After what seems like forever, it has finally happened: the quickest Jeep ever is here. The Hellcat-powered Jeep Grand Cherokee has arrived, ending one of the worst-kept secrets of all time.
Making its formal debut this week at the New York auto show, the 2018 Jeep Grand Cherokee Trackhawk has plenty to boast about as it stakes its claim on the performance mountain.
First and foremost, it has the full boat when it comes to power: yes, all 707 horsepower that the Challenger and Charger Hellcats have. There was concern in the performance community that the supercharged 6.2-liter's power output would be neutered in the Grand Cherokee due to the all-wheel-drive system's strength, but Jeep overcame that concern by modifying the full-time active transfer case with forged steel chain sprockets and a wider chain.
That transfer case is a single-speed active setup and there's an electronic limited-slip differential in the rear to help control the power.
Jeep's touting the Grand Cherokee Trackhawk as the "most powerful" and "quickest SUV ever."
With claims like 0-60 mph in just 3.5 seconds, a quarter mile time of 11.6 seconds, and a top speed of 180 mph, we aren't about to argue with them.
Of course, to handle all this power and speed, the Grand Cherokee's brake system was upgraded heavily for Trackhawk duty. With 15.75-inch two-piece vented Brembo rotors up front clamped by 6-piston calipers plus 13.78-inch vented rotors in back, Jeep claims the Trackhawk can come to a standstill from 60 mph in just 114 feet.
Many driveline components have been upgraded for Trackhawk duty, from the 8-speed automatic transmission being bolstered to a strengthened rear drive shaft and new, stronger rear axle.
Like the Grand Cherokee SRT, the all-wheel-drive system has five modes—auto, sport, track, tow, and snow. Each modifies all-wheel-drive parameters plus transmission, paddle shifters, suspension, and electronic power steering programming.
