The Jeep eTorque is a mild-hybrid system paired with 2.0L turbo petrol or 3.6L V6 petrol engines, produced between 2018 and 2023. It features a 48V belt-driven starter-generator (BSG) that provides torque-fill, engine stop-start, and energy recuperation, delivering supplemental torque of up to 130 Nm. The system enhances low-end responsiveness and reduces turbo lag.
Fitted to models such as the Wrangler, Gladiator, and Grand Cherokee, the eTorque system was engineered to improve fuel efficiency and drivability without compromising off-road capability. Emissions compliance was achieved through integration with existing gasoline particulate filters (GPF) and engine management, allowing Euro 6d compliance for its production period.
One documented engineering update addressed potential 48V battery module communication faults under extreme thermal cycling, highlighted in Stellantis Service Bulletin 20‑015‑21. This was linked to software calibration and connector sealing. Revised control modules and updated software were introduced from MY2021 production.
All production years (2018–2023) meet Euro 6d standards as per original type approval (VCA UK Type Approval #VCA/EMS/8901).
The Jeep eTorque is a 48V mild-hybrid system engineered for Wrangler, Gladiator, and Grand Cherokee (2018-2023). It combines a belt-driven starter-generator with turbocharged or naturally aspirated petrol engines to deliver torque-fill and seamless stop-start functionality. Designed to meet Euro 6d standards, it balances performance enhancement with fuel economy.

The eTorque system provides seamless stop-start and torque-fill for reduced turbo lag but requires premium unleaded (95 RON minimum) for the 2.0T variant to prevent pre-ignition. Correct engine oil specification is critical for base engine longevity. The 48V system mandates periodic inspection of battery module connections and software updates. Revised 48V control modules from MY2021 address communication faults documented in Stellantis SIB 20-015-21. The GPF system requires low-ash oil to prevent clogging and benefits from periodic highway driving for passive regeneration.
Oil Specs: Requires FCA MS-12991 for 2.0T or MS-6395 for 3.6L (Stellantis Owner's Manual). Supersedes ACEA requirements.
Emissions: Euro 6d certification applies to all production years (VCA Type Approval #VCA/EMS/8901).
Power Ratings: Measured under SAE J1349 standards. Peak output requires 95 RON fuel for 2.0T variant (Stellantis TIS Doc. TIS-ETQ-201).

The Jeep eTorque system was used across Jeep's Wrangler (JL), Gladiator (JT), and Grand Cherokee (WL) platforms with longitudinal mounting. This system received platform-specific adaptations-unique mounting brackets for the Gladiator and revised cooling routing for the Grand Cherokee-and from 2021 the facelifted models adopted updated 48V control modules and software, creating minor electronic interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the eTorque system label on the 48V battery module in the engine bay (Stellantis TIS Doc. TIS-ETQ-005). The presence of a prominent 48V battery and "eTorque" badge on the fender confirms the system. Critical differentiation: Early eTorque systems (pre-2021) use specific control module software; post-2021 units use updated software per Stellantis SIB 20-015-21. Service parts for the 48V system require model year and production date verification.
The eTorque system's primary reliability consideration is 48V system communication stability under thermal stress, with elevated incidence in extreme climate environments. Stellantis internal quality reports from 2021 noted a measurable rate of 48V module faults in pre-MY2021 builds, while owner feedback frequently cites GPF regeneration issues in predominantly short-trip urban driving. Consistent use of correct fuel grade and oil specification makes preventative maintenance critical.
