The Grand Cherokee 4xe’s E selec modes – hybrid, electric, and eSave – allow the 4xe driver to tailor the hybrid powertrain to best suit each trip.
The Jeep Grand Cherokee 4xe is built at the Detroit Assembly Complex – Mack plant and the Detroit Assembly Complex – Jefferson plant. Jeep Wave customer care program comes standard with all Grand Cherokee 4xe models and includes benefits such as maintenance, same-day vehicle rentals, 24/7 roadside assistance and dedicated owner support.
Grand Cherokee’s 4xe propulsion system combines two electric motors, a 400-volt battery pack, 2.0-liter turbocharged, four-cylinder engine and TorqueFlite eight-speed automatic transmission for maximum efficiency and capability.
The fuel-efficient 2.0-liter turbocharged I-4 engine is part of Stellantis Global medium engine family. The high-tech, direct-injection engine uses a twin-scroll, low-inertia turbocharger mounted directly to the cylinder head. Efficiency is enhanced via the use of electric power steering and an electrically driven air-conditioning compressor, removing those loads from the engine.
With E selec modes, the Jeep Grand Cherokee 4xe driver can tailor the hybrid powertrain to best suit each trip, whether it be commuting, off-roading or long-distance travel:
Hybrid: Blends torque from the electric motor and gas engine. The powertrain will optimize battery and engine power to deliver the best combination of fuel efficiency and performance.
Electric: Operates on zero-emission electric power only until the battery reaches the minimum charge or the driver requests more torque (such as wide-open throttle), which engages the engine.
eSave: prioritizes the engine, saving the battery charge for later use. The driver can also choose between battery save and battery charge during eSave via the hybrid electric pages in the Uconnect 5 screen.
Jeep Grand Cherokee 4xe carries a 400-volt, 17-kWh EV battery. The battery units and controls mount underneath the vehicle, packaged under the floor and protected by a series of skid plates.
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.
The Grand Cherokee’s 4xe system also includes an integrated dual charging module (IDCM) that combines a battery charger and a DC/DC converter in a single, compact unit and a power inverter module (PIM) that is reduced in size. These are mounted under the body and protected with steel shields.
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 charge port is beneath a push-open/push-close cover on the left front fender for convenient nose-in parking at charging locations. The charge port includes LED indicators of charging status. An LED battery level monitor sits on top of the instrument panel, making it easy to check the state of the battery charge at a glance.
The driver information display and main Uconnect touchscreen include Eco Coaching Pages. The Eco Coaching Pages let owners monitor power flow and see the impact of regenerative braking, as well as view their driving history with a detail of electric and gasoline usage.
Regenerative braking is part of the 4xe system. When the driver steps on the brake pedal, the powertrain control engages the maximum available regenerative braking, up to 0.25 g, from the electric motors to slow the vehicle, augmented with the Grand Cherokee 4xe’s traditional friction brakes.
With 4x4 engaged, all four wheels feed torque for regenerative braking, maximizing 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.
Jeep Grand Cherokee 4xe delivers unrivaled capability along with composed on-road driving dynamics. That legendary off-road capability begins courtesy of two 4x4 systems – Quadra-Trac II and Quadra-Drive II with rear ELSD. Both systems are equipped with an active transfer case to improve traction by moving torque to work with the wheel with the most grip.
The class-exclusive Jeep Quadra-Lift air suspension, now with electronic semi-active damping, delivers up to 10.9 inches (28.7 cm) of ground clearance and 24 inches (61 cm) of water fording. The system automatically adjusts the shock tuning to changing road conditions for enhanced comfort, stability and control, or may be controlled manually with console controls, and features five height settings for optimum ride performance.
The class-leading selec-terrain traction management system lets customers choose the on- or off-road setting for optimum 4x4 performance. This feature electronically coordinates 4x4 torque split, braking and handling, steering and suspension systems, throttle control, transmission shift, transfer case, traction control, stability control, antilock brake system (ABS) and steering feel.
The selec-terrain system offers five available terrain modes (auto, sport, rock, snow, mud/sand) to provide optimized calibrations for any given driving scenario.
Jeep Grand Cherokee 4xe features 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.
A lowered, tapered roof improves the Grand Cherokee 4xe’s aerodynamic performance and efficiency without sacrificing cargo spaciousness and utility, while the lowered beltline and expansive glass allow more light into the cabin and increase outward visibility.
