On the heels of rolling out the 840 horsepower Challenger SRT Demon Jeep has now introduced the 707 horsepower, supercharged 6.2-liter V-8 engine powered 2018 Jeep Grand Cherokee Trackhawk.
Add a TorqueFlite eight-speed automatic transmission to get things going and Brembo brakes to slow everything down and the Grand Cherokee Trackhawk can go 0-60 mph in 3.5 seconds, quarter mile in 11.6 seconds at 116 mph, top speed of 180 mph, 60-0 mph braking distance in 114 feet and .88g capability on the skid pad.
“Long recognized as the full-size SUV capability leader, Jeep Grand Cherokee is now the most powerful and quickest SUV as well, with the introduction of our new 707-horsepower Trackhawk,” said Mike Manley, Head of Jeep Brand – FCA Global. “The new Grand Cherokee Trackhawk delivers astounding performance numbers, backed by renowned SRT engineering that combines world-class on-road driving dynamics with luxury, refinement and an array of innovative advanced technology.”
The standard TorqueFlite eight-speed automatic transmission software takes into account variables such as engine torque gradients, kick-down events, longitudinal and lateral acceleration, grade changes, friction detection and downshift detection to determine the appropriate shift map. The Quadra-Trac on-demand four-wheel-drive system includes an electronic limited-slip rear differential and a single-speed active transfer case. The new, full-time active transfer case uses forged steel chain sprockets and a wider chain for added strength and durability.
Standard Launch Control optimizes Trackhawk’s performance by coordinating the engine, transmission, driveline and suspension for a textbook launch and consistent straight-line acceleration. A new standard Torque Reserve system provides improved engine torque response and quicker vehicle acceleration in Launch Control by pre-positioning the supercharger bypass valve to generate boost and minimize manifold filling time, while cutting fueling to individual cylinders and managing spark timing. This generates a reserve of torque that can be instantaneously delivered upon acceleration from a standing stop.
The Selec-Track system uses performance-tuned software to pre-configure and distinguish the five dynamic modes, including: Auto, Sport, Track, Snow and Tow, enabling drivers to choose a vehicle setting that ideally meets their requirements and ambient conditions. The drive modes separately control the four-wheel-drive system, transmission, paddle shifters, suspension and the electric power steering.
Trackhawk rides on a short- and long-arm (SLA) independent front suspension with coil springs, Bilstein adaptive damping suspension (ADS), upper- and aluminum lower-control arms (“A” arms), aluminum knuckle, aluminum clevis and hollow stabilizer bar. The rear suspension is a multi-link design with coil spring, Bilstein ADS, aluminum lower control arm, independent upper links (tension and camber), plus a separate toe link, and a hollow stabilizer bar. Trackhawk is capable of towing 7,200 pounds.
Trackhawk rides one inch lower than non-SRT Grand Cherokee models and is further set apart with body-colored wheel flares, side sill cladding and a sculpted hood with dual heat extractors. The signature seven-slot upper front grille is flanked by adaptive, bi-xenon headlamps and surrounded by an LED character lamp treatment. The headlamps on the Trackhawk model feature a unique Gloss Black background to accent their jewel-like appearance. The fog lights are absent from the Trackhawk’s front fascia to optimize airflow to cooling modules and air induction without compromising the vehicle’s balance.
From behind, the Grand Cherokee Trackhawk features a Gloss Black rear valence that showcases four-inch Black Chrome quad exhaust tips. The new quad exhaust system design provides an exhilarating and unmistakable note during maximum acceleration.
A “Supercharged” badge on both front doors and a Trackhawk badge on the liftgate features a Liquid Titanium Chrome outline and Matte Black background.
New standard 20 x 10-inch Titanium wheels with a Satin Chrome center cap showcase the distinctive yellow calipers underneath. Available lightweight 20 x 10-inch forged aluminum Low Gloss Black wheels save 12 pounds versus the standard Trackhawk wheel. Grand Cherokee Trackhawk also features all-new Pirelli 295/45ZR20 Scorpion Verde All-Season and new Pirelli P Zero three-season tires with an increased speed rating.
The instrument panel center stack features an 8.4-inch Uconnect touchscreen with Trackhawk-exclusive Performance Pages that showcase an array of performance timers and gauge readouts, including a new engine dynamometer screen that measures instantaneous horsepower, torque and current transmission gear. The dynamometer screen also includes a new snapshot function for owners to save their readouts on a USB. There is also a three-spoke steering wheel with a flat bottom features a bevy of comfort, convenience and connectivity controls and ergonomically efficient paddle shifters.
The Trackhawk features standard Nappa leather and suede seats with an embroidered “Trackhawk” logo. A fully wrapped Signature Leather Interior Package with “Trackhawk” embossed on the seats, optional in black and Trackhawk-exclusive black and Dark Ruby Red is available. Seats are also heated (front and rear) and ventilated (front). Dark Ruby Red seatbelts and a dual-pane panoramic sunroof are also available options.
Jeep Grand Cherokee Trackhawk is available in nine exterior colors: Billet Silver, Granite Crystal, Diamond Black, Ivory Tri-coat, Bright White, Velvet Red, Rhino (exclusive), Redline 2 (exclusive) and True Blue.
Built in Detroit at the Jefferson North Assembly Plant, the 2018 Grand Cherokee Trackhawk will arrive in Jeep showrooms in the fourth quarter of 2017. No pricing information was available.
