What do you get when you combine the legendary Ford Mustang with the mechanical genius of Hennessey Performance Engineering?

717 horsepower.

632 ft.-lbs. of torque

0-60 times under 3.6 seconds.

And so on and so forth.

Those are the numbers promised with the limited-edition Hennessey HPE700, a 2015 Ford Mustang GT with Hennessey upgrades. It features the 5.0L Coyote engine, but with a Roots-style supercharger that delivers 7.25 psi of boost. It also has an upgraded throttle body, injectors, and fuel pump, along with a special engine tune. You can see a more complete account of the modifications in the Road & Track story.

Hennessey will create only 500 of the HPE700s for 2015, and the price will be $59,500–just under Hellcat money. And for those of you interested in our Mustang EcoBoost story, there’s also supposedly a package for the 2.3L in the works as well.
