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.
