2010 Shelby GT500 - Click above for high-res image gallery

Here's one we've been hearing rumors about for quite a while – an EcoBoosted V8 Mustang. Put another way, a twin-turbo, direct-injected, V8 Shelby GT500. The first rumor we heard was about a twin-turbo 50th Anniversary Edition 2014 1/2 Mustang, which would be the very definition of the word "Sweet!" We asked about this mythical car point blank to several fairly high-ranking Ford execs, only to be stared back at in silence. Although one dude – who shall remain nameless – did crack a knowing smile and asked, "Who told you that?"

Regardless of our shoddy scooping, The Detroit Bureau's Paul Eisenstein is now claiming that according to several unnamed sources, Ford is considering such a beast of an engine. Good idea? We think so. Not that there's much wrong with the GT500's current supercharged 5.4-liter monster, especially as it's pretty underrated at 540 hp. But it is a little long in the tooth being essentially a ten-year-old Ford GT power plant with a couple of changes. Not that current GT500 owners care, but at full clip, the Shelby gets... how to put this kindly... abso-fricking-lutely abysmal mileage.

We also know that while the current Taurus SHO's EcoBoost V6 makes an impressive 365 ponies, 600 horsepower is there for the asking (a little tuning, sure, but the engine can do it). With that in mind, can you even imagine the levels of sound and fury a twin-turbo V8 could unleash? Eisenstein doesn't mention it, but Ford wouldn't be slapping turbos on the old 5.4-liter or the older 4.6-liter modular engine. The EcoBoosting would be applied to the new 5.0-liter Coyote V8. When General Motors introduced LS3 V8 a few years back, it was noted by many that the intake manifold looked suspiciously like it was designed with forced induction in mind. We've heard similar rumors about the Coyote.

      Wonder what the dealer markup on a 50th anniv shelby would be . . .
      • 5 Years Ago
      Why do you say that?
      • 5 Years Ago
      Well there is a boosted version of the current Shelby 5.4L V8 making 725 Horsepower so you do the math. Conservatively, you're probably looking at least 600HP and realistically all the way up to 800HP or more. Holy Hannah, it looks like the Hot Mustangs may soon be Corvette hunting.
      The 5.0L Coyote should be relatively the same size as current 4.6L with an aluminum block to boot so weight should not be too much of an issue. If they manage to keep the weight in check, the new Mustangs with the new engines are going to be really tough to beat.
      • 5 Years Ago
      Don't forget that the 5.0 Coyote is also slated to replace the 5.4L modular in the F150 which negates any concerns about developing an all new engine for limited use in a Mustang. They sell a bunch of F150s in case you hadn't noticed.
      I have no idea if a twin turbo Coyote will ever show up in a Mustang but it sure would be sweet. And I don't think there would be any need for concern about low rpm torque if the 3.5L EcoBoost is any example. That engine pulls a flat 350 ft lbs from 1500 rpm to over 5200 rpm. Assuming the Coyote would also get DI for a twin turbo application you could extrapolate that if the 3.5L makes 100 ft lb per liter then the 5.0L should make 500 ft lbs at a similarly low rpm. It sure would be nice to have AWD to harness that kind of twist...

      Wow if they keep the GT500's ~$50-60k pricebut pump out 600+ horsepower they could have a ZR1 killer.
        • 5 Years Ago
        ZR1 killer? No. Too heavy and the center of gravity is too high.
        • 5 Years Ago
        Exactly what I said in my blog (http://hereshowiwoulddoit.blogspot.com/2008/05/ford.html) back in May '08. Mustang Pony would have a 2.5L ecoBoost 4cyl putting out 240-250 hp, in homage to the awesome LX 5.0s of the 80s, the Mustang LX would have the 3.5L ecoBoost V6 rated at 350-360 hp, the standard Mustang GT would have a D.I. 5.0L V8 rated at approx. 400 hp, the "special edition" 'Stangs (GT/CS, Boss, Bullitt, etc.) would have either a bored out 5.8L (my nod to heritage) or a properly tuned Coyote V8 putting out 440-450 hp, and then an ecoBoost V8 (again for heritage, I picked a bored out 7.0L, 429 c.i.) rated at 600 hp for the GT500.

        Zr1 killer in what aspect? Cause as much as I love the idea of an Ecoboosted mustang, I just dont see it coming anywhere close to the track performance of a Zr1. Your comparing an apple to an orange. dont just see "American" and "Big Power" and reach for that connection. there is alot more to it.
      • 5 Years Ago
      They should call it, "The Monsters" or something exciting like that lol. Wow that sounds nice. Oh wait, we have to think of the environment.... right?
      • 5 Years Ago
      YES! PLEASE GOD YES!

      TT v8 would be the next best thing since the 2jz, sr20det, and whatever else....
      • 5 Years Ago
      Ok.. so hmm.. how can I put this. They say the EcoBoost 4 has the power of a 6 yet the mileage of a 4. The EcoBoost 6 has the power of a 8 but the mileage of a 6. So in continuing the trend one could assume that the EcoBoost 8 will have the power of a 10 with the mileage of a 8. Am I wrong in this thinking?
      If this does happen then wow... not a huge 'stang fan but with that much power and if anything maybe for a reasonable price I may have to start looking at the 'stang.

        "Yeah the Tau V8 makes THREE more hp then the SHO and the Tau V8 requires premium while IIRC the Ecoboost does not.

        But the Genesis is rwd and weighs 200 lbs less then the SHO. If it had AWD it would weigh more the SHO and get much less mpg. "

        Umm...WRONG. The Tau V8 makes 375 HP.....the Lincoln rebadge of the Taurus makes 355. Only on PREMIUM does the SHOW make 365HP.

        And the Genesis does not need AWD because Hyundai knows how to build a desirable luxury car...........unlike Lincoln. Ford's AWD system is the biggest piece of garbage on the planet. The limp-wristed system is 100% FWD under normal driving conditions. Who would want that. And look what it's gotten Ford.........the most unreliable rating from Consumer Reports for the Lincoln Taurus.

        And if the Genesis is heavier with AWD...well...Hyundai built a more solid car.

        Ford's vehicle line-up is the most undesirable, bland, boring, ugly bunch of appliances on the road today. They are full of compromises. Ford really has become the Toyota of American auto makers.

        Don't waste your breath, Matt is completely hung up on the fact that Hyundai has a V8 in the mid-sized Genesis (that is slower and doesn't have AWD, but it has more HP, that's all that matters right?) that gets the same mileage as the Full-sized AWD SHO.
        • 5 Years Ago
        Ford lies.

        The Egoboost V6 does NOT have V8 power with V6 Economy.

        Hyundai makes a 4.6L V8 with more power than the egoboost 3.5...and it gets the same mileage as the Taurus SHOW/MKS.
        • 5 Years Ago

      EcoBoost V8??? Dear Lord, that will be powerful, and efficient. :D
      • 5 Years Ago
      Twin-turbo GT500? Holy **** on a **** sandwich with **** on top! And a side helping of *****!
      • 5 Years Ago
      Can't wait to see how it works in my Fiesta!

      V8 fuel efficiency with V10 power?
        • 5 Years Ago
        @groundZ
        If Ford is smart when they start production they should run a promo ad that states something like that maybe a tag line of "Living Oxymoron".
        • 5 Years Ago
        I know it's all relative, but I giggled at "V8" and "fuel efficiency" being placed so close together.
