Just when you thought Hennessey couldn’t be any more mental, here it is developing a program for the 2015 Ford Mustang GT that can legitimately give the Chevrolet Corvette Z06 and the Dodge Challenger Hellcat something to sweat about. The American tuner famous for his Venom GT has developed a program for the Mustang that’s tantamount to giving it performance-enhancing drugs. It’s a comprehensive kit that includes exterior, interior, and performance upgrades that could give the Mustang as much as 700 horsepower. The programs is called the HPE700 for a reason, right?

But here’s the bad news; Hennessey’s only building 500 units of the HPE700, making it important for interested customers to pick up their phones and at least express interest in buying one. Each program costs $59,500 and that includes a Mustang GT. That’s a pretty sweet deal relative to the rage and fury your Mustang GT will have under its hood.

Should we have really expected anything less from Hennessey? I think not...

We’re under no illusions that the real meat and bones of Hennessey’s HPE700 program for the 2015 Mustang lies under that hood. But like the aftermarket company said, customers can also opt for some personalized touches to the Mustang, including a front splitter, side sills, a rear diffuser, and a rear lip spoiler all made from carbon fiber.

A set of 20-inch Hennessey H10 wheels are available as an option. These wheels are wrapped in Michelin Pilot Super Sport 2 tires. Buyers can also opt for a set of Brembo brake package that includes 15.1-in. front rotors.

This is where it really gets interesting. See, Hennessey’s got an HPE700 Supercharged upgrade that injects 7.25 PSI of boost into the Mustang’s 5.0-liter, V-8 engine. Hennessey also installed a high-flow throttle body, a new stainless-steel exhaust system, upgraded injectors and fuel pump, and a new ECU calibration. These components all do their parts in bumping the engine’s output from 435 horsepower and 400 pound-feet of torque, to 717 horsepower at 6,600 rpm and 632 pound-feet of torque at 4,400 rpm. Those numbers now allows the Mustang to hit 60 mph in just 3.6 seconds to go with a quarter-mile time of 11.2 seconds at 131 mph.

Hennessey also includes a few other bits to help people recognize that this is no normal Mustang GT. These aesthetic add-on components include Hennessey , HPE700 and Supercharged exterior badging, Hennessey floor mats and serial-numbered plaques in the engine compartment and on the dash;.

Kirby’s first exposure into the world of automobiles happened when he caught Knight Rider on television as a five-year old boy. David Hasselhoff didn’t leave much of an impression on him (that happened later on in Baywatch), but KITT certainly did. To this day, Kirby remains convinced that he will one day own a car with the same ‘spirit’ as the original KITT (not the 2008 monstrosity). He doesn't know when that will be, but until then, he’s committed to expressing his love for KITT, and all cars for that matter, here at TopSpeed.  Read More

Hennessey to Offer 717 HP Supercharged 2015 Ford Mustang

Sealy, Texas-Hellcat and Z06, be very afraid. Because when that 2015 Mustang 5.0L with the Hennessey script on its decklid sidles up next to you at the stoplight, it might very well be packing 717 supercharged horsepower. Dig the spurs in, pilgrim, and she’ll bolt to 60 mph in a scant 3.6 seconds. Keep your foot down, and the pressurized Coyote 5.0-liter 4-cammer will blaze to a white-hot 11.2-second quarter mile at 131 mph. It’s ponycar meets supercar.

"We’re very excited about the 2015 Ford Mustang and so are our performance-minded clients," said John Hennessey. "Our HPE700 Supercharged upgrade will elevate this Motown Missile’s performance to rival some of the fastest European sports cars. We can’t wait to share our specially tuned Mustang with the world!"

"This thing is uncaged, absolutely nuts," says Hennessey partner Don Goldman. "We’re thrilled to offer a 2015 Mustang that will outperform some of the fastest cars currently offered, at a lower price point."

Key to that 717 bhp (and the HPE700’s deep well of torque-632 lb-ft at 4400 rpm) is the Roots-type high-helix supercharger packing 7.25 psi of boost. Helping the Coyote V8 breathe more deeply is a high-flow throttle body and stainless-steel exhaust system. Upgraded injectors and fuel pump help feed the V8, under command of Hennessey’s proprietary engine management calibration.

Just 500 units of the HPE700 will be produced for the 2015 Mustang model year. Pricing starts at $59,500 USD including the base 2015 5.0L Mustang GT. But greater personalization and performance can be had by adding options such as CarbonAero carbon-fiber bodywork (front splitter, side sills, rear diffuser and rear lip spoiler), 20-in. Hennessey H10 wheels shod with Michelin Pilot Super Sport 2 tires, and a Brembo brake package with 15.1-in. front rotors. As a package, they give the Mustang improved downforce, cornering and braking to keep pace with the colossal supercharged power.

New 2015 Hennessey Mustangs can be ordered through any of AutoNation’s 37 Ford dealerships across America. A high-performance upgrade for the 2.3-liter EcoBoost-powered Mustang is also under development.
