The Jeep brand has presented its new Wrangler 4xe plug-in hybrid. Jeep Wrangler 4xe models will be available in Europe, China and the United States in early 2021. Jeep Renegade 4xe and Compass 4xe models, introduced last year in Geneva, began arriving in Europe this summer. The new Jeep 4xe models follow the introduction of the Jeep Grand Commander PHEV in China last year.
Jeep will offer electrification options on every nameplate for years to come as it strives to become the leader in premium green technology. Electrified Jeep vehicles will carry the 4xe badge.
The Wrangler 4xe’s advanced powertrain maximizes efficiency with an estimated equivalent of 50 miles per gallon (MPGe) while eliminating range anxiety, providing pure electric operation for most commutes. The Wrangler 4xe’s plug-in hybrid powertrain is capable of up to 40 kilometers of electric propulsion.
The Jeep Wrangler 4xe’s powertrain integrates two electric motors and a 400-volt battery with a fuel-efficient four-cylinder turbocharged engine and eight-speed TorqueFlite automatic transmission. This configuration maximizes the efficiency of the hybrid powertrain components and combines them with the Wrangler’s world-renowned and proven driveline.
Jeep Wrangler 4xe powertrain components. Featured components are exclusive to the Wrangler 4xe.
Key elements of the Wrangler 4xe’s powertrain include 375 horsepower (280 kW), 470 lb.-ft. (637 Nm) of torque and an estimated 50 MPGe from the following components:
- 2.0-liter turbocharged I-4
- Engine Mounted Engine Generator Unit
- Transmission-mounted engine generator unit integrated into eight-speed automatic transmission (ZF 8P75PH)
- 96-cell, 400-volt, 17 kWh lithium-ion nickel-manganese-cobalt battery pack
The 2.0-liter turbocharged I-4 engine is part of FCA’s Global Medium Engine family. The high-tech direct injection engine uses a low-inertia, dual-inlet turbocharger mounted directly to the cylinder head, along with a dedicated cooling circuit for the turbocharger, intake air, and throttle body for responsive, performance exceptional fuel efficiency.
A liquid-cooled high-voltage generator motor unit mounts to the front of the engine, replacing the conventional alternator. A robust belt connects the engine generator to the engine crankshaft pulley. The generator motor turns the engine for near-seamless start-stop operation, saving fuel and generating electricity for the battery pack. The Wrangler 4xe does not use a conventional 12-volt starter. The Wrangler 4xe is equipped with a 12-volt battery to power accessories.
The second high-voltage generator motor is mounted at the front of the transmission case, replacing the conventional torque converter in an automatic transmission.
Two clutches work to manage power and torque from the electric motor and motor. A binary clutch (on / off) is mounted between the motor and the motor. When this clutch is open, there is no mechanical connection between the motor and the electric motor, allowing you to propel the Wrangler 4xe in electric-only mode.
When the binary clutch is closed, the torque from the 2.0-liter engine and the flow from the electronic engine are combined through the automatic transmission. A variable clutch mounted behind the electronic motor manages engagement with the transmission to improve driveability and efficiency.
The Jeep Wrangler 4xe’s 96-cell, 400-volt, 17-kWh lithium-ion battery pack uses nickel-manganese-cobalt (NMC) graphite chemistry. The package and controls mount under the second row seat, where it is protected from the outside elements. The Wrangler 4xe’s second-row seat was redesigned, allowing the bottom cushion to move forward to access the battery.
Enclosed in an aluminum casing, the pack is equipped with a dedicated heating and cooling circuit to keep the battery at its optimum temperature for best performance. The temperature control circuit includes a dedicated heating unit and cooler that uses Wrangler air conditioning refrigerant to lower the refrigerant temperature when needed.
The Wrangler 4xe Hybrid System includes an Integrated Dual Charging Module (ICDM), which combines a battery charger and a DC / DC converter into a single unit that is more compact than two separate components, and a Power Inverter Module (PIM) next generation. which is reduced in size. These components are housed and protected from damage in a steel frame mounted below the battery pack.
All high voltage electronics, including the wiring between the battery pack and the electric motors, are sealed and waterproof. Like all Trail Rated Jeep Wranglers, the Wrangler 4xe is capable of wading up to 30 inches (76 cm).
The electric charging port features a push-to-open / close cover and is located on the Wrangler 4xe’s left front deck for convenient nose-in parking at charging locations. The charging port includes LED indicators for charging status. An LED battery level monitor is mounted on top of the instrument panel, making it easy to check the battery charge status at a glance while charging.
The driver of the Jeep Wrangler 4xe can tailor the hybrid powertrain to best suit every trip, whether it’s to meet the needs of most commuters on electric power, a night on the town, or leisurely exploring nature outside. road.
The Wrangler 4xe’s hybrid powertrain has three modes of operation, known as E Selec. The driver can select the desired powertrain mode via buttons mounted on the instrument panel, to the left of the steering wheel. Regardless of the mode selected, the Wrangler 4xe works as a hybrid once the battery approaches its minimum state of charge.
-
Hybrid: The default mode combines the torque of the 2.0-liter engine and the electric motor. In this mode, the powertrain will use battery power first, then add propulsion from the 2.0-liter turbocharged I-4 when the battery reaches the minimum state of charge.
-
Electric: The powertrain runs on zero-emission electric power only until the battery reaches minimum charge or the driver requests more torque (such as the throttle wide open), activating the 2.0-liter engine.
-
eSave: It prioritizes the propulsion of the 2.0-liter engine, saving battery charge for later use such as off-road vehicles or urban areas where internal combustion propulsion is restricted. The driver can also choose between Battery Saver and Battery Charge during eSave via Hybrid Electric Pages on the Uconnect monitor.
To help optimize the benefit of E Selec modes, the Wrangler 4xe Driver Information Display and Uconnect Touchscreen feature Eco Coaching Pages. Green training pages allow owners to monitor energy flow and see the impact of regenerative braking, schedule charge times to take advantage of lower electric rates, and view their driving history with detailed gas and electricity usage detail.
Regenerative braking is a key part of the Wrangler 4xe’s green equation. When the driver steps on the brake pedal, powertrain control activates the maximum available regenerative braking, up to 0.25g, from electric motors to reduce vehicle speed, augmented by traditional Wrangler friction brakes. The regenerative braking function also extends the replacement period of the brake pads.
With 4×4 activated, all four wheels feed torque for regenerative braking, maximizing energy recovery. Electricity due to regenerative braking is fed to the battery pack to maintain or increase the state of charge.
The Wrangler 4xe also features the ability to maximize regenerative energy production through a driver-selectable Max Regen feature.
When Max Regen is activated, a more assertive regenerative braking calibration occurs when the vehicle sees zero throttle input from the driver (coast). Max Regen can slow down the Wrangler 4xe faster than standard regenerative braking and generate more electricity for the battery. Once selected, the Max Regen feature remains on until the driver deselects it.
The new Jeep Wrangler 4xe is available in three models: 4xe, Sahara 4xe, and Rubicon 4xe. The Wrangler 4xe and Wrangler Sahara 4xe models are equipped with full-time 4×4 systems, next-generation front and rear Dana 44 axles and are equipped with the two-speed Selec-Trac transfer case with a low-range gear ratio of 2.72 : 1. The intuitive system allows the driver to set it and forget it in any environment.
An available Trac-Lok limited-slip rear differential provides additional grip and capacity in low-traction situations, such as driving on sand, gravel, snow or ice.
Wrangler Rubicon 4xe models carry the Rock-Trac 4×4 system including a two-speed transfer case with a 4: 1 low-range gear ratio, permanent 4×4, next-generation front and rear Dana 44 axles, electric front Tru -Lok – and rear axle lockers. The Wrangler Rubicon 4xe has an impressive 77.2: 1 crawl ratio, making it easy to climb any obstacle. Wrangler Rubicon models also offer improved articulation and full suspension travel with the help of a front axle, electronic sway bar disconnect.
The Wrangler 4xe includes Selec-Speed Control with hill climb and descent control. This allows drivers to control vehicle speed up and down on steep and bumpy slopes with the transmission shift lever.
The Jeep Wrangler 4xe will be sold globally, with electric vehicle (EV) charging port plugs tailored to specific regions. It is assembled at FCA’s Toledo Assembly Complex in Toledo, Ohio.
