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->ke428 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->ke31 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.

Ford will likely slot the Mach 1 between the standard GT and any upcoming Shelby editions. With the Boss 302 biting the dust for 2014, we imagine that moniker will likely stay in retirement for a few years, giving room for the "Mach 1" nameplate. Itself coming from a hiatus, the Mach 1 name brushes off 11 years of dust, as it was last used in 2004.

Performance wise, the Mach 1 will likely see suspension upgrades to match its suspected increase in power. We can only imagine the increased road-holding abilities the base and GT Mustangs will have over the outgoing solid-axle car, with its new independent-suspension setup out back. Such a setup will allow for even more tweaking and refining that will include more track-oriented shocks, springs, and bushings.

The Mach 1's competition will likely be very familiar with this view. Mustangs have always (save for the dogish Mustang II) been straight-line track stars and the 2015 Mach 1 will be no different. Zero to 60 mph times should be in the very low 4- or high 3-second range. (A 2013 Mustang GT did 0 to 60 mph in 4.3 seconds in the hands of MotorTrend.)

Keep in mind, these numbers are all an estimated guess at best. Our graphic artist, however, is usually very close to what's seen rolling off the assembly line. In the mean time, we're keeping our fingers crossed that Ford moves forward with the Mach 1.
