With a 6.4-liter HEMI V8 engine pushing 465-horses 465 lb-ft (630 Nm) of torque for 0 to 60 mph (96 km/h) sprint time of 4.8 seconds and a quarter mile time in the mid-13 second range, the regular 2012 Jeep Grand Cherokee SRT8 is one of the fastest production SUVs around.
But for Hennessey Performance Engineering [HPE], that’s not enough. The Texas based tuner, known for its outrageously powerful tunes, has done it again with the introduction of the 2013 HPE800 Twin Turbo Jeep Grand Cherokee.
“We’ve built dozens of 600-800 hp 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”, said company founder and president, John Hennessey.
“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.”
The tuner’s crew started out by increasing the V8’s displacement to 7.0-liters (426 cu.in.) and then added a twin turbo forced induction system, boosting output to an insane 805-horsepower and 823 lb-ft of torque, enough to propel the HPE800 from 0-60 mph in 3.1 seconds and complete the quarter mile in just 10.9 seconds with an exit speed of 130mph (209km/h).
Hennessey also upgraded transmission system and its torque converter, and added more powerful 15.1 inch Brembo brakes on all four corners.
A lowered sport suspension system, along with 20-inch light alloy wheels, a carbon fiber front splitter and a custom leather interior with Alcantara steering wheel complete the program.
All sounds good until you hear the price: HPE said it will produce 24 examples, each priced at…$235,000.
