.0 Duratec and 3.5/3.7 Duratec share a bellhousing pattern, or is that new as well?

Different, but there is a 3.0 Duratec that will bolt to the new 6F trans that the 3.5 was designed for.

at least Ford is consistently inconsistent with engine platforms. I guess that how some crazy swap can happen...

Well, you'll see a strong reduction in available powertrains soon.

The current 3.0 does bolt up, but that starts with the 2010 Fusion/Escape, but not earlier, and not to a manual trans... (at least FWD/AWD)

How long will this latest hi-tech wonder last? Most of these small displacement hi-output engines seem to have a short life span (120K or so) before expensive repairs set in. ...sigh...I miss pushrods....

Long enough so that you can buy a used one....

I'm thinking that when a few of them get into the junkyards it will make a good Locost donor. Could use spindles, motor and much more.

at the moment, unobtanium.

Only way to get it is in the mustang. Some hot rodders are drooling over the engine since it is so capable, just no wrecked cars yet. Ford is thinking about selling it via crate, but will only happen when production is in full swing and not taking from the mustang.

The funny thing is that 90% of potential buyers looking at a V6 mustang will also have a camry or accord on their list of possible next cars.

That was said of the "old" V-6 Mustang, with market research to back it up.

If they keep coming, more power to Ford, but I think this version will attract more enthusiasts, as well. The only thing I haven't analyzed yet is the real tradeoff between the V-6 and the V-8. You can easily option a V-6 up into V-8 territory. What's the real weight/mpg penalty of the larger engine?

Thanks for the correction. That's why I cited MT. I knew there had been some confusing branding with "Duratec."

As for Ford "fixing" the prototype, I'm not so sure about that. I mean, take it for what it's worth, but word I have is that Porsche built the engine precisely to Ford spec, but changes in the packaging (i.e., engine bay dimensions) meant Ford had to make significant changes. The P-engine was a couple inches longer, overall, with fairly large airboxes in the intake manifold. Ford had to shorten the engine to fit it in the bay, and shrink the intake setup to fit it under the hood, which, IIRC, necessitated the two-stage intake (and robbed us of quite a few ponies in the process.)

But, hey, I wasn't there. It's all just stuff I heard on the intarweb, and I'm sure the correct answer depends on who you ask.

What is going on at Ford is Alan Mulally. The man save Boeing and is an engineer by trade. He knows what works and what doesn't I have so much faith in him that I, Moparman, purchased Ford common stock earlier this year.

I'm embarrased that I previously knew nothing of the man. I just read the Wikipedia post on him, and wow! He really seems to be a hero. That's one exec I won't begrudge his 7-figure sallary.

I saw something that said the F150 is now going to get this engine as the base engine, detuned slightly and hoping for 25mpg.
