It’s been an exciting few months for the American auto industry. First, we had the undeniably badass 505-hp Camaro Z/28, and then came the 707-hp Challenger Hellcat followed by the 650-hp Corvette Z06. Texas tuner Hennessey wanted in on the action, and came up with the sinister HPE700 Mustang, based on Ford’s new-for-2015 pony car.
With its added supercharger, it makes 717 pavement-stomping horsepower. The Roots-type blower delivers 7.25 psi of boost, leading to 632 lb-ft of torque to go along with the horsepower. Hennessey also installs a high-flow throttle body and stainless steel exhaust system. Upgraded injectors and fuel pump feed more gas into the 5.0-liter V8.
Hennessey claims the Mustang will sprint to 60 mph 3.6 seconds, and cross the quarter mile in 11.2 seconds. That’s the same as the SRT Hellcat on its stock tires. Hennessey says only 500 examples of the HPE700 Mustang will be built for the 2015 model year. It’ll cost $59,500, which puts it right in the neighborhood of the Hellcat, ZL1 and last-gen’s GT500.
So what car would you prefer: the Hellcat, ZL1, Hennessey’s Mustang, or a GT500? Answer in the comments below.
