If You Thought The Dodge Durango Hellcat Was Fast, The Hennessey’s HPE1000 Upgrade Will Blow Your Mind

After coming up with the 6x6 version of the world’s fastest and quickest production pickup truck, the Ram 1500 TRX, there was a lot of curiosity surrounding Hennessey’s next project. As it turns out, the company chose the world’s most powerful production SUV this time to give it a typical Hennessey twist. The aftermarket company has announced that it will be coming up with a 1,000-plus-horsepower iteration of the 2021 Dodge Durango SRT Hellcat.

As Though 700 Horses Weren’t Enough Already

Hennessey will be equipping the Durango SRT Hellcat with the HPE1000 supercharger upgrade package. It’s the same package that’s also offered on other Hellcat products, like the Dodge Charger, Challenger, and the Jeep Grand Cherokee Trackhawk. In the stock form, the Durango is powered by a 6.2-liter, V-8 HEMI supercharged mill under the hood.

This engine churns out 710 ponies at 6,100 rpm and 645 pound-feet of twist. Power is sent to all the wheels via a TorqueFlite eight-speed automatic transmission. The supercharger equipped is a 2.38-liter unit paired with twin-screw rotors. It takes 3.5 seconds to sprint to 60 mph from a standstill and has a top speed of 180 mph. The quarter-mile distance is covered in 11.5 seconds.

The HPE1000 upgrade package further ups the credentials. Working on the same engine, the SUV will make 1,012 horses at 6,500 rpm and 969 pound-feet of torque.

The engine will be paired to the same eight-speed transmission. As for the performance figures, the Hennessey Durango SRT Hellcat will take just 2.8 seconds to sprint to 60 mph, which seven-tenths of a second quicker than the fastest production SUV. The quarter-mile time is also trimmed down, now taking 10.8 seconds. For a three-row SUV, these figures are staggering.

The upgrades include:

  • Upgraded 2.65-liter Supercharger System
  • Pulley Upgrade
  • Stainless-Steel Long Tube Headers
  • Throttle Body Upgrade
  • High-Flow Catalytic Converters
  • Upgraded High-Flow Fuel Injectors
  • HPE Calibration Upgrade
  • Boost-a-pump Upgrade
  • High-Flow Air Induction System
  • Crank Case Ventilation System
  • All Necessary Gaskets & Fluids
  • Hennessey Exterior Badges
  • HPE1000 Badges
  • Serial-Numbered Plaques

For those of you wondering how it compares to the Jeep Grand Cherokee Trackhawk by Hennessey since it features the same package, the power outputs are identical – 1,012 horses and 969 pound-feet of torque. The performance numbers, however, are better than the Durango Hellcat’s. The Trackhawk achieves a 0-60 mph time of 2.6 seconds and a quarter-mile time of 10.2 seconds.

The Durango SRT Hellcat by Hennessey will come with a one-year/12,000-mile warranty. The company will run the SUV for around 200 miles to make sure all the niggles and bugs are sorted out before delivery. It will also be tested on a dyno. Hennessey hasn’t announced the pricing for it, but the same package on the Jeep Grand Cherokee SRT Trackhawk is offered for $34,950. The company, however, noted that only 50 examples of this build will be up for sale.

If you had to pick one of these SUVs with the HPE1000 package, which one would it be? The Jeep Grand Cherokee SRT Trackhawk or the Durango SRT Hellcat? Share your thoughts with us in the comments section below.
