Hennessey has kept tweaking the Mustang to create the 774-horsepower HPE750. The supercharged pony car recently hit a GPS-verified 207.9 miles per hour at the Continental Tire Proving Grounds in Texas, and it was all captured on video.


John Hennessey took his personal 2015 HPE700 Supercharged Ford Mustang to the Continental Tire Proving Grounds in Texas to see just how fast the muscle car would go. It managed 195.4 miles per hour when it hit the limiter going down the straight.


We knew that once Hennessey Performance got its hands on the seventh-generation Chevrolet Corvette Stingray, big things were going to happen. A 200.6-mile-per-hour run on a closed section of Texas' brand-new State Highway 99, was just a shade bigger than what we were expecting. The run was also a test of the new toll road - which Hennessey founder John Hennessey called "perfectly smooth" - and the RFID toll system, which was still able to tag the Corvette at 200 miles per hour (toll dodgers bewa


Raptor, Excursion, Texas And Hennessey


Hennessey Performance Engineering has created an HPE650 package for the Jeep Grand Cherokee SRT fitted with the 6.4-liter Hemi engine. When it leaves the showroom floor it has 470 horsepower and gets from 0-60 miles per hour in 4.8 seconds. When it leaves Hennessey's garage floor after the upgrade it has 650 horsepower – 530 hp at the wheels, according to Hennessey – and gets to 60 mph in 3.9 seconds on its way to running the quarter-mile in 12.6 seconds.


We're happy there's a John Hennessey who walks the Earth. While any number of humans may have had the idea of marrying a stretched Lotus with a twin-turbocharged ZR1 engine, only Hennessey had the wherewithal to make the Venom GT. And because he has, we bring you the news that the Venom GT has officially broken the world record for a car traveling from 0 to 300 kilometers per hour.


John Hennessey has stopped by Jay Leno's Garage for a second time to show off the 2012 Hennessey Venom GT. Last time the tuner-turned-supercar-maker visited the comedian's garage, Leno didn't get a shot behind the wheel of the Venom GT because the vehicle had yet to be legalized in the States. That was then. Now, the 1,200 horspeower beast has all of its paperwork in order, and Hennessey has been kind enough to hand over the keys to one very yellow Venom GT. Leno proceeds to take the machine out


The image above is a perfect example of potential energy. What we have is famed tuner John Hennessey's own personal daily driver, a modified Cadillac CTS-V Sport Wagon called "Hammer Wagon," about to run down the quarter mile. Its twin-turbo V8 is producing upwards of 1,000 horsepower, but with the Christmas tree still glowing red, it's got nowhere to send that energy.


John Hennessey recently returned to the Texas Mile with his 700-horsepower Cadillac CTS-V Sport Wagon for another shot at high-speed glory. The long-roof rocket managed to clip off a top speed of 189.7 miles per hour in the standing mile, which beat out last year's figure by a safe margin.


And now for something completely awesome: the 2010 Hennessey V650 Cadillac CTS-V Sport Wagon doing terrible things to expensive tires. John Hennessey's love affair with all things Cadillac is no secret; his wife's daily driver is an HPE700-equipped CTS-V sedan. We've also seen Mr. Hennessey's insatiable lust for showing off his cars embarrassing more expensive metal.
