2021 Jeep Wrangler High Altitude 4xe

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 twin-scroll, low-inertia turbocharger mounted directly to the cylinder head, along with a dedicated cooling circuit for the turbocharger, intake air and throttle body for exceptional responsiveness, performance and fuel efficiency.

A high-voltage, liquid-cooled motor generator unit mounts at the front of the engine, replacing the conventional alternator. A robust belt connects the motor generator to the engine crankshaft pulley. The motor generator spins the engine for nearly seamless, fuel-saving, start-stop operation and generates electricity for the battery pack. The Wrangler 4xe does not use a conventional 12-volt starter motor. The Wrangler 4xe is equipped with a 12-volt battery to run accessories.

The second high-voltage motor generator is mounted at the front of the transmission case, replacing the conventional torque converter of an automatic transmission.

Two clutches work to manage power and torque from the e-motor and engine. A binary clutch (on/off) is mounted between the engine and the motor. When this clutch is open there is no mechanical linkage between the engine and the e-motor, which enables it to propel the Wrangler 4xe in electric-only mode.

When the binary clutch is closed, torque from the 2.0-liter engine and the e-motor flow combine through the automatic transmission. A variable clutch mounted behind the e-motor manages engagement with the transmission to improve drivability and efficiency.

Battery Pack Preserves Interior Room

The Jeep Wrangler 4xe’s 400-volt, 17-kWh, 96-cell lithium-ion battery pack uses nickel manganese cobalt (NMC) graphite chemistry. The pack and controls mount underneath the second-row seat, where it is protected from outside elements. The Wrangler 4xe’s second-row seat is redesigned, allowing the bottom cushion to flip forward for access to the battery.

Encased in an aluminum housing, the pack is fitted 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 heater unit and a chiller that uses the Wrangler air-conditioning refrigerant to reduce coolant 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 in a single unit that is more compact than two separate components, and a next-generation Power Inverter Module (PIM) that is reduced in size. These components are housed and protected from damage in a steel structure 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 water fording up to 30 inches (76 cm).

The electric charge port features a push-open/push-close cover and is located on the left front cowl of the Wrangler 4xe for convenient nose-in parking at charging locations. The charge port includes LED indicators of charging status. An LED battery level monitor is mounted on top of the instrument panel, making it easy to check battery state of charge at a glance during charging.

Wrangler 4xe E Selec Modes

The Jeep Wrangler 4xe driver can tailor the hybrid powertrain to best suit each trip, whether it is filling the needs of most daily commuters in pure-electric operation, a night on the town or quietly exploring nature off-road.

The Wrangler 4xe 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 operates as hybrid once the battery nears its minimum state of charge.

• Hybrid: The default mode blends torque from the 2.0-liter engine and electric motor. In this mode, the powertrain will use battery power first, then add in propulsion from the 2.0-liter turbocharged I-4 when the battery reaches minimum state of charge
• Electric: The powertrain 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 2.0-liter engine
• eSave: Prioritizes propulsion from the 2.0-liter engine, saving the battery charge for later use, such as EV off-roading or urban areas where internal combustion propulsion is restricted. The driver can also choose between Battery Save and Battery Charge during eSave via the Hybrid Electric Pages in the Uconnect monitor

To help optimize the benefit of the E Selec modes, the Wrangler 4xe driver information display and the Uconnect touchscreen feature Eco Coaching Pages. The Eco Coaching Pages let owners monitor power flow and see the impact of regenerative braking, schedule charging times to take advantage of lower electric rates, and view their driving history with a detail of electric and gasoline usage.

Regenerative braking is a key part of the Wrangler 4xe eco-friendly equation. 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 Wrangler’s traditional friction brakes. The regenerative braking feature also extends the replacement period for brake pads.

With 4×4 engaged, all four wheels feed torque for regenerative braking, maximizing the 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 via a driver-selectable Max Regen feature.

When Max Regen is engaged, a more assertive regenerative braking calibration occurs when the vehicle sees zero throttle input from the driver (coasting). Max Regen can slow the Wrangler 4xe faster than standard regenerative braking and generate more electricity for the battery pack. Once selected, the Max Regen feature remains engaged until driver deselects it.

Jeep Renegade 4xe and Jeep Compass 4xe

Presented globally in March 2019 at the Geneva Motor Show, the new Renegade 4xe and Compass 4xe are the first Jeep models with plug-in hybrid electric technology available in Europe. Their arrival was celebrated in January with the exclusive First Edition – a special launch edition made available for customer previews and pre-booking on a dedicated website for select European markets. Renegade 4xe and Compass 4xe began arriving in the European market this summer. Both Renegade 4xe and Compass 4xe models feature a no-compromise hybrid solution that integrates the unmatched technical layout of each Jeep SUV and takes their capability to the next level through some of the most advanced technology, which combines enhanced performance (up to 240 horsepower), improved safety (four-wheel drive is always available) and low environmental impact (less than 50 g/km of CO2 in the hybrid mode).

The combination of a 1.3-liter turbocharged gasoline engine and the electric unit guarantees performance and extraordinary driving pleasure: acceleration from 0 to 100 km/h in less than 7.5 seconds and full electric top speed is 130 km/h, which reaches 200 km/h in the hybrid mode.

With the new hybrid technology, Jeep Renegade 4xe and Compass 4xe further improve their benchmark off-road capability courtesy of the greater torque offered by the combination between the two power sources. Thanks to the new Jeep 4xe technology, traction to the rear axle is not provided by a prop shaft, but through the dedicated electric motor. This allows the two axles to be separated and control the torque independently in a more effective way than a mechanical system, giving instant electric boost to the rear wheels when needed.

The new Jeep Renegade 4xe and Jeep Compass 4xe began arriving in Jeep dealerships across Europe this summer with a full lineup to include Limited, S and Trailhawk trims, all with four-wheel-drive configuration.
