The Jeep Grand Cherokee Trackhawk is one of the fastest SUVs out there. It may lack the off-road capabilities of its underpowered version, but it makes up for it through the grunts. After all, it packs a Hellcat engine under its hood.
At 707 horsepower (527 kilowatts) and 645 pound-feet (875 Newton-meters) of torque, you wouldn’t call the Grand Cherokee Trackhawk underpowered. Its supercharged 6.2-liter HEMI V8 can propel the 5,363 lbs (2,432 kg) SUV to 60 mph (97 km/h) in about 3.5 seconds. That said, there are still people out there who think that number is too slow.
One of them is Mike Ferrand from the Sinister Performance Club. Its Grand Cherokee Trackhawk produces approximately 1,300 horsepower (956 kilowatts) and 1,500 pound-feet (2,033 Newton-meters) of torque. Thanks to the added boost, Mike’s tuned Trackhawk is the fastest in Canada and the second fastest in the world.
According to Mike, the engine is tuned for nitrous and features improved blowers and billet bearing plates. The Jeep also has ported top and bottom ends, plus 1,300 cc injectors. Reinforced pistons and rods, along with an eight-speed automatic transmission. Last but not least, the axle gets an upgrade to cope with the massive power boost. Surprisingly, most of the engine’s internals remain. What’s even more surprising is that it still uses the standard driveshaft.
Video from That Racing Channel shows it takes effort to wrestle the SUV in a straight line. It also shows the brutal launch this tuned Trackhawk is capable of even without nitrous activated. Turning it on, the 5,500 lb SUV dashes away from rest like a radio controlled car.
In 2020, the Jeep pulled a quarter-mile time of 9.55 and clocked in at 143 mph. For reference, the world record is 9.48 seconds, so Mike is not far from matching it. Not only that, it can run from 0 to 60 mph in two seconds, and is certified by GPS. In other words, it’s several hundred away from a matching Tesla Model S Plaid. That’s not bad for an SUV with a well-equipped interior. If anything, the potential for tuning the Trackhawk makes us sad to hear reports that there won’t be a second-generation version on the horizon.
