Traction control system
Jeep Selec-Terrain traction control system manages the AWD system on Renegade 4xe by combining the five dynamic modes – Auto, Sport, Mud/Sand, Snow and Rock – in to two different 4×4 traction modes, depending on the situation that needs to be tackled.
4WD Lock permanently engages the four-wheel drive at speeds up to 9mph, keeping the rear electric motor (P4) constantly running to provide 4×4 traction at low speeds with a constant distribution of torque between the two axles (the distribution ratio varies depending on the selected Terrain mode).
This 2021 Jeep Renegade architecture provides two cars in one: a battery electric vehicle featuring an electric motor and a high-voltage lithium-ion battery pack on the rear axle and a conventional vehicle with an internal combustion engine fitted on the front axle.
Electric driving modes
Passive E-SAVE or Battery Save maintains the state of charge of the battery through the predominant use of the internal combustion engine
E-SAVE active or Battery Charge charges the battery up to 80% through the operation of the internal combustion engine on which the combined front electric generator acts
The combination of an internal combustion engine and the electric units guarantees performance and maximum driving pleasure, with acceleration from zero to 62mph in around 7.5 seconds and a top speed of 81mph in full electric and up to 124mph in hybrid mode.
This ensures that the front electric motor, mechanically connected to the internal combustion engine, continuously generates high-voltage current to power the rear electric motor and deliver maximum traction regardless of the state of charge of the battery.
Electric Charging options
Charging the new 2021 Jeep Renegade 4xe is simple and user-friendly with seamless integration between smartphone and the Uconnect system 8.4-inch touchscreen, to manage charging according to the customers’ specific requirements and lifestyle.
When additional speed and power is needed the Jeep Renegade 4xe automatically starts the internal combustion engine on the front axle, which drives the front wheels and turns the vehicle into an eAWD, that is an all-wheel-drive car that is also a hybrid.
The Renegade 4xe also feature a new six-speed automatic transmission selector, updated Selec-Terrain rotary control with eAWD modes (4WD Lock, 4WD Low, Hill Descent Control) to engage the different driving modes – Auto, Snow, Mud & Sand, and Rock – including the new Sport mode for enhanced throttle response and steering.
When the battery charge level is low, the internal combustion engine is switched on to provide the required torque to the front wheels, making up for the lack of electric propulsion from the rear wheels.
Engine, Power and performance
The Jeep Renegade 4xe pairs a 1.3-litre turbo petrol engine with an electric motor, located between the rear axle, which is powered by an 11.4 kWh battery that can be recharged while driving or through an external power outlet or charge point.In HYBRID mode – the optimisation algorithm (HCP) guarantees system efficiency by modulating the joint intervention of the electric motors and internal combustion engine, according to the charge level of the battery.The 4xe driving experience
Electric Driving experience
The Jeep Renegade 4xe electric driving experience starts when the customer parks the car in the garage and leaves it plugged into the normal domestic socket using the supplied cable, or connected to the handy easyWallbox charger the evening before. Additionally, the Renegade 4xe travels in hybrid mode when the battery reaches the minimum charge level, regardless of the selected mode.
The plug-in hybrid traction system is even more powerful in terms of 4WD capability than a vehicle with a conventional internal combustion engine.
This function maintains the remaining battery life by using the internal combustion engine to charge the battery through the electric motor-generator unit mounted on the front axle. It will be the most fuel-efficient Jeep SUV ever, with the new 4xe technology offering zero tailpipe-emission in full electric mode.
The second option, Battery Charge, uses the internal combustion engine to recharge the battery up to 80%.
Key elements of the Renegade and Compass 4xe powertrain are:
- A 1.3-litre, four-cylinder, turbo petrol internal combustion engine delivering 130hp or 180hp and 270Nm of torque.
- Energy level (State Of Charge) of the battery pack
- Electric motor and internal combustion engine efficiency maps
- New for the Renegade 4xe, this dynamic driving mode makes the daily urban driving experience more enjoyable, by tightening up the steering, sharpening the throttle response and adjusting the behavior of the transmission, with higher upshifts for full power and torque delivery
The Jeep Renegade 4xe powertrain integrates two electric motors and an 11.4 kWh battery pack, with a fuel-efficient 1.3-litre turbo petrol engine and six-speed automatic transmission.At the same time, it is ideal for everyday driving in the city, thanks to the plug-in hybrid system that allows it to travel with zero tailpipe emissions for a range of up to 26 miles in full-electric mode.The increased torque generated by the electric motor and the ability to adjust it with extreme precision ensures even greater four-wheel-drive capability on any terrain, for extreme off-road adventures.
E-SAVE is the mode for maintaining battery charge or for charging it while driving using the internal combustion engine. The new plug-in hybrid electric technology elevates the capability of the Jeep Renegade by increasing off-road prowess, while also enhancing its on-road performance in everyday driving. The plug-in hybrid 4×4 traction system has been designed and developed to perfectly integrate the power supply into the 4×4 traction system, to further improve the off-road performance. The HYBRID mode driving optimisation algorithm is designed to manage the car in the most efficient configuration according to the following factors:
The internal combustion engine turns will only cut in if the driver kicks-down or when the battery level is low.
In case of extended off-road driving, two electric motors featuring Powerloop ensure that eAWD traction is always available.
The 11.4 kWh battery pack allows the Renegade 4xe to travel approximately 26 miles in full-electric, zero-tailpipe emission mode. The Jeep Renegade 4xe features a small charging module, placed in the boot, and the arrangement of the electric motor under the floor means that the boot capacity is almost the same as that in the conventional engine version at 330 litres.
Green, if the ‘Intense’ function is selected and active
In ‘Intense’ mode the regenerative braking calibration is greater when coasting, reducing the speed faster and generating more electricity to be returned to the battery pack.
The new Jeep Renegade 4xe stands out from its internal combustion engine (ICE) counterparts thanks to the striking blue Jeep, Renegade and 4xe badges. As a result of the high torque that can be released onto the ground almost instantaneously from the rear electric motor – up to 2,500Nm – and the possibility of adjusting it with extreme precision during acceleration and when traversing the most challenging terrain, the off-road driving experience is more precise and controlled.
Two electric motors, one of which is located on the front axle and coupled to the internal combustion engine that, in addition to working in synergy with the engine, can act as a high-voltage generator: uses both the electric motor and the internal combustion engine to deliver a sporty driving performance. Jeep Renegade 4xe also features the new Drowsy Driver Detection system, offered for the first time in a Jeep model.
The hybrid system also includes a power inverter (PIM) housed inside the battery pack, which is also protected from damage.
E-SAVE mode supports two secondary modes, called Battery Save (passive E-SAVE) and Battery Charge (active E-SAVE), both of which can be activated on the Uconnect system screen.
Thanks to the new 4xe technology, traction to the rear axle is not provided by a prop shaft but through a dedicated electric motor.Initially, the system favours electric driving, with the power supplied by the electric motor.
With the electric all-wheel-drive technology (eAWD), rear-axle traction is supplied by a dedicated electric motor instead of the prop shaft.By using the My Navigation function, drivers can plan their route the night before and send it to their Renegade 4xe ready the next morning, or schedule their preferred charging times and days or search for and pay at charging stations.
This allows the two axles to be separated and control the torque independently in a more effective way than a mechanical system, with traction being delivered to the rear wheels immediately when needed.
For off-road driving, customers can select HYBRID 4×4 mode and the system will automatically operate both drive systems on both axles.
The electric unit on the rear axle is powered by a battery that can be charged either while you drive or through an external power outlet with a domestic plug and the cable supplied, or from a public charge point using the specific cable.
By integrating the electric motor on the auxiliary belt it was possible to design a control logic that optimises the dynamics and efficiency of the internal combustion engine and the automatic transmission.
An 11.4 kWh, 400 volt, lithium-ion, nickel-manganese-cobalt, battery pack powers the e-axle and is located in a secure position underneath the second row seats
An integrated module for controlling the charging of the high-voltage and conventional 12V batteries of the car which is compact in size and mounted in the boot
The hybrid mode maximises fuel efficiency, achieving between 123 and 134 mpg (with the battery charged).
With its most recent step into the world of electrification, the Jeep plug-in hybrid propulsion solution is capable of enhancing the legendary off-road capability of its line-up of SUVs, starting with the Jeep Renegade 4xe plug-in hybrid.An additional push cover on the vehicle’s left side, towards the rear, covers the charging port and is unique to the 4xe model.
The result is the ability of the Jeep Renegade 4xe to handle every situation in the most efficient, safe and best performing mode.
The Jeep Renegade 4xe arrives in showrooms in the UK in September 2020 priced from £32,600 OTR for a Jeep Renegade 4xe Longitude.
This allows them to access ‘restricted’ traffic areas, as the car will use the electric motor that supplies power to the rear wheels only so the car has zero tailpipe emissions.Smart onboard connectivity – user-friendly and easy to use
Jeep Renegade 4xe was developed to offer state-of-the art technology and connectivity to meet the changing needs of customers.The range of the Renegade 4xe in full-electric is about 26 miles and top speed is of 80mph in full electric.
The internal combustion engine and electric motor work together, with braking energy recovery phases.This allows the Renegade 4xe to be, first and foremost, an authentic Jeep that’s extremely capable and fun to drive, both on and off-road.
When the battery reaches the minimum charge level (State Of Charge – SOC), the internal combustion engine is used for propulsion. Off-road capability and Jeep hybrid e-AWD system
