Hennessey unleashes 2015 HPE700 supercharged Ford Mustang

Sun, 05 Oct 2014

Thanks to the 2015 Dodge Challenger SRT Hellcat there is a new magic number in the muscle car world – 707. To raise eyebrows these days in the power war, a vehicle needs to match or preferably exceed that palindromic figure. The tuners over at Hennessey took a look at it for their 2015 HPE700 Mustang and decided to go one better. Well, ten actually, because they bestowed their latest creation with 717 horsepower and 632 pound-feet of torque.

The HPE 700 Mustang takes the standard Mustang GT with its 5.0-liter V8 and turns up the power a few hundred notches with a Roots-type supercharger running at 7.25 psi. Hennessey claims that this boosted 'Stang can rocket to 60 miles per hour in about 3.6 seconds and cover the quarter-mile in 11.2 seconds at 131 mph. For those keeping score at home, those figures are very similar to Challenger Hellcat.

To cope with all of the added boost, the engine gets a high-flow throttle body, upgraded injectors, new fuel pump, stainless steel exhaust and Hennessey's calibration for the engine management. Pricing for the package is $59,500, including the base 2015 Mustang GT, but the company is limiting production to 500 units for the 2015 model year. Founder John Hennessey told Autoblog that he has already received about a dozen orders for them.

However, Hennessey is also offering a host of upgrades to make the Mustang even more aggressive, like carbon fiber pieces for the front splitter, side sills, rear diffuser and spoiler. Further enhancements include 20-inch wheels with Michelin Pilot Super Sport 2 tires and 15.1-inch Brembo front rotors.

Hennessey also talked about the company's future upgrades for the Mustang's 2.3-liter EcoBoost. He said in the neighborhood of 375 horsepower is possible with some tweaks, and based on the company's other experiences with EcoBoost engines, they are "easily tunable."

Texas-tuned HPE700 Mustang has firepower to battle Corvette Z06 & SRT Hellcat

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.
