The internet can't decide if it's a twin-turbo'd 5.0-liter V8 , or a supercharged 5.2L pulled from the GT350 hiding under the hood, but wouldn't Dodge and GM love to know. There isn't even a discernable hood bulge to lead us down a wild path of speculation and blatantly fake news, whatever the car's spitting out, it's exiting through what looks like a version of the 2018 Mustang's new quad-tipped Active Exhaust.The real story today is the tires.Ford's so secretive about this thing engineers purged almost all discernable markings from the sidewalls of the tires, leaving only “305/30/ZR20” visible on the front tires, just like Chevrolet's new Camaro ZL1 with the 1LE track package tacked on. For comparison, the Shelby GT350 uses 295-section fronts and 305s in the back, while the R ups that to 305/315.The shooters think the prototype is actually wearing a set of Michelin's new Pilot Sport 4S rubbers. Based on Ford's behavior in the past, the wheel covers are probably hiding a set of carbon ceramic rotors, plus calipers that could stop a jet plane.There's no time frame for when the project will go public, but look for the sightings to increase as we head into the summer.
