The 2.0-liter turbocharged I-4 engine is part of the Global Medium Engine architecture family and features double overhead camshafts (DOHC), dual independent camshaft timing, and a cooled exhaust gas recirculation (C-EGR) system. This is the first time that the combined use of a twin-scroll turbocharger, C-EGR system, central direct injection and the independent liquid cooling intake of air, throttle body and turbo have been employed together. This combination of technologies enables the high levels of performance and reduces fuel consumption.

The 2.0-liter I-4 engine’s fuel pump supplies the engine’s 2,900-psi high-pressure common-rail injection system. These high pressures produce better fuel atomization and allow for more precise fuel delivery than port fuel-injected systems, according to Jeep.

The cast aluminum alloy cylinder head features a central injector and high tumble intake ports. This combination provides high charge motion and balanced air flow, according to Jeep. Integrated into the cylinder head is a water-cooled exhaust manifold to reduce emissions while providing increased engine reliability.

The 2.0-liter I-4 engine also features a low-pressure, sand cast-aluminum block with cast-in iron liner with an 84mm bore and 90mm stroke for a total displacement of 1,995cc. Cast-aluminum pistons, with a 10:1 compression ratio, have four valve pockets to accommodate the dual variable-valve timing [VVT] system. Each cylinder bore is fitted with gallery-mounted piston oil cooling jets to limit piston temperatures, reduce spark knock and increase piston durability. Select-fit main and rod bearings enable reduced clearances to help lower system oil demand and oil pumping effort. In addition, floating piston pins utilize diamond-like coating (DLC) for reduced friction.

The high-energy ignition system includes a high-energy ignition coil for better fuel efficiency. Precious-metal spark plugs with iridium and platinum provide lasting durability. Located in the center of the cam cover, the spark plugs are easily accessible when service is required. Sodium-filled exhaust valves and plasma-coated piston rings also help extend the engine’s life and bolster durability.

A variable displacement two-stage oil pump provides high oil pressure under high speed but switches to a low-pressure mode for improved fuel economy during typical driving conditions. The piston cooling is also managed by the two-stage oil pump to enhance fuel economy under normal driving conditions while improving durability under demanding, high-load engine operation. A large capacity oil cooler extends the oil change interval and ensures engine durability.

An inverted tooth primary chain drives both the intake and exhaust camshafts and minimizes noise. Camshafts are robotically assembled using hollow shafts and have polished cam journals to reduce weight and improve durability for engine stop-start operation. The use of hollow shafts provides a 3.5-lb. weight reduction when compared to an equivalent solid shaft.

Nine-speed transmission

The 2019 Jeep Cherokee benefits from an upgraded TorqueFlite nine-speed automatic transmission. The gearbox features new software that further refines drivability.

The nine-speed transmission delivers numerous benefits, including aggressive launches, smooth power delivery at highway speeds and improved fuel efficiency versus a six-speed automatic transmission, according to Jeep.

The transmission’s 4.71 first-gear ratio contributes to launch performance, while the small steps between mid-range gears ensure smoothness. Higher gears enable lower engine speeds.

Suspension & Steering

A front independent suspension with MacPherson struts and a rear independent multi-link suspension absorb on-and off-road obstacles while providing superb comfort for vehicle occupants, according to Jeep. The front suspension provides 6.7 inches of travel, while the rear suspension provides up to 7.8 inches of travel for better articulation.

The isolated rear cradle, high-strength, low-alloy front crossmember and superior torsional rigidity all contribute to the quiet, smooth ride and handling.

The 2019 Jeep Cherokee is equipped with an electronic power steering system (EPS), which improves fuel efficiency and contributes to the Jeep Cherokee’s nimbleness with a turn circle radius of more than 37 feet in 4x2 models and approximately 38 feet in 4x4 models.

With EPS, the power assist is provided via an electric motor system rather than a traditional hydraulic system. Because the system is fully electronic, the driver experiences optimal steering effort at all vehicle speeds, and there is less noise and better fuel efficiency since there is no parasitic loss from a power steering pump, according to Jeep.

This technology also enables active safety features, such as LaneSense Lane Departure Warning with Lane Keep Assist and ParkSense Parallel/Perpendicular Park Assist.

Unmatched Jeep 4x4 capability

The 2019 Jeep Cherokee highlights a choice of three innovative 4x4 systems that have been enhanced for unmatched 4x4 capability for all weather conditions. Jeep Cherokee maintains its place as the benchmark mid-size SUV with rear-axle disconnect technology that results in reduced energy loss when 4x4 capability isn’t needed, while improving fuel efficiency. The rear-axle disconnect seamlessly switches between two- and four-wheel drive for full-time torque management and does not require input from the driver.

Jeep Active Drive I

Available on the Cherokee Latitude, Latitude Plus, Limited and Overland models, Jeep Active Drive I features an all-new design for Cherokee. Jeep engineers set out to reduce weight and enhance efficiency of the next-generation rear drive module (RDM), which is fully automatic and delivers seamless operation in and out of four-wheel drive at any speed.

The result is reduced weight of nearly 17 pounds., and a reduction of low-speed system drag torque by 50 percent, which improves fuel savings, according to Jeep.

Jeep Active Drive II

Available on the Cherokee Latitude, Latitude Plus, Limited and Overland models, the re-calibrated Jeep Active Drive II includes a two-speed Power Transfer Unit (PTU) with torque management and low range. The 4-Low mode locks the front and rear driveshafts for low-speed power or towing. Low range provides a 2.92:1 gear reduction that allows for enhanced climbing ability, as well outstanding crawl ratios for severe off-road conditions.

The 2019 Jeep Cherokee with Jeep Active Drive II gives the off-road adventurer a ride height increase of 1 inch, a crawl ratio of 51:2:1 when powered by the 2-liter direct injection turbocharged inline four-cylinder engine, and a crawl ratio of 48.3:1 when powered by the 3.2-liter Pentastar V-6 engine.

The system also has a Neutral state that allows for flat-towing with all four wheels on the ground.

Jeep Active Drive Lock

Jeep Active Drive Lock includes all the features of Jeep Active Drive II and adds a locking rear differential for superior low-speed traction for severe off-road conditions. Jeep Active Drive Lock is standard on all Trailhawk models.

All 4x4 systems feature Jeep’s Selec-Terrain traction control system, which allows the driver to choose the on- and off-road setting for optimum performance. Five customized settings are offered: Auto, Snow, Sport, Sand/Mud and Rock.

Exterior

The 2019 Jeep Cherokee features an extensive new exterior design that highlights a fresh appearance, according to the company.

The Cherokee features a new fascia, lightweight hood, LED headlamps, daylight running lamps (DRL), fog lamps and liftgate.

The SUV held over its signature waterfall hood mated to the seven-slot grille. As a single piece, the sloping new lightweight aluminum hood projects clean visual lines that separate from the front fenders.

Cherokee stays true to Jeep open-air freedom by offering the dual-pane sunroof with motorized sunshade that minimizes glare.

Interior

Premium hand-sculpted forms tie signature Jeep design cues and high-quality materials together with precision craftsmanship, according to Jeep.

The use of high-gloss Piano Black is complemented by Satin Chrome tracer accents around the radio, air vent, and gear shifter bezels. Interior trim is soft to the touch. The electric park brake button has also been enclosed around the center shifter bezel for ease of operation.

The re-sculpted center console front media center hub (USB port and 115-volt outlet) has been repositioned rearward creating additional space with the enlargement of the front storage pocket, perfect for placing mobile smart phones and other devices next to the integral USB port for easy access to connected services.

Designers also freshened the interior with lighter color tones on lower trim panels that match seating.

Ergonomically designed seats support the contour of the body and are trimmed with premium cloth or Nappa leather. The seats are available as power adjustable, heated/ventilated seats with memory. The cloth fabrics include a “Hex” interlocking graphic. The available 60/40 split second-row seats adjust fore and aft for increased passenger comfort and cargo flexibility, according to Jeep.

The steering wheel is available heated, and leather-wrapped, while the front seats are heated and ventilated.

Rear cargo capacity has been increased over 3 inches in width, totally more than 27 cubic feet.

The 2019 Cherokee interior adds two new color themes, which were inspired by adventurous locations throughout the world. Available in Latitude and Latitude Plus models, the new Storm Blue interior was inspired by Iceland with its dark volcanos and black ash contrasted with blue skies. That is reflected in the black seats that are contrasted with Storm Blue stitching throughout.

Also, available on Cherokee Overland models, a new Dark Sienna interior theme offers earth tones that were inspired by the earth’s clay and outdoor freedom reflective of unmatched off-road capability that only Jeep can provide.
