Hennessey shows the potential of its HPE850 Hellcat
It is clear that the stock Hellcat is a very cool muscle car. But it is also as plainly as anything that the modified Hennessey HPE850 Hellcat is better than any production version. But have you ever asked yourself, what exactly would happen between those two in a Street Fight. You don’t have to wonder anymore, because Hennessey Performance ha shot this amazing “Street Fight video”.
The Hellcat is probably one of the Seven Wonders in the automotive world. It looks great, has that muscle car stance and performance and it features attitude. Maybe, it is not everybody’s cup of tea, but hey, we live in a free world. And it is exactly what I like.

For those wanting more from their muscle car cat-beast, Hennessey Performance has produced the so called HPE850 Upgrade. As the name shows, it boosts the power of the 707hp Challenger to the potent 850 hp and this happens at 6,200 rpm.

Here’s the boring information: the upgrade comprises of new ECU and upgraded tuning software. By the way, you can see the chassis dyno testing in the second video featured in this post. Going back to the point, the HPE850 also adds high flow air filter element, lower pulley upgrade that increases boost by 1-2 psi, port matched throttle body, Hennessey embroidered head rests for the interior as well as Hennessey and HPE850 exterior emblems. As usual, the performance company has featured serial numbers on the dash plaque and plaque in the engine compartment.
At last, we all know that the Hennessey Hellcat HPE850 was going to win. Maybe the point in this video was to show how much faster Hennessey’s variant is.

Prior-Design is mostly famous for its exclusive tuning and aerodynamic kits as well as beautiful sets of wheels. We can hardly expect from these experts engine uprating or even something that can bring out more from the inherent power of car’s powerplant. However, the case with their latest project is actually the opposite and we have surprisingly found that Prior-Design can actually make things pretty cool!
If the devil had a ride it would be most definitely this Dodge Challenger Hellcat. With its Red Hot exterior paint scheme and one-off tuning pack, this is the most badass vehicle we have seen for awhile. Four different names are involved in the making, precisely Liberty Walk, KW, PUR Wheels and the Canadian tuning masters at SR Auto Group.
Liberty Walk Dodge Challenger Hellcat might seem to you as a very common name if you follow our blog regularly. And it is common. We have seen a similar car a couple of months ago, which was the result of the joint work of Liberty Walk and SR Auto Group. Unlike the first white car, this example comes in toxic green exterior color and this and no other reason (like electric motor) makes the vehicle go green.
Liberty Walk Dodge Challenger Hellcat. This is the answer to the question “What is common between United States, Canada and Japan?” You might also ask, what does Canada have to do with it. Well, this is actually the first Liberty Walk Hellcat unleashed in Vancouver by our fellows at SR Auto Group. In addition, they also added some extra detailing, that makes the muscle car look even more astonishing!
