News surrounding the 2015 Ford Mustang is still hot, as details about the coupe and convertible models keep rolling in. But now with a finalized exterior design, our rendering artist went to work piecing together what Ford’s rumored 2015 Mustang Mach 1 might look like.

High-performance with retro throwback flair is the name of the game and the exterior styling screams it. Up front, a huge front splitter with adjustable supports instantly stands out, while a larger rear spoiler and quad exhaust pipes juice up the rear end. The iconic Mach 1 logo adorns the rear truck lid in all its ’60-era font glory. Other small details, like the rocker panel and hood stripes, add character, while the vertical-bar Mustang logo replaces the galloping stallion on the front grille.

We can only guess at what lurks under those functional heat extractors on the Mustang’s hood, and guess we will. The current 2014 Mustang GT’s 5.0-liter V-8 cranks out 420 horsepower and 390 pound-feet of torque, and while Ford says the 5.0’s output is expected to be "at least" the same for the upcoming year, we suspect the 2015 GT to receive a marginal increase; perhaps to 430 horsepower and an even 400 pound-feet of twist.

Starting with those suspected output numbers, an estimate of 440 horsepower and 405 pound-feet of torque from the new Mach 1 sounds reasonable; especially considering the 5.0 produced 444 horsepower and 380 pound-feet in the 2013 Mustang Boss 302, which we expect the Mach 1 to basically be the replacement for.
