Imagine what it can do when tuned.
John Hennessey describes the new Jeep Grand Cherokee Trackhawk as “automotive ridiculousness.” Hennessey, the Texan who gave the world the Venom GT and plenty of even more powerful versions of our favorite muscle cars, is calling something stock “ridiculousness.” And let’s not forget about the trucks, such as the insane VelociRaptor 6x6, he’s built as well. There’s also the upcoming Venom F5 hypercar. Point being, Hennessey’s horsepower credentials are solid, and yet he’s blown away by something coming straight from the factory.
Imagine what he and his crew can do to make the Grand Cherokee Trackhawk even more powerful. But for today, Hennessey is here to demonstrate what this “big shoebox with wheels” can do. Jeep claims this thing can do a maximum speed of 180 mph, which is already faster than most sports cars.
So Hennessey takes it to his own test track and guns it, and it just pulls and pulls. It keeps pulling all the way to 140 mph where and remains completely stable the entire time. In the end, it managed to hit 175 mph, but the last 35 mph came much slower. Why didn’t it hit 180 mph? Probably because this particular Grand Cherokee Trackhawk still has not passed its engine break-in period; there’s only 92 miles on its clock. Give it more time and that 180 mph is surely doable. But still, 0-60 mph in just 3.5 seconds (watch the video and time it yourself) is unreal for a vehicle of this size and weight. Then again, it’s got 707 hp and 645 lb-ft of torque and all-wheel drive at its disposal.
And if you think this SUV can’t get any faster, think again. Hennessey has already announced plans for a 1,012 hp upgrade package, increasing torque to 969 lb-ft. We can’t wait to see that on the straightaway.
