It also completed the quarter-mile sprint in 10.7 seconds at 132 mph.
Most would agree that the 707-hp 2018 Jeep Grand Cherokee Trackhawk is already absurdly powerful – unless you're John Hennessey. The Texas tuning company recently unveiled its HPE850 Upgrade package for the high-performance SUV that cranked the power up to 852 horsepower. But just in case that still isn't enough for you, Hennessey now also offers an HPE1000 Supercharged Upgrade that modifies the Trackhawk's powertrain to pump out an astonishing 1,012 hp at 6500 rpm and 969 lb-ft of torque at 4200 rpm.
To achieve this monumental upgrade, Hennessey has fitted a 4.5-liter supercharger that produces 14 psi of boost. The extensive modifications include stainless steel long tube headers, a high-flow supercharger bypass valve, upgraded high-flow fuel injectors, tweaks to the ECU software, and a high-flow air induction system.
As you would expect, these upgrades have resulted in monumental performance gains. To see what it can do, Hennessey took the 1000-hp Trackhawk for a performance run at the drag strip where it accelerated to 62 mph in 2.7 seconds and completed the quarter mile sprint in 10.7 seconds at 132 mph. Such rapid acceleration puts it in the same league as modern supercars like the Ferrari 488 GTB, Lamborghini Huracan, and Audi R8 V10 Plus, despite being substantially heavier. Orders for Hennessey's HPE1000 Supercharged Upgrade are now open, but prices haven't been revealed.
This isn't the only 1000-hp beast Hennessey has created, either. Just recently, the tuner's HPE1000 Dodge Demon achieved a 9.14-second quarter-mile time at 152 mph and a 1.9-second 0-60 mph time.
