Hennessey Performance Jeep Grand Cherokee SRT8


Updated on

Hennessey Performance sent us a surprise for the holidays with this 2013 Jeep Grand Cherokee SRT8 package. Under the hood is a Hennessey HPE800 Twin Turbo engine kit that was hooked up to the bored out factory 6.4-liter HEMI V8. Displacement is now at 7.0-liters, allowing the large twin turbochargers to put down 805 horsepower and 823 lb-ft of torque. A huge increase from the stock 465 hp and 465 lb-ft of torque. At the track, the modified Jeep Grand Cherokee now sprints from 0 to 60 mph in just 3.1 seconds, which is damn good for a full-size SUV.

Extra performance parts installed on the Jeep tuning project include an upgraded transmission with torque converter, a new Brembo 15.1-inch brake kit, sport suspension system, and light alloy wheels. New aero parts consist of a carbon fiber front splitter to give a more aggressive look. Inside the custom Grand Cherokee is new leather with an Alcantara steering wheel.

Besides the nice power increase, what’s really mind blowing is the price tag for this tuning job. A factory 2013 Jeep Grand Cherokee SRT8 is priced at $55,295 USD, yet Hennessey plans to charge a whopping $235,000 USD with the car included for these customizations!
