Jeep Cherokee 2019 4WD System Explained – Video

Jeep Cherokee 2019 4WD System Explained – Video

The 2019 Jeep Cherokee highlights a choice of three innovative 4×4 systems that have been enhanced for unmatched 4×4 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 4×4 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 of this new state-of-the-art technology is reduced weight of nearly 17 lbs., and a reduction of low-speed system drag torque by 50 percent, which improves fuel savings. The system does not require any driver intervention or feedback, delivers yaw correction during dynamic events, and improves during both understeer and oversteer conditions.

 

 

Jeep Active Drive II
Available on the Cherokee Latitude, Latitude Plus, Limited and Overland models, the recalibrated 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 one inch, a crawl ratio of 51:2:1 when powered by the 2.0-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. Also, the system 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 4×4 systems feature the Jeep brand’s renowned 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. Through the use of algorithms that enable unsurpassed control and capability, Selec-Terrain electronically coordinates and optimizes up to 12 systems on any terrain, providing enhanced vehicle control including: drivetrain control module, electronic brake controller, electronic stability control (ESC), transmission controller, powertrain controller and Selec-Speed Control (Hill-ascent and Hill-descent Control).
