UPDATE 02/11/2014: Be sure to check out our 2015 Mustang information page containing up-to-date information on everything we know, and will update it as more information is released.
Thanks to some skilled spy shots released by Autoblog, we now know more details about the 2015 Mustang GT350 that is rumored to be unveiled at the 2014 New York Auto Show later this spring. While we know a lot of details about the 3.7L V6, the 2.3L EcoBoost I4, and the classic 5.0L V8, not much is known about the motor in the upcoming GT350. These photos indicated that forced-induction is on the table, possibly killing the rumors that the GT350 would be a naturally-aspirated engine.
The 5.0L GT Mustang has heat extractors on the hood. These vents, near the top of the hood, are designed to vent heat straight out of the vehicle when the engine gets hot. These spy photos indicate that there are hood scoops on the hood. Scoops would be used to push cool air into the engine compartment, and is typically used in a turbo or supercharger application. Since Ford is all-in on EcoBoost, it is unlikely that a high-output Mustang engine would be supercharged.
Rumors of a big motor, codenamed Voodoo, have been floating around by some of our sources, but nothing has been verified. Ford indicated last fall at the announcement of the automated Ford Fusion that there will be one more new EcoBoost engine announcement coming soon. That engine ended up being the 2.7L V6 EcoBoost that will be in the new F-150. That would indicate an all-motor Mustang, which was previously speculated. But that nostriled hood really changes things up.
If the engine is forced-induction, we would expect it to make at least 650hp. The last Shelby GT500 made 662hp. However, the new Mustang is allegedly 200lbs lighter than the previous version, making the vehicle faster per horsepower the engine puts out.
We do know, for a fact, that there will be a Shelby Mustang Coupe and Convertible thanks to an exclusive leak we broke a few weeks back. Also, the 2014 New York Auto Show makes a lot of sense to unveil the vehicle, as it would be the 50th anniversary of the Mustang. It would be logical to have a blowout announcement there.
