It's real according to all the insiders. It wasn't ready for the 2010 mustang so they either had to release the new stang with the old engines or delay the new body styling and interior for another year. It also helps with quality - only changing part of the vehicle each time.

thanks akirby for the info. i read in automobile mag that the new engine is supposed to be 5.0L and has 400 HP. do you know if that new engine is more fuel efficient with the power bump and is the dual clutch 6sp auto in the picture? thanks.

Highly unlikely that the next engine will be 5L. Even if it is, it's unlikely that it'll have 400HP. There's no chance in the world that it'll have a dual clutch 6-speed auto.
 
As much as I love the Mustang GT, I have to opine Ford doesn't put much effort into it's powertrain or drivetrain. Look at the last year of the SN95 Mustang. The GT only had 60HP more than the V6 while the Cobra had 130HP more than the GT. Look at the '05 - '09 S197. The GT only had 90HP more than the V6 and the GT500 had 200HP more than the GT. Now w/ the '10 model, the GT only has 115HP more than the V6 and the GT500 has 215HP more than the GT.
 
The chasm of HP difference between the GT and Cobra/GT500 is evidence that Ford only wants to give real power to the top Mustang. The GT has always had to soldier on in looks and relative handling alone. Then we always have to take ish from the GM boys about how the Mustang GT can't hang w/ the Z28/SS and that the Cobra/GT500 is priced way too high to be considered the competition, blah, blah, blah...

Read my fingers: the 5.0L is replacing the 4.6L in all products. It will make more power than the 5.4L but should have fuel economy the same or better than the 4.6L. It will be capable of 400 hp NA. There are also rumors that the Ecoboost 3.5L (350 hp) will be available in the Mustang. If so then having a 400 hp 5.0L makes sense. And supposedly the 5.0L will also be boosted to 500 hp. And expect either a 3.5L or 3.7L base V6.
 
The days of Ford powertrains being behind the competition are over.
 
As for the dual clutch tranny - that is a few years away. They're developing the smaller trannies for the Fiesta and other 4 cylinders first. It will be awhile before they have a version to handle that much torque.

I don't really care much about HP rating, thus I don't care much if the new GM pony car has 300 or 400 HP.
And exactly why there is no chance in the world that a 6 sp dual clutch auto can be used? Ford has that tranny I believe.

... It will be capable of 400 hp NA. ...
 
So is the 4.6L. Doesn't mean that it will have 400HP. I'll believe it when I see it w/ my own eyes. Don't get me wrong, I surely do HOPE that they do that, but they have a habit of not delivering on their promises.
 
I wouldn't exactly say the days of them being behind the competition are over. The 2010 Camaro is clear evidence of that! The base Camaro has nearly as much HP as the Mustang GT! And I doubt the 5L (if used) will be boosted to 500HP. For one, that'd be too close to the GT500. For two, if that's supposed to be for the GT500, I don't see them taking a 40HP deficit just to introduce a new engine; not unless they put the GT500 on a crash diet.

Ford also has an IRS in the Explorer and Expedition. Does the Mustang get one? Nope. So just because they have something available doesn't mean they're going to use it in other vehicles in the lineup. (Yes, I know a truck IRS isn't likely going to retrofit to the Mustang. Don't go there! )

You believe wrong. The ONLY dual clutch auto tranny (Ford calls it Powershift) available is in the Euro Fiesta and that's the only one we'll see for the next year at least and it's very torque limited. Development of powershifts with higher torque capacity is 2-3 years away. They're doing it but it will take time.

The 4.6L is NOT capable of 400 hp naturally aspirated in a normal high volume production engine. And the 5.0L might not be 400 hp in a mustang but it will be close. These are the engine choices:
 
3.5L or 3.7L V6 - 265-280 hp (given the mustang's 400 lb weight advantage this will be dead even with the Camaro V6 - at worst)
 
Ecoboost 3.5L - 350 hp
 
5.0L V8 - 400 hp
 
6.2L V8 - 450 hp
 
Ecoboost 5.0L V8 - 500 hp?
 
The Ecoboost 3.5L might become the GT with the 5.0L V8 replacing the GT500. Or the EB 3.5L is a midlevel option and the GT gets the 5.0L V8 and the GT500 gets either a boosted 5.0L or the new 6.2L.
 
The point is by the end of next year Ford will have updated all of their old engines within the last 3 years, and most of the transmissions. The old 4.0L, 3.0L, 4.6L and 5.4L engines will be gone or on the way out. And they'll be competitive on both power and fuel economy. Just look at the Fusion for proof of what they can do when they're serious.
 
The Ecoboost 3.5L and 5.0L will also be used in the F150 but will be tuned for low end torque not max hp.

thanks for the info...
 
I like the idea of the Ecoboost, yet I don't like the idea of the turbochargers. According to what I read and experience with turbochargers, you're getting better performance and fuel efficiency in this Ecoboost set up (V6 fuel economy for V8 power), yet with all turbochargers, they would require higher maintenance, and most important, a turbo cool down. Just the turbo cool down itself (my own opinion only) would steer me away from owning another turbo.
And (again my own opinion only) good thing I don't really care for the performance # as long as I don't have the feeling like I'd towing a 10000lb piece of iron down the freeway while I'm driving, I'd be ok. So in this case, the current V8 in the stangs is good for me I guess, and the 3.7L in the MKS is plenty of power already.
