The historic firm Jeep unveils the new Plugin Hybrid Wrangler version 4xe, which also acquires an impressive technological base, which gives it unprecedented capabilities on both on- and off-road routes.
The new Plugin Hybrid Wrangler 4xe is coming on the legendary American brand’s 80th birthday to open a new chapter, which redefines the model that created the 4×4 passenger car segment.
At the heart of the Wrangler 4xe’s hybrid system are the two electric motors powered by a 400 Volt battery, which work with an efficient four-cylinder Turbo petrol engine and the TorqueFlite 8-speed automatic transmission.
The existence of the second electric motor between the petrol engine and the gearbox offers optimum architecture, so that the total output of 380 horsepower and the total torque of 637 Nm are rendered in a perfectly smooth manner, ensuring ease of driving and high performance on and off-road. In summary, the hybrid architecture of the Wrangler 4xe includes:
A first generator-electric motor located directly connected to the gasoline engine.
The second electric motor located in the automatic transmission assembly, which provides power to the system and recovers energy during deceleration. A 400 Volt lithium-ion battery pack with a capacity of 17 kWh.
The Turbo petrol engine belongs to the Global Medium Engine family of the Stellantis Group and stands out for its high technology. It has a direct injection, a twin scroll low inertia turbocharger, which is directly mounted on the cylinder head, while the set has a separate cooling system for the Turbo and air intake. All of the above ensure high performance, immediate response and low fuel consumption.
In the same area is the first high-voltage electric motor that is connected via a belt to the crankshaft of the gasoline engine, replacing the conventional alternator. In addition to the additional torque supply to the thermal motor, it undertakes the operation of the Stop&Start system in the smoothest and most direct way and supplies electricity to the battery of the hybrid system.
The second high-voltage electric motor is located in front of the transmission and replaces the classic torque converter. Depending on the driver’s preferences and driving conditions, the system allows torque to be transferred to the transmission exclusively from the second electric motor (making the Wrangler 4xe a purely electric car) or a combination of torque transfer from the petrol engine and the electric motor.
The entire hybrid mode is managed before the automatic transmission and so the advanced 4×4 system that characterizes the Wranglers is maintained in full and in the 4xe version. What changes is the overall performance and efficiency of the car, with the Wrangler 4xe delivering an acceleration of 0-100 km/h in just 6.4” while reducing emissions by 70% on the WLTP cycle compared to the conventional version.
Compared to the conventional Wrangler, the 4xe version is faster 1.2” at 0-100 km/h, has 40% more power and 60% more torque.
The second electric motor is powered by an advanced lithium-ion battery, with a capacity of 17.0 kWh, which is mounted under the rear row of seats, fully protected from the external environment, while not reducing the space available for passengers and their luggage.
For its maximum performance and durability, hybrid plugin Jeep Wrangler has a separate cooling circuit so that it always operates at the optimum temperature. Like the battery, all the electrical systems of the Wrangler 4xe have protection from water and moisture, with the model being able to comfortably overcome a water welding 76cm deep.
Hybrid: The system completely automatically combines the torque offered by the petrol engine and the two electric motors, aiming at maximum efficiency and fuel economy.
Electric: The Wrangler 4xe runs purely electric with zero emissions and almost zero noise.
eSave: The management system maintains or increases the battery charge level via the thermal motor so that electricity is available for urban travel or for purely electric off-road traffic.
The recovery system, while increasing efficiency, improves braking performance, but also helps to reduce braking system and tyre wear.
