Which engine for 2015 Mustang?

[S550Boss]

I'd like the think the GT would have the equivalent balance of power/handling to today's Boss.

I believe the S550 GT will be a lot better handler than the current Boss, which with it's solid rear axle has all kinds of problems and is not the genius work of suspension tuning that initial magazine articles made it out to be.
As for the Boss engine, it's only a 24 HP difference (for a lot of hardware changes), and a 10 lb-ft deficit, above the GT engine.
The next GT has to make up this HP difference to attempt to meet the LT1 @ 450 HP, which BTW also has 70 lb-ft more than the current Boss. And since the cars will weigh the same (and the Camaro maybe even lighter), the Mustang is in trouble.

I'm simply referring to the TTV6 in a Mustang application. Same with the TTV8. Remember the tooling trial cars with "TT" on them that everyone freaked about? People jump on this rumor time and time again and there has been absolutely NO credible evidence other than a few speculative rumors from magazines that have mixed track records.

Also, everyone expects that Ford has to top the GT500 with the S550 iteration of the SVT vehicle. I'm sure they're hard at work right now, but following on the heels of Trinity, those are mighty big shoes to fill. Maybe they'll pull a "Raptor", go back to the drawing board, and come out with something that's a bit of a departure from what we expect. Who knows. If the car drops weight but can more effectively use it, is that a bad thing? Seems to me the ZL1 did wonders with an 82hp deficit.

As you said, we don't really know, but I also don't think it's feasible to expect continued increases in power, especially given the upcoming CAFE regulations, increased emphasis on safety, and more standard safety features. Those all cost money and add weight, and are unavoidable from an engineering perspective. That said, don't be shocked if the only turbo we see is on the rumored 2.3 I4...

Considering the "TT" is located on the same place as the mass production (MP) numbers you'd think people would've known it referred to something else.

Yes, there has been no credible evidence of a TTV8 in a Mustang. It's been a lot of speculation combined with some wishful thinking, and people trying to figure out the dilemma of what engine goes into the next GT500 given what we know. It's a fair point about weight and balance. Ford has shown a real desire to compete on HP with the GT500, but I believe those days are coming to an end and the new race will the the weight and efficiency one. With the lighter Alpha and stricter regulations forthcoming, the 662HP Trinity may be known as the last iteration of the high displacement monster HP engines for the Mustang.

That said, I think the turbo trend is here to stay. I won't speculate as to which (if any) new engines we will see in the coming years, but it's clear to me that Ford is not going to stop at the 2.3L inline 4.

I think the issue with making it more Boss-like is that it might handcuff Ford into offering the GT500 as the only special edition. Ford found itself with a problem by making the Boss 302 almost too good. Yea it's more balanced and less about "brute" straight line performance. Remember this article about the SVT team's development of the Trinity?

If they start thinking more agile performer than blind HP, I'm not sure how much room that leaves for another Boss or Cobra etc.​

I just realy can't understand that they would put much time, effort and money into developing an engine they use for only 2 years for the gt500. What's the point? They already blew the ZL1 engine out of the sky.

This might be a case where the engineering team and the bean counters yelled and screamed at each other and in the end the math boys lost. This wouldnt be the first time Ford has done this.

They essentially did the same thing with the 11-12 aluminum block 5.4. Yes, it's the same basic design, but there are necessary hours of engineering that went into making sure the design worked. It's not unheard of.

 

[Prodigy]

What about reverting back to the condor engine with the next GT500? With the weight savings of that engine and a lighter frame, it could make up for any loss in power?

The Trinity was loosely based on the Condor block IIRC, so you wouldn't save much in terms of weight.

 

[NRMStand]

Yea theyre going to have to do better than that (just using the condor) and no one knows whether a SC 5.4 would fit either. The next engine for the gt500 is still possibly 3-4 years away from being in the hands of customers so they have time on their hands. I think even a slight redesign of the hood clearance at that point is possible so what we see in 2015 may not be necessarily be decisive of what they can or will do in 2017....

 

[S550Boss]

This whole business about "fit" and "tighter engine bay" isn't at all accurate. The distance between the strut towers is identical, and the length of the engine bay is identical.

It's only in the corners ahead of the engine that the fit is tighter. The swept-back headlamps cut the corners of the engine bay, requiring a different fuse box on the left and an entirely different air cleaner on the right (an unfortunate choice, because it precludes a twin intake for far better breathing - as shown here: http://www.drivingenthusiast.net/se...s-showcars/frpp_fr500/engine/fr500_engine.htm). But the length and width space for the engine is identical.

As for height, it's just a matter of adding clearance thru the hood. That's all the current car does too. Armchair Engineer rumors of a "lower hood" in the S550 doesn't mean much either because the height of the radiator support in the S550 is all but identical. The car may have a longer nose and dip down a bit further, but at this measurement point it's identical to the current car.

As for any differences between 'Trinity" and "Condor" - as over-hyped marketing names as the "Terminator" was - from a size standpoint there isn't anything except the very slight height difference of the S/C. So who cares. This is the same engine family as has been around since 1992, and it's all but dead. It might be around for another year or two, but after that it's dead. Without the independently variable cam timing of the Coyote, it's got no future (and also can't get other technology coming in the longer term, such as variable valve lift which is an emissions, economy and performance improvement). And it won't get any of that, the engineering expense is pointless when you already have the all-around far-better Coyote - which was and is mostly paid for by the F-150 development budget (showing it first in a Mustang was solely marketing - it is and always was a truck engine first).

What's needed is another spy picture, this time with the proper production engine under the hood. Whatever that hose was that broke in the mule several months ago, it gave us the opportunity to get a look at the structure of the car. We need that again, and hopefully way before the announced next year.

 

[fastback69]

By the time the gt500 is out on the new platform, the trinity/condor is going to be even longer in the tooth than it is now. No way that by 2018 and beyond they are still using that line of engine so to me it doesnt make sense to use it for the next gt500 for just one more year (by MY2017 I would think) and then have to switch powertrains the very next year.

 

[Twin Turbo]

The next engine for the gt500 is still possibly 3-4 years away from being in the hands of customers .

If the next-gen SVT isn't a '16MY, I'm going to be disappointed.

I don't think Ford can wait too long for their next SE. The '15MY introduction will keep us all content with the various "standard" models, but we're going to need something to keep up with the Z/28 and rumoured supercharged Challenger once the S197 GT500 is no longer available.

 

[NRMStand]

I will be disappointed, but not surprised. I could be wrong on this, but I think the gt500 on the s197 platform was released 2 years after (in '07) the platform debut. If so, theyve done it before.

From a financial standpoint I doubt it will affect Ford too much as the Z28 will not be sold in large numbers and will be a very limited production. But yea, from an image and competitive POV, it'll be a big hole. What they could do is at least release another SVT model before then, maybe in '16, which I'm personally way more interested in than the GT500.

 

[Mechanic]

If the rumors hold true, we'll have at least a turbo 4-cylinder, a v6 and a v8 (DI?) and maybe even others? Curious what everyone plans to get here if these are our options. I think it's roughly 50/50 sales of v6 and v8 for Mustangs if you add all the other editions like the Shelby, Boss, GT500.

I'm wavering between the v6 and the turbo4 which I think is going to be one really fun drive. Seems like we have mostly 5.0 guys which is no surprise, but anyone gonna be swayed by the ecoboost?

I might look into the 4 cylinder. I won't be able to afford much right away after the car itself so it depends what they price it at and what kind of HP the stock tune gets. You guys think it'll be a big increase in price over the base engine?

Couple of grand maybe?

From what I understand the 5.8 didnt really take that much re engineering. Took the 5.4L, increase bore size, increase compression ratio slightly and top it with a more efficient S/C.
