Powering the 2018 Jeep Grand Cherokee Trackhawk is a supercharged 6.2-l. V-8 engine delivering 707 horsepower and 645 lb-ft of torque.

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 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 13,000 rpm.

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 optimized 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.

The 2,380-cc per revolution supercharger includes integral charge-air coolers and an integrated electronic bypass valve to regulate boost pressure to a maximum of 11.6 psi. The twin-screw rotors are specially coated with:

- A proprietary formula of polyimide and other resins;

- Nanometre-sized, wear-resistant particles;

- Solid lubricants, such as PTFE (Teflon).

The coating enables tighter clearance between the rotors. This reduces internal air leakage, delivering improved compressor performance and higher efficiencies. The coating can withstand the temperatures generated by compression, and provides superior corrosion resistance.
The supercharger is sealed for life with premium synthetic oil, uses a drive ratio of 2.36:1 and has a maximum speed of 14,600 rpm. 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.
Air sources for the supercharger include a cold-air scoop in the lower front fascia, which replaces the driver’s-side fog lamp and helps to feed the 92-millimeters throttle body.
The large-nosed crankshaft drives a high-flow gerotor oil pump, which feeds a lubrication circuit that includes eight high-flow piston-cooling jets. A high-capacity oil/air heat exchanger, mounted in the front of the Trackhawk, mitigates oil temperatures when driving conditions are harshest, such as on the track.
A new low-temperature cooling system, reservoir, heat exchanger, consisting of a pump and lines, help keep the charge air cool during performance driving. This system is designed to keep intake air temperatures below 60 degrees Celsius under extreme ambient conditions, while enabling air flow of up to 30,000 l. per minute.
A new fuel delivery system, multi-mode pumps, featuring two high-flow, matches the high-performance demands of the engine.
Upgraded driveline components, durability and refinement result in benchmark off-road performance
The performance of the 2018 Jeep Grand Cherokee Trackhawk is bolstered by various upgraded driveline components engineered to handle the additional torque output from the supercharged engine.
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, grade changes, kick-down events, longitudinal and lateral acceleration, friction detection and downshift detection to determine the appropriate shift map.
2018 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.
Standard Launch Control optimizes the Jeep Grand Cherokee 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 on the Jeep Grand Cherokee Trackhawk uses performance-tuned software to pre-configure and distinguish the five dynamic modes, Snow, Auto, Sport, Track 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 — Automatically adapts to any condition; uses a 40 % front/ 60% rear torque split;

- Sport — Transmission shift times are reduced by 50 % versus Auto Mode; stability control, four-wheel-drive and steering systems are set for typical enthusiast driving style; paddle shifters are enabled and suspension is tightened up without increasing impact harshness to deliver increased vehicle performance capability over Auto Mode; uses 35/65 torque split;

- Track — Transmission shift times are reduced 68 % versus Auto Mode to 160 milliseconds; stability control, four-wheel-drive and steering systems are set for ultimate track performance; paddle shifters are enabled and suspension is set to full firm to deliver maximum vehicle performance capability on smooth, dry surfaces; uses 30/70 torque split;

- Tow — Alters torque delivery off the line for greater smoothness and adjusts suspension to combat pitch and yaw to deliver maximum towing performance: uses 60/40 torque split;

- Snow — Maximizes traction to deliver optimized performance on snow and ice with reduced engine horsepower; uses 50/50 torque split.

Trackhawk also features a Custom Mode that allows the driver to personalize the vehicle’s performance with a selectable driving experience offering a multitude of vehicle system combinations.
The Jeep Grand Cherokee 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, 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, plus a separate toe link and a hollow stabilizer bar.
Jeep Grand Cherokee Trackhawk is capable of towing 3,266 kilograms.
