Hennessey Celebrates 25 Years With an 800-HP Ford Mustang
Back in 1991, Texas car tuner John Hennessey began turning up the horsepower on Mitsubishi 3000GT VR-4 sports cars (née Dodge Stealth), catapulting them into stratospheric levels of performance and speed. Fast forward 25 years, and Hennessey doesn’t appear to have lost that need for speed. In fact, Hennessey Performance just injected the latest and greatest Ford Mustang with quite the performance dose, in celebration of their 25 years in business. This is it, and it’s called the Hennessey 25th Anniversary Edition Ford Mustang GT. It tacks on an aggressive cosmetics package, sticks a bunch of go-fast components underneath, and oh yeah, it also wields a titanic 804 horsepower. Better strap in.

Designated as “HPE800”, the special Mustang is in effect an evolution of Hennessey’s HPE700 package for the 5.0-liter V8 GT, with the power turned significantly north—a bump of 87 horsepower and 16 pound feet of torque (up to 648 lb.-ft.). Power comes courtesy of a 2.9-liter Whipple supercharger, now met with uprated fuel injectors, an upgraded fuel pump, and a new carbon fiber air intake and axle-back exhaust.
As one might expect, on-track performance is quick. The Hennessey Mustang blitzes to 60 mph in a hair over three seconds, rips through the quarter mile in 10.7 seconds, and if fully unleashed, it’ll smash the 200 mph barrier up to a top speed of 207.9 mph.

What makes this Mustang especially mean however is its aggressive body kit. Hennessey adds a heady carbon fiber front splitter, side skirts, and rear spoiler, plus racy 20-inch wheels, Brembo front brakes, and a lowered KW suspension kit. Special graphics also highlight the pony car’s flanks, reminiscent of the iconic Boss 302 Ford Mustangs.
Pricing for the super-mean Hennessey Mustang has yet to be announced, however given its performance pedigree and limited availability—just 25 Mustangs will get the special treatment—it likely won’t be cheap.
