First-ever Grand Cherokee 4xe
The all-new 2022 Jeep Grand Cherokee 4xe is the first Grand Cherokee to offer a plug-in hybrid vehicle (PHEV) variant. Its introduction signals the continued growth of the Jeep brand's electrified mission of "Zero Emission Freedom," as the brand explores future mobility during an anniversary year that celebrates 80 years of achievements, insights and innovations.
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-liter turbocharged, four-cylinder engine and TorqueFlite eight-speed automatic transmission for maximum efficiency and capability.
Overall, the 4xe system delivers 375 horsepower (280 kW) and 470 lb.-ft. (637 Nm) of torque. The Grand Cherokee 4xe, targeting an estimated 25 miles (40 km) of all-electric range, returns an estimated 57 MPGe and has an estimated total range of more than 440 miles (708 km).
The fuel-efficient 2.0-liter turbocharged I-4 engine is part of Stellantis's 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.
The conventional alternator is replaced with a high-voltage, liquid-cooled motor generator unit. Connected to the engine crankshaft pulley via a belt, the motor generator spins the engine for nearly seamless, fuel-saving, start-stop operation and generates electricity for the battery pack.
A larger high-voltage motor generator is mounted in the transmission, replacing the torque converter. Two clutches manage power and torque from the e-motor and engine.
A clutch is mounted between the engine and the motor. When the system operates in electric-only mode this clutch is open so there is no mechanical linkage between the engine and the e-motor. When the clutch is closed, combined torque from the 2.0-liter engine and the e-motor flow through the automatic transmission. A variable clutch mounted behind the e-motor manages engagement with the transmission to improve drivability and efficiency.
The 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 (ICDM) 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 battery state of charge at-a-glance during charging.
Legendary Jeep 4x4 capability
The Jeep Grand Cherokee delivers unrivaled capability along with composed on-road driving dynamics. That legendary off-road capability begins courtesy of three 4x4 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 class-exclusive Jeep Quadra-Lift air suspension, now with electronic semi-active damping, delivers up to class-leading 11.3 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, 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 optimized calibrations for any given driving scenario.
New for the 2022 Jeep Grand Cherokee 4x4 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.
Award-winning powertrains
In addition to the technologically advanced plug-in hybrid electric powertrain of the all-new Jeep Grand Cherokee 4xe, the 2022 Grand Cherokee lineup offers buyers a choice of two powerful, fuel-efficient and refined engines with proven performance for any driving situation.
Standard is the all-aluminum 3.6-liter Pentastar V-6 engine, rated at 293 horsepower and 260 lb.-ft. of torque. Lauded for its power and refinement, the 60-degree angle between the Pentastar V-6's cylinder banks make it inherently smooth running, augmented by accessories that bolt directly to the engine block.
A seven-time winner of the Wards 10 Best Engines and Propulsion Systems award, the Pentastar V-6 engine is compact, with features such as exhaust manifolds integrated into the cylinder heads. Chain-driven dual overhead camshafts include two-step variable valve lift and variable-valve timing (VVT). This combination quickly tailors the engine output to the demands of the driver for the best balance of performance and fuel economy.
Fuel-saving engine start-stop (ESS) technology is standard on the Pentastar V-6. The ESS system has been upgraded and refined for the Grand Cherokee. Changes include a pressure reserve element in the eight-speed transmission, which provides dedicated transmission fluid to the shift elements at engine restart for a quick launch. Refined powertrain controls and new starter technology minimize early engine restarts from minor movements of the driver's foot on the brake pedal. Restart noise, vibration and harshness have been reduced via revised controls and switchable engine mounts.
The 3.6-liter Pentastar V-6 engine is rated for a towing capacity of up to 6,200 pounds (2,812 kg) and an estimated class-leading driving range of more than 500 miles. VVT with dual-independent cam phasing enables better fuel efficiency across a wide torque band in the Pentastar V-6 engine. Nearly 90% of the engine's peak torque is available from 1,800 to 6,400 rpm - an important consideration when towing or hauling.
