We just wrote about the report that General Motors is developing a 3.0-liter twin-turbo V6 to challenge Ford's 3.5-liter EcoBoost V6, and that the GM version might – just maybe, possibly, perhaps – go into the Camaro. Ford, on the other hand, apparently has no immediate plans to put its powerful and frugal turbo V6 into its pony car, the Mustang.

 

Ford's not going to replace the current 3.7 V6 with the Eco-Boost V6 since they would lose that great fuel economy rating.

 

yep, makes sense to me -- the eco-boost is a little more powerful than the 3.7, but a lot less "frugal" on gas

 

I don't want that motor in the Mustang. If it goes in, it will be a test market against the need for a V8. No thanks!

 

The 3.5TT wouldn't appear in the base Mustang anyway.
That thing would spank out well over what it puts out in the AWD combo.
Its also more expensive than the GTs 5L.

Now a I-4T would be a different story.

The 5L has more than enough legs for the time being in its various variations to keep GT buyers happy.
V8s won't be going anywhere anytime soon.

 

Agreed!

 

I totally disagree. The Lincoln MKS is available with a naturally aspirated 3.7 or a 3.5 EcoBoost. The n.a. 3.7 makes 273 hp, while the 3.5 EB makes 355. The fuel economy when comparing AWD version of both is BETTER with the EcoBoost engine. Neither of these engines has Ti-VCT, but I expect they will both get them in another year. The EcoBoost could make substantially more but the engineers have capped it there to preserve the rest of the drivetrain.

With Ti-VCT and tuned properly, I would not be surprised to see an EcoBoost V6 that could make as much horsepower as the new 5.0 AND deliver fuel economy as good as the new 3.7. It would cost more to build than the Coyote, however. As long as the price of gas stays cheap, not many people would pay extra for an EB V6 just so they could get an extra 4-5 mpg with little or no increase in power over as V8. Besides, the majority of Mustang enthusiast think that V8's sound great and any other configuration sounds poor.

For myself, I would prefer an EcoBoost V6 providing it sounded good. We may very well be looking at $4 a gallon or more within a few years.

 

If anyone thinks that Ford wouldn't try to put a Turbo V6 in a Mustang to replace a V8 sometime in the future, just remember the next-generation Mustang that (fortunately) never was: The Ford Probe.

 

Maybe so, I was just comparing the current ecoboost (as used in the Taurus) to the current 3.7 in the Mustang -- the current Mustang gets 19/31 ; the ecoboost Taurus gets 17/25; last time I checked, 19/31 was more than 17/25

 

The ecoboost taurus is 4 wheel drive and is very fat, weighing 4200 lbs., but even at that the ecoboost in the Mustang wouldn't get the 31 MPG the 3.7 will.

Comparing fuel economy ratings of an AWD Taurus to a Mustang does not seem like a valid comparison. That's why I chose the Lincoln MKS. It's one car that is available with an unboosted 3.7 and an EcoBoost 3.5.

 

Until such an engine has been installed and tested, we're all just making educated guesses about the fuel economy of a V6 EcoBoost Mustang. But as I mentioned above, the Lincoln MKS with an EcoBoost 3.5 makes better mileage than the unboosted 3.7 in the same car. The 3.7 in the MKS isn't exactly the same as the one in the Mustang, as it lacks Ti-VCT, but so does the 3.5 EB in the MKS.

I'm just trying to apply logic here, if you can point out my logical error I'm willing to listen.

 

At NO point in that does he say 'no ecoboost 4'
All he states is that 'no we won't go backwards in HP to the question of lower HP Ecboost...'

Fox is making assumptions

 

The other issue with the 3.5L EB is fitting it into the current Mustang engine bay. While the engine may be the same basic size as the new 3.7 and smaller than the Coyote, once you add on the turbos and all their associated plumbing, intercooler, etc. it becomes a much larger package. The Taurus is a FWD platform (modified for AWD on the SHO) with the engine mounted transversely. Keep in mind that the Mustang body is lowered onto the engine/front suspension sub-assembly. Not saying it cannot be done but I imagine there would have to be extensive modifications to the car or the engine packaging or both. The current platform was never designed with a twin-turbo application in mind. I also doubt there would be enough sales to warrant the modifications. Now, 2014 and beyond..that's another story...

 

Been done...

 

I hope not. If Ford drops the V8 out of the Mustang range... they've lost me as a customer.

 

I can see Ford offering an EcoBoost 4 cylinder added to the engines we now have, 3.7L and the 5.0L.

 

Hey, I used to have a Probe GT V6 and it was a great little car -- not a Mustang by any stretch, but a great car in its own right (had to defend my Probey).

That said, I think the Ecoboost V6 could readily be made to generate 5.0 power numbers with greater efficiency and lower emissions. Such a motor might make a great complement to the 5.0 in the lineup but it could never replace it. A Mustang without a V8 is just a dumb idea. Ford tried it once with the Mustang II for a year or so but quickly realized their grievous error and plunked the 302 back in. And, as mentioned, some suits toyed with the idea of a FWD V6 Stang -- the future Probe -- but that quickly got shouted down (of course, we had to soldier on for another 12 years with the creaky Fox chassis as a result).

I think the Ecoboost V6 is always a strong card in their hand, but probably one they won't likely play at least in the near term.

 

if the Ecoboost 4 cylinder is put in the Mustang, i say put it in the base Mustang and call it an LX and market it either above, below, or with the V6. Then again that might spike the price of a V6 Mustang up.....
