The Jeep Grand Cherokee 4xe plug-in hybrid, here in 2022, will deliver an estimated 25 miles of all-electric range and 57 miles per gallon equivalent (mpge). It will also offer 375 hp and 637Nm of torque, and a 2,720 kg towing capability.
Available in the Grand Cherokee Limited, Trailhawk, Overland, Summit and Summit Reserve, the 4xe propulsion system combines two electric motors, a 400-volt battery pack, 2.0-litre turbocharged, four-cylinder engine and TorqueFlite eight-speed automatic transmission.
The Jeep Grand Cherokee 4xe has a 400-volt, 17kWh EV battery. The battery units and controls are mounted underneath the vehicle, packaged under the floor and protected by a series of skid plates.
All high-voltage electronics are sealed and waterproof. The Trail Rated Jeep Grand Cherokee 4xe is capable of water fording up to 24 inches (61 cm).
The battery pack system includes a dedicated heating and cooling circuit to keep the battery at its optimum temperature for best performance. The system includes a dedicated heater unit and a chiller that uses the Grand Cherokee’s air-conditioning refrigerant to reduce coolant temperature when needed.
There are three E Selec modes: Hybrid, Electric and eSave, the latter including Battery Save and Battery Charge.
With 4×4 engaged, all four wheels feed torque for regenerative braking, maximising the energy recovery. Electricity from regenerative braking is fed to the battery pack to maintain or increase the state of charge.
A driver-selectable Max Regen feature deploys a more assertive regenerative braking calibration when the vehicle sees zero throttle input from the driver (coasting). Max Regen can slow the Grand Cherokee 4xe faster than standard regenerative braking and generate more electricity for the battery pack.
The Jeep Grand Cherokee has three 4×4 systems – Quadra-Trac I, Quadra-Trac II and Quadra-Drive II with rear electronic limited slip-differential (eLSD). All three systems are equipped with an active transfer case to improve traction by moving torque to work with the wheel with the most grip.
The Jeep Quadra-Lift™ air suspension, now with electronic semi-active damping, delivers up to 11.3 inches (28.7 cm) of ground clearance and 24 inches (61 cm) of water fording.
The Selec-Terrain™ traction management system lets customers choose the on or off-road setting. This feature electronically coordinates 4×4 torque split, braking and handling, steering and suspension systems, throttle control, transmission shift, transfer case, traction control, stability control, anti-lock braking system (ABS) and steering feel.
The Selec-Terrain system offers five available terrain modes (Auto, Sport, Rock, Snow, Mud/Sand) to provide optimised calibrations for any given driving scenario.
New for the 2022 model year Jeep Grand Cherokee 4×4 is front axle disconnect. If the vehicle senses that road conditions do not require all-wheel drive, the front-axle disconnect automatically places the Grand Cherokee in two-wheel drive, reducing drag on the driveline and improving fuel economy. Four-wheel drive automatically re-engages when the vehicle senses it is needed.
The all-new 2022 Jeep Grand Cherokee Trailhawk features standard 18-inch wheels with all-terrain tyres, integrated off-road camera, Quadra-Lift air suspension with up to 11.3 inches (28.7cm) of ground clearance, improved approach, departure and breakover angles and the Quadra-Drive II active transfer case with rear eLSD and Selec-Terrain.
The Grand Cherokee Trailhawk 4xe has conquered the Rubicon Trail in full-electric operation.
By 2025 Jeep plans to offer a fully electric model in every SUV segment.
