2023 Jeep Grand Cherokee 4xe

The all-new Jeep® Grand Cherokee 4xe is the first Grand Cherokee plug-in hybrid (PHEV). Its introduction signals the continued growth of the Jeep brand’s electrified mission, towards future mobility. The 4xe plug-in hybrid electric vehicle technology enhances the fun, freedom and adventure that the Jeep brand is known for, while providing unprecedented performance, fuel economy and environmental friendliness:
up to 30 miles electric range in combined cycle and 32 miles city electric range in the urban cycle
380hp combined and 637 Nm torque
Quadra Trac II or Quadra Drive II 4x4system with two-speed transfer case and 2.72:1 low-range gear ratio
47.4:1 crawl ratio
2,300 kg of max towing capability
“The new Jeep® Grand Cherokee 4xe driver can tailor its hybrid powertrain to suit each trip, from daily commuting in pure-electric mode to extended motorway road trips with no range anxiety, allowing owners to explore nature off-road in near silence,” Meunier added. “This is another important step toward achieving our global vision of Zero Emission Freedom.”
Available in Limited 4xe, Trailhawk 4xe, Overland 4xe and Summit Reserve 4xe models, the all-new Jeep® Grand Cherokee 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 for maximum efficiency and capability.
Overall, the 4xe system delivers 380 combined horsepower and 637 Nm torque, up to 30 miles electric range in combined cycle and 32 miles city electric range in the urban cycle.
The fuel-efficient 2.0-litre 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 all-new 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 Jeep® 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 61 cm.
The charge port is beneath a push-open/push-close cover on the left front wing 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.
