Santa’s new Twin-Turbo HPE800 Jeep SRT-8 Sled by Hennessey Performance

The 800 horsepower sleigh.

Hennessey Performance has a long history of creating high-horsepower forced-induction systems for a variety of sports cars. The latest to receive the twin-turbocharger treatment is the 2013 Jeep Grand Cherokee SRT-8, and it packs a punch.

The Henessey Performance twin turbo Jeep Grand Cherokee SRT-8 is a four-wheel drive monster. The US-based tuner developed and installed a new HPE800 upgrade program for the Jeep, turning it into super SUV. As part of the HPE800 package, the stock 6.4-liter V-8 engine grows in displacement up to 7.0 liters (426 cu. in.) and is fitted with a twin-turbocharger system. The upgrades increase output to a whopping 805 bhp at 5,800 RPM and 823 lb-ft. of torque at 4,000 RPM, sending the SUV to 60 mph in just 3.1 seconds and to a through the ¼ mile in 10.9 seconds at 130 mph.

In order to handle the extreme power from the upgraded engine, the Jeep HPE800 kit comes with a transmission and torque converter upgrade. New six-piston front and four-piston rear Brembo brakes are installed along with lightweight 20-inch alloy wheels, a lowered suspension, and carbon fiber front spoiler lip for stability and performance.

The Hennessey Performance twin turbo 2013 Jeep Grand Cherokee SRT-8 also comes standard with a complete leather interior with alcantara steering wheel and serial numbered dashboard plaque.

Only 24 examples of the Hennessey Performance HPE800 Jeep Grand Cherokee SRT-8 models will be produced. Pricing for each model will begin at $235,000.
