The Mitsubishi Outlander PHEV combines a 2,360 cc, inline‑four naturally aspirated petrol engine with dual electric motors in a series‑parallel hybrid architecture. The 4B12 petrol engine delivers 93 kW (126 PS) and 199 Nm, while the front and rear electric motors contribute 60 kW and 70 kW respectively. Total system output is 154 kW (209 PS), enabling EV‑only urban driving and AWD capability without a mechanical driveshaft.

Production years 2013–2018 meet Euro 5 standards; 2019–2023 models meet Euro 6d TEMP depending on market .
The Mitsubishi Outlander PHEV powertrain integrates a 2,360 cc Atkinson-cycle petrol engine with dual electric motors and a high-voltage lithium-ion battery system (2013–2023). It enables pure-electric driving up to 54 km (WLTP) and seamless transition to hybrid mode for extended range. Designed to meet Euro 5 and Euro 6d TEMP emissions standards, it balances urban zero-emission capability with highway efficiency.

The Mitsubishi Outlander PHEV powertrain was used exclusively in Mitsubishi's ZJ/GC-series SUV platform with transverse mounting and no external licensing. This system received generational adaptations—revised battery packs in the 2019 facelift and updated power electronics in the 2022 model—creating minor high-voltage component interchange limits. All adaptations are documented in OEM technical bulletins.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
Field reports and technical service bulletins highlight component wear patterns under high-load operation. Adherence to manufacturer service intervals and approved fluid specifications is critical for long-term reliability.
Analysis derived from manufacturer technical service bulletins and industry workshop records. 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 Outlander PHEV is generally reliable, especially post-2018 models with updated battery packs. Early units (2013–2017) are prone to battery degradation if deeply discharged regularly. With proper charge management (avoiding <20% SoC), climate-controlled parking, and 12V battery maintenance, many examples exceed 200,000 km without major hybrid system issues.
Top issues include traction battery capacity fade (early builds), 12V auxiliary battery failure, rear motor inverter overheating, and regenerative braking inconsistency. All are documented in Mitsubishi TSBs and can be mitigated with proper charging habits and timely software updates.
The Outlander PHEV powertrain appears exclusively in the Outlander PHEV (ZJ# 2013–2018 and GC# 2019–2023). It was never licensed to other manufacturers and remains Mitsubishi’s flagship plug-in hybrid system.
No. The hybrid system is tightly integrated and locked by the hybrid control unit (HCU). ECU remapping is not supported, and modifications risk disabling the high-voltage system or triggering safety shutdowns. Most owners focus on battery health and regenerative efficiency rather than power increases.
Excellent when charged regularly. In hybrid mode, expect ~6.1 L/100km (city) and ~5.3 L/100km (highway), or about 48 mpg UK combined. With daily charging, real-world consumption can drop below 2.0 L/100km. WLTP electric range is 28–54 km depending on model year and battery size.
Yes. The 4B12 petrol engine is an interference design. However, it uses a maintenance-free timing chain and operates infrequently under light load, making failure extremely rare. No timing belt replacement is required.
Mitsubishi specifies SAE 0W‑20 oil meeting API SN/ILSAC GF-5 (or ACEA C2). Always use a quality low-viscosity synthetic and change every 15,000 km or annually to protect the Atkinson-cycle engine during frequent start-stop operation.
Comprehensive technical documentation and regulatory references
EngineCode.uk is operated by Engine Finders UK Ltd. It provides engine-reference information and an optional commercial enquiry service. It is not an official manufacturer website. Check the record's sources and confirm vehicle-specific details before relying on it for parts, repairs or replacement.
Our editorial standard prioritises relevant manufacturer documentation and official regulatory sources. The sources and verification status for a record should be checked alongside the data.
