Hennessey Performance (HPE) is well known for taking fast cars, trucks and SUV's and making them faster. The company will be offering their HPE800 Twin Turbo Jeep for 2013. Based on the new Jeep Grand Cherokee SRT8, the crew from HPE takes the factory 6.4 L Hemi and increases displacement to 7.0 L (426 cubic inches) while adding a twin turbo forced induction system. The resulting 805 bhp and 823 lb-ft of torque will be enough to propel the HPE800 from 0-60 mph in 3.1 seconds.
