Hennessey Performance announced details of their first tuning package for the new Ford Mustang, and it’s a biggie. They are proposing a HPE700 package for the Mustang GT V8 with 717 horsepower 632 lb-ft torque.
In comparison, the standard 2015 Ford Mustang GT comes with 435 horsepower and 400 lb-ft. So whichever way you cut it, that it a huge gain. To achieve that immense power Hennessey had to take out most of the 5.0 engine and replace it with high-performance parts.
The meat of the package is a Roots-type high-helix supercharger packing 7.25 psi of boost mated to a a high-flow throttle body and stainless-steel exhaust system. Complementing these bits are an upgraded cooling system, uprated injectors, fuel pomp and engine management software.
Lately Hennessey has developed an affinity for body kits, so as part of the HPE700 package you can order a carbon fiber aero kit for your Ford Mustang, consisting of front splitter, side sills, rear diffuser and rear lip spoiler. Hennesse recommends a set of their own 20-inch H10 wheels shod with Michelin Pilot Super Sport 2 tires to go with the kit, as they work best with the 15 inch Brembo brake discs they have fitted to the car.
Performance-wise, Hennessey Mustang 2015 does 0 to 60 in 3.6 seconds and runs the quarter mile in 11.2 seconds@ 131 mph. It’s shame they will only make 500 HPE700s, especially as it is fairly reasonably priced at $59,500 USD including the base car.
