Ford may not have plans to grace Americans with a Ranger Raptor from the factory, but that hasn't stopped Texas-based Hennessey Performance Engineering from doing it anyway. After announcing plans for the Hennessey VelociRaptor Ranger last month, HPE dished out the final specifications for its...

The mad individuals at Hennessey Performance Engineering have created their first 2019 Corvette ZR1 with 1,000 horsepower.

Hennessey Performance Engineering will gladly replace the Ford F-150 Raptor's twin-turbo V-6 with a V-8, and that appealed to professional wrestler and action star Dwayne "The Rock" Johnson. HPE posted photos to its official Facebook page on Tuesday showing The Rock's latest ride. It's a baby blue...

Ford has no plans to introduce the current Ranger Raptor in the United States, so Hennessey Performance Engineering will essentially do it for the automaker. On Monday, the Texas-based tuning company announced the Ford VelociRaptor Ranger. The VelociRaptor name should be familiar to anyone who...

The Dodge Challenger SRT Demon is already one hell of a car, but Hennessey Performance Engineering has (of course) gotten a hold of it and made it something more. With the company's HPE1000 package, the Demon makes a whopping 880 horsepower at the rear wheels. That equates to around 1,035 hp at the...

The second-generation Ford F-150 Raptor ditched its 6.2-liter V-8 for a twin-turbo V-6. While that's fine and dandy, it certainly doesn't provide the same soundtrack. Enter Hennessey Performance Engineering, which has installed a 5.0-liter supercharged Coyote V-8 engine to appease those who can't...

Veteran General Motors engineer John Heinricy has come out of retirement to lead development of Hennessey's Venom F5 hypercar. Hennessey made the announcement on Tuesday, confirming that Heinricy is chief engineer for the project. Heinricy, 71, finally left GM in 2008 after first joining the...

The VelociRaptor 6x6 debuted at the 2017 SEMA show and ushered in America's own answer to 6x6 rivals from Mercedes-AMG and Kahn Design. As for why this truck is...

A number of Ford F-150 Raptor fans have been crying out for a V-8. Hennessey Performance Engineering has heard those cries because the Texan tuner has built a Raptor housing eight cylinders under the hood. From the factory, there's only one engine choice available for Ford's latest Raptor. It's a...

Hennessey Performance Engineering is always working on the next best thing. And by next best thing, we mean the next fastest car or SUV. Case in point is the company's HPE1200 package for the Jeep Grand Cherokee Trackhawk. On Monday, we brought you a video of Hennessey's HPE1000-enhanced Grand...

The Ford GT is very quick. The Jeep Grand Cherokee Trackhawk is also very quick. There's no way that it's as quick as the GT though, right? Well, after a visit to Hennessey Performance it's actually quicker. At least that's the case over the quarter-mile drag strip. Hennessey CEO and founder John...

Hennessey Performance Engineering is back with another madly modified creation. This time it's a Ford F-150 that's been dialed up to produce 758 horsepower.

Hennessey Performance Engineering in Texas is focused on building speed machines, and its latest goal is hitting the 300-mph mark with the F5 Venom, then flying past it.

The race to 300 mph is officially on. Hennessey Performance Engineering plans to begin testing an F5 Venom prototype in 2019, with high-speed validation testing by the end of that year. "We believe our car is capable of going well beyond 300 mph," CEO John Hennessey said. What will enable the F5...

For Hennessey Performance Engineering faithful that couldn't swallow the idea of owning a Ford-based Velociraptor, the Goliath 6x6 has arrived. It's based on the 2019 Chevrolet Silverado 1500, and like the F-150 based pickup, it's powerful, off-road ready, and utterly bonkers. Hennessey revealed...

Just a few short years ago, there would have been no way we'd believe that a mainstream automaker would sell a street-legal, 840-horsepower coupe. But Dodge does just that and the car is appropriately called the Demon. As is often the case though, tuning shops love taking already insane things and...

Hennessey Performance Engineering in August unveiled the 2019 Heritage Edition Ford Mustang to celebrate hitting the 10,000-build milestone. The fiery red car, which features a design inspired by the livery of a 2018 Ford GT Heritage Edition supercar owned by Hennessey boss John Hennessey, is based...
