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...

It's fairly common knowledge that the horsepower figures automakers parade around don't reflect power at the wheels. Rather, it's how much hp the engine makes at the crankshaft. Therefore, we need a dynamometer to measure just how much power is getting to the ground. Thankfully, Hennessey...

Cadillac's brute in a suit, the CTS-V, has been a regular at Hennessey's gym and now it's bristling with with 1,000 horsepower and 966 pound-feet of torque. The standard CTS-V is certainly no slouch with its 640 hp, but Hennessey's HPE1000 version is simply an insane-o beast of a sedan. Just listen...

Using the YouTube status bar as a timing system isn't exactly a concise tool. But it's all we have to go on in this video of John Hennessey driving his 2018 Ford GT from a dead stop to 180 mph. Also, we assume that's Hennessey only because we're not sure we'd let someone else do that in our own...

John Hennessey, founder of Hennessey Performance Engineering, says being the fastest really matters. It's a goal he aims to achieve with the Hennessey Venom F5 supercar. Speaking to Autocar in a report published on Monday, Hennessey said the "fast is best" ethos comes from the company's customer...

Texan tuner Hennessey has been cooking up serious power for the already seriously powerful 2018 Jeep Grand Cherokee Trackhawk. Out of the box, the super Jeep pounds the pavement with 707 horsepower. Hennessey's HPE1000 version? This one reportedly cranks out over 1,000 horsepower at the crank...

Hennessey Performance Engineering once looked to exorcise the Demon with the Exorcist based on the Camaro ZL1, but now the Texan tuner is fully embracing the dark side. The 2018 Dodge Challenger SRT Demon has been receiving attention from Hennessey's wrenches, and the company is ready to offer its...

Of course, Hennessey Performance Engineering tuned a Cadillac Escalade. But, not only has HPE tuned and modified the giant luxury SUV, the company has turned it into a drag strip slayer. To exemplify HPE's work, the company lined up its 805-horsepower Escalade next to a 2018 Chevrolet Camaro ZL1...

The purchase and ultimate delivery process that comes along with a supercar is a bit different than what you might experience when you buy the family sedan or truckster. Those vehicles are fine, but they don't deserve pomp and circumstance. A machine like the 2018 Ford GT, however, does. John...

Lincoln's Navigator impresses with its luxury and presence, but with a curb weight approaching 6,000 pounds the big SUV could definitely do with some added performance. Sure, the stock 3.5-liter twin-turbocharged V-6 is perfectly adequate with its 450 horsepower and 510 pound-feet of torque, but...

Hennessey Performance Engineering of Sealy, Texas recently pitted its HPE800 Cadillac Escalade against a stock Jeep Grand Cherokee Trackhawk. Before you cry foul about this being an unfair match-up, note that the Jeep is a mid-size SUV whereas the Cadillac is a full-sizer. The Jeep is also powered...

You can bet Hennessey Performance Engineering had one figure in mind when developing the Exorcist Chevrolet Camaro ZL1: the Dodge Challenger Demon's 9.65-second quarter-mile time. And it's not a surprise HPE was able to top the 9.65-second time with a 9.57-second quarter-mile run. Hennessey...

It was only a matter of time before Hennessey Performance Engineering got its hands on a 2018 Dodge Challenger Demon, and as usual, the Texas performance tuner performed baseline tests to see just how fast and quick the muscle car is. HPE performed three tests: a quarter-mile drag pass, a top speed...

Chevrolet has a monster on its hands in the Camaro ZL1. John Hennessey and his team know how to take a monster and turn it up to 11, and they've done just that with their Exorcist Camaro ZL1.The name came about as a means to combat Dodge's Challenger SRT Demon, and the Exorcist delivers with its...

Hennessey Performance Engineering is back again shortly after showing us the world's fastest Christmas tree with a Dodge Challenger Hellcat. This time, there aren't any holiday decorations onboard for a top-speed run. It's just pavement and a bone-stock Jeep Grand Cherokee Trackhawk. The premise is...

Hennessey Performance Engineering has put together two of the meanest muscle cars around in a good ol’ fashioned drag race. In one corner is the 2018 Dodge Challenger SRT Hellcat Widebody. And in the other is the 2018 Jeep Grand Cherokee Trackhawk. Both are among the most powerful cars in...

It's the answer to a question only Hennessey Performance Engineering would ask: How fast will a Christmas tree go when strapped to the roof of a Dodge Challenger Hellcat wide-body? You know, for those times when a last-minute Christmas tree is imperative. HPE ran a bone-stock Challenger Hellcat...
