Rumormill: Next Ford Shelby GT500 Mustang Could Ship With 800 HP

Earlier in the month, spy photographers captured on camera what could be the next Ford Shelby GT500 Mustang undergoing testing incognito. The sighting brought out a flurry of speculation from the automotive community, and now, we’ve heard tell that the alleged forthcoming super-Stang could pack as much as 800 horsepower under the bonnet.

A Word Of Caution

Rumors heard firsthand from Ford insiders ask to be taken with a grain of salt; those heard secondhand, as is the case here, demand to be met with even more reservation.

That said, the UK’s Autocar is reporting that some sources have suggested the next Shelby GT500 could arrive with a twin-turbocharged V8 engine capable of around 800 peak horsepower. These rumors are likely rooted in a number of different facts – for instance, that the prototype spied earlier this month wore a sticker with the letters “TT” (possibly standing for “twin-turbo”), and that the Dodge Challenger SRT Hellcat and equivalent Charger model have already surpassed the 700-horsepower mark, prompting Ford Performance to up the ante.

Previous rumors have suggested that the next Shelby GT500 Mustang would make do with a twin-turbo V6, much like the new Ford GT supercar, but we here at Ford Authority have a hard time wrapping our minds around the prospect of a V6-powered pony car topping the Mustang totem pole. However, having witnessed the proliferation of Ford’s so-called “EcoBoost” technology into just about every vehicle in the Blue Oval range, including the 2017 Ford F-150 Raptor and the aforementioned GT, the twin-turbo part of the rumor sounds rather reasonable.

It’s possible that the next Shelby GT500 could even boast the automaker’s first-ever EcoBoost V8. Stay tuned as we keep an ear out for more intel.
