Trackhawk turns heads

The breakthrough supercharged engine is designed and manufactured using only the strongest and most durable materials. Its cast iron block features water jackets between the cylinders for optimal cooling.

A forged-steel crankshaft with induction-hardened bearing surfaces is so strong it can withstand firing pressures of nearly 110 bar (1 600 psi) – the equivalent of five family sedans standing on each piston, every two revolutions. The unique, specially tuned crankshaft damper has been burst tested to 13 000r/min.

High-strength, forged-alloy pistons – developed using advanced telemetry measurement – are coupled to powder-forged connecting rods with high-load-capacity bushings and diamond-like, carbon-coated piston pins.

Premium grade, heat-treated aluminum-alloy cylinder heads are optimised for superior thermal conductivity. Sodium-cooled exhaust valves feature hollow-stem construction and special steel-alloy heads that stand up to temperatures as high as 900 degrees Celsius (1 652 degrees Fahrenheit).

The supercharger is sealed for life with premium synthetic oil, uses a drive ratio of 2.36:1 and has a maximum speed of 14 600r/min. The supercharger drive system’s one-way clutch de-coupler improves refinement, while allowing for precisely the kind of powerful sound certain to captivate Jeep Grand Cherokee Trackhawk drivers.

The standard TorqueFlite eight-speed automatic transmission delivers improved shift response, quality and consistent performance and drivability. The 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 Jeep Grand Cherokee Trackhawk is equipped with the Jeep Quadra-Trac on-demand four-wheel-drive system, which 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.

A strengthened rear drive shaft connects to a new, stronger rear axle. The differential features a revised housing design, revised ring-and-pinion tooth geometry and new four-point axle mounting scheme for better load distribution, additional torque capacity and overall durability. Torque is delivered to the rear wheels via new ultra-high-strength 300M low-alloy vacuum melted steel half-shafts with upgraded eight-ball outboard constant velocity joints.

Launch Control, fitted as standard, optimises the Jeep Grand Cherokee Trackhawk’s performance by coordinating the engine, transmission, driveline and suspension for a textbook launch and consistent straight-line acceleration.

The Selec-Track system on the Jeep Grand Cherokee Trackhawk 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.

Dynamic drive mode configurations include: Auto, Sport, Track, Tow and Snow programmes to make just about unstoppable.

New benchmark SUV stopping performance
New high-performance Brembo brakes include the largest standard front brakes ever offered on a Jeep vehicle. Up front are 400mm two-piece vented rotors with six-piston calipers painted with a new distinctive yellow finish, and 350mm vented rotors with four-piston yellow calipers in the rear.

The new Brembo brakes bring the Jeep Grand Cherokee Trackhawk to a stop from 100km/h in 35m. For added safety, the anti-lock braking, electronic stability control and traction systems are uniquely tuned.

High-performance, racing-inspired interior
The driver-focused interior features premium soft-touch materials, unique Light Black Chrome finishes and carbon fiber spears, and a 7″ driver information display (DID) instrument cluster.

The instrument panel center stack with new 8,4″ Uconnect touchscreen features 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 Jeep Grand Cherokee Trackhawk’s three-spoke steering wheel with a flat bottom features a bevy of comfort, convenience and connectivity controls and ergonomically efficient paddle shifters.

There is also a 825W Harman Kardon high-performance audio system with 19-speakers and two subwoofers.

Safety and Security
The Jeep Grand Cherokee Trackhawk includes more than 70 safety and security features, including Trailer Hitch Camera View at Speed, which allows owners to view trailered items through the rear-mounted camera while moving, and a Valet mode that enables the various vehicle configurations.

Other prominent, standard Jeep Grand Cherokee Trackhawk safety and security features include Adaptive Cruise Control with Stop; Advanced Brake Assist; Blind-spot Monitoring with Rear Cross Path Detection; Full-speed Forward Collision Warning with Crash Mitigation; Front and Rear Park Assist; Lane Departure Warning-Plus; Ready Alert Braking and SiriusXM Guardian and Roadside Assistance buttons.

Advanced technology delivered with all-new infotainment system
The Jeep Grand Cherokee Trackhawk is equipped with standard Apple CarPlay and Android Auto through the latest version of Uconnect’s 8,4″ touchscreen radio system.

The latest Uconnect operating system includes easy-to-use features, pinch-to-zoom display, enhanced processing power, faster startup times and touchscreens that display high-resolution graphics. Drivers and passengers also have an abundance of infotainment features at their fingertips with SiriusXM Radio, Travel Link, Traffic and Guardian Connected Services that provide real-time information.
