Hennessey HPE700 2015 Mustang dyno: 663rwhp, 524rwtq

The 2015 Mustang GT was a crowd favorite during our Performance Car of the Year testing, its 435 hp and razor-sharp chassis letting it hang with cars with fine European pedigrees and ascot-quivering price tags. But enough is never truly enough, and the gasoline addicts at Hennessey Performance just dyno-proved a monster Mustang: How does 663 horses and 524 lb-ft at the rear wheels suit you?

Hennessey's HPE700 package slaps a meaty 2.9-liter supercharger and all the requisite fuel and computer add-ons atop the new Mustang's 5.0-liter mill. It all adds up to a claimed 717 hp and 632 lb-ft at the crank, says Hennessey–good for a tuner-claimed 0-60 of 3.6 seconds, on the way to an 11.2-second quarter-mile at 131 MPH. I should point out, that's on 93 octane gas–but it utilizes the Mustang's factory-stock exhaust system.

Those numbers will make Corvette Z06 and Challenger Hellcat owners sweat a little bit, as will the price: Hennessey says the whole kit will roar out the door for as little as $59,500, including the cost of the 2015 Mustang GT on which it's based.

How's it sound? Surprisingly quiet, thanks to the stock exhaust. But still absolutely vicious.

That is an underrated 707HP. That car would be a beast on the street. Very strong.

Mph in quarter seems a little low. And through stock exhaust! Wow.

Very impressive, but who gives a rip how it compares to a Z06 or Hellcat? Those are FACTORY vehicles that have to meet emissions, very long term warranty's and all sorts of Federal regs.

Tuners do not have nearly as much red tape to cut through.

All are impressive in their own rights.
