2014 was a great year for the Mustang. The sixth-generation model debuted with an independent rear suspension, a first for the nameplate, an EcoBoost four-pot, and the most powerful GT in history. All these feats, as well as its global availability, earned it the the 2014 TopSpeed New Car of the Year award. Last year also brought the Shelby GT350, a track-suited muscle car powered by the first-ever Ford production engine to use a flat-plane crank and, at more than 500 horsepower, the most powerful naturally aspirated mill the company has ever created. Thankfully, Ford didn’t stop there. The lighter and meaner GT350R broke cover at the 2015 Detroit Auto Show, giving us a strong contender for this year’s Performance Car of the Year award. What’s more, the 2015 Mustang is set to receive a host of aftermarket upgrades, one of which is the spectacular HPE700 package by Hennessey Performance.

The main highlight of this upgrade is a supercharger that injects 7.25 PSI of boost into the Mustang’s 5.0-liter, V-8 engine, increasing its output from 435 ponies and 400 pound-feet of torque to a whooping 717 horsepower and 632 pound-feet. Of course, this massive output update also benefits from a high-flow throttle body, a new stainless-steel exhaust system, upgraded injectors and fuel pump, and a new ECU calibration. The new gear rushes the Mustang HPE700 from 0 to 60 in just 3.6 seconds and through the quarter-mile in 11.2 seconds.

More powerful than the 2015 Dodge Challenger SRT Hellcat, the HPE700 is definitely one of the coolest upgrades customers can add to the 2015 Mustang this year. The bundle comes to prove yet again why Hennessey is one of the best in the business and we have a feeling the Houston-based shop won’t stop here. But until HPE comes up with a new package, make sure you take a peek at the video above to watch the Mustang HPE700 at full throttle on the dyno.
