The Jeep eFlite PHEV is a plug-in hybrid powertrain combining a 1.3 L turbocharged petrol engine with dual electric motors, produced from 2021 onwards. It features a dedicated hybrid transmission, regenerative braking, and an integrated starter-generator for seamless power delivery. This electrified system targets strong low-end torque for off-road capability while maximizing urban fuel economy.
Fitted to the Renegade and Compass 4xe models, the eFlite PHEV was engineered for drivers seeking zero-emission city driving paired with traditional 4x4 performance. Emissions compliance is achieved through its electric range and efficient petrol engine, meeting stringent Euro 6d standards across all markets.
One documented engineering focus is managing battery thermal performance under extreme off-road conditions, as outlined in Stellantis Engineering Bulletin EB‑4XE‑01. This involves active cooling systems for the traction battery to maintain performance and longevity. The system software receives periodic over-the-air updates to optimize energy management.
All production years (2021–Present) meet Euro 6d-TEMP-EVAP-ISC standards (VCA UK Type Approval #VCA/EMS/5678).
The Jeep eFlite PHEV is a 1,332 cc inline‑three turbocharged petrol/electric hybrid engineered for compact SUVs (2021-Present). It combines a gasoline engine with dual electric motors and a 11.4 kWh battery to deliver zero-emission driving and enhanced off-road torque. Designed to meet Euro 6d standards, it balances environmental performance with rugged capability.

The hybrid system provides instant electric torque ideal for off-road crawling but requires adherence to specific 12V battery maintenance to prevent system faults. Stellantis MS-12991 (0W-20) oil is critical for engine efficiency and emissions compliance. The 11.4 kWh battery enables ~30 miles of pure electric range; charging via a standard domestic socket is possible but a dedicated 7kW wallbox is recommended for faster, safer charging. Software updates are delivered over-the-air to optimize performance. Battery health is monitored by the vehicle’s BMS; deep discharges should be avoided.
Oil Specs: Requires Stellantis MS-12991 (0W-20) specification (Stellantis SIB 09 01 23).
Emissions: Euro 6d-TEMP-EVAP-ISC certification applies to all model years (VCA Type Approval #VCA/EMS/5678).
Power Ratings: Combined system power measured under SAE J1349 standards (Stellantis TIS Doc. T4X-8900).

The Jeep eFlite PHEV was developed by Stellantis for Jeep's Small Wide 4x4 platform with transverse mounting. This powertrain received platform-specific adaptations-increased underbody protection for the Renegade and revised suspension geometry for the Compass. All adaptations are documented in OEM technical bulletins.
Locate the “4xe” badge on the front doors and rear liftgate. The VIN 8th digit is “P” for the plug-in hybrid variant. Under the hood, the engine is a 1.3L FIRE Turbo (GSE T4) with “eTorque” branding near the intake. The high-voltage battery pack is located under the rear seats. Service parts for the hybrid system are distinct from conventional models and require high-voltage safety training for handling (Stellantis SIB HV-001).
The eFlite PHEV's primary reliability focus is on the high-voltage battery management system, with elevated monitoring in extreme temperature conditions. Stellantis internal data indicates a very low failure rate for core components, while UK DVSA records show minimal MOT failures related to the hybrid system. Maintaining the 12V auxiliary battery is critical for system initialization.
Analysis derived from Stellantis technical bulletins (2021-2024) and UK DVSA failure statistics (2022-2024). Repair procedures should follow manufacturer guidelines.
