2018 Jeep Grand Cherokee Trackhawk
This year is truly the year of power for automobiles. Dodge introduced the Durango SRT and then Dodge Challenger SRT Demon opened the gates of Hell, and now Jeep® has put a Hellcat engine in its own Jeep Grand Cherokee called the Jeep Grand Cherokee Trackhawk.
Supercharged 6.2-liter HEMI SRT V8
Avail. Engine Type
There is only one engine that could power the Jeep Grand Cherokee Trackhawk, and that’s the same supercharged 6.2-liter HEMI SRT V8 engine found under the hood of the Dodge Charger and Challenger SRT Hellcat models. Capable of generating 707 horsepower and 645 lb-ft of torque, it’s paired to an upgraded eight-speed TorqueFlite automatic transmission. With a top g-force of 0.88 G’s, the Grand Cherokee Trackhawk can accelerate from 0-60 mph in 3.5 seconds, and although yet to be tested, is theorized to be able to cover a quarter-mile in 11.6 seconds.
The Grand Cherokee Trackhawk comes standard with an all-wheel drivetrain. This can be controlled via the Jeep Quadra-Trac on-demand four-wheel drive system with an active transfer case and rear differential with an electronically controlled limited-slip unit. All of this power is controlled by refined engineering.
The Jeep Grand Cherokee Trackhawk is a little different than other Jeep Grand Cherokee trims. Made with Hellcat muscle, several components have popped up. Namely, a Torque Reserve launch-control feature that keeps the supercharger valve closed and cuts the spark and fuel to several cylinders in the engine to limit the torque before the brake is released for launch. To keep the vehicle in check, it has been built with a cast iron engine block, a forged-steel crankshaft with a damper, pistons made from a high-strength forged-alloy, and cylinder heads optimized for superior thermal conductivity.
There is also an upgraded suspension on the Trackhawk and the appropriate brake system. Like many high-performance muscle cars, it comes with a high performance Brembo brake system, made up of two-piece front rotors and six-piston calipers. That system can bring a Grand Cherokee Trackhawk going 60 mph to a stop in 114 feet.
Although one-of-a-kind, Jeep didn’t do a whole lot to change the look of the Grand Cherokee for the Trackhawk. With a rear spoiler and aerodynamic lines, the vehicle has a bit of style to it, but the real differences are simple aesthetics. Air vents have been integrated into the front fascia to feed the supercharger air, and four-inch black chrome quad exhaust tips are in the rear. Aside from that, there’s respective badges such as “Supercharged” and “Trackhawk.”
The inside has a bit more of a change, beginning with Nappa leather and suede upholstery embroidered with the “Trackhawk” logo. The cabin is covered with a premium soft-touch surface and light black chrome accents. The front seats are heated and ventilated, and the rear seats are also heated. A winged Trackhawk badge can be found on the steering wheel, the console comes with a stitched-leather dashboard and door-panel coverings, Berber carpets, and a wide array of new instrumentation.
The sound system hasn’t been detailed yet, but one could assume it would have the high-end Harman Kardon 19 speaker sound system with subwoofer, or at least 9 amplified speaker sound system. Uconnect, most likely 8.4 NAV is installed, with Apple CarPlay and Android Auto. A rear entertainment system with a Blu-ray dual screen is an option to add-on. When it comes to a performance vehicle like this, one system is definitely going to pop up - Uconnect Performance Pages to display readouts of horsepower, track records, G-force, and various modes via Selec-Track – Auto, Sport, Track, Tow, and Snow. Drivers can also save recordings of their performance with a new snapshot function.
With all that power, the Jeep Grand Cherokee has plenty of safety features to keep it in check. Standard features include adaptive cruise control with stopping functions, advanced brake assist, blind-spot monitoring with rear cross-traffic alert, full-speed forward collision warning with crash mitigation, lane departure warning, and front and rear park assist. To keep someone going for a joy ride or lending the Trackhawk out to an inexperienced driver, a coded security setting can be programmed to reduce engine power, disable launch control, and lock out first gear.
Jeep vehicles come with a 3-year or 36,000-mile basic warranty, a 5-year or 100,000-mile powertrain warranty, roadside assistance for five years or 100,000 miles, and rust-through coverage for five years or 100,000 miles.
