Hennessey HPE800 Twin Turbo Jeep
Hennessey Performance isn't exactly known for its cautious, modest treatment of engines, so we probably shouldn't be surprised when it continues to pair outlandish output numbers with unlikely vehicles.
Still, when the shop nearly doubles the output of the most potent Jeep, allowing the off-road icon to beat the Ferrari 599 GTB to 60 mph, it manages to ruffle our sensibilities just a bit.
Just in time for the holidays, Hennessey unveils the 2013 HPE800 Twin Turbo Jeep, which it introduces as so: "Who needs a reindeer when you have an 800-horsepower sleigh."
While Santa may still need a reindeer to leap the water bodies of the world, the average Jeep driver should be more than content with 800 horses.
Hennessey takes the 2012 Grand Cherokee SRT8, increases the size of its 6.4-liter HEMI V-8 to 7.0 liters and adds a twin-turbo system. Those modifications boost output from 470 to 805 horsepower and up torque to 823 pound-feet at 4,000 rpm.
In addition to the staggering engine upgrade, Hennessey upgrades the transmission and torque converter, adds a lowered sport suspension, and adds 15.1-inch Brembo brakes in front and back. The HPE800 Twin Turbo also gets 20-inch alloy wheels, a carbon fiber front splitter and a custom leather interior with Alcantara steering wheel.
When all is said and done, the HPE800 Twin Turbo Jeep is capable of hitting 60 mph from rest in 3.1 seconds, putting its performance more in line with a six-figure supercar than any average off-roader. That's good, because its $235,000 base price also has more in common with a supercar.
In case you're wondering if anyone would ever want to spend that kind of money for a juiced jeep, John Hennessey is plenty confident that he'll sell all 24 planned examples.
Hennessey said in a statement: "We've built dozens of 600-800 horsepower Jeep SRT8s over the past five years, so we have an existing client base who will want to upgrade the new Jeep Grand Cherokee SRT8 to an even higher level. This vehicle is designed for the performance minded driver who lives in Aspen or Moscow and wants to be the fastest in all weather conditions."
