The Jeep EWR – Petrol (eTorque) (Stellantis) is a 3,604 cc, V6 naturally aspirated engine produced between 2019 and 2023. It features port fuel injection, dual overhead camshafts (DOHC), and is paired with a belt-driven mild-hybrid system (eTorque). This unit delivers 213 kW (289 PS) and 353 Nm of torque, with the eTorque system providing an additional 130 Nm for transient response.
Fitted primarily to the Wrangler (JL) and Gladiator (JT), the EWR was engineered for off-road capability and on-road refinement. Its character emphasizes low-RPM torque and smooth power delivery, enhanced by the electric motor's instant torque fill. Emissions compliance was achieved through a three-way catalyst and secondary air injection, meeting Euro 6d standards from launch.
One documented concern involves premature failure of the eTorque belt drive unit (BDU), as noted in Stellantis Service Bulletin 09‑022‑21. This issue is often linked to water ingress or electrical faults in the BDU’s control module. Stellantis addressed this with revised sealing and updated control software in 2022.
Production years 2019–2023 meet Euro 6d standards (VCA UK Type Approval #VCA/STL/9023).
The Jeep EWR – Petrol (eTorque) (Stellantis) is a 3,604 cc V6 naturally aspirated engine with mild-hybrid assist, engineered for off-road SUVs and pickups (2019-2023). It combines port fuel injection with a 48V eTorque belt-driven starter-generator to deliver smooth, linear power and enhanced low-end torque. Designed to meet Euro 6d standards, it balances rugged capability with improved fuel efficiency.

The eTorque system provides smooth stop-start operation and torque fill for low-speed off-roading but requires premium unleaded (95 RON minimum) for optimal performance. Stellantis MS-12991 (5W-30) oil is critical for maintaining variable valve timing performance. The 48V eTorque system's belt drive unit (BDU) is susceptible to water ingress; ensure the engine bay drainage channels are clear. BDU failures were addressed with revised seals per Stellantis SIB 09-022-21; pre-2022 models should have the updated part if replacement is needed.
Oil Specs: Requires Stellantis MS-12991 (5W-30) specification (Stellantis Owner's Manual).
Emissions: Euro 6d certification applies to all 2019-2023 production (VCA Type Approval #VCA/STL/9023).
Power Ratings: Measured under SAE J1349 standards. Requires 95 RON minimum fuel for rated output (Stellantis TIS Doc. S6D-4650).

The Jeep EWR – Petrol (eTorque) (Stellantis) was used across Jeep's JL and JT platforms with longitudinal mounting. This engine received platform-specific adaptations-reinforced mounts for the Gladiator-with no major facelift revisions affecting core compatibility. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front of the cylinder block, near the timing cover (Stellantis TIS S6D-4500). The 8th VIN digit typically indicates engine displacement ('E' for 3.6L petrol eTorque). Visually, the engine features a black plastic intake manifold with '3.6L V6 eTorque' branding and a prominent 48V belt-driven starter-generator on the front. Critical differentiation from the non-eTorque 3.6L Pentastar: EWR has the eTorque BDU and associated 48V cabling. Service parts require VIN verification - BDU components for pre-2022 models differ from post-2022 units due to seal revisions (Stellantis SIB 09-022-21).
The EWR's primary reliability risk is eTorque Belt Drive Unit (BDU) failure, with elevated incidence in vehicles exposed to wet conditions or with blocked engine bay drains. Stellantis internal data from 2021 indicated a notable number of BDU replacements under warranty for early-build vehicles, while UK DVSA records show no systemic emissions failures linked to this issue. Adherence to drain maintenance and using the latest revised BDU part make longevity critical.
Analysis derived from Stellantis technical bulletins (2020-2022) and UK DVSA failure statistics (2021-2023). Repair procedures should follow manufacturer guidelines.
