The new Jeep Wrangler 4xe has a plug-in hybrid powertrain which offers an electric driving range of 31 miles in the urban WLTP cycle and it can operate in four-wheel drive in full-electric mode.
The Wrangler 4xe plug-in hybrid has two electric motor generators and a high-voltage battery pack, with a turbocharged 2.0-litre petrol engine and TorqueFlite eight-speed automatic transmission. The Wrangler 4xe delivers a combined output of 380hp and 637Nm of torque and can accelerate from zero to 62 mph in 6.4 seconds.
The Wrangler 4xe plug-in hybrid offers two four-wheel drive, active, on-demand full time systems (Selec-Trac or Rock-Trac), next-generation Dana axles, Tru-Lok electric front- and rear-axle lockers, Trac-Lok limited slip differential and electronic front sway-bar disconnect.
A full battery recharge is available in less than three hours using a 7.4 kWh Wallbox.
The new Wrangler 4xe plug-in hybrid is available in three trim levels – Sahara 4xe, Rubicon 4xe and the exclusive 4xe 80th Anniversary special edition; with two 4×4 systems; and 17 and 18-inch alloy wheels.
All colour options can be combined with the choice of soft top, hard top, power soft top and dual top roof configurations.
All high-voltage electronic components and systems, including the wiring between the battery pack and e-motors, are sealed and waterproofed. Just like all Trail Rated Jeep Wrangler models, the 4xe variant is capable of water fording up to 760mm.
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 dashboard, to the left of the steering wheel.
• Hybrid: The default mode that blends torque from the 2.0-litre engine and electric motors. In this mode the powertrain will use battery power first, then when the battery reaches its minimum state of charge, or the driver requests more torque, it will use the propulsion from the 2.0-litre turbocharged I-4
• Electric: The engine operates on zero-emission electric power until the battery reaches the minimum charge level, or the driver requests maximum torque (such as wide-open throttle), which engages the 2.0-litre engine. If the battery level is at its lowest, the system automatically switches back to Hybrid mode.
• E-Save: This mode prioritises propulsion from the 2.0-litre petrol engine, saving the battery charge for later use, such as all-electric off-road driving or for when entering urban areas. The driver can choose between two modes, known as Battery Save and Battery Charge during E-Save, both of which can be activated from the Uconnect screen:
o Battery Save: maintains battery charge level for later use and predominantly uses the internal combustion engine
o Battery Charge: charges the battery up to 80% using the internal combustion engine, acted on by the combined electric generator
With 4×4 engaged, all four wheels feed torque for regenerative braking, maximising the energy recovery. The electricity due to regenerative braking is accumulated in the battery pack to maintain or increase the state of charge.
The Wrangler 4xe also features the ability to maximise regenerative energy production via a driver-selectable Max Regen feature.
When Max Regen is engaged via the button on the centre console (a blue LED light shows it is on), 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.
All Jeep Wrangler 4xe models are equipped with full-time active on-demand 4×4 systems: Selec-Trac on the Sahara 4xe and 80th Anniversary 4xe trims, and Rock-Trac on the Rubicon 4xe, the most capable version for off-road driving. Both operate in four driving modes (plus Neutral mode):
• 2H (Two-Wheel Drive High Range)
• 4H AUTO (Full-Time Active On-Demand Four-wheel drive High range)
• 4H Part-Time (Part-Time Four-wheel drive High range)
• 4L (four-wheel drive low-range)
When the drivetrain is shifted to four-wheel drive low-range (4L), all Wrangler 4xe power modes are available – Hybrid, Electric and E-Save.
The instant availability of torque from the electric motor in the Wrangler 4xe delivers a more precise and controlled driving experience for climbing and crawling.
The car’s ‘Trail Rated’ technical features include two advanced full-time active on-demand 4×4 systems – Selec-Trac or Rock Trac, next-generation Dana axles, Tru-Lock electric front and rear-axle lockers, Trac-Lok limited slip differential and electronic front sway-bar disconnect.
In full electric mode, the Wrangler 4xe uses four-wheel-drive to deliver off-road performance.
Jeep Wrangler Sahara 4xe is fitted with Selec-Trac full-time active on-demand four-wheel drive system, with a two-speed transfer case, with a 2.72:1 low-range gear ratio, and Dana 44 front and rear axles.
A Trac-Lok limited-slip rear differential – standard on the Sahara trim – also provides extra grip and capability during slippery, low-traction situations, such as driving on wet tarmac with rain, ice or snow, or over trails with sand and gravel.
Jeep Wrangler 4xe Rubicon models carry the Rock-Trac full-time four-wheel drive system that includes a two-speed transfer case with a 4:1 low-range gear ratio, front and rear next-generation Dana 44 axles, and Tru-Lok electric front and rear-axle lockers for extreme off-road driving. The Wrangler Rubicon 4xe has a crawl ratio of 77.2:1, which makes scaling any obstacle easy.
The Rubicon trim also offers improved articulation and total suspension travel thanks to its front axle, electronic sway-bar disconnect. This system makes it possible to disconnect the front sway bar to increase suspension travel and better tackle particularly challenging obstacles.
The Wrangler 4xe includes Selec-Speed Control with Hill Ascent and Hill Descent Control. This allows drivers to control pre-set vehicle speed up and down steep, rugged grades with the transmission shift lever when driving off-road.
Like every Jeep Wrangler, the 4xe models wear the ‘Trail Rated’ badge, attesting to its legendary 4×4 capability. Trail Rated performance is the result of a series of heavy tests performed in the following areas: traction, water fording manoeuvrability, articulation and ground clearance.
The new Trail Rated capability of the Wrangler 4xe is guaranteed by equipment that includes:
• Selec-Trac 4×4 system with “4LO” mode, a 2.72:1 crawl ratio (standard on Sahara 4xe);Rock-Trac 4×4 system with “4LO” mode, a 4:1 low-range gear ratio and Tru-Lok electric lockers (standard on the Rubicon 4xe)
• Skid plates and rear tow hook
• Benchmark angles in its class: on the Rubicon 4xe, approach angle of 36.6 degrees, breakover angle of 21.4 degrees, departure angle of 31.8 degrees, and ground clearance of 25.3cm
• 17-inch off-road wheels with 32-inch Mud Terrain tyres (Rubicon 4xe) and 18-inch wheels with All Season tyres (Sahara 4xe and 80th Anniversary 4xe trims)
• Water fording up to 76cm
There’s a new forward-facing camera (standard on Rubicon and available on Sahara and 80th Anniversary) which can be operated through the Uconnect display and adds to the safety offered by the Wrangler when driving off-road but also on everyday journeys in the city. It includes a self-cleaning function, which is activated via the radio menu.
The first electrified Wrangler is available in two trim levels, Wrangler Sahara 4xe and Wrangler Rubicon 4xe, plus the exclusive “80th Anniversary” special-edition model.
To make open air driving even more unique and extreme, half-doors are available for the first time on the Sahara and Rubicon trims as official accessories. Half doors add to the open air driving options provided by the standard foldable windscreen, removable doors and various top combinations.
