I am uncertain we will ever see DI in a pushrod V8 application as the benefits are likely to be far too small to justify the costs. And even if GM decides to go ahead with DI anyway, I'll be surprised if they can muster the funds to do so by 2012.

I've seen that, and all that accomplishes is to further cloud the issue of whether DI is beneficial enough on a pushrod V8 to even be bothered with. GM knows, but we don't and the info provided does nothing to help us. Why do I say that? Simple, DI by itself provides nowhere near that percentage of power improvement on any engine with the exception of forced induction pieces. That means that vast the majority of the power gain cited in that article is from a change other than DI, which in turn means that we have no idea how much of the power gain cited...if any of it....is actually from DI.

As I said before, if the DI versions of the LS series V8 engines were as magical as was claimed, it would already be here shoring up sales of full size trucks and improving fuel economy averages in the process. You aren't hearing much about them now for a reason, and my guess is that reason is disappointing performance in producable trim. Ford already figureD this out and they were thinking of implementing the system on a DOHC platform with three stage VVT on the intake and achaust sides of the valvetrain, meaning they should have been able to realize far more benefit than GM can plausibly hope for given the more limited valvetrain articulation the cam in block, pushrod V8 design is saddled with.

In naturally aspirated applications DI is a very, very expensive way to get a ten percent improvement in power on a very good day, and an even lesser improvement in economy (if any meaningful improvement in fuel economy is realized at all) at the expense of increased nox emissions. It isn't worth it.

Wasn't the Cobra just a limited edition of the Mustang? I don't understand if IRS is so irrelevant in the Mustang why does the Camaro have it?

BTW, saw my first Camaro on a Chevy lot today. It was in red and the car was stunning.

All new mustang will be out for 2014 model year. they average a complete redesign every 10 years.

basically there will be 3 engine choices instead of 2. teh 5.0 which will be over 400hp.

the ecoboost v6 for MPG enthusiast at 355hp. likely cost around 28k, the current base GT price.

and the base 4.0 V6 will probably get a boost of somekind to 275 hp and still cost around 21k ish.

i can almost gurantee thats the direction they are going.

the 4.0 will not get 275, not even close.

if the 4.0 sticks around, it MIGHT get an increase to about 225-240, but even then, wouldnt be suprised to see the 210hp rating stick around.

the 3.5 will likely replace the 4.0

they cant get rid of the 4.0 because they need an engine to keep one model in the 21k price range. i dont think they can do that with ecoboost. if they can thats awesome, but id be surprised

Is the Ecoboost an Aliminum block engine?

Yes it is.

"The EcoBoost-branded aluminum engines use direct gasoline-injection technology and twin turbochargers. The combination reduces the amount of gasoline burned by 20 percent compared with a conventional gas engine while also boosting horsepower and torque to levels typically found on much larger engines."
