The Jeep Grand Cherokee has just received a major horsepower upgrade. Called the Trackhawk, the all-new variant gets the mighty supercharged V8 derived from the Dodge Charger / Challenger Hellcat.
Billed by Jeep as the quickest and most powerful SUV ever, the 2018 Trackhawk is powered by the infamous 6.2-liter supercharged V8 that produces 719 PS and 875 Nm of torque. The engine benefits from a forged-steel crankshaft, along with forged-alloy pistons and powder-forged connecting rods.
Apart from that, the highly-tuned V8 is also fitted with an upgrade cooling system, a new fuel delivery system that has two high-flow multi-mode pumps that matches with the engine's performance and a cast iron block fitted with water jackets for optimal cooling. Power is then transferred to a Torqueflite 8-speed automatic and Quadra-tec four-wheel-drive on demand system. The rear drive shaft and rear axle have been strengthened as well to cope with the extra power, while a new four-point axle mount provides better load distribution.
0 – 97 km/h comes in at a quick 3.5 seconds while top speed is rated at 290 km/h.
Five driving modes are available in the 2018 Trackhawk which split the torque transfer between the front and rear axles. Auto adopts a 40:60 split while Sport sets the powertrain to 35:65 split. Meanwhile, Track reduces the shift times between each gear and torque split is at 30:70. The last two modes are Tow and Snow, where the former uses a 60:40 split while the latter has a 50:50 torque split.
Improved stopping power comes courtesy of Brembo. The front axle benefits from six-piston calipers with 15.75-inch discs while the rear receives four-piston calipers with smaller 13.78-inch rotors. In addition, Jeep claimed that both the anti-lock brakes (ABS), stability control (SC) and traction control (TC) have been tuned for the 2018 Trackhawk.
As for its looks, Jeep gave the Grand Cherokee Trackhawk an 'aggressive and functional' exterior. Up front, it gets the distinct seven-slot upper front grill that is flanked by adaptive bi-xenon headlights. Replacing the foglights are large air intakes which allow for better airflow and cooling. All-new 20-inch alloy wheels give the car a purposeful stance and are available either as forged aluminum or titanium. Providing grip is a set of Pirelli tires that measure 295/45.
Rounding it all up are the quad exhaust tips finished in Black Chrome and a unique rear valence painted in Gloss Black.
Inside, Jeep upholstered the Cherokee Trackhawk with Nappa leaether while soft-touch materials, and black chrome / carbon fiber trim pieces spruce up the cabin. Also present are the 7-inch driver information display on the instrument panel and the 8.4-inch touchscreen infotainment called Uconnect.
Other in-car amenities available in the new Trackhawk are: active noise cancellation, dual-screen rear entertainment, Blu-Ray support, dual-pane panoramic sunroof, paddle shifters, a Harman Kardon 19-speaker audio system and Apple CarPlay.
The 2018 Jeep Grand Cherokee Trackhawk will make its official public debut at the 2017 New York Auto Show.
