the current 5.8L is likely on borrowed time seeing that the 5.4L architecture is just about phased out of production as far as I can tell.

A lot of people seem to be hoping and leaning on an ecoboost 5.0L, I still feel like this is a stretch, but anything is possible. I wouldn't doubt SVT could match the 5.8L with simply a supercharged direct injected 5.0L Coyote either..

Another choice that hasn't seem to be mentioned in conversations I've seen would be the 6.2L BOSS engine, it may have been developed as a truck engine, but it has shown a lot of performance potential. After all, the 5.4L was developed as the truck variant of the 4.6L. Aftermarket bolt on superchargers are pushing 600hp easily out of the stock truck engines, SVT dropping forged internals in one and turning up the boost dial like they did with the 5.8L almost sounds too easy..

There are two things that I can see that could get in the way,
A:The engine is externally larger and may not fit, looking into this..
B:It uses a cast iron block

maybe SVT could coerce production of 6.2L aluminum blocks, which could trickle into the trucks, giving the Super Duty and Raptor a little weight off their shoulders...

anyone else on board?

 

No. The 6.2 was scrapped for Mustang duty long ago. It's a huge step backwards, especially with the new car's global aspirations.

 

Neeeeeeeeeeeeever gonna happen.

I'm sure the engine developers are beavering away on something special though.

 

after considering it a while it does seem like more of a longshot.

there's still plenty of time for a 2016 model development.

think they might just stick to the tried and true twin screw on a coyote?

 

When was the last time SVT used anything that was based on the V8 in the GT?

 

It's going to be a Coyote variant, no reason to go up to a heavier engine architecture where the current one has so much untapped potential still there.

 

I have to think they are going to go with a twin turbo 5.0 at some point, with all the knowledge the engineers have gained from the ecoboost program it makes sense for them to take the next step. Considering down the road it makes sense that the 5.0 will be replaced with a smaller displacement turbo v8 then starting work with the 5.0 would add value to a future program. BMW and Audi get 500-600 hp out of twin turbo 4.0 and 4.4 v8s. I think That's going to be the future of volume performance v8s down the road.

 

Maybe at some point an engine built off the Coyote architecture will find its way under the hood of an SVT-badged Mustang, but I don't think it'll be anytime soon.

 

A tall deck motor would be nice provided the S550 can house it, its probably a given that the next gen car will be FI in some form (I'm betting supercharged provided they can hit fuel mileage goals as power isn't really an issue unless Camaro goes ballistic) so not alot has to be done cylinder head wise.

Would hate to see the next gen Mustang roll back the displacement on the GT just so the GT500 could use the 5.0

Other manufacturers may be using smaller displacements to get the same power but typically such engines have to work harder in order to reach the same power in combination with other technologies which makes them more expensive to mod as well as being less responsive to such mods.

Then as now, there is no replacement for displacement when it comes to cheap power.

 

I think its too early to tell, lots of unanswered questions this far out.

 

I would guess it will be loosly based on the coyote.

Reinforced block that will be bored and stroked, higher flowing heads(either ported coyote heads or new revision of heads with higher flow), more radical cams, forged rotating assembly, either supercharger or twin turbo.

 

I'd say the 1995 Cobra, I think it was just different heads and intake...

I think Ford should just keep the 5.8 but refine it for better fuel efficiency. It seriously doesn't need anymore power. Perhaps direct injection, lighter materials will bump up mpgs and maybe bump hp by 5-10 or so....

 

I was about to say the same thing. I dont think Ford would just get rid of the 5.8 that fast the next gen GT500 might even get a 8 speed manual/auto trans for better use of all that power and maybe better fuel economy.

 

Ever hear of the 03-04 Cobra?....

 

I'd be interested to see if the current 5.8 will fit in the new engine bay that's been spotted. It very well could go the same way as the 03-04 Cobra engine.

 

Doesn't look like it would, at least not without a huge cowl hood...

 

S550's engine bay looks like it'll be a tight fit (look how the framerails....if that's what they're call, curve inwards on this mule, making the Coyote a tight fit!)

 

For comparison sake. Here are pictures of the 2013 Engine bay of GT and GT500.

The new rails won't make any difference. The car still has room between the shock towers to fit the 5.8L. Also looks like the 2015 still has plenty of height clearance for e supercharger.





Since the new framerails intrude on the intake tube they should move the coolant tanks inward and then make a SC plenum with a 2 smaller throttle body, one on each side and have twin airfilters that are smaller than the single current one.

Of course plumbing would be different than this one but the idea is here.

 

I would surmise that the future GT500 mill would most likely be some varient/development of the Coyote 5.0, perhaps a tall deck version with either super or turbo charging and all the rest of todays technical doodads (DI, VVT, etc.).

The 6.2 is relatively a big, heavy duty meant more for low rpm heavy-duty truck use rather than real high-efficiency, hi-po duty.

 

The two engine bays may look similar in size, but until we get some empirical data to compare them, we really don't know. With the new packaging seen in the photos posted, it's really hard to tell what might or might not fit, aside from the Coyote.
