Jeep Grand Cherokee Trackhawk from Hennessey

13 June 2017

The company Hennessey presented a package of improvements to the Jeep Grand Cherokee Trackhawk

A couple of months ago we all admired most powerful crossover – the Jeep Grand Cherokee Trackhawk. Its 700-horsepower engine is a bit of a shame almost all the competitors. Is it possible to build an SUV factory crazier Trackhawk? It appears possible, and tuning company Hennessey confirmed it.

Hennessey engineers have increased the power of the 6.2-liter HEMI with 700 HP to 1012 HP and MICRON to 1314 nm at 4200 rpm. the Main merit lies 4.5 litre supercharger, outstanding 1 bar overpressure. In addition, the "charged" Jeep Grand Cherokee Trackhawk plastic pipes was replaced with steel, optimized intake system for dynamic boost, upgraded fuel injectors, and made some other modifications. The developer of the package of improvements for "mad" "Jeep" gives a guarantee on their improvements one year or 20,000 km.

It gets really interesting when we start to study the numbers for the Jeep Grand Cherokee Trackhawk. All modifications from Hennessey model accelerates to 97 km/h in 2.8 seconds and runs the quarter mile in 10.5 seconds at speed of 214 km/h. These figures tell us not only that the Trackhawk faster than the Dodge Challenger Hellcat, but that the large SUV to sprint to keep up with the Lamborghini Huracan just one tenth of a second. For interest's sake, recall that the "standard" Jeep Grand Cherokee Trackhawk accelerates to 97 km/h "only" 3.5 seconds.

For those thousands of "horses" is too much, Hennessey offers a different package of improvements, including  the stock supercharger, but with a reduced diameter drive pulley, high performance, dynamic boost and retuned the engine control unit. This set of improvements Trackhawk will raise the capacity of its engine "only" up to 852 HP and torque to 1146 nm.

After a small shock from the numbers provided, and applause in the direction of Hennessey there is only one question: "But the transmission to the brakes do withstand such overload? And if so, for how long? Are the 20 000 km warranty mileage?". But let us leave this question on conscience of Hennessey engineers, the competence of which is reason to doubt not. We will remind, in Russia the most powerful version of the Grand Cherokee SRT with an engine producing 468 HP at a price of 5 300 000.
