Hennessey took the Jeep Grand Cherokee Trackhawk and made an already fast SUV even faster. The company completely rebuilds the engine with new pistons, rods, and ported cylinder heads along with a giant supercharger and lots of other mods to squeeze 1200hp out of the car. That works out to about 1003hp and 892 lb-ft of torque at the wheels.
That is enough power to push the big 4-door SUV to 60mph in 2.3 seconds, and run the quarter mile in 9.6 seconds at 145mph; the top speed is over 200 mph. Hennessey says this is the quickest accelerating SUV in the world.
Engineering Marvel
The transformation of the Jeep Grand Cherokee Trackhawk into the Hennessey HPE1200 is nothing short of an engineering marvel. The extensive modifications include not just the engine rebuild but also enhancements to the drivetrain, suspension, and braking systems to handle the immense power. The new pistons and rods are forged for maximum durability, while the ported cylinder heads ensure optimal airflow. The giant supercharger, a key component, significantly boosts the engine’s performance, making it capable of producing 1200hp.
Additionally, the vehicle’s cooling system has been upgraded to manage the increased heat generated by the high-performance engine. This includes a larger intercooler and improved radiator, ensuring that the SUV can maintain its performance even under extreme conditions.
Performance and Practicality
Despite its incredible performance, the Hennessey HPE1200 Trackhawk retains the practicality of the original Jeep Grand Cherokee. It still offers ample seating for five passengers and a spacious cargo area, making it a versatile vehicle for both everyday use and high-speed adventures. The interior remains luxurious, with premium materials and advanced technology features that provide comfort and convenience.
The Hennessey HPE1200 Trackhawk is not just about straight-line speed; it also boasts impressive handling capabilities. The upgraded suspension system includes adjustable dampers and stiffer springs, providing better control and stability at high speeds. The braking system has been enhanced with larger, high-performance brakes to ensure that the SUV can come to a stop quickly and safely.
Exclusivity and Warranty
The work is covered by a single year warranty or 12,000 miles, whichever comes first. The Hennessey HPE1200 Trackhawk sells for $179,000 and that price includes the base Trackhawk. Only 24 will be made and they are available to purchase globally.
The exclusivity of the Hennessey HPE1200 Trackhawk adds to its appeal. With only 24 units being produced, owning one of these SUVs is a rare privilege. Each vehicle is meticulously crafted to ensure the highest quality and performance standards. The limited production run also means that the HPE1200 Trackhawk is likely to become a collector’s item in the future.
The Hennessey HPE1200 Trackhawk is a remarkable achievement in automotive engineering. It combines the practicality and luxury of the Jeep Grand Cherokee with the extreme performance enhancements that Hennessey is known for. Whether you’re looking for a high-speed thrill ride or a versatile SUV for everyday use, the HPE1200 Trackhawk delivers on all fronts.
