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.

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 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.
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.
The most common questions about engine codes, what they mean, how to find them and how this database works
The EWR offers strong, smooth performance and excellent off-road capability, but its long-term reliability hinges on addressing the known eTorque BDU issue. Key concerns are the BDU (especially pre-2022) and rear main seal, both sensitive to maintenance. Using premium fuel (95 RON) and changing the oil on schedule greatly improves longevity. Later models (post-2022) have addressed the BDU design flaw.
The most frequent issues are eTorque Belt Drive Unit (BDU) failures, oil leaks from the rear main seal, coolant leaks from the water pump, and variable valve timing solenoid faults. These are well-documented in Stellantis service bulletins, particularly SIB 09-022-21 for the BDU.
This 3.6L V6 eTorque engine was used in the Jeep Wrangler (JL) and Jeep Gladiator (JT) from 2019 to 2023. It was typically badged as '3.6L V6 eTorque'. It was not used in the Renegade, Compass, or Cherokee.
Yes, the EWR responds well to ECU remapping. Stage 1 tunes can safely increase power to around 310-320 PS and torque to 380-400 Nm, leveraging the robust internals. The eTorque system generally remains functional with a tune. More aggressive tuning requires supporting modifications. Always ensure the tune is from a reputable tuner familiar with Stellantis systems.
Official combined figures are around 11.8 L/100km (24 mpg UK) for the Wrangler and 12.4 L/100km (23 mpg UK) for the Gladiator. Real-world economy varies: expect 20-25 mpg UK in mixed driving, heavily influenced by driving style, terrain, and vehicle load. The eTorque system provides modest fuel savings primarily through enhanced stop-start and coasting functions.
Yes. The EWR is an interference engine. If the timing chain fails or jumps, the pistons will collide with the open valves, causing catastrophic engine damage. Fortunately, the chain is designed to be very durable and is not a common failure point.
Stellantis mandates oil meeting their MS-12991 specification, typically a 5W-30 full synthetic. Using the correct oil is crucial for the variable valve timing system's longevity and overall engine protection. Change intervals should not exceed 15,000 km or 12 months.
