Hennessey Performance (HPE) got its start with modifying vehicles over 25 years ago back in 1991 in John Hennessey’s garage. HPE has now grown to a facility that’s responsible for making over 500 performance vehicles annually, and even has its own test track. Hennessey offers a plethora of performance packages for an assortment of different makes and models, but they also sell turn-key vehicles that are ready to drive off their lot. According to their website, “Hennessey is one of the largest independent automotive tuners in the world and has built over 10,000 specialty vehicles.”
The founder and president of Hennessey Performance is John Hennessey, who got his start as performance as a racer; setting early records with his Mitsubishi 3000GT that he built. Now in his state of the art facility in Texas, each vehicle built by HPE receives both a serial numbered plaque in the bay and the dash, some even come signed by HPE tech that built the vehicle and Mr. John Hennessey himself. In addition to all the extra performance goodies, each HPE upgraded vehicle has custom Hennessey Performance badges to let you know it has something special under the hood. All HPE vehicles also receive some sort of warranty to ensure that your extra power was built properly. Hennessey Performance takes already fast vehicles and makes them faster, and has even set a few world records along the way.
Let’s take a look at 20 of the best Hennessey Performance built vehicles.

According to HPE, the ZL1's 6.2-liter would receive an upgraded supercharger along with a laundry list of upgrades to go with it.
HPE says it will make 1000 hp at 6500 rpm and 883 lb/ft of torque at 4500 rpm. The official numbers haven’t been recorded yet, but Hennessey project its zero-to-sixty to be less than three seconds, with its quarter mile time being under ten.

It will take less than 11 seconds to run a quarter mile, and the GT needs just 3.1 seconds to get from zero-to-sixty.
17 Velociraptor 25th Anniversary
If sports cars aren’t your thing but you still wanted a 25th anniversary vehicle, Hennessey is also offering just 25 of their 25th Anniversary Velociraptors to help celebrate their birthday.
Hennessey took the Ford Raptor, which according to Ford was already capable of already making 450 hp; and were able to tack on over 250 extra horsepower, making 704 hp total.
According to HPE addition to getting some more power, Hennessey will do extensive upgrades to the suspensions to make the ultimate off-road truck.
16 Cadillac Escalade
Up next Hennessey decided to see what they could do a massive SUV, and upgraded the Cadillac Escalade. Hennessey offers two levels of performance packages for the Cadillac Escalade. The top of the line upgrades supercharger will be adding 10 psi of boost to the equation to an upgraded 416 CID stroker motor, by doing so HPE increased the Escalades performance to 805 hp at 5500 rpm and 812 lb/ft of torque at 4000 rpm. The supercharged Escalade can get to sixty in just 3.7 seconds, and needs 11.7 to get a quarter mile done to ensure that the kids will make it to soccer practice on time.
15 Jeep Trackhawk
The all new Jeep Trackhawk was released earlier this year, and according to Jeep, straight out of the box the Trackhawk 's supercharger 6.2-liter makes an impressive 707 hp. The folks over at Hennessey thought those numbers weren't good enough and decided to see what they could do to the beast.
According to HPE, they were able to increase the Trackhawk’s numbers to 1012 hp at 6500 rpm and 969 lb/ft of torque at 4200 rpms.
When it came to track it needed just 10.7 seconds to get a quarter mile done, needing just 2.7 seconds to get to sixty.
14 Jaguar F-Type
Hennessey doesn't discriminate when it comes to what vehicles they upgrade, and they even made an upgrade package for Jaguars that is available for all 2014-2017 models that have a 5.0-liter V8. According to HPE the upgraded package for the F-type includes upgrades to the supercharger and cooling system in addition to professional tuning. Doing so HPE was able to get 616 hp at 597 lb/ft of torque at 4200 rpm, making the Jag capable of doing zero-to-sixty in 3.2 seconds and needing just 11.4 for a quarter mile sprint.
13 Lincoln Navigator
According to their website, “Hennessey is the first tuner to offer performance upgrades for 2018 Lincoln Navigator.” HPE explained that since the new Navigator comes packed with essentially the same engine as the Ford Raptor, it only made sense to make a performance package for it as well. HPE will be offering packages that make both 500 or 600 hp depending how crazy you want to get. The 600 hp model can do zero-to-sixty in 4.8 seconds, needing less than 13 seconds for the quarter mile.

Earlier this year Dodge release the Dodge Demon, a true race car with according to Car and Driver is capable of making 808 hp, with the Demon Crate package that will tack on on some extra power to bring the total up to 1035 hp.

The supercharger gets upgraded to a 2.5-liter in addition to many other power makers to make 880 hp at 6500 rpm with 806 lb/ft of torque.
There is an even better upgrade their calling the HPE 1200, but so far the specs are pretty air tight; Hennessey did say it will come fitted with a NHRA roll cage in addition to a parachute.
11 Lamborghini Huracan
Up until now we have seen what Hennessey can do to sports cars, SUVs, and trucks; but what happens when they get their hands on a supercar? According to Car and Driver the Huracan at best has 631 hp when you upgrade to their performance package which adds all-wheel drive. To be quite honest, this seems pretty unimpressive considering it’s a supercar that cost over 200k. Luckily HPE decided to see what happened when they added twin-turbos to the Lamborghini’s massive V10. The boosted Huracan is now able to churn out 1000 hp at 7400 rpm.
10 Venom GT
Back in 2007 Road & Track Magazine decided to host a shootout to see who could do zero-to-200 the fastest. According to Venom GT’s official website, John Hennessey’s concept was made a reality when he had a sketch of what a Venom engine would look like in the back of a Lotus Exige. The results were the Venom GT that was capable of doing zero-to-200 in 20.3 seconds, finishing over 4 seconds faster than the Bugatti Veyron, winning the Road & Track shootout. HPE eventually got those numbers down to 14.51 seconds, which was fast enough to set a Guinness World Record.
9 Venom F5
Hennessey teamed up with Shell and Pennzoil to design to their very own Hyper-car they call the Venom F5; in hopes of being the fastest car on earth.
The F5 comes stocked with a custom-built HPE twin-turbocharged 7.6-liter power plant.
According to HPE the custom-built motor is capable of handling up to 24 psi of boost to help create 1600 hp at 7200 rpm. According to HPE they are only making 24 of these Hyper-cars with 15 orders already confirmed.
8 GMC Yukon
The Yukon is offered with two different engine options with HPE offering different level of performance packages for both. For the Denali’s 6.2-liter HPE upgrade you can expect the same performance as the Cadillac Escalade with the HPE performance package. As for the 5.3-liter, which according to Car and Driver is only good 355 hp.

HPE will upgrade the engine to a massive 7.0-liter still equipped with a supercharger, that will now make 1200 hp and 1066 lb/ft of torque. The HPE1200 ZR1 can do zero-to-sixty in just 2.2 seconds and needs just 9.2 for the quarter mile.
4 Audi R8
The Audi R8 comes standard with a 5.2-liter V10, but according to Car and Driver at best with its V10 Plus, it will make 610 hp so Hennessey decided to see what happened when you added some forced induction. The HPE Audi R8 adds twin-turbos and all the extra components needed to run boost to the equation upping the numbers to 900 hp at 7700 rpm and 685 lb/ft of torque at 4300 rpm.

The world was wowed by Dodge when they unveiled the supercharged 6.2-liter monster we now know as the Dodge Hellcat Charger, also made as a Challenger. It didn't take long for the folks over at HPE to figure out how ti make a performance package to increase its already great performance.

The Hellcat now needed less than 10 seconds to get a quarter mile done at 9.9 seconds, doing zero-to-sixty in 2.8.
1 Dodge Challenger Hellcat Redeye
It seems the folks at Dodge took notes from Hennessey Performance and decided to make a performance version of their already fast Hellcat Challenger themselves, calling it the “Redeye.” According to Car and Driver, the Redeye Hellcat Challenger could make 797 hp and 707 lb/ft of torque.
