Just in time for the festive season, Hennessey has released a rendering of their take on the SRT8 with the tag line: "Who needs reindeer when you have an 800hp twin turbo sleigh?" Quite. The factory 6.4-liter HEMI V8 has had its displacement increased to 7.0-liters and a hefty twin turbo system fitted. 465hp and 465lb-ft of torque gets cranked up to 805hp and 823lb-ft of torque in the Hennessey SRT8 and the result is a Porsche Turbo-beating 0-60mph time of 3.1 seconds, down from 4.8.

Hennessey says its HPE800 Twin Turbo can also do the quarter-mile in 10.9 seconds at 130mph. Santa's gonna love that. In addition to performance upgrades, the Jeep gets an upgraded transmission system and torque converter upgrade, 15.1 inch Brembo brakes, a lowered sport suspension, lighter alloys, carbon-fiber front splitter and a custom leather interior with Alcantara steering wheel. Limited to 24 vehicles and priced at $235,000 this is HPE's most lethal Jeep SRT8 and one that can handle all weather conditions at serious speed.
